Bedroom and loft air conditioning in Coulsdon
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. Loft conversions and top-floor bedrooms in Coulsdon gain heat through the roof all day and give it back at night.
For bedrooms in Coulsdon, we place the outdoor unit at the back of the house, away from neighbours' windows. Coulsdon sits around 12 miles from central London, inside our London area. We cover CR5 and the streets around them.

Planning and permissions
For most houses in Coulsdon, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. On a survey in Coulsdon 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.
