Air conditioning servicing in Stonebridge
Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Whatever is in the air, from dust to pet hair, collects on the filter and coil. Servicing removes it, so the system can move air properly and the drain can do its job. If the problem is iced-up coils or pipework and warning lights on the indoor unit, we can sort it out.
Commercial systems in a London area like Stonebridge may need F-gas leak checks as well as a service, depending on its refrigerant charge. We record the checks and tell you when the next one is due.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Different systems, different jobs
Refrigerant performance and leak checks
The engineer looks at how well the system is moving heat, checking temperatures and pressures against what the system should achieve. If something points to a leak, we tell you and set out the options.
Indoor and outdoor coils
Room air passes over the indoor coil, which takes heat out or puts it in. Cleaning removes the dust that coats the fins and any damage is noted.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- A refrigerant leak, which needs finding and repairing, not topping up
- Poor original installation, such as drains without a proper fall
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
If you’re not sure, just ring us on 07833 053749 or fill in the contact form and we’ll give you a straight answer.

FAQs for Stonebridge
Does my air con in Stonebridge need a yearly service?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Can you do air conditioning servicing in Stonebridge?
Yes. We work across London and the South East from our base in East Grinstead, and Stonebridge is part of that. Get in touch with the details and we reply the same working day.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Do I need a service to keep the manufacturer’s warranty?
The warranty comes from the manufacturer, on its own terms. Read the conditions for your brand, as they may include servicing, and keep each service record with the warranty paperwork.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
How the visit works
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, 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. Some blocks in Stonebridge need contractor details in advance, so tell us what your building needs.
- We start with the details of the system and anything you’ve noticed.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- Anything we find is explained, with a fixed price if it needs a repair.
Before we arrive
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Mention any roof access, ladders or high-level work

Photos are enough for some jobs; others need a visit first. 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.
Advice
Before you call an engineer
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
