Questions from Portsmouth
Is the coast a problem for outdoor units in Portsmouth?
It can, as Portsmouth is within about 1 mile 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.
Is air conditioning in Portsmouth permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The St Mary's Churchyard, Fratton Conservation Area is close to the centre of Portsmouth. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Portsmouth, normally Portsmouth council).
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can the outdoor unit go on a roof or at ground level?
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. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
How much is air conditioning for one room?
A single-room split system is typically £1,200–£2,200 + VAT. A two-room multi-split is 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.
Air conditioning in Portsmouth, done properly
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. A lot of the calls we get from Portsmouth are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Many installs in Portsmouth can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we tell you at the survey if it applies.
In Portsmouth, a flat above the shops and a semi on the edge of town are very different installs. Flats bring leases, freeholders and limited outside space, while houses typically have a side or rear wall that suits the outdoor unit.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Common problems we fix in Portsmouth
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, which is why a loft bedroom can still be warm at bedtime.
Most people get in touch after spotting something like this:
- An old system that needs replacing
- Portable units that are noisy and barely cope
- An office, shop or restaurant that’s uncomfortable for staff and customers
Plenty of people near Fratton station split the week between the train and a spare room, and that spare room is often the first to get a unit.

Air conditioning in Portsmouth: local notes
Portsmouth is within about 1 mile of the coast. That is worth knowing for an install, as salt air speeds up corrosion on outdoor coils and fixings, so we choose the position and fixings with that in mind. The Valuation Office Agency’s council tax figures put about 57% of homes in the Portsmouth area before 1919, and about 53% of households live in terraced houses, according to the 2021 Census. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit.
Around St Wilfrid, a quick check of the listing and conservation maps is part of planning any install.

What else we do in Portsmouth
What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring us on 07833 053749 or fill in the contact form.
The process
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Larger jobs in Portsmouth can be done in stages, so part of the building stays in use.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Tell us about parking and loading
- Let us know if the building has a permit or sign-in process
- Mention any roof access, ladders or high-level work

Advice
Looking after it afterwards
A little care keeps the system in better shape. We recommend:
- Close windows and doors while the system is cooling
- Have the system serviced once a year
- Let filters dry fully before you put them back
Commissioning is the last stage: every mode is tested before we go. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.
A customer’s words
“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.”
