Bedroom and loft air conditioning in St Austell
Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks. Top-floor flats in St Austell feel the heat most, because the roof sits right above the bedroom.
Loft conversions and top-floor bedrooms in St Austell gain heat through the roof all day and give it back at night. St Austell lies roughly 13 miles from Truro, and we cover it as part of Cornwall. We cover PL25 and the streets around them.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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 St Austell 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.
