- A unit blowing warm air
What we’re called out for in Thursley
Ice on the pipework or the indoor coil is a symptom, not the fault. Low airflow from blocked filters or a failing fan, or low refrigerant from a leak, are the common causes. Switch the system off and let it thaw before calling us.
Keep an eye out for these signs:
- A system that runs but does not cool the room
- Water leaking from the unit or through the ceiling
- Weak airflow from the indoor unit
Before you call, note what the unit is doing and any code on the controller.
Questions to ask before you book
- Whether you get F-Gas records where refrigerant is involved
- Whether the manufacturer’s warranty depends on regular servicing
- Whether testing, commissioning and paperwork are included
Air conditioning repair for homes and businesses in Thursley
Think of it as a doctor’s appointment for your air conditioning: diagnose the cause, treat it properly and sign it off when it’s working. Guesswork costs money, and replacing a board when the fault is a sensor leaves the problem in place. If the problem is an error code or flashing light on the unit and a unit that barely blows any air, we can sort it out.
We plan the trip to Thursley so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Your questions about air conditioning repair in Thursley
Is Thursley within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Who do I call if my air conditioning fails in Thursley out of hours?
Yes: ring the emergency line, day or night, from anywhere in Thursley. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Why does my air conditioning run but not cool?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Check the filter and the settings first, and if that does not fix it, ring 07833 053749.
Why is my air conditioning icing up?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first and if that isn’t it, we’ll find the cause.
Why is my air conditioning showing a fault code?
Codes differ by brand, and the same code can cover several faults. Send us a photo of the display with the make and model, and we will diagnose the fault on site.
How much is an air conditioning call-out?
A diagnosis call-out is from £75 + VAT. When we’ve found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
My system uses R410A. Can it still be repaired?
Yes. Repairing and recharging existing R410A systems is still legal. R410A is getting scarcer and dearer to buy as the GB phase-down tightens, so for older systems we compare the cost of a repair with a replacement.
Air conditioning repair in Thursley: the local picture
Thursley’s centre falls inside the Thursley Conservation Area. Historic England lists about 33 buildings and structures within half a mile of the centre of Thursley, including Church of St Michael and All Angels (grade I). Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be. Census 2021 figures found about 73% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
Dirty filters and blocked drains cause more faults than people expect.

Looking after it afterwards
Simple habits make a real difference. We recommend:
- Don’t keep resetting a breaker that trips
- Ask for the leak to be found, not just a top-up
- Check the settings and the remote’s batteries first
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind and point out anything else we spotted.
Filter cleaning is the simplest prevention there is. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance and the manual shows how to clean them.
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what air conditioning repair won’t 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)
- Cooling that falls short because the system is too small
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is normally the answer)
If you’re not sure, just ring 07833 053749 or send an email and we’ll give you a straight answer.

“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.”
