Air conditioning repair in Lexden, done properly
Diagnosis call-outs start from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead and nothing goes ahead without your say-so. If the problem is rattling, buzzing or grinding noises and a fault code on the display, we can help.
Outdoor units around Lexden 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.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Lexden questions
Will you come out to Lexden?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you do air conditioning repair in Lexden?
Yes. We work across London and the South East from our base in East Grinstead, and Lexden is part of that. Get in touch with the details and we reply the same working day.
How long does the work take?
We will confirm the time with your quote. As a guide, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
My system uses R22. Can it be repaired?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a leak typically makes replacement the sensible route. We explain the options and quote for a new system if that is the answer.
Why is my air conditioning leaking water?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and ring us on 07833 053749 or email us.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Different systems, different jobs
Condensate drains and pumps
The drain is cleared, the pump tested and the fall checked until the condensate runs away properly. Failed pumps are replaced and test it before we leave.
VRF systems
In a VRF system, many indoor units share outdoor plant. We use the system’s fault history and codes, then test to confirm and the repair is priced before any work starts.
Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
- A unit whose parts are no longer made (replacement may be the only option)
- A building problem rather than a system fault
Not sure which it is? You can call us on 07833 053749 or drop us a line and we will tell you honestly.

What we do, step by step
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, test what we have done and talk you through it. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of the existing unit and its label help with repairs and servicing near Lexden.
- You describe the fault, the make and any error code, ideally with a photo.
- At the property, readings and tests narrow the problem down to its cause.
- Once the cause is found, we explain it and fix the price for the repair.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- Before leaving, we run it through its modes and write up what was found and done.
Before we arrive
- Tell us about parking and loading
- Keep pets and children away from the work area
- Move furniture away from the wall where we’ll be working

Owner checks or an engineer?
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Before you call us about a fault, a few checks can save a visit: 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 ring us on 07833 053749 or send an email.
