Air conditioning repair in Three Mills
Age alone does not decide whether a repair is worth it. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. If you are dealing with water dripping from the indoor unit and a system that keeps cutting out, we can sort it out.
In a London area like Three Mills, a lot of the systems we repair serve flats and small offices, with outdoor units on balconies, rear walls or flat roofs. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What air conditioning repair can’t fix
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- A building problem rather than a system fault
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
If you’re not sure, just phone us on 07833 053749 or drop us a line and we’ll give you a straight answer before booking.
Where we work
- Ducted systems
- Wall-mounted split systems
- Multi-split systems
- Ceiling cassettes
- Heat pumps
- VRF systems
Leave it or put it right?
Leaving a fault seldom makes it go away. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should and early diagnosis typically keeps the repair simpler. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Three Mills early.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so there are no surprises.

Three Mills: your questions answered
How do I get a quote for air conditioning repair in Three Mills?
Send us photos of the room or the system and a few details about the property. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
Is there an emergency air con repair line for Three Mills?
The emergency line is open around the clock, and Three Mills is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
How long will you be on site?
We will confirm the time with your quote. As a guide, the work takes anything from an hour or so to a full day, depending on the fault and the parts.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Why is my air conditioning blowing warm air?
There are several possible causes, from simple to serious. We read any fault code and test the system to find which, then give you a fixed price to fix it.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How we price air conditioning repair
A fixed price needs a few facts first. We check:
- A single visit or a regular plan
- The distance and route between the indoor and outdoor units
- Whether we need access equipment for high-level work
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before work begins.
Before you get in touch
Simple jobs can often be priced from photos and some basics. Useful things to send:
- The outdoor side of the property, including any roof or flat area
- The paperwork from the last service, if you have it
- A short video of any fault, such as a noise or a flashing light
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we have looked at the job, from photos or on a survey, you get a fixed price. To get going, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.

The process
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of the room and where the outdoor unit could go let us plan most of a visit to Three Mills in advance.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- Where a repair doesn’t make sense, you’ll hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
Before we arrive
- Tell us about parking and loading
- Move furniture away from the wall where we’ll be working
