Air conditioning servicing in Childs Hill, done properly
Servicing does not mean topping up refrigerant. Refrigerant runs in a sealed circuit and shouldn’t need adding to. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. We’re often asked to deal with noisy fans or rattling from the outdoor unit and weaker cooling than last year, across wall-mounted split systems, air-to-air heat pumps and ducted systems.
Commercial systems in a London area like Childs Hill may need F-gas leak checks as well as a service, depending on how much refrigerant it holds. The check is recorded, with the next date noted.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Looking after your system
Every system needs looking after, and most of it is easy. Our tips:
- Know your manufacturer’s servicing conditions
- Keep plants, bins and stored items away from the outdoor unit
- Make sure the condensate outlet can drain
When we finish, we leave a record of the visit, listing the work, the checks and any recommendations. Keep it with the manufacturer’s paperwork so you have the whole history together.
Book a service at least once a year, and more often if the system works hard or the rules require it.

Questions from Childs Hill
Can you do air conditioning servicing in Childs Hill?
Yes, Childs Hill is within the area we cover. Get in touch with the details and we reply the same working day.
How often do you service systems in Childs Hill?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we will gladly show you ours.
When is an F-gas leak check required?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. From 5 to under 50 tCO2e, leak checks are required at least every 12 months, and from 50 to under 500 tCO2e every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Let and managed properties
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
We also work for facilities teams in offices, schools and public buildings in Childs Hill and across Greater London. Work can be phased by floor, zone or building around the people who use them.
How the visit works
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. The work takes anything from an hour for a simple split system to most of a day for a larger installation. Send us a few phone photos and we can often price a straightforward job in Childs Hill before visiting.
