How we handle air conditioning in Southampton
Air conditioning is not only for summer: most modern splits heat too. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning, so a well-chosen unit can be useful in winter as well as summer. For air conditioning in Southampton, you get one team and one number from survey to sign-off.
In Southampton, most installs are one or two bedrooms and a home office, or a living room that catches the afternoon sun. A single split suits one room, and a multi-split runs two to five rooms from one outdoor unit, so there’s less on the outside wall.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What affects the quote in Southampton
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- How easy the units are to reach
- Whether it’s a one-off job or part of a maintenance contract
- How far the pipework has to run, and where
Height, access and the distance between the indoor and outdoor units can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Helping us quote
Good pictures often save a visit. The most useful are:
- Any previous service or F-Gas records
- Your consumer unit or fuse board
- A few photos of the room and the wall the unit is on, or will go on
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

What else we do in Southampton
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat 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, and that takes a day or more, depending on the number of rooms, the pipe routes and the access. Parking and access to the outside wall or roof are the main things to plan for a job in Southampton.
- 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 needed.
- 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.
How to prepare
- Plan for pets to be kept clear during the visit
- Tell us about parking and loading
- Dig out any previous service or F-Gas records

When it’s something else
In fairness, there are a few things this work won’t fix:
- Building damp that has a structural cause
- An installation that needs consent nobody has given yet
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
If in doubt, phone us on 07833 053749 or fill in the contact form and we will say what we think.
What the work covers
- Multi-split systems
- Air-to-air heat pumps
- Wall-mounted split systems
- Ducted systems
- VRF systems
- Ceiling cassettes
When to call us in Southampton
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window can’t close properly and the noisy part of the unit is in the room. With a split system, the compressor lives outside.
Reasons to give us a call include:
- An ageing air conditioning system near the end of its life
- A portable unit with a hose out of the window
- Working from home in a room that gets too warm
Plenty of people near St Denys station split the week between the train and a spare room, and that spare room is often the first to get a unit.

Your questions about air conditioning in Southampton
Does sea air affect air conditioning in Southampton?
It can. Southampton is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do you cover Southampton for air conditioning?
Yes, Southampton is within the area we cover. Just ring us on 07833 053749, or email if that’s easier with a few details.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
How much does air conditioning installation cost?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Long pipe runs, difficult access, a new circuit and premium indoor units push the price up, and commercial systems are priced after a survey.
Can you fit air conditioning in a leasehold flat?
In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls and the lease will say. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
Can air conditioning heat my home as well?
Most of the time, yes: modern splits are normally heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Air conditioning in Southampton: local notes
The coast is only about 2 miles from Southampton. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we’ll tell you if the model you choose has that option. The Cranbury Place Conservation Area lies close to the centre of Southampton, within about a third of a mile. There are 6 conservation areas within a mile of the centre of Southampton. Historic England lists about 22 buildings and structures within half a mile of the centre of Southampton, including The Old Farm House Public 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 cannot go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with the local planning authority (usually Southampton council) where needed. About 53% of homes in Southampton and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and about 55% of households live in flats, according to the last census (2021). 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. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter.
Living close to Saint Mary's? Some older properties in parts like that are protected, and the survey finds out whether yours is.
