When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what air conditioning servicing will not do:
- Installation faults that need reworking
- Rooms that gain heat faster than any unit could cope with
- A refrigerant leak, which needs finding and repairing, not topping up

Air conditioning servicing in Patchetts Green
A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. The terms differ from brand to brand, so it’s worth reading yours, and we can explain what yours says. Our service record shows the work was done. Common call-outs are for an unpleasant odour when the system runs and new noises from the indoor or outdoor unit, across wall-mounted split systems, air-to-air heat pumps and ceiling cassettes.
Around Patchetts Green, outdoor units sit close to gardens and greenery, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
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.

What a service looks like in Patchetts Green
About 16 miles out from central London, Patchetts Green is part of the South East area we work across. The Patchetts Green and Delrow Conservation Area is within about a third of a mile of the centre of Patchetts Green. Draw a one-mile circle round the middle of Patchetts Green and it takes in 4 conservation areas. On the National Heritage List, around 15 entries fall within 0.5 miles of the middle of Patchetts Green; Church of St John the Baptist (grade I) is one. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
Schools such as Queens' School can book servicing for half term or the summer break, when rooms are empty. If you cannot remember the last service, it’s probably due.

Leave it or put it right?
Smells from an indoor unit tend to come back each time it runs. The cure is cleaning where the dirt has built up, rather than masking it. Dealing with it now is typically simpler than a breakdown later.
The cost depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before work begins, so you know where you stand.

What else we do in Patchetts Green
Patchetts Green questions
Does my air con in Patchetts Green need a yearly service?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Will you come out to Patchetts Green?
Yes. Patchetts Green is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
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.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Managing agents and facilities teams in Patchetts Green
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side, and the paperwork can go to both.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
The process
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, check the system and explain it all to you. On site, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. A few photos help us make the most of a visit to Patchetts Green.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- On arrival, a quick performance check shows how well it’s working before the clean.
- We clean the filters and coils and make sure the condensate drains away.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
Preparing for the visit
- Keep pets and children away from the work area
- Find the manual or the paperwork for the system, if you have it
- Tell us about any building rules, permits or sign-in
Ask for a quote
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
Advice
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
