Air con repairs in Sonning
Our engineers work in Sonning on air conditioning repair. A look at the job first, a fixed-price quote and written records at the end.
- Ice forming on the indoor unit or pipes
- A noisy indoor or outdoor unit
- A system that needs topping up again
What happens on the day
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, which takes as long as the fault needs, from a quick fix to a return visit for parts. Work in Sonning is booked in advance at a time that suits you.
- Diagnose: test the system until the cause is clear.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
Before we arrive
- Clear access to the fuse board
- Arrange for someone to be there to let us in
- Have the make and model of any existing unit to hand

How we handle air conditioning repair in Sonning
Diagnosis call-outs start from £75 + VAT. When the cause is found, the repair is priced before anything else is done, so you can decide with the facts in front of you. The work covers ducted systems, heat pumps and multi-split systems, and the jobs we see most are a system that keeps cutting out and frost on the pipework.
Outdoor units in a place like Sonning can be near hedges and fields, and a coil clogged with leaves or seeds is a common cause of weak cooling.
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 Sonning
Is there an emergency air con repair line for Sonning?
Yes: ring the emergency line, day or night, from anywhere in Sonning. Have the make, model and error code ready, and we will talk you through what happens next.
Do you cover smaller places like Sonning?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
How much does an air conditioning repair cost?
The first step is a diagnosis, from £75 + VAT, followed by a fixed price for the repair. You decide before any repair work starts.
Why is there ice on my air conditioning pipes?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Switch the system off, let it thaw and give us a ring on 07833 053749.
What does the error code on my air conditioning mean?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Note the code and switch the system off if it isn’t working, and phone us on 07833 053749 or fill in the contact form.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.

What else we do in Sonning
Different systems, different jobs
Fans and compressors
Fan motors and bearings wear over time, and the first sign is often noise or weak airflow. A worn fan motor can normally be replaced, depending on parts availability.
Refrigerant leaks
Adding refrigerant without a repair isn’t a fix and the gas simply leaks out again. We always find and fix the leak first.
Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- Have the system serviced once a year
- Turn it off and let ice clear before the visit
- Note any error code, or take a photo of the display
A returning symptom is worth reporting quickly. Let us know what the system is doing and any code on the display and we will come back to it.
Small changes are worth acting on. Drips, noises, weak airflow and error codes are early warnings, and early diagnosis normally means a smaller repair.

Pricing air conditioning repair in Sonning
The price is fixed before any work begins. It takes into account:
- How many units are involved
- The electrical supply and whether a new circuit is needed
- How easy the units are to reach
Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered, and you’ll get one fixed price.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- A few pictures of the room and the wall the unit is on, or will go on
- The postcode and whether it’s a home, flat or business
- Where the outdoor unit is, or where you’d like it
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
From one of our customers
“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.”
