Air conditioning servicing in Dormers Wells, done properly
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We carry out air conditioning servicing for homes and businesses in Dormers Wells and the rest of Greater London, whatever the make. The work covers multi-split systems, wall-mounted split systems and VRF systems, and people most often call us about warning lights on the indoor unit and systems that need a 6 or 12-monthly leak check.
For a flat or office in Dormers Wells, tell us where the outdoor unit is and how we reach it, so let us know how to get to it. Managed buildings may need the visit booked through the agent.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Your questions about air conditioning servicing in Dormers Wells
Do you cover Dormers Wells for air conditioning servicing?
We do: Dormers Wells falls inside our working area. Just call 07833 053749 or send an email with a few details.
Can I get a fixed-price quote for air conditioning servicing in Dormers Wells?
Start with a short message: the address, what you need and a picture or two. Where pictures aren’t enough, a survey comes first and the fixed-price quote follows.
When is an F-gas leak check required?
Only if the system is at or above the threshold of 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for example, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. At the end, we clear up and show you what we have done.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we’ll gladly show you ours.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

Looking after your system
Once we’ve finished, these simple steps help:
- Diary the next service before this one is forgotten
- Keep doors and windows closed while the system is cooling
- Report drips, smells or noises early
Where the system needs F-gas leak checks, the result is recorded, and the next check is due within the period the rules set. We can diary it for you.
The single most useful thing you can do is keep the filters clean. On many wall-mounted units, the filters lift out easily, and the manual shows how.
