Air con installers in Southsea
Across Southsea, every installation follows the same steps: a site survey, or photos for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. Every installation in Southsea begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
Southsea has a mix of older and newer homes, and the walls decide a lot about the install. Older solid walls need more drilling than modern cavity walls, while a loft space can hide pipe runs that would otherwise be on the outside.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What we do, step by step
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Photos of an existing unit and its label help with repairs and servicing in Southsea.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Getting ready for the visit
- Keep pets and children away from the work area
- Clear a path to the units and the space around them
- Mention any managing agent or landlord rules we need to follow
Getting a price
Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, phone us on 07833 053749 or drop us a line.

Air conditioning in Southsea: the local picture
The coast is only about 1 mile from Southsea. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. The Valuation Office Agency’s council tax figures put about 74% of homes in Southsea and the neighbourhoods around it before 1919, and Census 2021 figures found about 57% of households in terraced houses. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. Terraces have little side access, so the outdoor unit normally goes on the rear wall or a flat roof, with the pipe run kept short.
If you commute from Fratton station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed. Older streets near St Margaret of Scotland may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
Southsea is about 2 miles south of Portsmouth, in Portsmouth. Homes and businesses alike in Southsea, we can help with air conditioning. You’ll hear back from us the same working day, and there’s a 24/7 emergency line. We cover 19 places across Portsmouth, large and small. Our Worthing page covers places nearby (29 miles or so).
Our nearest recent job to Southsea was on East Street, Chichester (PO19), about 13 miles east: installing a Daikin wall-mounted unit in the dining area and a second unit serving the kitchen pass area. See the job
Every address in PO5, PO4 and PO1 is covered, from busy streets to back roads. From Bath Road, Liss Road and Beach Road to the smaller roads in between, nowhere is left out. We also cover the places around Southsea: Milton (1 mile north-east), Fratton (1 mile north), Kingston (1 mile north), Landport (1 mile north-west) and Baffins (2 miles north). Within a short drive, we also cover Hilsea (3 miles north), Wymering (4 miles north), Paulsgrove (5 miles north) and Cosham (4 miles north).
Around Southsea
Around Southsea, our work takes us to homes and businesses near The Festing pub, St Edmund's Catholic School and Mayville High School, among other places. The closest station to Southsea is Fratton station, about 0.8 miles north. A little further out are St. Mary's Hospital (1 mile north) and Southsea Castle (1 mile south-west). For a walk, there’s Milton Locks.
What happens if it’s left?
Planning ahead beats a rushed decision in a heatwave. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. A survey now gives time to choose properly. A dirty or faulty system works harder and costs more to run.
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Why book with us
- 24/7 emergency line for breakdowns
- Clear warranty information from the manufacturer

Your questions about air conditioning in Southsea
Is the coast a problem for outdoor units in Southsea?
It can, as Southsea is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Will air conditioning in Southsea need planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Southsea is a short walk from the Craneswater and Eastern Parade, Southsea Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Portsmouth council, which is usually the planning authority for Southsea.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Do you cover Southsea?
Yes. We work across Greater London, Surrey, Kent, East and West Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Southsea included.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can I have air conditioning in a 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.
How we price air conditioning
The diagnosis comes before the price. The main factors are:
- The equipment or parts the job needs
- One-off work versus a regular service cycle
- How easy the units are to reach
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Asking for a quote
Simple jobs can often be priced from photos and some basics. Useful things to send:
- A photo of the consumer unit with the cover closed
- A short video of any fault, such as a noise or a flashing light
- The outside wall, roof or yard where the outdoor unit sits or would go
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Rented and managed buildings
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
