Conservatory air conditioning in Worthing
If your conservatory in Worthing faces south, that is where overheating is worst. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
In Worthing, the indoor unit usually goes on the original house wall inside the conservatory. We cover Worthing as part of West Sussex, roughly 22 miles from Crawley. That includes the BN11 postcode district.

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
A survey in Worthing 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. On a survey in Worthing 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.
