Air conditioning installation in Luton

Try passive cooling first

Close blinds on south and west windows during the day, open windows wide at night when it's cooler outside, and use fans to move air. In loft rooms, extra insulation keeps the sun's heat out. If the room still won't drop below about 26°C at night during a heatwave, a split unit is worth pricing.

Which system

A single split has one outdoor and one indoor unit, ideal for a bedroom. A multi-split connects several indoor units to one outdoor unit. Most models also heat, working like an air-to-air heat pump in winter.

Permissions

One outdoor unit on a house is often permitted development if it meets size and position rules. Flats need the freeholder's consent, and rented homes need the landlord's. Some newer estates have covenants on what you can fix to walls.

Choosing an installer

Only an F-Gas certified engineer can install and commission the refrigerant system. Ask for their certificate, a written cooling load for each room, and details of the warranty and servicing.

Ask where condensate will drain and how the pipework will be routed and covered outside.

Keep running costs down

Set the unit to about 24°C, close curtains on sunny windows and only cool rooms you're using. A modern inverter unit uses little power once the room is cool.
