Air conditioning servicing in Thornton Heath, Greater London
Looking for air conditioning servicing in Thornton Heath? We look at the job first, give you a fixed-price quote and do the work at a time that suits you, finishing with proper records.
- A unit showing a fault code
- Ice forming on the pipework or outdoor unit
- An unpleasant odour when the system runs
Keeping the system healthy
Systems last better with the right care. Here’s what we suggest:
- Leave space around the outdoor unit for air to flow
- Report drips, smells or noises early
- Keep the service records with the warranty paperwork
Where the system needs F-gas leak checks, the result is recorded and the next one falls due within 6 or 12 months, depending on the system. We can book it in ahead of time.
Act on the early signs. A new noise, a faint smell or a drip is easier to deal with early than after a breakdown.
Air conditioning servicing in Thornton Heath
Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Dust, fluff and anything else in the air ends up on those parts. Servicing removes it, so the system can move air properly and the drain can do its job. The work covers air-to-air heat pumps, multi-split systems and ducted systems, and people most often call us about water dripping from the indoor unit and iced-up coils or pipework.
For a flat or office in Thornton Heath, tell us where the outdoor unit is and how we reach it, as that affects how long the service takes. If the building has a managing agent, we can book in with them.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

Fixed-price quotes for air conditioning servicing in Thornton Heath
We quote each job individually. These are the things that affect it:
- Whether we need access equipment for high-level work
- What kind of system it is
- The brand, model and parts involved
The cost depends on the type of system and how many units are involved, the access and what the work involves. You get a fixed price before we start, so you know where you stand.
Asking for a quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- Your installation or service records
- A photo of the consumer unit with the cover closed
- The outdoor side of the property, including any roof or flat area
For air conditioning servicing in Thornton Heath, call us on 07833 053749 or write to us at info@aircondoctor.co.uk. Let us know the type of property and what you need, plus some pictures if they’re to hand. Enquiries get a reply the same working day.
Safe owner checks
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes a short visit for one split system, longer for multi-split, ducted or commercial plant, and we clear up before we go. Send us a few phone pictures and we can often price a straightforward job in Thornton Heath before visiting.
- A date is fixed and the service price confirmed in advance.
- The engineer runs the system and checks how it’s performing.
- Filters, coils, fans and drains are cleaned and cleared.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- A final test run follows, then you get the service record.
How to prepare
- Plan for pets to be kept clear during the visit
- Tell us about parking and loading
- Tell us about access, such as roof hatches, high walls or locked plant areas

Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Your questions about air conditioning servicing in Thornton Heath
Do you cover Thornton Heath for air conditioning servicing?
Yes. Thornton Heath is one of the places we cover. Get in touch with the details and we reply the same working day.
How often should air conditioning in Thornton Heath be serviced?
Normally once a year for homes, more often for busy business systems. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Is an F-gas leak check a legal requirement for my system?
The GOV.UK rules set leak checks at least every 12 months for 5 to under 50 tCO2e and every 6 months for 50 to under 500 tCO2e. With leak detection fitted, the interval can be doubled, and we can tell you where your system sits.
Is there a survey before the work?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
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. Before we leave, we clear up and run through the work with you.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Is a regas part of an air conditioning service?
Not as a routine part of the service. The refrigerant circuit is sealed, so a system that’s short of gas has a leak. We check the refrigerant performance, and if we suspect a leak we explain how it can be found and repaired.
