Air conditioning installation in Longmoor
Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. For air conditioning in Longmoor, you get one team and one number from survey to sign-off, wherever you are in Hampshire.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Villages like Longmoor often have older houses and cottages, some of them listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building, and the outdoor unit position is chosen to suit the building.
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’re happy to talk you through them.

Air conditioning around Longmoor
About 71% of households live in detached or semi-detached houses, according to the 2021 Census. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it. At about 45 miles from central London, Longmoor sits inside the area we cover across London and the South East.
Modern air conditioning can heat as well as cool, which suits rooms the main heating does not reach. Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.
Longmoor is about 3 miles south of Bordon, in Hampshire. Across the GU33 area, our engineers can take on air conditioning. We cover 683 places across Hampshire, large and small. For properties nearby, see our Guildford page (18 miles or so).
Our nearest recent job to Longmoor was on Petworth Road, Haslemere (GU27), about 7 miles east: installing a Mitsubishi Electric multi-split system serving the master bedroom, two further bedrooms and the basement games room. More about it
Work in GU33 follows the same survey, fixed-price quote and written records as everywhere else we cover. You will find streets such as Woolmer Road, Roberts Road and Methuen Road, each of them within reach. We also cover the places around Longmoor: Greatham (1 mile west), Woolmer (1 mile north-west), Liss Forest (2 miles south-west), The Mint (2 miles south) and Blackmoor (2 miles north-west). Further out, we also cover Havant (15 miles south), Fleet (14 miles north), Horndean (13 miles south-west) and Aldershot (13 miles north).

Managing agents and facilities teams in Longmoor
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Longmoor questions
Is Longmoor in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Longmoor is part of that. To start, give us a ring on 07833 053749 or send an email with a few photos.
How do I get a quote for air conditioning in Longmoor?
Use the quote form, or email, with a description of the job. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking and we’ll gladly show you ours.
Do I need to service the system to keep the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
Do I need a new electrical circuit?
Most of the time. The fuse board is checked on the survey, and any electrical work goes on the quote, and our NICEIC approval covers the installation and certificate.

What happens on the day
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. Work in Longmoor is booked in advance at a time that suits you.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any managing agent or landlord rules we need to follow
Ask for a quote
Here’s what helps us quote: where the property is and what kind of building it is, a few pictures, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, phone 07833 053749 or use the quote form.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Work that needs permission from a landlord or the council
- Stuffy rooms that need fresh air rather than cooling
If in doubt, call us on 07833 053749 or send an email and we will say what we think.

What you can do yourself, and what needs 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 electrics need care too. Ask us to quote for a move instead.
There are a few things you can safely do yourself: 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.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
