Air conditioning repair in Marlow, done properly
We treat a faulty system the way a doctor treats a patient: find the cause, put it right and check it’s healthy before we leave. Guesswork costs money, and replacing a board when the fault is a sensor leaves the problem in place. Common call-outs are for a unit that has lost refrigerant and water leaking from the unit or through the ceiling, across ceiling cassettes, wall-mounted split systems and ducted systems.
For a repair in Marlow, a photo of the error code and the unit’s rating label is a great start. We can then see the make, model and refrigerant, so we can plan the visit properly.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Questions from Marlow
Can I get a fixed-price quote for air conditioning repair in Marlow?
The easiest way is to phone us on 07833 053749 or email us with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Is Marlow in your area for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Marlow is part of that. Get in touch with the details and we reply the same working day.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Do you have a 24/7 line for breakdowns?
Yes, 24/7. Urgent cases include water leaking through a ceiling or a server or comms room overheating and we will tell you what to do first. The number is 07833 053749.
Does servicing affect my warranty?
For some brands, yes. Send us the make and model and we’ll tell you what the manufacturer expects and stick to the interval they set.
Will you work on another installer’s system?
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.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
What happens if it’s left?
Waiting for hot weather to see whether a fault sorts itself out rarely works. If the system is faulty now, it will be faulty in a heatwave, when you need it most, so it’s worth having it diagnosed while you can plan the repair. A dirty or faulty system works harder and costs more to run.
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.

For landlords and property managers
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side, and the paperwork can go to both.
Safe owner checks
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call us on 07833 053749 or email us.
How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. Pictures of the space, the fuse board and the outside wall are a good start for a job in Marlow.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- The sign-off: the system tested in operation and the work recorded.
Before we arrive
- Mention any roof access, ladders or high-level work
- Clear a path to the units and the space around them
- Tell us about any building rules, permits or sign-in
