The Benefits of Office Air Conditioning

There are multiple benefits of installing air conditioning in your office. We all perform better at work when we feel comfortable. Office air-conditioning systems help to ensure that your office is kept at a comfortable temperature all year round, whether you need cool air to refresh you from a summer heatwave or require heat to protect your workforce and equipment from the cold.

It’s not just a question of comfortable temperature, however. Office air conditioners also serve to filter out any pollutants, dust particles and allergens from the air, reducing the risk of respiratory problems and allergies among your team.

Of course, it’s also important to protect your office equipment from extreme temperatures. If your office is filled with computers or other essential business equipment, air-conditioning systems can be used to prevent them from overheating, ultimately saving you from potentially devastating damage and data loss.

Office air conditioning is a great way to lower your energy bills whilst also doing your bit for the environment. Because the modern air-conditioning systems supplied by MAC are capable of producing a greater temperature output than the energy they take in, they are incredibly energy efficient, meaning that over time, you will pay less, whilst also reducing your carbon footprint.

Choosing The Right Office Air Conditioning

Think your office could benefit from one of our top-of-the-range air-conditioning systems? We’ve made a handy online office air-conditioning calculator to help you find the right AC units for your needs. Simply go through the questions online to get your own personalised recommendations and free quote.

Interested in learning more about how our recommendations work? We take your individual circumstances and requirements into account, in order to ensure that we supply and install systems that are right for you. This includes considering the size of your space to determine the right heating and cooling capacity, as well as considering the type of system that most closely matches your needs.

Office Air Conditioning Units

Whilst central air-conditioning systems use a central unit to cool your entire office, they require extensive ductwork to distribute the heated or cooled air, making them more expensive than other types of office aircon systems. As such, they tend to work best in larger commercial spaces and company offices.

Both split and multi-split systems can be installed without the need for any ducts and are a flexible choice that can be easily adapted to different office layouts. Whilst split systems work best for single rooms or small areas, multi-split systems are perfect for multi-room areas or offices with unusual layouts. They usually consist of one single outdoor unit and one or more indoor units, all connected to one another via a refrigerant flow system. Each indoor unit can be controlled individually, on demand. These systems are often referred to as VRF (Variable Refrigerant Flow) or VRV (Variable Refrigerant Volume) systems.

Portable office air-conditioning units are useful in certain circumstances, but we recommend limiting them to temporary use.

What is Office Air Conditioning?

Want to find the best air-conditioning units for your office? Ultimately, it all depends on the type and size of space you are looking to heat and cool. If you have a single room or smaller office, you should be ok with our split office air-conditioning systems, which consist of one outdoor unit connected to one indoor unit. However, if you have a larger office or an office with multiple rooms or zones, a multi-split system is likely best. Like split systems, multi-split systems consist of one outdoor unit, but this is connected to several indoor units, each of which offers individual temperature control.

If you would like further guidance on choosing the right air conditioning for your UK office, why not use our handy online commercial calculator. It will ask you a series of questions to determine your requirements and recommend the perfect product, before issuing you with a free, no-obligation quote. You can also get in touch with our experts for free, impartial advice.

Yes, absolutely! There’s nothing worse than trying to concentrate in a poorly ventilated office, especially during the summer months where windows and fans make little difference to the temperature inside. With office air conditioning, you can help your employees to keep their cool even on the hottest of days, ensuring that they remain healthy and don’t become dehydrated. As such, office aircon can help you to fulfil your duty of care, too. Plus, the more comfortable your team is, the more productive team members will be, too.

Of course, air conditioning is also essential in buildings with lots of computers, servers and electrical equipment. It plays a key role in ensuring that things don’t overheat, insuring you against potentially devastating data loss.

Contrary to popular belief, office air conditioning is not just for hot weather. It is also one of the most reliable and cost-effective methods of heating your office, allowing you to maintain a constant, comfortable temperature throughout the year. All the office aircon units supplied by MAC are incredibly energy efficient, producing a higher output than the energy they consume. This means you should be able to reduce your energy bills, in addition to lowering your carbon footprint, which is absolutely essential in the modern business world.

Finally, office air conditioning systems also help to purify and dehumidify the air. Helping to keep both mould and potential allergens at bay, this ensures a healthier workforce and working environment for all.

The exact mechanisms of your office air conditioning will depend on the type of system you choose and install. However, most systems operate on a basic refrigeration process.

Office air conditioners essentially remove the heat from your office before transferring it outside.

You will have an outdoor unit that contains a compressor, which serves to compress the refrigerant contained inside your system. This compression raises the temperature and pressure of the refrigerant, causing the gas to flow into the condenser coil, where it can release heat into the outdoor air, before turning into a liquid.

The resulting liquid will then flow through a metering device, which lowers the pressure and causes it to evaporate back into a gas in the evaporator coil, contained within your corresponding indoor unit(s). As the refrigerant evaporates, it absorbs heat from the indoor air, cooling it down and causing the cycle to repeat itself again.

When this process is carried out in reverse, it allows you to heat your office instead. In heating mode, the refrigerant absorbs heat from the outdoor air and releases it inside the building, providing warmth.

Yes. We generally recommend closing your windows and doors when using your air conditioning system, as this allows it to run much more efficiently. This is because air-conditioning systems work by removing heat and moisture from the indoor air and replacing it with cool, dehumidified air (or the reverse, if used for hearting). When windows and doors are left open, warm, humid air continues to enter your space, making it more difficult for your aircon units to maintain a comfortable indoor temperature.

Leaving your doors and windows open can also allow outdoor pollutants to enter your office, which can negatively impact indoor air quality and potentially cause health problems for your employees, counter-acting the air purification benefits that office air conditioners provide.

That being said, it’s important to ensure your office is property ventilated, even when using air conditioning systems.

It can be difficult to decide where to place your indoor office air-conditioning units. Luckily, the experts at MAC have plenty of years of experience and know exactly what to look out for. For instance, it’s important to place your aircon unit in a central location if you want air to distribute evenly throughout your space.

It’s also best to avoid placing units near windows and doors if you can, as this can cause air to escape, making your systems work harder to maintain the desired temperature. Likewise, you should avoid placing your air conditioners near heat sources like radiators, computers, copiers and servers for the same reasons.

Height is another major consideration. Ensure that your units are fitted high enough to facilitate optimal air flow (usually between 1.5 and 2.5 metres, unless designed for specific applications).

When you book your office air-conditioning installation with MAC, we will take all these factors into consideration for you, ensuring that everyone in your office will derive maximum benefit from your new systems.

Air conditioning is one of the most effective ways to cool your office. Whilst opening windows can make some difference when it’s mild outside, in hot weather, it’s difficult to draw in fresh air. In fact, the air outside can often make your office hotter.

Fans are another common alternative to air conditioners, but unless there is sufficient air flow within your office, you are just circulating stale air.

Of course, office air conditioners also help to purify the air and remove any allergens, making them more effective at cooling your office than open widows, as you won’t cause any respiratory problems among your staff.

There is no specific law in the UK that states that employees must be sent home if it’s too hot. However, employers do have a duty of care to provide safe and comfortable working conditions for their employees.

In addition to ensuring you have adequate ventilation and air-conditioning systems, we recommend providing access to cool drinking water, allowing regular breaks and encouraging workers to wear lightweight clothing in hot weather.
