System by system
Fans and compressors
The compressor is the heart of the system. Before blaming the compressor, we check the electrics and the refrigerant circuit. If it has failed, we compare the cost of repair with replacement.
Refrigerant leaks
A low refrigerant charge always means a leak. The leak is found and fixed, then the circuit is tested, evacuated and recharged and every step is recorded.
Air conditioning repair in Alton, done properly
A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead and nothing goes ahead without your say-so. The work covers ceiling cassettes, wall-mounted split systems and ducted systems, and people most often call us about a system that needs topping up again and ice on the pipework or the coil.
Around Alton, the faults we hear about most are weak cooling, dripping indoor units and error codes. Plenty of them come down to dirty filters, a blocked drain or a leak.
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.

On site, the work takes anything from an hour or so to a full day, depending on the fault and the parts. Photos of the room and the outside wall help us plan a job in Alton.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- At the property, readings and tests narrow the problem down to its cause.
- You get a plain explanation of the fault and a fixed price for putting it right.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Preparing for the visit
- Have the make and model of any existing unit to hand

Questions from Alton
Who do I call if my air conditioning fails in Alton out of hours?
The emergency line is open around the clock, and Alton is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Can you do air conditioning repair in Alton?
Yes, Alton is within the area we cover. Tell us a little about the job and we will take it from there.
What does an air con repair cost?
A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead. The final cost depends on the fault, the parts and the access.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone, and we’re happy to show ours.
Why is my air conditioning leaking water?
Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and call us on 07833 053749.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Keeping the system healthy
Looking after it is simple, and it makes the next visit easier:
- Turn the system off if it’s dripping water
- Ask for the leak to be found, not just a top-up
- Let any ice thaw before the engineer arrives
After a repair, the basics matter: clean filters every few weeks in heavy use and space around the outdoor unit. An annual service is the best way to catch the next fault before it stops the system.
Keep the outdoor unit clear. Leaves, plants and stored items around it restrict airflow and make the system work harder, and debris can get into the fan.
