Different systems, different jobs
Multi-split systems
Refrigerant leaks on a multi-split can be anywhere on several pipe runs. We test each run to find it before the system is repaired, tested and recharged.
Circuit boards and sensors
Boards and sensors are the system’s nervous system. A failed sensor can make a unit stop, run oddly or show an error code, and boards can fail after a power surge or with age.
How we handle air conditioning repair in Titmore Green
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. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. If the problem is ice forming on the indoor unit or pipes and an error code or flashing light on the unit, we can sort it out.
In a village like Titmore Green, most air conditioning we repair is in homes, garden rooms and the occasional pub or village business. Describe the fault and send a photo of the unit’s label so we can plan the visit.
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.

Air conditioning repairs in Titmore Green: local notes
The last census (2021) found about 40% of households in terraced houses. In a terrace, the route to the back garden decides how the visit is planned. Historic England lists about 12 buildings and structures within half a mile of the centre of Titmore Green, including Redcoats Farmhouse Hotel (grade II*). If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
The rating label on the unit gives the model number, which helps us bring the right parts. When cooling fails at a school like Wymondley Junior Mixed and Infant School, we can time non-urgent repair work around lessons.

After we have gone
Every system needs looking after, and most of it is easy. Our tips:
- Turn the system off if it’s dripping water
- Turn it off and let ice clear before the visit
- Send us a photo of any code on the display
The repair is written up: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Sensible use helps. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs, so it is not running flat out all day.
Titmore Green: your questions answered
Can you do air conditioning repair in Titmore Green?
We do: Titmore Green falls inside our working area. Tell us a little about the job and we will take it from there.
Who do I call if my air conditioning fails in Titmore Green out of hours?
Yes. Our 24/7 emergency line covers Titmore Green. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Can you still repair R410A air conditioning?
Yes, repairs and recharges on existing R410A systems remain legal. As the GB phase-down continues, R410A is getting harder and dearer to buy and we talk through repair against replacement for older systems.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
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 any issues with how it was fitted. Any work is priced before it goes ahead.
What does the error code on my air conditioning mean?
An error code points us in the right direction, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and call us on 07833 053749 or email us.
How it works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes anything from an hour or so to a full day, depending on the fault and the parts. For a village like Titmore Green, tell us about narrow lanes, gates and parking when you book.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- Finally the system is tested in operation and you get a note of the fault and the fix.
Before we arrive
- Tell us about parking and loading
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Plan for pets to be kept clear during the visit
