A job we did in KT12
Walton-on-Thames KT12
Samsung air source heat pump
Sited round the corner from the conservatory glazing rather than beside it, because a fan discharging at glass is the most common cause of a noise complaint about a unit that is running perfectly.
What the housing in Walton-on-Thames means for the job
KT12 is Walton, Hersham and the riverside, and the housing is mostly interwar and post-war detached and semi-detached with substantial gardens. Outdoor positions are rarely a constraint and pipe runs are short. What is distinctive here is the number of conservatories, garden rooms and glazed rear extensions, which are the rooms people actually want cooled and also the hardest rooms to cool, because glass gains heat far faster than brick. The riverside properties add a flood-zone consideration that is worth raising at the survey rather than after.
Worth knowing before you book. A fan discharging at a conservatory or a glazed extension is the single most common cause of a noise complaint about a machine that is running perfectly. Moving it two metres round a corner at the survey costs nothing and solves it permanently.

Air conditioning in Walton-on-Thames: common questions
Can you cool a conservatory?
Yes, and it needs more output than the floor area suggests because glass gains heat at several times the rate of a wall. The honest answer is that a conservatory with single-skin polycarbonate above it will always be fighting.
Will the neighbours hear it?
A modern unit at low fan speed is quieter than a fridge at a couple of metres. What makes one audible is reflection: a fan pointed at glass, a fence or a flank wall a metre away.
Why a unit sounds louder than it is, and what to do about it.
Is KT12 inside your area?
Yes. Elmbridge is normal work for us and the photograph on this page is a Walton installation.
