Wall-mounted air conditioning in Southall
Where a home in Southall faces the street, the outdoor unit usually goes at the rear, out of sight. 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.
A single wall-mounted unit is often all a bedroom or sunny living room in Southall needs. We cover Southall as part of London, roughly 11 miles from central London. We cover UB1 and the streets around them.
