Air Conditioning FAQs


How does air conditioning work?

Air conditioning works in a similar way to refrigerators in that they remove hot air from a space and then pump out cool air to decrease the temperature. All hot air is then expelled to the outside of the building.

This is how air conditioning works in the simplest terms, take a look at our blog post about how air conditioning works to discover a more in-depth explanation.

What are the benefits of air conditioning?

There is a wide range of benefits of having air conditioning at your home or commercial premises. The main benefit is that air conditioning units keep you at a constant temperature throughout the year allowing you a more comfortable setting whilst at home or work.

Other benefits of air conditioners include:

  • Better air quality
  • Reduced chances of asthma and allergy attacks
  • Fewer insects inside your property
  • Better sleep
  • Improved work performance
  • Reduced risk of dehydration and heatstroke

Do I need planning permission to have an air conditioning system installed?

Air conditioning installations don't typically need planning permission for homes and commercial properties. However, this is not always the case as sometimes the siting of the condensing unit may need approval from local planning, so all air conditioner installations are subject to a site survey.

How much power does an air conditioning unit use?

Energy usage of an air conditioning system can vary depending on the unit size. New inverter driven units are more energy efficient as they work on demand instead of running constantly at 100%. On a new 2.5kw system, 0.58kw will give you 2.5 kw of cooling, offering your greater energy efficiency than older counterparts.

How noisy is an air conditioning unit?

New inverter air conditioning systems are generally very quiet. Indoor units run between 20-45db, outdoor units between 50-82db.

Do the new F gas regulations apply to me?

Yes, the new F gas regulations apply to anyone with the following types of air conditioning installed:

If you have any 1 system with more than 3kg of refrigerant or more than 12kw in total for one or more of your air conditioning systems, then F gas regulations apply to you. This means your air conditioning system / systems require a regular F gas check.

What should I do if my current air conditioning unit contains R22 gas?

If your system is running on R22 refrigerant gas, you need to consider getting your existing equipment replaced. Other options may be possible but will require a site inspection.


How much does it cost to install air conditioning?

Air conditioning costs can vary depending on the setup you are after and the amount of work that's involved. We offer free quotes on all aspects of air conditioning, for both domestic and commercial properties. Get in touch today and discuss your requirements with us.

Will the office have to be empty to install the air conditioners?

No, your office doesn't need to be empty when we install your systems. We can work around you and will try to cause as little disruption as possible. However health, safety and noise may be an issue. If this is the case certain parts of the work could be done out of hours subject to agreement.

How long will the installation process take?

The installation process of your air conditioning systems can vary depending on the number of systems you are having installed. Generally, 1 split system will take 2 days of work.

Do I have to wait before turning on my new system?

Once we have installed and commissioned your air conditioning, the system will be handed over to you and will be fully operational and ready to use.

What areas do you cover for installing air conditioning?

We offer air conditioning services across Sussex, Surrey and London. With offices based in Horsham, West Sussex and South Godstone, Surrey, we are perfectly placed to work effectively across all three counties.


How often does my air conditioning need servicing?

Regularly serviced air conditioning units will keep your system running efficiently and effectively. If you don't have regular maintenance visits, then you will notice that your air conditioning may not be running optimally, producing less cold air and increasing running costs.

How frequently should my air conditioning unit be checked for leaks?

Refrigerant should be checked at least once a year but we recommend 2-3 visits a year to maintain your system's efficiency.

Water is leaking from my unit - what should I do?

If water is leaking from your air conditioning unit, turn off the system via the controller to stop the system from cooling and producing condensation. Place a bucket or suitable container underneath the unit and eventually, the water leak will subside.

Then, give us a call on 01403 791307 if you live in the South East and we will be out to you as soon as possible.

Why isn't my unit switching on?

There are a number of reasons why your air conditioning may not be switching on. Try checking the following:

  • Is there power to the unit?
  • Is the electrical isolator turned on?
  • Is there a display on the controller (if it is an infrared remote, check batteries)?

If all of these have been checked then give us a call 01403 791307 and we can come and your air conditioning system.
