Air conditioning for homes and businesses in Letchworth Garden City
Not sure what you need, or where it would go? Just give us a ring on 07833 053749, or email if that’s easier with pictures of the rooms and the outside of the property, and we will reply the same working day to arrange a survey or a quote. Most split systems we fit in Letchworth Garden City are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
Letchworth Garden City has a mix of older and newer homes, and that changes how the pipework goes in. Solid walls take longer to core drill than cavity walls, while a loft space can hide pipe runs that would otherwise be on the outside.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Letchworth Garden City: your questions answered
Is planning permission needed for air conditioning in Letchworth Garden City?
There’s no single answer: the building and the outdoor unit position decide it. The Letchworth Conservation Area takes in the middle of Letchworth Garden City. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at North Hertfordshire council, normally the authority for Letchworth Garden City.
Can you do air conditioning in Letchworth Garden City?
Yes. We work across London and the South East from our base in East Grinstead, and Letchworth Garden City is part of that. To start, call 07833 053749 or email us with a few photos.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Where does the outdoor unit go?
We agree it with you on the survey. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We’ll tell you what to check before we fit it.
Should I choose wall-mounted, ducted or cassette?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling, which we check on the survey.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
How the visit works
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. In a town like Letchworth Garden City, parking is usually straightforward, so the main questions are access and timing.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any roof access, ladders or high-level work
- Unlock any gate, garage or side passage we need
Getting a price
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

What else we do in Letchworth Garden City
Owner checks or an engineer?
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
Different systems, different jobs
Multi-split systems
Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, depending on the property and the pipe route. It needs airflow around it and room for servicing.
Air conditioning in Letchworth Garden City: local notes
About 30% of homes in the Letchworth Garden City area were built between the wars, according to the Valuation Office Agency’s council tax figures. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route.
With historic houses such as Hinxworth Place about 4.6 miles north, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Homes near St Michael are a good example of where we look up the heritage status of the building before fixing anything to it.

How we price air conditioning
A fixed price needs a few facts first. We check:
- The electrical supply and whether a new circuit is needed
- How easy the units are to reach
- The number of rooms, units or zones
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before work begins.
