Air conditioning repair for homes and businesses in Southsea
We repair air conditioning on all the main brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It doesn’t matter who installed it and the make and model help us prepare. The work covers ceiling cassettes, ducted systems and wall-mounted split systems, and people most often call us about frost on the pipework and a unit that barely blows any air.
Shops, offices and homes in Southsea all use the same basic kit: an indoor unit, an outdoor unit and the pipes between them. The fault can be at either end, or in between, which is why we test before we replace parts.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

When something else is needed
A few issues sit outside what this work can do:
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- A unit whose parts are no longer made (replacement may be the only option)
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is usually the answer)
If you’re not sure, just call 07833 053749 or send an email and we will give you a straight answer before booking.

System by system
Circuit boards and sensors
Testing comes before any part is replaced, so you do not pay for a part that wasn’t the problem. Parts may need ordering, and we tell you if so.
Refrigerant leaks
Topping up without finding the leak only delays the next breakdown, and it releases more refrigerant into the air. We always find and fix the leak first.
Southsea: your questions answered
Do you cover Southsea for air conditioning repair?
Yes. Southsea is one of the places we cover. Just phone us on 07833 053749 or send an email with a few details.
Does sea air affect air conditioning in Southsea?
It can. Southsea is within about 1 mile of the coast, and salt air speeds up corrosion on outdoor units. Corrosion on the outdoor unit is one of the things we check when we diagnose a fault.
Can you come out for an emergency air conditioning repair?
Yes, 24/7. Emergencies include water coming through a ceiling or a critical room overheating, and we’ll advise on what to do straight away. Call 07833 053749.
Can you still repair R410A air conditioning?
Yes. Repairing and recharging existing R410A systems is still legal. As the GB phase-down continues, R410A is getting harder and dearer to buy and we talk through repair against replacement for older systems.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Why is water dripping from my indoor unit?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Turn the system off to stop the water and give us a call.
What a repair looks like in Southsea
The coast is only about 1 mile from Southsea. Coastal outdoor units can suffer from corroded coils and terminals, which can lead to poor cooling or trips. Roughly a third of a mile or less from central Southsea, you reach the Craneswater and Eastern Parade, Southsea Conservation Area. There are 10 conservation areas within a mile of the centre of Southsea. The Kings Theatre, listed at grade II*, is one of roughly 15 protected buildings and structures in the half-mile around Southsea’s centre. That only matters for replacements, where a new outdoor unit on a protected building can need consent. Valuation Office Agency council tax records 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. In a terrace, the route to the back garden decides how the visit is planned.
When cooling fails at a school like Craneswater Junior School, we can time non-urgent repair work around lessons. Shops and offices around Fratton station often cannot wait for cooling to come back, which is what the 24/7 line is for.

What we do, step by step
If the system has to be off for part of the visit, we tell you before work begins so it does not catch you out. In a business, work can often be done one area at a time. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. A visit in Southsea is booked for a time that suits you.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Mention any parking restrictions near the property
- Mention any managing agent or landlord rules we need to follow
- Keep pets and children away from the work area
Getting a price
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
Advice
Why deal with it now?
Refrigerant supply is changing. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy and we weigh that up when we advise you. A dirty or faulty system works harder and costs more to run.
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before work begins.
