We cover Portsmouth for air conditioning repair. A look at the job first, a fixed-price quote and written records at the end.
- A unit blowing warm air
- A suspected refrigerant leak
- Rattling, buzzing or grinding noises
How it works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Town-centre streets in a place like Portsmouth can be tight, so tell us the parking options.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- At the property, readings and tests narrow the problem down to its cause.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Tell us about parking and loading
- Tell us about any building rules, permits or sign-in

Air conditioning repair around Portsmouth
The coast is only about 1 mile from Portsmouth. Salt air speeds up corrosion on outdoor coils and connections, which is one of the things we check on a repair. Portsmouth’s centre is no more than about a third of a mile from the St Mary's Churchyard, Fratton Conservation Area. Draw a one-mile circle round the middle of Portsmouth and it takes in 2 conservation areas. Historic England lists about 20 buildings and structures within half a mile of the centre of Portsmouth, including Church of St Mary (grade II*). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 57% of homes across Portsmouth and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 53% of households live in terraced houses, according to Census 2021 figures. Terraced homes rarely have side access, so say whether we reach the back through the house, a garage or a rear lane.
Schools such as Manor Infant School can report a fault on the 24/7 line and have non-urgent work done out of term. If your system near Fratton station stops in a hot spell, our 24/7 line is open.

What else we do in Portsmouth
Aftercare tips
A little care keeps the system in better shape. Our advice:
- Leave a tripping breaker off and call us
- Keep the outdoor unit clear of leaves and clutter
- Only let an F-Gas qualified engineer work on the refrigerant
If a repair doesn’t make sense, you’ll hear it from us, with the reasons. If replacement is the better option, we can quote for it on the same visit.
Don’t ignore early signs. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault and catching it early keeps the repair simpler.
What air conditioning repair cannot fix
Some problems need a different service or another trade:
- A unit whose parts are no longer made (replacement may be the only option)
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- An R22 system that has lost its refrigerant
Not sure which it is? You can ring 07833 053749 or email us and we will tell you honestly.
Parts of the system we cover

Questions from Portsmouth
Is there an emergency air con repair line for Portsmouth?
Portsmouth is within our area, and the emergency line is open 24/7. Have the make, model and error code ready, and we will talk you through what happens next.
Does sea air affect air conditioning 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. We look for corroded coils, fixings and connections on coastal repairs.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
Why is my air conditioning showing a fault code?
The code is the system’s own clue to the fault, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and call 07833 053749, or email if that’s easier.
What causes water to leak from an air conditioning unit?
Most of the time, it’s the condensate system: a blockage, a kink or a pump that has stopped. Turn the system off to stop the water and give us a call.
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.”
