Air conditioning repair in Stanmore, done properly
We repair air conditioning on all the main brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Systems fitted by other installers are fine too, so tell us the make and model if you know it. If the problem is a unit that has lost refrigerant and a unit blowing warm air, we can sort it out.
Air conditioning repairs in Stanmore are often in flats, offices and shops, with outdoor units on balconies, rear walls or flat roofs. Telling us where the outdoor unit is and how we reach it saves time on the visit.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
What affects the quote in Stanmore
The survey or diagnosis tells us what the work involves. The main factors are:
- What we find on the survey or diagnosis
- Whether the existing supply is suitable
- The pipe route between the units
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
Helping us quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- Your consumer unit or fuse board
- The make and model of the system, from the label
- The outside wall, roof or yard where the outdoor unit sits or would go
For a fixed-price quote, ring 07833 053749 or use the quote form with the address and a few details about the rooms or units involved. Photos help a lot. We reply to enquiries the same working day.

What we do, step by step
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. A note on parking and access helps us plan a visit to Stanmore.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Before we arrive
- Clear access to the fuse board
- Move furniture away from the wall where we’ll be working
- Name a contact who can meet us at the agreed time
Get a fixed-price quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Air conditioning repair around Stanmore
Central Stanmore is inside a conservation area. Listed buildings are part of the picture here: about 11 within half a mile of the centre, such as Church of St John (grade II*). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 43% of homes in Stanmore and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records. Let us know where the outdoor unit sits and whether a ladder is needed to reach it. London repairs often depend on reaching the outdoor unit, so access details help us plan.
For a school like Whitchurch Primary School & Nursery, urgent repairs can be booked straight away and bigger work in the holidays. Before you call, note what the unit is doing and any code on the controller.

Common questions in Stanmore
Is there an emergency air con repair line for Stanmore?
Stanmore is within our area, and the emergency line is open 24/7. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
What’s the best way to get a price for air conditioning repair in Stanmore?
Start with a short message: the address, what you need and a picture or two. Where pictures are not enough, a survey comes first and the fixed-price quote follows.
My system uses R22. Can it be repaired?
Most of the time, we recommend replacement. New R22 can’t be used to service systems, and parts for older units are getting harder to find, so we’ll quote for a modern replacement and explain why.
Why is my air conditioning icing up?
It typically points to poor airflow or a refrigerant leak. A clogged filter, a fan problem or a leak are typical. Turn it off, let the ice melt and give us a ring on 07833 053749, or email if that’s easier.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Why is water dripping from my indoor unit?
The condensate drain or pump is the usual cause: a blockage, a kink or a pump that has stopped. Switch the unit off to avoid water damage, then call us.
