Air con installers in Northam
Not sure what you need, or where it would go? Just phone 07833 053749 or use the quote form with photos of the rooms and the outside of the property, and you will hear back from us the same working day about a survey or a fixed-price quote. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes, and we leave the room clean and the controls explained.
Around Northam, older cottages and newer houses can be very different to work on. Thick walls, low ceilings and beams need care with pipe routes, and if the home is listed, consent comes before any work.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

What happens on the day
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a day or more, depending on the number of rooms, the pipe routes and the access. In a place like Northam, parking is rarely an issue, but tell us about gates and access to the back of the property.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- 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.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Let us know if the building has a permit or sign-in process
Getting a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price before any work starts.

Why act early in Northam
Size matters more than brand. Too small, and it runs flat out without catching up; an oversized one cycles on and off and wastes energy. Getting the sizing right at the survey stage avoids both problems. Booking before summer means the work near Northam is done before the hot weather.
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.

What an install looks like in Northam
Northam is within about 2 miles of the coast. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we will tell you if the model you choose has that option. In the mile around Northam’s centre, 2 conservation areas have been designated. Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as Jesus Chapel - St Mary Extra (grade II*). If your property is listed or sits inside a conservation area, expect us to raise planning at the survey and to speak to the planning team at Southampton council, which normally handles Northam where it’s needed. About 35% of homes in the Northam area were built before 1919, according to Valuation Office Agency council tax records. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can.
Southampton Tudor House and Garden (roughly 1.3 miles south-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. If you commute from Bitterne station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed.
Northam is about 1 mile south-east of Southampton, in Southampton. Northam gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we have finished. We cover 40 places across Southampton. Guildford, roughly 42 miles off, has its own page on this site.

Within a short drive, we also cover Regents Park (3 miles west), Maybush (3 miles north-west), Coxford (3 miles north-west) and Lordswood (3 miles north-west).

Questions from Northam
Is the coast a problem for outdoor units in Northam?
It can, as Northam is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Will you come out to Northam?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will skipping a service affect the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
How much is air conditioning for one room?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. The price is fixed before work begins.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.

What owners can safely do
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
There are a few things you can safely do yourself: 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.
What a customer said
“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.”
