How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes anything from a day for one room to several days for a multi-room or ducted system. In a London area like Wallington, parking and access are worth sorting out before the day.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
How to prepare
- Let us know where we can park and unload
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Arrange for someone to be there to let us in

How we handle air conditioning in Wallington

Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
In Wallington, as across London, the rooms that get hottest are normally under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

After we have gone
Looking after the system is mostly common sense. Our tips:
- Book an annual service
- Shut doors and windows when it’s on
- Keep the handover documents somewhere safe
We show you how to take the filters out and clean them. In busy periods, clean them every few weeks, or as the manual recommends, and keep the outdoor unit clear of leaves and clutter.
Don’t ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are normally simpler.
FAQs for Wallington
Do I need permission to put air conditioning in my flat in Wallington?
Often, yes, but the lease and the freeholder usually have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is Wallington in your area for air conditioning?
Yes. Wallington is one of the places we cover. Get in touch with the details and we reply the same working day.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
How long does it take to fit air conditioning?
A single-room system is normally fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
What size air conditioning unit do I need?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Different systems, different jobs
Offices, shops and commercial rooms
Commercial rooms often need more than one unit and controls that suit how the space is used. We size for the people, equipment and glazing in the space and we plan the installation around your opening hours where we can.
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, and the condensate drain carries it away. If gravity won’t do it, a condensate pump is fitted and we allow for that in the quote.

Landlords, agents and facilities managers
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
We also work for facilities teams in offices, schools and public buildings across Greater London. Larger buildings can be done in stages to keep disruption down.
