Wall-mounted air conditioning in Warminster
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 a semi or terrace in Warminster, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below.
Where a home in Warminster faces the street, the outdoor unit usually goes at the rear, out of sight. Our Wiltshire coverage takes in Warminster, about 30 miles from Swindon. Coverage includes BA12.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
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. On a survey in Warminster 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.
