Air conditioning servicing in Merrow
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 service systems in Merrow and across Surrey, for most leading brands. Common call-outs are for no service record for the last year or more and systems that need a 6 or 12-monthly leak check, on wall-mounted split systems, air-to-air heat pumps and VRF systems.
We book services in Merrow at a time that suits you, and most single systems take an hour or two.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

FAQs for Merrow
Do you cover Merrow for air conditioning servicing?
Yes, Merrow is within the area we cover. To start, phone us on 07833 053749 with a few photos.
Do you cover smaller places like Merrow?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Do you top up refrigerant during a service?
Not as a routine part of the service. The refrigerant circuit is sealed, so a system that is short of gas has a leak. Where the checks point to a leak, we explain the options for finding and fixing it.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we are happy to show ours.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
How much time does an air con service need?
The visit takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Any repair found on the day is priced and agreed before it’s done, so phone us on 07833 053749, or email if that’s easier to arrange a time.

Refrigerant performance and leak checks
To find tCO2e, multiply the kg of refrigerant by its GWP and divide by 1,000. As an example, 3 kg of R32 comes to about 2.0 tCO2e, while 3 kg of R410A is about 6.3 tCO2e. We read the charge from the unit’s label and work it out for you.
Wall-mounted, ducted and cassette units
With a ducted system, the unit is hidden above the ceiling. We need access to the unit, its filters and its drain, so let us know where the hatch is.
Looking after it afterwards
Aftercare is straightforward, and it helps at the next service:
- Know your manufacturer’s servicing conditions
- Clean the filters between services, as the manual describes
- Book the service at least once a year
Run the system for a while after the visit and check it feels right. If you notice anything unusual, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will talk it through.
Make sure condensate pipes outside are not crushed, blocked or buried. A pipe that is been knocked or covered can back up into the indoor unit.
Keeping systems in Merrow running
About 66% of households live in detached or semi-detached houses, according to Census 2021 figures. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. On the National Heritage List, around 15 entries fall within 0.5 miles of the middle of Merrow; The Old Cottage (grade II) is one. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.
A service once a year suits most home systems, and some business systems need more.

The process
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Send pictures of the space and the outside wall, and we can plan the work near Merrow.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- The system is run and checked before anything is opened up.
- Filters, coils and the condensate drain are cleaned and cleared.
- Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
- We leave you a record of the service and explain anything we found.
How to prepare
- Keep pets and children away from the work area
- Clear the space around the indoor unit, or where it will go
- Tell us about any building rules, permits or sign-in
Getting a price
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
