Air conditioning servicing in Colindale, done properly
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 carry out air conditioning servicing for homes and businesses in Colindale and the rest of Greater London, whatever the make. The work covers VRF systems, multi-split systems and ceiling cassettes, and people most often call us about a service that’s overdue and condensate leaking into the room.
Commercial systems in a London area like Colindale may need F-gas leak checks as well as a service, depending on how much refrigerant it holds. The check is recorded, with the next date noted.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Keeping systems in Colindale running
In the mile around Colindale’s centre, 2 conservation areas have been designated. About 8 listed entries lie within half a mile of central Colindale. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. The Valuation Office Agency’s council tax figures show about 50% of homes across Colindale and its surrounding area were built in 2000 or later, and the last census (2021) found about 67% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we’ll need to get to the outdoor unit. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service.
Site managers at schools like Colindale Primary School can have the site’s units serviced during a holiday. Spring is a good time for a service, before the system is needed for cooling.

Colindale questions
How often should air conditioning in Colindale 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.
What’s the best way to get a price for air conditioning servicing in Colindale?
Send us pictures of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s 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.
Does my air conditioning need an F-gas leak check?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.
What does an air con service involve?
Filters, coils, fans and the condensate drain are all cleaned and checked. We also check the electrical connections, the controls and the refrigerant performance plus a leak check on systems that need one.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
For landlords and property managers
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. A few pictures of the room, the outside wall and the fuse board help us plan a job in Colindale.

Condensate drains and pumps
Drain trays can collect sludge. Cleaning them helps with drips and with musty smells.
Refrigerant performance and leak checks
F-gas leak checks are required for systems from 5 tCO2e upwards: at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e doesn’t need them.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
