Air conditioning for extensions and kitchen-diners in Archway
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. For a kitchen-diner in Archway, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Archway, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Archway lies roughly 5 miles from central London, and we cover it as part of London. Coverage includes N19.

Planning and permissions
For most houses in Archway, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
A survey in Archway usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
