Air conditioning for extensions and kitchen-diners in Exmouth
An extension in Exmouth with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
In Exmouth, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Exmouth as part of Devon, roughly 37 miles from Plymouth. Homes in EX8 are all within our coverage.

The survey
On a survey in Exmouth the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
