Air conditioning for extensions and kitchen-diners in Rhondda
Humid summer spells in South Wales make dehumidifying and cooling equally welcome. For a kitchen-diner in Rhondda, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Rhondda with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Rhondda sits around 12 miles from Bridgend, inside our Mid Glamorgan area. Homes in CF42 are all within our coverage.

Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
