Air conditioning for extensions and kitchen-diners in Ashford, Surrey
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. In Ashford, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Ashford, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Ashford, Surrey sits around 9 miles from Woking, inside our Surrey area. We cover TW15 and the streets around them.
