Chalfont St Peter: your questions answered
Can you do air conditioning servicing in Chalfont St Peter?
Yes. We work across London and the South East from our base in East Grinstead, and Chalfont St Peter is part of that. To start, ring 07833 053749 or use the quote form with a few photos.
Will you come out to Chalfont St Peter?
Yes. Chalfont St Peter is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Do you top up refrigerant during a service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Topping up without finding the leak means the gas escapes again, so we don’t recommend it.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Air conditioning servicing in Chalfont St Peter
For homes with one or two units and businesses with many, we can set up a maintenance contract. We agree the visits, what each one covers and the price with your quote, so the system is looked after on a regular schedule. Typical jobs include error codes or flashing lights on the indoor unit and humming, rattling or squealing from the system, across ducted systems, air-to-air heat pumps and wall-mounted split systems.
A service around Chalfont St Peter is booked to suit you, and most single systems take an hour or two.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Different systems, different jobs
Refrigerant performance and leak checks
To find tCO2e, multiply the kg of refrigerant by its GWP and divide by 1,000. So 3 kg of R32 is roughly 2.0 tCO2e, and the same amount of R410A is roughly 6.3 tCO2e. We read the charge from the unit’s label and work it out for you.
Maintenance contracts
A contract helps a business keep its servicing and F-gas checks on track and each visit is recorded.
How it works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Because we plan from pictures or a survey, a job in Chalfont St Peter can normally be finished in one visit.
- We book a time that suits you and confirm the price.
- Before any cleaning, the system is run so we can see how it behaves.
- Filters, coils, fans and drains are cleaned and cleared.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- We run the system again and leave you a service record.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Keep pets and children away from the work area
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Reasons to give us a call include:
- A musty or damp smell when the unit starts
- Error codes or flashing lights on the indoor unit
- F-gas leak checks falling due

When something else is needed
We’ll always give you a straight diagnosis, so here’s what air conditioning servicing won’t do:
- A refrigerant leak, which needs finding and repairing, not topping up
- Pipework or drainage that was badly installed in the first place
- Cooling capacity that doesn’t match the space
