FAQs for South Merstham
Is South Merstham within the area you cover?
Yes. South Merstham is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
How often do you service systems in South Merstham?
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.
How long will the engineer be here for the service?
As a guide, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Ducted units in ceiling voids and outdoor units in awkward places can add time and we’ll let you know before the visit.
Will you make a mess?
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.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can I have a maintenance contract for my air conditioning?
We do, for one unit at home or many across a site. The visits, what each covers and the price are agreed with your quote and the servicing happens on time.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Air conditioning servicing in South Merstham
A service is not the same as a regas. 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. Typical jobs include no service record for the last year or more and systems that need a 6 or 12-monthly leak check, across air-to-air heat pumps, VRF systems and multi-split systems.
For most homes near South Merstham, a service once a year keeps the system efficient and the filters clean, and some manufacturers’ warranty terms ask for regular servicing.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

- The size of the job
- Whether it’s a simple split or a larger system
- The pipe route between the units
What you pay depends on the system and the number of rooms or units, the access and the parts and time the job needs. You get a fixed price before any work starts, so there are no surprises.

When you call or email, these details help:
- Photos showing the indoor unit and the space around it
- The remote or wall controller showing any error
- The fuse board and where it is in the property
