Air conditioning repair in Charndon
Any repair we carry out in Charndon starts the same way: fault codes, electrics, airflow, drain and refrigerant are all checked. Then we explain what’s wrong and give you a fixed price to put it right. The work covers VRF systems, heat pumps and ducted systems, and common reasons people get in touch are a unit that won’t start and a unit that has lost refrigerant.
Around Charndon, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Why act early in Charndon
The rules on refrigerant affect repairs. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement. A dirty or faulty system works harder and costs more to run.
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before we start, so there are no surprises.
Why book with us
- MCS certification for heat pump work
- A reply the same working day
- Manufacturer’s warranty terms explained on your quote
- A fixed price before any work starts

What a repair looks like in Charndon
Charndon is about 49 miles from central London, well within the area we cover from our base in East Grinstead. About 32% of homes in the Charndon area have been built since 2000, according to Valuation Office Agency council tax records, and the 2021 Census found about 79% of households in detached or semi-detached houses. Tell us where your outdoor unit is and how to reach it, so we can plan the visit.
Many breakdowns start small, with a drip, a smell or a unit that takes longer to cool. The rating label on the unit gives the model number, which helps us bring the right parts.

Your questions about air conditioning repair in Charndon
Is Charndon within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Do you cover Charndon for emergency air conditioning repairs?
Charndon 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.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before any work starts, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
What can I do with an old R22 system?
Replacement is usually the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so we’ll quote for a modern replacement and explain why.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
How the visit works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes an hour or two to diagnose most faults, with the repair time depending on what we find. Somewhere like Charndon, it helps to know about lanes, gates and where to park.
- You describe the fault, the make and any error code, ideally with a photo.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- 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.
- We run the system, check it’s working properly and note anything else that needs attention.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Let us know if the units are on a roof, a high wall or in a locked area
- Tell us about any building rules, permits or sign-in
Getting a price
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price so you know the cost before we begin.

For landlords and property managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork and we’ll copy in whoever needs it.

What else we do in Charndon
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what air conditioning repair will not do:
- Heat gains the system was never designed for
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is normally the answer)
- A discontinued model with no parts available
If you’re not sure, just ring 07833 053749 or drop us a line and we’ll give you a straight answer.
Parts of the system we cover
- VRF systems
- Ducted systems
- Multi-split systems
- Wall-mounted split systems
- Heat pumps
- Ceiling cassettes
