Air conditioning servicing in Harwell
A service is as much a check-up as a clean. We listen to the fans, look at the pipework and insulation, test the controls and check the electrical connections are sound, and tells you about anything that looks like it’s heading for trouble. We’re often asked to deal with a unit showing a fault code and weaker cooling than last year, on wall-mounted split systems, ducted systems and ceiling cassettes.
Outdoor units around Harwell tend to be close to gardens and hedges, so the outdoor coil can clog with leaves and seeds. Every service includes cleaning it.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

When it’s something else
A few issues sit outside what this work can do:
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
- A refrigerant leak, which needs finding and repairing, not topping up
- Parts that have failed and need replacing
Not sure which it is? You can phone 07833 053749 or fill in the contact form and we will tell you honestly before booking.
What the work covers
- Ceiling cassettes
- Air-to-air heat pumps
- Ducted systems
- Multi-split systems
- Wall-mounted split systems
- VRF systems
Leave it or put it right?
If your system needs F-gas leak checks, they aren’t optional. Missing one leaves you without the check and the record, and it’s simpler to keep to the schedule. Dealing with it now is normally simpler than a breakdown later.
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

Servicing in Harwell: local notes
The Harwell Conservation Area is within about a third of a mile of the centre of Harwell. Listed buildings are part of the picture here: about 66 within half a mile of the centre, such as Church of St Matthew (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. VOA council tax data show about 42% of homes in the Harwell area were built in 2000 or later, and about 70% of households live in detached or semi-detached houses, according to the last census (2021). Tell us where your outdoor unit is and how to reach it, so we can plan the visit.
Booking before the first hot spell means the system is ready when you need it. Site managers at schools like Harwell Primary School can have the site’s units serviced during a holiday.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. The work takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Photos of the room and the outside wall help us plan a job near Harwell.
- A date is fixed and the service price confirmed in advance.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- It’s run once more to confirm all is well, and the record is left with you.
Before we arrive
- Mention any parking restrictions near the property
- Make sure we can reach the consumer unit or fuse board
- Keep pets out of the rooms we’re working in

Advice
Harwell: your questions answered
Do you cover Harwell for air conditioning servicing?
We do: Harwell falls inside our working area. Tell us a little about the job and we will take it from there.
Will you come out to Harwell?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are members of Checkatrade too.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
How often should air conditioning be serviced?
Yearly servicing is the usual starting point, with more visits for systems that run a lot. The manufacturer’s warranty terms may say something about servicing, so it’s worth reading them.
Is an F-gas leak check a legal requirement for my system?
Only if the system is at or above the threshold of 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Do you protect the property while you 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 have done.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
