Air Conditioning Repair in Tonwell
Air conditioning repair in Tonwell from an F-Gas certified company, with warranty terms explained brand by brand. We reply to enquiries the same working day.
- A system that needs topping up again
- A unit that barely blows any air
- A system that won’t switch on
How it works
Think of the visit in three stages: look, put right 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. Most of the time goes on the middle part, which takes an hour or two to diagnose most faults, with the repair time depending on what we find. A note on how to find the property and where to park makes a visit to Tonwell easier.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- Once the cause is found, we explain it and fix the price for the repair.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- We run the system, check it’s working properly and note anything else that needs attention.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas

Advice
Air conditioning repair for homes and businesses in Tonwell
A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. If you are dealing with a system that keeps cutting out and drips from the indoor unit, we can sort it out.
We plan the trip to Tonwell so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

When it’s something else
Not every problem is solved by air conditioning repair, and we will tell you before any work starts. It will not put right:
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
- An R22 system that has lost its refrigerant
- Cooling that falls short because the system is too small
Not sure which it is? You can give us a ring on 07833 053749 or drop us a line and we’ll tell you honestly.

What the work involves, system by system
Multi-split systems
With several pipe runs, finding a leak on a multi-split takes method. We test each run to find it before the system is repaired, tested and recharged.
Ducted and cassette systems
Ducted units and cassettes sit above the ceiling and access is part of the job. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.

What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
Questions from Tonwell
Is there an emergency air con repair line for Tonwell?
The emergency line is open around the clock, and Tonwell is one of the places it covers. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Is Tonwell in your area for air conditioning repair?
Yes. Tonwell is one of the places we cover. Tell us a little about the job and we will take it from there.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first and if that is not it, we’ll find the cause.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
Why is my air conditioning showing a fault code?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Write down the code and turn the unit off if it has stopped, and ring us on 07833 053749 or drop us a line.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
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 new systems, we recommend a brand and model to suit the job and tell you why.
