Your questions about air conditioning servicing in Dedworth
How often should air conditioning in Dedworth be serviced?
Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Is Dedworth within the area you cover?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you have a 24/7 line?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
How quickly will you reply?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
About our air conditioning servicing in Dedworth
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We service systems in Dedworth and across Windsor and Maidenhead, for most leading brands. Common call-outs are for frost or ice on the refrigerant pipes and leak check records that need bringing up to date, on VRF systems, ceiling cassettes and wall-mounted split systems.
In a place like Dedworth, the outdoor unit often sits near a garden, hedge or trees, which can clog the outdoor coil. Every service includes cleaning it.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

How the job changes from property to property
Filters
The filter is the first line of defence for the indoor unit. We clean them and check for damage, and if a filter is past its best we tell you.
Condensate drains and pumps
Cooling pulls moisture out of the air, and that water has to drain away. The tray is cleaned and the pipe flushed through so it flows properly.
Signs you need air conditioning servicing in Dedworth
Electrical terminals can work loose as the system heats, cools and vibrates. A loose connection can cause faults that come and go, so the engineer checks them as part of the service.
Common reasons people call us include:
- No service record for the last year or more
- Warning lights on the indoor unit
- Frost or ice on the refrigerant pipes
Site managers at schools like Dedworth Green First School can have the site’s units serviced during a holiday.

Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts.

- We start with the details of the system and anything you’ve noticed.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- If a repair is needed, you hear why and what it costs before anything is done.

Keeping the system healthy
Looking after the system is mostly common sense. A few tips:
- Clear leaves and debris from around the outdoor unit
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Keep to an annual service, or more often if needed
Once we have gone, use the system as normal and see how it performs. If anything seems off, ring 07833 053749 and we’ll talk it through.
Book a service at least once a year with extra visits where the system runs constantly or needs more frequent leak checks.
