Different systems, different jobs
Condensate drains and pumps
The condensate drain is behind most indoor unit leaks. Drains block with dirt and growth, pipes get kinked and pumps fail, and a unit that isn’t level can spill water too.
Multi-split systems
With several pipe runs, finding a leak on a multi-split takes method. Each run is checked, then repair, pressure test and recharge.
Air conditioning repair in Sutton Common
Age alone doesn’t decide whether a repair is worth it. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. If you’re dealing with a suspected refrigerant leak and weak airflow from the indoor unit, we can help.
In a London area like Sutton Common, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Looking after your system
Simple habits make a real difference. We recommend:
- Check the settings and the remote’s batteries first
- Leave a tripping breaker off and call us
- Keep to the service interval the manufacturer recommends
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. We do not promise dates we cannot control, so we keep you posted.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips, so keep them clean as the manual describes.

Terraced homes rarely have side access, so say whether we reach the back through the house, a garage or a rear lane.

Sutton Common: your questions answered
How do I get a quote for air conditioning repair in Sutton Common?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Who do I call if my air conditioning fails in Sutton Common out of hours?
Sutton Common is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Why does my air conditioning run but not cool?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, then phone 07833 053749, or email if that’s easier if it’s still not cooling.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
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.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
