Why people choose us

Air conditioning that suits the room, the house and the bills

Most problems with air conditioning come from guesswork: the wrong size, the wrong position or a rushed install. We start with a survey and design from there.

Sized room by room

We measure glazing, orientation and use, so the unit suits the room and runs quietly.

Neat, tidy installation

One clean wall hole per unit, pipework in slim trunking or hidden, dust sheets down.

Heats as well as cools

Modern split systems are heat pumps, so the same system keeps you warm in winter.

Looked after afterwards

Annual servicing, deep cleans and repairs when you need them, for systems we fit and most we did not.

Shop by system

Every service, grouped by what you need

Guide prices include VAT and assume a standard installation. Your survey turns them into a fixed price.

FAQ

Questions we get asked

How much does air conditioning cost to install?

A single-room wall-mounted system typically costs £1,150–£2,450 fitted including VAT in 2026, a 2–4 room multi-split £2,450–£6,950, and ducted systems £5,450–£12,950. Prices vary by region and installation. Our survey and written quote are free.

Is the survey really free?

For new installations on the UK mainland, yes: the survey and written quote cost nothing and you are under no obligation. Surveys on islands not joined by a bridge and in remote parts of the Highlands and Argyll are by arrangement, with any travel cost quoted first. Repair and service visits are charged at a price agreed before we visit.

How quickly can you install?

Lead times depend on the season and the job. We give you an installation date with your quote. Spring is usually the easiest time to book before summer.

Do you fit in my area?

We cover England, Scotland, Wales and Northern Ireland. Enter your postcode in the quote tool or call us and we confirm coverage and a survey date.

Who carries out the work?

Installations are carried out by F-gas certified engineers working for us. Your contract is with S&K Property Investments and Improvement Ltd, which trades as Aircon Installers. Your quote names who will do the work and the F-gas company certificate that covers it.

Does air conditioning heat as well?

Yes. Almost every split system sold today is a reversible heat pump that heats efficiently in winter.

Do I need planning permission?

Most houses in England and Wales can have an outdoor unit under permitted development if size, number and noise conditions are met. Flats, listed buildings and some homes in conservation areas need permission or consent. We check on survey.

Is there a grant?

Air-to-air heat pumps installed by an MCS-certified installer can qualify for a £2,500 Boiler Upgrade Scheme grant in eligible homes in England and Wales, as long as no gas, oil or LPG boiler stays in use. We check eligibility with you.
