Reading's mix of Victorian terraces in Caversham, new-build flats around the station and Green Park, and office blocks along the Basingstoke Road all throw up different air conditioning jobs. A split system that suits a loft conversion in Tilehurst won't be right for an open-plan office in Winnersh, and older properties often need extra thought around wall thickness and where to run pipework without ruining a period cornice. Reading's warm summers and its mix of housing stock mean demand tends to spike from late spring, so booking ahead of a heatwave rather than during one tends to get you a better job and a calmer engineer.
The businesses featured here are drawn from public business listings and ranked using public review rating and review count, with a small lift given to those showing a working website and phone number. We read each business's homepage to check that air conditioning work, whether installation, servicing or repair, is what they primarily do, which keeps plumbers or general electricians who only dabble in it off this page. Listings flagged as permanently closed are stripped out automatically. Where you spot a Trust Verified badge, that business has gone through our fuller check covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information (our How We Verify page has the full detail). Businesses without that badge haven't been through that process with us, so it's worth doing your own checks before you book.
When you're getting quotes, ask what refrigerant the unit uses, whether the price includes the outdoor condenser bracket and any scaffolding or access equipment, and how long the warranty on parts and labour runs. Get confirmation in writing of the room size or square metres they've measured for, since undersized units run constantly and cost more to operate. It's sensible to get two or three quotes for anything beyond a single small split unit, both to compare price and to see who actually turns up and measures the room properly rather than guessing over the phone. Ask to see photos of previous installs nearby, in Reading itself if possible, and check they're happy to leave a benefits leaflet or handover pack explaining how to use and maintain the system.
How We Select & Rate The Best Air Conditioning Pros in Reading
Rankings are driven by review rating and review count pulled from public business listings, with a small lift for businesses that have a working website and phone number. We check each business's homepage to confirm air conditioning work is genuinely their main trade, not a sideline. Listings marked permanently closed are removed automatically. Businesses showing a Trust Verified badge have gone further and passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the complete list. Other businesses on this page haven't been through that process with us, and their inclusion here isn't an endorsement. Always do your own checks before hiring anyone.
Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

How much does an air conditioning pro cost in Reading?
A single-room split system typically runs from around £900 to £1,800 fitted, depending on the make, room size and how far the pipework has to travel to the outdoor unit. Multi-room or multi-split systems for a larger house or small office can climb to £3,000 to £6,000. Annual servicing is usually £60 to £120 per unit. Prices vary with access difficulty, whether scaffolding's needed, and how far you are from the engineer's base, so get two or three quotes before committing.
Do I need planning permission to fit air conditioning in Reading?
Most domestic split systems don't need planning permission, but if you're in a conservation area, which covers parts of Caversham and central Reading, or your property is listed, you should check with Reading Borough Council first. Flats and leasehold properties often need freeholder or management company sign-off too, so check your lease before booking anyone.
What size air conditioning unit do I need for my room?
It depends on room size in square metres, ceiling height, how many windows face the sun, and how many people typically use the room. A rough guide is around 100 watts of cooling capacity per square metre for a well-insulated room, but a decent installer should measure the room themselves rather than quote off a phone call. Undersizing is the most common mistake and leads to a unit running flat out without ever cooling properly.
How long does it take to install air conditioning?
A single split unit in a straightforward room usually takes half a day to a full day. Multi-room systems, or jobs needing longer pipe runs through cavity walls or up through a loft, can take two to three days. Older properties in areas like Caversham or Earley sometimes take longer if the walls are solid brick and need careful drilling to avoid damaging the outside brickwork or render.
Does air conditioning need an F-Gas certified engineer?
Yes. Anyone handling refrigerants during installation, service or removal must hold an F-Gas qualification, it's a legal requirement, not optional. Ask to see the engineer's F-Gas certificate before work starts, and check it covers the size and type of system you're having fitted.
How do I choose between air conditioning pros in Reading?
Ask to see their F-Gas certification and public liability insurance directly, don't just take a website's word for it. Check recent reviews mention air conditioning specifically rather than general plumbing or electrical work, and ask for photos or addresses of nearby jobs if they're willing to share them. Get a written quote that states the unit make, model, capacity and warranty length, and get at least two or three quotes so you can compare like for like rather than just the bottom line figure.
