Air conditioning repair for homes and businesses in Thornborough
A diagnosis call-out is from £75 + VAT. When the cause is found, the repair is priced before anything else is done and nothing goes ahead without your say-so. The work covers VRF systems, ceiling cassettes and heat pumps, and people most often call us about frost on the pipework and poor airflow even with clean filters.
Around Thornborough, outdoor units often sit close to gardens and hedges, so leaves, seeds and cobwebs on the coil are worth checking first.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes as long as the fault needs, from a quick fix to a return visit for parts. Visits to Thornborough are agreed with you in advance and planned so the job can be finished in one trip where possible.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- At the property, readings and tests narrow the problem down to its cause.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- Finally the system is tested in operation and you get a note of the fault and the fix.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Let us know if the units are on a roof, a high wall or in a locked area
- Move furniture away from the wall where we will be working
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.
Advice
Common problems we fix in Thornborough
Water dripping from an indoor unit is normally about the condensate. A blocked or kinked drain, a failed pump or a unit that is not level are the usual causes, while ice that forms on the coil and then melts can also cause drips.
If any of these sounds familiar, it’s worth a diagnosis:
- Ice on the pipework or the coil
- A system that will not switch on
- Air conditioning running but not cooling
When cooling fails at a school like Thornborough Infant School, we can time non-urgent repair work around lessons.
What to look for in a quote
- Which VAT rate the quote uses, and why
- Whether the price is fixed or an estimate
- Why the equipment they’re quoting suits the job
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.

What else we do in Thornborough
When it’s something else
Not every problem is solved by air conditioning repair, and we’d rather say so up front. It doesn’t solve:
- A leak on an old R22 system
- A unit whose parts are no longer made (replacement may be the only option)
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
If you’re not sure, just ring 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer before booking.

Thornborough: your questions answered
Can you do air conditioning repair in Thornborough?
Yes. Thornborough is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Is Thornborough within the area you cover?
Yes. Thornborough is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
How long will you be on site?
Your quote will say how long we expect to be there. In most cases, it takes as long as the fault needs, from a quick fix to a return visit for parts.
Can you repair an R22 air conditioning system?
R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a leak normally makes replacement the sensible route. We’ll set out the options and quote for a replacement where it makes sense.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
When will I hear back?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
When air con fails in Thornborough
Thornborough’s centre falls inside the Thornborough Conservation Area. About 31 listed entries lie within half a mile of central Thornborough, Church of St Mary (grade II*) among them. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. The Valuation Office Agency’s council tax figures show about 41% of homes in Thornborough and the neighbourhoods around it were built in 2000 or later, and about 74% of households live in detached or semi-detached houses, according to Census 2021 figures. A photo of the outdoor unit and its surroundings tells us what access the visit needs.
A photo of the error code and the unit’s rating label helps us plan the repair.

From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
