How much is an air con service in Andover?

An air conditioning service from DWM starts from £120. Filters and coils are cleaned, the drain cleared and the system's performance checked.

What happens on the visit

Air conditioning works best when it is clean. Over a year the filters clog with dust, the indoor coil collects dirt, and the condensate drain can block, which leads to smells, drips and a system that has to work harder for the same result.

Dexter services wall-mounted air conditioning systems across Andover, including systems he did not fit. He cleans the filters and indoor coil, clears the drain, checks the outdoor unit and tests the system in cooling and heating, then tells you how it is performing.

Dedicated, professional and friendly, Dexter has done many jobs for us and he never disappoints! Fitting our Air-to-Air heat pump was particularly challenging so we were very glad to have such an expert doing the job.

Excellent experience with Dexter servicing our boiler. He arranged to come promptly, carried out a thorough service explaining what he had found. Tidy, friendly and reasonably priced. Have used him twice now for different things and will continue to do so.
