The Specific Requirements of Cooled Server Rooms

The Specific Requirements of Cooled Server Rooms

Businesses of all types and sizes are fairly reliant on computers and servers these days.

From data storage to simply running an internal office network, servers have become a fair staple in just about any industry.

These servers have their own sets of requirements, however, if they are to be used and looked after properly; one such requirement to have them housed in cooled server rooms, which means that these businesses also have a need for specialised refrigeration and airconditioning repair and maintenance services, and of course, services relating to their installation in server rooms.

Here we will discuss what makes a cooled server room an essential investment for just about any business. We will do this by looking at what they are exactly, which businesses make the most use out of them, why they are needed, as well as their benefits.

This will help your business take the right approach to cool its server room; so, let’s get started:

What are Cooled Server Rooms?

Cooled server rooms essentially provide an environment that ensures the protection and longevity of computer server systems.

The hardware that the house produces a lot of heat, and as the needs for this hardware increases in scale, the heat generated by these system increases as well.

The challenge here is that computer systems and heat are two things that typically don’t go very well together, especially when temperatures start to be generated in excessive levels (which is often the case with servers).

This means that server rooms need to have carefully implemented climate control systems that don’t only keep a constantly cool temperature, but also ensure a certain humidity level that is neither too moist or too dry.

To ensure this, server rooms are fitted with specialised air conditioning systems that allow for pinpoint control over their internal climate variables (such as temperature and humidity).

This doesn’t just offer a number of advantages to server rooms (which we will discuss a little bit later on) but is actually a necessity for keeping servers running effectively, without downtime suffered from avoidable damages.

On top of this, server rooms are lockable to keep equipment secure and are generally also fire-proof to ensure that there is a minimal risk of damage caused.

Who Needs Them?

Server rooms come in all shapes and sizes, from compact shelves with single servers to entire refrigerated rooms housing millions of Rands worth of sensitive equipment.

The scale and complexity of cooled server rooms is dependant on the size and requirements of the business using it, making them essential for just about any type of business.

Data Storage Handling

Any business working with data storage and handling generally make use of expensive, highly specialised electronic equipment.

This is as true for data-centres and media houses as it is for large-scale companies that need to store large quantities of client data on electronic equipment.

In such professional settings, the equipment used to store, analyse and retrieve data is the cornerstone of the business using them, and as such, need exceptional care if these types of businesses are to remain in a competitive space; regardless of the size of their operations.

Medium to Large Businesses

Businesses of just about all sizes are reliant on cold server rooms as well, and the more they scale up, the more complex the needs for these server rooms become.

Exceptionally small businesses, whose server may only be a single computer, could probably get away with not having a proper server room or bracket in place. But as operations grow through medium businesses, servers become significantly more complex; and switches, routers, computers and hard0drive shelves start being used.

By the time any business’ tech reaches this stage, the use of a cooled server room that keeps servers and their various components becomes all the more essential.

Why do Server Rooms Need Cooling?

We’ve spoken a bit about the fact that servers need effective cooling solutions; but why exactly do they.

Electronic equipment is highly sensitive to both temperature and ambient moisture in their immediate environment; and while they run, they actually add to the negative variables that can affect their performance or even leave them damaged.

Because of this, there are two major factors that every server setup needs to ensure are carefully controlled.

These factors include temperature and humidity:

Temperature Control

Temperature is an essential point of control wherever computers and their related server equipment is being employed. As they run (and depending on the processing power required for their tasks), enough heat can be generated to actually cause damage to equipment.

In any setting where electronic equipment exceeds temperatures of 90°C, there is a serious risk of failure.

This means that ambient temperatures need to be kept at a respectable minimum, to help with cooling equipment while it is being used.

The greater the processing power, the greater the need for cooling. The greater the need for cooling, the more effective cold server room needs to be.

Humidity Control

Humidity is another concern for cold server rooms since electronic equipment is highly sensitive to excessive moisture in the environment.

It is no secret that water and electronics are not exactly the best of friends, and so humidity levels need to be kept relatively low to ensure that no excessive moisture in the server room presents a risk of damage to equipment.

This doesn’t mean, however, that cold server rooms should be as dry as possible, as too little moisture can create an even greater problem.

If the air in a cold server room becomes too dry, there is a heightened risk of static charges being created on its surfaces.

Electronics are even more sensitive to static charges than they are to moisture, with even the smallest sparkrendering hardware utterly unusable.

Because of this, col server rooms need to find the ideal balance between moisture and dryness in the air.

To offer the best protection possible, the relative humidity in a server room should be somewhere between 40% and 60%.

Other Essential Server Room Requirements

Of course, server rooms fulfil a number of other functions aside from temperature control, which means that their design needs to incorporate a few essential elements at once.

Most important of these include the need for a solution that is relatively fire-proof, it needs to be able to prevent tampering and pilfering, and it also needs to accommodate enough space for every component being used as part of the server, while still offering optimal airflow.

Let’s take a closer look at each one here:

Fire Proof

Let’s go back quickly to the way that electronics and water are never a good mix for each other, and then consider how one would go about dousing a fire should it be in danger of reaching the server room.

Naturally, fire sprinklers and other suppression systems are not a good fit for server rooms because of this.

Therefore, they need to be designed in such a way as to offer exceptional fire protection, to ensure that there is a minimal risk of damage should one break out in the office.


The next important thing to consider is server room security, and every server room or shelf needs to offer exceptional protection in this regard.

Consider the total cost of every piece of equipment within your server room; not just the cost of replacing them should something happen, but the value of their functions and the data they store for your business.

A loss of this equipment, or its functionality, as a result of tampering with the hardware or worse still, having it stolen, can present a possibly fatal challenge to businesses of all types; particularly those that house sensitive information.

Because of this, server rooms need to be easily secured with locks, surveillance and alarm systems that deter theft or tampering.

Available Space

Where the availability of space is a concern for server rooms, there are two things that need to be seen for them to work effectively and to ensure the longevity and performance of its contained hardware.

Firstly, it stands to reason that the room needs to be large enough to accommodate every component that makes up the server. These might include computers, screens, external hard-drive cases, network switches, monitoring hardware, routers and more.

So, the first step when having one designed is to know exactly what type of hardware it will need to encase so that they can be designed to accommodate them comfortably.

This doesn’t mean that as much hardware as possible can be crammed into a server room, you need to remember that cold server rooms only operate effectively when there is enough air flowing through them to cool components and expel any heat generated by them.

Because of this, they need to be designed with accommodation for additional space.

Should the needs of your server be scaled up, it might be worth increasing the capacity of your server room before upgrading the server itself.

The Benefits of Cooled Server Rooms for Businesses

With all of this in mind, you should already be able to see how server rooms can benefit your business.

But let’s take a bit of a closer look at some of the most major advantages that can be gleaned from doing so.

These include the ability to keep equipment properly protected, the ability to fine-tune energy consumption, the ability to easily scale your server rooms for your particular needs, and extending the life-span of your server-related hardware.

Protect Equipment

Server hardware faces a number of dangers from a variety of sources including static, moisture, heat, theft, fire, surges, and accidents; just to name a few.

While the hardware used is generally quite robust, they do require additional protection, especially as they grow in scale and complexity.

The carefully controlled environment offered by cold server rooms ensures that any risks to your hardware are minimised, thanks to their effectiveness at protecting hardware from damage through all of the sources mentioned above.

Fine-Tune Energy Consumption

If energy consumption and running costs area concern for your business, it is good to know that a properly designed server room allows for not only careful and thorough monitoring of the conditions in the room (such as humidity and temperature), but also gives you exact control over those variables as well.

This allows businesses to find a balance between fostering a protective environment for the server room, while also ensuring that running costs are kept at a minimum.


As your business grows and changes, so too will it’s particular needs, and one of the first places where you might need to make adjustments in this regard includes your company’s server.

While server rooms are complex and specifically designed to fit particular business environments, they are generally not set-in-stone.

They are generally designed to be easily adapted to the growth of a business, as the requirements for hardware and performance increases alongside the capacity of the business itself.

Extend Equipment Longevity

Excessive heat in a server room may not necessarily damage equipment immediately. Often enough, excessive temperatures simply result in a significant shortening of the hardware’s lifespan.

Depending on the severity of the setting, hardware’s lifespan can be shortened by anything between months to years.

By providing the ideal climate for hardware to operate in, therefore, you can significantly extend the years of use your business gets out of them.

What are Heat Exchangers?

Heat exchanger services form the backbone of many applications across both the industrial sector and the commercial one.

There is a high need for effective, efficient and economical systems that allow businesses to enact fingertip control over internal temperatures; whether those be as part of a refrigeration system, a fluid control system, or even when looking to manage uniform temperatures throughout a facility.

Heat exchangers have become an important component in just about all systems that seek to achieve this type of control, which makes their widespread use no surprise, regardless of the industry it is servicing.

Because they form a crucial part of just about all applications in certain industries, we will explore them in more detail here. We will look at what they are, their different types, and how they benefit businesses.

So, let’s get started:

What are Heat Exchangers?

Heat exchangers come in a variety of types depending on your needs for them, each with their own unique functions, properties, advantages and setbacks.

However, even with these differences in types, heat exchangers always work to perform a similar function. In a nutshell, they form part of a system where temperatures need to be transferred from one point to another.

This is typically done through the use of two different fluids within the heat exchanger. These fluids might come into contact with one another to do this; however, there are also situations where these two fluids will not make contact with each other, in being separated by a wall within the system to prevent them from making direct contact during the process of exchange.

These fluids are generally either water or oil thanks to their thermal conductivity which makes the process all the more effective.

Wherever a fluid is being used in heat exchangers, they need to have a fairly low viscosity to ensure that the fluids flow uninterrupted, while also having the exceptional thermal capacity to ensure that heat is adequately transferred through the liquid.

How do Heat Exchangers Work?

Heat exchangers are an excellent approach to conserving energy in a factory or plant thanks to allowing the facility to make the most out of the heat that it produces, it also allows for effective cooling by eliminating heat from a system where necessary.

Of course, they aren’t only used for these processes, having their places in everything from in our homes to being used in cars and planes.

A heat exchanger will transfer heat from one fluid to another without having them come into direct contact. Quite simply, hot fluid will flow through a coiled tube within the device.

Another, much colder fluid runs through the device in the opposite direction allowing for the heat exchange to take place without creating any points of direct contact.

This way, the fluid that entered into the shell at a high temperature will exit the other end cooler than before, while the cool liquid will exit the other end at a higher temperature.

This, of course, is a very basic description that accounts for just about all types of heat exchangers. Different types will provide functionality through slightly different processes, however. But we will explore these in more detail a little later on.

Why are Heat Exchangers Used?

There are a number of reasons to use heat exchangers, and these reasons span across a number of industries and settings.

From right here in our own homes, to our offices and factories, right through to the vehicles we use to travel between them; heat exchangers form a crucial part of almost all aspects of our lives.

Their two major purposes include heating and cooling.

Imagine for a second, you need to heat an entire building through the use of a boiler system. Using a heat exchanger service, you can ensure that this heat is distributed effectively through the fluids within a piping system; whereby the water or oil can be heated by the burner and sent to each part of the structure.

Heat exchangers also work for cooling, such as in refrigeration, air conditioning or climate control inside of facilities and homes; even your air conditioner uses a heat exchanger to ensure that it can effectively cool and heat the air that it provides.

Of course, heating and cooling are fairly simplistic terms in this regard. The way that heating and cooling are conducted by a heat exchanger, and for what purposes, will be dependant on the type of environment it is being used in.

Which Industries Require Heat Exchangers?

As you can imagine, heat exchangers are used across a multiverse of industries. These components are essential, even if often overlooked in their capacity to enhance productivity and enact exact control over certain environments.

While they are also used in various domestic applications (such as in air conditioners and fridges), here we will explore their use in the industries that have a strong reliance on heat-exchanger services that meet their exact needs.

Waste-Water Treatment

Heat exchangers are used extensively in waste-water treatment. The process of treatment releases a lot of energy in the form of heat. Without the use of heat exchangers, this energy goes to waste, accounting for a rise in costs and also contributing significantly to the destruction of the local environment.

Using heat exchangers in such situations allows this heat to be reintroduced into the facility from where it can be used for a range of heating and cooling activities.

Food & Beverage Industries

The food and beverage industries are wholly reliant on methods used to keep perishables (whether they are finished products or ingredients) fresh.

This need for cooling is not limited only to production, there is also the matter of keeping produce fresh during storage, as well as during transport.

This calls for a need for specialised airconditioning and refrigeration systems that are designed to protect the condition of produce during every step; from production to take it to market.

These systems, as you may have guessed, are reliant on effective heat exchangers for their functionality.

Petrochemical Plants

Petrochemical plants have a dire need for exact environmental control, particularly where temperatures are concerned. They work with highly volatile substances, as well as those that need to adhere to strict quality control conditions which need to be carefully managed at all stages of production.

On top of this, much like in water treatment, petrochemical processing generates a staggering amount of heat, heat which can be considered wasted energy if not properly harnessed through heat exchangers.

Wholesale & Retail

Walk into any supermarket and one of the first things you notice is the staggering dip in temperature as you enter the door.

Then there are the large-scale needs for specialised refrigeration to keep everything from dairy to meat products fresh.

Each of these systems needs to manage temperatures effectively and economically through the use of heat exchangers; providing outlets with a solution for consistent temperature control at less of a cost.

Types of Heat Exchangers Available

It is plain to see that heat exchanger services have a crucial role to play in many different aspects of our personal and professional lives. Since their use and application is so varied, it stands to reason that there isn’t a one-size-fits-all product that meets the needs of every conceivable industry.

There are, rather, a range of different types, each with their own unique properties, applications, benefits and drawbacks.

Let’s explore a few of them here:

Plate Heat Exchangers

Plate heat exchangers use metallic plates to create a much larger surface area to facilitate more effective heat transfer between them.

They allow their operators an additional level of flexibility since their rate of heat exchange can be altered by adding or removing plates from the system individually.

This also makes them fairly easy to clean and maintain, since they can be disassembled without too much effort.


Plate heat exchangers offer a number of unique advantages wherever they are used. They are exceptionally efficient, compact and scalable.

They are also fairly easy and affordable in terms of maintenance, making them a great investment for long-term cost saving.


Of course, plate heat exchangers also come with a few disadvantages that you might want to be aware of before sourcing any.

For starters, they are not the most effective solution where sealing is concerned; which leads to quite a bit of leaking, especially when maintenance is overlooked.

They are also fairly limited in terms of their operational pressure and temperature thresholds, which are dependent on the materials used in the plates themselves.

Shell & Tube Heat Exchangers

Shell and tube heat exchangers operate exactly according to the description given near the beginning of this article.

A cold fluid enters one end of the shell through a tube that separates it from a hot fluid in the shell. As it does this, heat is exchanged from the hot to the cold fluid.

This makes the cold fluid come out hotter when it exits, while the hotter fluid loses temperature as it does the same.


Shell and tube heat exchangers come with a number of advantages.

They are able to withstand remarkably high operational pressures. They are very robust but also offer flexibility in terms of design.

Their temperature threshold also works on a fairly wide spectrum, being well suited to extremely high or low temperatures.


Like any other exchanger, shell and tube heat exchangers have one or two drawbacks to consider.

For instance, they do not distribute heat as effectively as plate heat exchangers, their tube cooler capacity cannot be expanded, and they take up quite a bit more floor-space than other solutions.

Tube to Fin Heat Exchangers

These types of heat exchangers use fin-type chambers and plates to allow for the transfer of heat between two different fluids.

This allows them to make the most out of the surface area when it comes to effectively transfer heat between them through a solution that is not only very effective but also compact and well suited to high volume transfer ratios.


These types of heat exchangers offer an impressive increase in the outer surface area of the tubes, which in turn improves the rate of heat transfer offered by the system.

This is the single most beneficial feature of the tube to fin heat exchangers and marks them as the ideal solution for specialised applications.


Of course, like any of the abovementioned solutions for heat exchange, these tubes to fin heat exchangers do come with one or two disadvantages that you should be aware of when mulling over candidate solutions for your temperature control needs.

Cleaning and maintenance represent the biggest drawback of this technology since it isn’t particularly straightforward or simple.

This is because of the mechanical fins which may hold on to debris a little more stalwartly than you may like. This means that when it comes time for maintenance to be conducted, it is best handled by a provider of heat exchange services if it is to be done effectively.

Heat Exchangers for Flow arrangement

There are three primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. In counter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current design is the most efficient, in that it can transfer the most heat from the heat (transfer) medium per unit mass due to the fact that the average temperature difference along any unit length this higher.  In a cross-flow heat exchanger, the fluids travel roughly perpendicular to one another through the exchanger

What are different types of Heat Exchangers?

Heat exchangers come mainly in the following types to mention a few (i ) Braised Plate Heat Exchangers , (ii) Gasket Heat Exchangers

Efficiency that gives a competitive edge

Brazed plate heat exchangers are one of the most efficient ways to transfer heat. They are designed to provide unparalleled performance with the lowest life-cycle cost. Choosing brazed technology for your next heating or cooling project will bring many benefits, including savings in space, energy, and maintenance.

Advantages Gasketed Heat Plat Exchangers 

Economical, low-capital investment, Easy to install, Heavy duty, Low maintenance costs, Compact modular design


Dirt in the systems, ice formation in refrigerators and mechanical damage are the reason to failure in heat exchangers

Why Heat Exchangers Need to be Kept in Top Condition

Heat exchangers have a limited lifespan (albeit quite a few years) and thusly require a little maintenance from time to time. This is as true for furnaces in industrial facilities, as it is for those being used to heat houses.

The condition of your exchangers can generally be gauged from the colour of the flame put out by your furnace, with a blue flame being indicative of a properly functioning one, while yellow flames generally point to cracks or damages which, if left unattended, could pose a number of health risks to those living and working in the area.

When this happens, it is absolutely crucial to have your heat exchangers repaired or replaced as soon as possible, lest the following dangers lurk in your living or working areas.

Carbon Monoxide

A faulty heat exchanger may result in too much carbon monoxide being produced by the furnace. When this devilish gas fills an area, it can be risky, even deadly to those within it.

Carbon monoxide poisoning can result in a range of unpleasant symptoms, including headaches, weakness, dizziness, confusion, blurred vision and a loss of consciousness.

Carbon Dioxide

In high concentrations, carbon dioxide can kill people, but generally you will experience a number of other side effects long before that happens.

Shortness of breath, heart palpitations and a loss of consciousness are included here. The danger is that carbon dioxide is tasteless and odourless, making it difficult to detect even in high concentrations.


Soot may seem harmless enough, but in high concentrations it can cause irritation to the lungs, skin and eyes. In addition, if it enters the blood-stream, it can result in respiratory issues and even death.

These are a few good reasons to ensure regular heat exchanger maintenance on your furnaces. For details on having it done professionally, visit the Centromac South Africawebsite today, or contact one of our representatives for details.

Cooling Down the Right Way

When we go along with our lives, there are a few essential elements in our homes that assist in making live just that bit easier. Equipment such as a microwave, stove and maybe even a blender but the most important is a refrigerator. 

Think about it, if we were still stuck back in the cave men era we would have to find alternatives in the preservation of our food and it would not be the freshest. With the help of refrigerators, we do not need to fuss we just look at the expiry date on the back of the packaging. 

However imagine if the simple job of refrigeration could not be met due to malfunction. That is not an issue with this refrigeration and air conditioning company.

When we just need a bit of help

As our everyday lives go on, so does the live of the equipment we use. 

Let us face it when we work for a long time we get to the point where we can find ourselves a bit exhausted or we may get a bit sick, the same goes for our equipment. 

There are many factors that can influence the lives of the equipment we use. When we have our classic power outages, a refrigerators can no longer preserve our food. 

However that is temporary. Within a refrigerators system there are factors that can influence the function. Damage can occur in many ways, such as ice formation in the heating element; erosion or dirt. This simple factors can use the entire system to malfunction. 

That is when we need the help of a professional. With the help of this refrigeration and air conditioning company there is no longer an issue that can’t be solved. 

Get the help you need today!

As we all know, we can’t always keep up the lives of the equipment we use. Sometimes they get damaged or just need some assistance. 

With Centromac Refrigeration there is no distance to far either. Any issue that one may find with their refrigeration or air cooling systems can be solved from Johannesburg all the way to Cape Town.

Keeping it cool

As we all know the preservation of our goods that we buy at the shops, is key. As not all foods and drinks have the same preservation period however we can definitely influence the time that these products survive. 

This is done through the everyday use of our modern kitchen appliance, the fridge. 

Through the use of a cooling system, we are able to keep our goods in a condition that allows them to survive until their expiry date catches up. However the expiry date of our refrigeration may catch up on us and thus resulting in repair. Fortunately, that can be done in Johannesburg and as far as Cape Town.

How it all works

When a refrigerator is plugged in, the system thus begins. The compressor tightens the refrigerators vapour which raises the pressure as this occurs it pushes this pressure into the coils. When the cool air meets the hot coils it becomes liquid. 

Through this process, cool air is created which allows the contents of the fridge to be cooled. 

Why you would need a repair

If the cool air had to access the hot coils of the heat exchanger it would cause the formation of ice thus causing the damage of the heat exchanger which causes the life of the fridge to end. Well temporarily, all you would need is one quick and easy repair that can be done at a refrigeration and air conditioning company.  

Something as simple as dirt can even cause ones fridge to give in. If a fridge had a fault in the cooling and heating water systems due to the design of the refrigerators when dirt enters in the systems. 

Through the use of long operation of the refrigerator this can result in the end of days for the fridge as the dirt halts the system.

Determining When to Replace Your Refrigerator

A good refrigerator can last for years, but at some point all refrigerators begin to break down or become burdensome. The decision of whether or not to replace your old refrigerator rests on multiple factors, including the amount of disrepair, the environmental impact and your own personal needs.

Type of Refrigerator Some types of refrigerators are more difficult and costly to repair than others. For instance, built-in refrigerators are usually less expensive to repair, but side-by-side refrigerators may be good candidates for replacement if they are well over five years old. Faulty bottom freezers should be repaired within seven years and considered for replacement after that. Faulty top freezers should usually be replaced if over seven years old.

Age A typical refrigerator has a 10-20 year lifespan. The longer you have had your refrigerator, the greater the potential repair cost. If the refrigerator is less than eight years old, consider repair. If the refrigerator is more than 15 years old, consider replacement. If the fridge is between eight and 15 years old, you must take the other factors into consideration.

Energy Efficiency Your refrigerator can cost you money in more ways than just repairs. You could be sucking up unnecessary power and facing high electric bills. A 10-year-old fridge uses twice the energy of a green-fridge. If you have an old refrigerator, you might want to invest in a green-refrigerator just to cut back on electricity usage and costs. This can, not only benefit your wallet, but the environment as well. The type of fridge also makes a difference in terms of energy usage. For example, manual defrost units consume less energy than automatic defrost units, if properly maintained, and units with top-mounted freezers typically use less energy than units with bottom freezers or side freezers .

The amount of damage to your current unit must also be considered. If you have several faulty parts or if the unit is simply old, it’s time to replace. If you still have an extended service plan or warranty in effect, always try to make a claim before getting rid of the fridge, but if you have had the unit for close to a decade or more, you most likely have no active warranties. If you still can’t decide, contact an appliance repair expert for an estimate. You can then determine whether the cost of repair would justify keeping your current unit or investing in a new one.

Health Benefits of Air Conditioning

There are so many health benefits to air conditioning, particularly for those who live in hot climates like South Africa. Simply buying an air conditioner can make a huge positive difference on your health. Air conditioning can create a good, clean, healthy environment, and deal with problems like dust, allergies, and help those suffering from unbearable conditions to have a greatly enhanced standard of living.

Basic benefits of air conditioning
Air conditioning is one of the greatest innovations in healthy living environments. The people who get the most benefit from air conditioning in health terms are:

  • People with respiratory conditions.
  • People with allergies to airborne particulates.
  • People under temperature stress from the environment.
  • People living in areas subject to a lot of air quality issues.
  • People with limited mobility.
  • People who suffer from sinus, and similar infuriating conditions.

Your air, your health
Everybody is subject to basic environmental conditions which need management. Even people in excellent health can suffer from temperatures and the invisible airborne particles which are present in every building and human environment. Fumes, insecticides, and other problems need to be managed. Even basic odours are the symptoms of needing better air quality. A smell indicates chemically active particles in the air. These issues aren’t necessarily toxic, but they don’t do much for your breathing. A modern air conditioner can solve all of these problems.

Temperature and comfort
Fatigue can be caused by excessive heat or cold. You can get minor, but repetitive conditions like headaches, colds, discomfort, coughing, and other elusive symptoms. Temperature and humidity affect the bodily functions. Too much heat or cold can use up energy, quite rapidly in some cases. You can feel tired, and not be sure why. You can get dehydration from a low humidity environment, or from an environment which is too humid, which in-return makes you lose water as your body tries to adapt to the environment.

Long term benefits of air conditioning
Constant, repetitive stress on your body doesn’t do your immune system much good, either. Over long periods, the result is wearing down your resistance to these nuisance conditions, making you more vulnerable to infections. Long term air conditioning, on the other hand, also reduces stresses over a period of time, allowing full recovery, and ending the repetitive cycle of conditions. Installing a reliable air conditioning system can make the world’s difference.

Heating and Cooling Technology

You probably know all about the latest smartphones, tablets, and TVs as well as the newest updates in your favourite holidays. But, if someone asked you to name an improvement in HVAC technology in the last ten years for heating and cooling your home, there’s a good chance you wouldn’t be able to come up with anything.

However, if someone asked you if it’s better to know about things that cost you money or save you money, you’d probably pick saving money. With that in mind, take a few minutes to learn about the latest advances in HVAC technology that can slash your energy bills and open up room in your budget for those new gadgets.

Smart Thermostats
These days, there’s an app for everything, and your heating and cooling systems are no exceptions. The fact that you can save money by using a programmable thermostat to turn down the thermostat when you’re at work or sleeping is old news. Today, your thermostat can think for you.

Instead of programming a set schedule, you spend a few weeks telling your thermostat when you wake up, leave, and come back, and go to bed. After that, it automatically adjusts the temperature for you based on the day of week, time, and outside temperature.

You also don’t need to worry about coming home early to a hot house or forgetting to cancel the programming while you’re on vacation. Simply log on to your phone app from anywhere at any time to tell your thermostat where you are.

Variable Speed Blowers
One of the most common reasons people crank up their thermostats and let their energy bills rise is because they feel hot or cold when the HVAC system shuts off between cooling or heating cycles. Variable speed blowers help eliminate these temperature swings.

Instead of simply turning on and off, a variable speed blower runs at high speed when the home’s temperature needs to be changed and then slows down to a holding speed once the desired temperature is reached. This allows the thermostat to be set at a lower level and saves energy even though the overall running time may be longer.

Improved Heating and Cooling Efficiency
Not all furnaces and air conditioners are created equally. Just like different cars have different gas mileage, different HVAC systems use different amounts of energy to heat or cool a home.

Heating efficiency is measured by the Annual Fuel Utilization Efficiency rating (AFUE). It measures the amount of energy that is used by your furnace that is actually turned into heat. For example, an AFUE of 80% means that 80% of the energy a furnace uses is turned into heat and 20% of the energy is wasted.

For furnaces manufactured after September 2015, the Department of Energy mandates a minimum AFUE of between 80 to 84% depending on the fuel type and whether the furnace is designed for a mobile home or permanent structure. The Federal Trade Commission requires the efficiency rating to be displayed on the packaging so that you can compare models and calculate the energy savings from switching to a more expensive, but more efficient, furnace.

Cooling efficiency is measured by the Seasonal Energy Efficiency Ratio. It is calculated by dividing the annual cooling output of an air conditioner by its annual energy use. The higher the SEER rating, the more efficient the air conditioner.
