How the job changes from property to property
Wall-mounted, ducted and cassette units
Cassette units are set into the ceiling and blow air in several directions. We drop the grille to clean the filters and check the condensate pump.
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.
Air conditioning servicing in Richmond upon Thames, done properly
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. Common call-outs are for F-gas leak checks falling due and an unpleasant odour when the system runs, across ducted systems, air-to-air heat pumps and ceiling cassettes.
Commercial systems in a London area like Richmond upon Thames may need F-gas leak checks as well as a service, depending on its refrigerant charge. The check is recorded, with the next date noted.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we are called out for in Richmond upon Thames
Filters clog gradually, a little more every day the system runs. Clogged filters choke the airflow and the unit has to work harder to reach the set temperature.
Keep an eye out for these signs:
- Error codes or flashing lights on the indoor unit
- A musty or damp smell when the unit starts
- A system that struggles to cool on warm days
If you look after a school such as Marshgate Primary School, servicing is easiest in the holidays.

FAQs for Richmond upon Thames
How do I get a quote for air conditioning servicing in Richmond upon Thames?
The easiest way is to call us on 07833 053749 with a few details and pictures. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Is Richmond upon Thames in your area for air conditioning servicing?
Yes, Richmond upon Thames is within the area we cover. Tell us a little about the job and we will take it from there.
Do I need a service to keep the manufacturer’s warranty?
Warranty terms are set by the manufacturer, not by us. Check your brand’s conditions, which may mention servicing, and keep each service record with the warranty paperwork.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Which manufacturers do you install and repair?
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 tell you why.
Who is responsible for 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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
