Air conditioning for extensions and kitchen-diners in Waterlooville
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. For a kitchen-diner in Waterlooville, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Waterlooville with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Waterlooville as part of Hampshire, roughly 16 miles from Southampton. Homes in PO7 are all within our coverage.
