    How air conditioning works

    Air conditioning works by circulating refrigerant through coils. The evaporator coil absorbs heat indoors, while the condenser coil releases it outdoors via compression and expansion, creating cooler air indoors.

    Indoor Unit

    These units are positioned at an elevated level, ensuring an even distribution of air throughout the room. They operate quietly, ensuring that your sleep or enjoyment of your favorite Netflix show remains undisturbed.

    Outdoor Unit

    These units extract heat from the indoor space and expel it outdoors. The outdoor component can be mounted on an external wall, placed on a roof or balcony, or situated on the ground within your property, such as in a garden.

    Frequently Asked Questions

    One of the main reasons air conditioning stops working or doesn’t work as it should, is inadequate maintenance. Allowing filters and coils to get dirty puts a strain on the system and can reduce its efficiency, as well as put occupants at risk from airborne irritants and pollutants that would usually be filtered out by the system.

    There are numerous warning signs that there is a lack of air conditioning maintenance. Barnet Climate Control advises to look out for…

    Leaking water – Clogged drain lines and general neglect can lead to leakages from air conditioning equipment. This can be very dangerous, as it can damage the units, as well as your property.

    Unusual noises – noisy a/c systems are a clear sign that regular servicing has been lacking. From clogged debris to loose parts, there are all sorts of issues that can cause the likes of clicking, banging and screeching.

    Bad odours – no one wants to work in an unpleasant-smelling environment. But if your air conditioning isn’t regularly serviced, it could lead to dirty filters and other more serious issues that lead to mouldy or musty odours.

    More expensive energy bills – if your energy bills are abnormally high following the use of your air conditioning system, it could well be down to inefficient operation. This may be caused by a build-up of dust and debris, putting a strain on the components and forcing them to work harder to achieve the same levels of cooling, which ramps up the energy usage.

    All of the above issues can potentially be avoided courtesy of a regular air conditioning maintenance

    For residential air conditioning maintenance, Barnet Climate Control recommends a service once per year. For commercial installations in daily use, we advise a service visit around 3-4 times per year.

    Regular servicing helps cut down the need for emergency air conditioning repairs, as well as making it more energy efficient.

    The Energy Performance of Buildings (England and Wales) Regulations 2012 ( require that all air conditioning systems with an effective rated output of over 12kW must be inspected at least every five years. The inspection will highlight any areas for operational improvement, or any recommendations to replace older, less energy efficient systems.

    Those responsible for the operation of the air conditioning system hold a statutory obligation and duty of care to the running and maintenance of the system. Inspection, maintenance and cleaning programmes are required to ensure the system can provide healthy and comfortable environments for building occupants, limiting the escape of refrigerant gases and ensuring equipment safety.


    The F-gas Regulation ( guidance-for-users-producers-and-traders) further sets out provisions for the reduction of use of hydrofluorocarbons (HFCs), which are often used as the refrigerant in air conditioning systems. The Regulation also sets out obligations regarding keeping emissions to a minimum, which include maintenance, regular leak checking and repairs by F-gas qualified engineers.

    Further information on air conditioning inspections in buildings under the Energy Performance of Buildings (England and Wales) Regulations 2012 can be found at

    As part of the air conditioning maintenance, Barnet Climate Control will undertake a number of tests to check the overall performance of the system, and give it a good clean.

    Tests include a check of the electrical wiring; inspecting and cleaning the motors; checking and cleaning the condenser coil; adjusting any belts and pulleys that may have become loose; ensuring there are no blockages within the drains, and checking for F-gas leaks, as well as cleaning or replacing filters as necessary.

    The Barnet Climate Control team is trained to ensure minimal disruption, particularly where working in workplace or public environments.
