Wall-mounted air conditioning in Eltham
In a semi or terrace in Eltham, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
A single wall-mounted unit is often all a bedroom or sunny living room in Eltham needs. Eltham lies roughly 8 miles from central London, and we cover it as part of London. Homes in SE9 are all within our coverage.
