About our air conditioning repair in Thornhill
Older systems raise a fair question: repair or replace?. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers multi-split systems, ducted systems and wall-mounted split systems, and common reasons people get in touch are air conditioning running but not cooling and a system that needs topping up again.
Outdoor units around Thornhill often sit near hedges, trees and lawns, and leaves or grass cuttings on the coil are a common reason for poor cooling. We check the coil early on.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Why it’s worth doing now in Thornhill
If your system uses R22, the options are narrower. R22 depletes the ozone layer, and servicing with new R22 isn’t allowed, so a refrigerant fault on an R22 system normally points to replacement. We will tell you honestly and quote for a replacement if it makes sense. An early booking makes the visit to Thornhill easier to arrange.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you’re not sure what’s needed, phone 07833 053749 or send an email and we’ll give you an honest view and a fixed price.

How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Because we plan from pictures or a survey, a job in Thornhill can usually be finished in one visit.
- You describe the fault, the make and any error code, ideally with a photo.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Preparing for the visit
- Clear access to the fuse board
- Keep pets out of the rooms we’re working in
- Let us know if the building has a permit or sign-in process
How to get a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price so you know the cost before we begin.

Signs you need air conditioning repair in Thornhill
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Corrosion on coils can also cause leaks over time and many leaks are slow enough to go unnoticed for a while.
Common reasons people call us include:
- Water dripping from the indoor unit
- Ice on the pipework or the coil
- Rattling, buzzing or grinding noises
The make, model and error code are the most useful things to tell us.

Thornhill questions
Who do I call if my air conditioning fails in Thornhill out of hours?
Yes. Our 24/7 emergency line covers Thornhill. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Does being near the sea make a difference to air conditioning repair in Thornhill?
It can, as Thornhill is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. We look for corroded coils, fixings and connections on coastal repairs.
Will I get records for the system?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we will gladly show you ours.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
