About our air conditioning in Longford
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. Most enquiries from Longford start with one hot room: a bedroom, a home office or a loft conversion. That is normally a single wall-mounted split, from £1,200 + VAT.
Around Longford, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Safe owner checks
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749.
For landlords and property managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Facilities teams in offices, schools and public buildings book us too in Longford and across Slough. Work can be phased by floor, zone or building around the people who use them.
Homes in Longford and air conditioning
At about 17 miles from central London, Longford sits inside the area we cover across London and the South East. Longford’s centre is no more than about a third of a mile from the Longford Village Conservation Area. There are 2 conservation areas within a mile of the centre of Longford. Historic England lists about 12 buildings and structures within half a mile of the centre of Longford, including Weekly House (grade II). That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with the planning team at Hillingdon council, which usually handles Longford where necessary.
Plenty of people near Heathrow Terminal 5 Rail station split the week between the train and a spare room, and that spare room is often the first to get a unit. Around Church of St Mary, a quick check of the listing and conservation maps is part of planning any install.

Leave it or put it right?
The best time to plan air conditioning is before the hot weather, not during it. A rushed choice is often the wrong size or in the wrong place, which is costly to undo. Booking the survey early gives you time to weigh up the options. A system that is left with a fault, or without a service, typically costs more to run.
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will explain each part.

How it works
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes anything from a day for one room to several days for a multi-room or ducted system. Seeing the property in pictures first means the trip to Longford can be planned properly.
- First comes a site survey, or photos and measurements for a straightforward job.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Have the make and model of any existing unit to hand
- Mention any parking restrictions near the property
- Clear access to the fuse board

Related advice
Longford: your questions answered
Do you cover Longford for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Longford is part of that. Just call us on 07833 053749 with a few details.
Do you cover smaller places like Longford?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Where will you put the outdoor unit?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours, and the position can affect planning.
Will I need planning permission?
Not necessarily. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it typically comes up and the survey picks it up. This is general information, not legal advice.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
