What owners can safely do
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
How we handle air conditioning repair in Hilsea
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. The work covers multi-split systems, wall-mounted split systems and heat pumps, and the jobs we see most are rattling, buzzing or grinding noises and a system that won’t switch on.
Around Hilsea, most of our repairs are in homes, with some small businesses. We plan the visit from what you tell us about the fault, so a description and a photo of any error code really help.
Warranty periods vary by brand and by product. 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. Whatever the brand, the manufacturer’s terms are explained on your quote.

How it works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes anything from an hour or so to a full day, depending on the fault and the parts. Seeing the property in pictures first helps us plan the trip to Hilsea.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you will hear it from us, with the alternatives.
- 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
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Let and managed properties
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we’ll copy in whoever needs it.
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
What else we do in Hilsea
Questions from Hilsea
Is the coast a problem for outdoor units in Hilsea?
It can. Hilsea 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.
Who do I call if my air conditioning fails in Hilsea out of hours?
Hilsea is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Can you repair an R22 air conditioning system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. A fault that doesn’t involve the refrigerant may still be repairable, depending on parts, but a refrigerant leak usually means replacement. We explain the options and quote for a new system if that’s the answer.
Which brands do you work with?
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.
How long will you be on site?
On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Bigger or more complicated systems take longer, and we will tell you what to expect.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger 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. Any work is priced before it goes ahead.
Looking after it afterwards
Once we have finished, these simple steps help:
- Note any error code, or take a photo of the display
- Leave a tripping breaker off and call us
- Rule out the simple causes first: filter, mode and temperature
After the repair, the system is run and checked in every mode it has. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.
Use the system sensibly. Moderate settings and a closed room mean less strain and the system doesn’t have to work as hard.
Air conditioning repairs in Hilsea: local notes
Hilsea lies within about 1 mile of the sea. Salt air speeds up corrosion on outdoor coils and connections, which is one of the things we check on a repair. Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as Gatcombe House (grade II). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. About 35% of homes in and around Hilsea were built between the wars, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 46% of households in terraced houses. On terraced streets, outdoor units are normally at the back, so tell us how we get to the rear of the property.
For a school like Gatcombe Park Primary School, urgent repairs can be booked right away and bigger work in the holidays. Near Hilsea station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.
