Air conditioning servicing in Garston, done properly
Maintenance contracts suit anyone who would rather not have to remember when the next service is due. We agree the visits, what each one covers and the price with your quote, and the servicing happens on schedule. The work covers air-to-air heat pumps, ceiling cassettes and wall-mounted split systems, and common reasons people get in touch are an unpleasant odour when the system runs and a system that struggles to cool on warm days.
In a place like Garston, the outdoor unit often sits near a garden, hedge or trees, which can clog the outdoor coil. Every service includes cleaning it.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Air conditioning servicing in Garston: the local picture

Tell us where your outdoor unit is and how to reach it, so we can plan the visit.

System by system
Indoor and outdoor coils
Coil fins are thin and easily flattened. We note any damage and tell you if it’s affecting performance.
Condensate drains and pumps
Some indoor units rely on a small pump to move the water. The pump is tested to make sure it works, because a failed pump is a common reason for drips.
The process
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit, and we clear up before we go. Photos of the existing unit and its label help with repairs and servicing near Garston.
- First, we agree a time and confirm the cost of the service.
- Before any cleaning, the system is run so we can see how it behaves.
- Then the cleaning: filters, coils, fan and the drain line.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- It’s run once more to confirm all is well, and the record is left with you.
Preparing for the visit
- Let us know where we can park and unload
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Keep pets and children away from the work area
How to get a quote

Garston questions
Is Garston in your area for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Garston is part of that. Tell us a little about the job and we’ll take it from there.

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’re members of Checkatrade too.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
Does the manufacturer’s warranty require regular servicing?
The warranty comes from the manufacturer, on its own terms. Read the conditions for your brand, as they may include servicing and file every service record.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Signs you need air conditioning servicing in Garston
Electrical terminals can work loose as the system heats, cools and vibrates. A loose connection can cause faults that come and go which is why they’re checked on every service.
These are the situations we see most often:
- Air conditioning that is not cooling as well as it did
- A unit showing a fault code
- Drips or damp patches below an indoor unit
Businesses close to Garston station can book an early or late slot so the service does not get in the way of trade.
Questions to ask before you book
- How VAT is shown, and which rate applies
- What happens if the job turns out to be different on the day
- What paperwork you’ll receive afterwards
