Air conditioning repair in Mitcham, done properly
A symptom is only a clue: warm air, drips and error codes can each have several causes. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, so we diagnose before we repair. The work covers heat pumps, multi-split systems and ducted systems, and the jobs we see most are a unit that barely blows any air and new noises from the system.
In a London area like Mitcham, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Mitcham questions
Is there an emergency air con repair line for Mitcham?
Yes. Our 24/7 emergency line covers Mitcham. 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 Mitcham?
We do: Mitcham falls inside our working area. Tell us a little about the job and we will take it from there.
Why is my air conditioning blowing warm air?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, then call us on 07833 053749, or email if that’s easier if it’s still not cooling.
How long does the work take?
Your quote will say how long we expect to be there. Most of the time, it takes as long as the fault needs, from a quick fix to a return visit for parts.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Is it legal to repair an R410A system?
Yes. Any leak is repaired before recharging, and the work is recorded, and we tell you honestly whether a repair is worth it on an older system.

- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Before we arrive

Customers normally contact us after spotting one of these:
- Ice on the pipework or the coil
- A unit that barely blows any air
- A flashing light and a system that will not run
If your system near Mitcham Eastfields station stops in a hot spell, our 24/7 line is open.
Before booking anyone
- What the manufacturer’s warranty covers and for how long
- Why the equipment they’re quoting suits the job
- Whether you get F-Gas records where refrigerant is involved
What air conditioning repair cannot fix

- No power to the building at all
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
Not sure which it is? You can ring 07833 053749 or use the quote form and we’ll tell you honestly before you book.
