Air con servicing in Ley Green
Our engineers work in Ley Green on air conditioning servicing. A look at the job first, a fixed-price quote and written records at the end.
- Warning lights on the indoor unit
- Systems that need a 6 or 12-monthly leak check
- Systems that haven’t been serviced for a while
What we are called out for in Ley Green
Each indoor unit makes water when it cools, and that water needs a clear route out. Debris in the tray or a sticky pump can stop it draining, and the water then has nowhere to go but out of the unit.
These are the situations we see most often:
- Systems that need a 6 or 12-monthly leak check
- A service that’s overdue
- New noises from the indoor or outdoor unit
A service once a year suits most home systems, and some business systems need more.
Comparing quotes
- Whether the company is F-Gas certified, and whether you can check it

Air conditioning servicing for homes and businesses in Ley Green
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We service systems in Ley Green and across Hertfordshire, for most leading brands. If the problem is an unpleasant odour when the system runs and noisy fans or rattling from the outdoor unit, we can help.
We plan the trip to Ley Green and can service more than one unit in one visit, which keeps it simple.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Looking after it afterwards
Looking after it is simple, and it makes the next visit easier:
- Keep plants, bins and stored items away from the outdoor unit
- Shut doors to the room so the system isn’t cooling the whole house
- Keep to an annual service, or more often if needed
Run the system for a while after the visit and check it feels right. If you notice anything unusual, ring 07833 053749 and we’ll talk it through.
Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than once the system has stopped.
How the visit works
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A few pictures help us make the most of a visit to Ley Green.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- The outdoor unit gets its own clean, with leaves and debris cleared away.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- If a repair is needed, you hear why and what it costs before anything is done.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the building has a permit or sign-in process
Ask for a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Common questions in Ley Green
Do you cover Ley Green for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Ley Green is part of that. Just phone us on 07833 053749 or fill in the contact form with a few details.
Will you come out to Ley Green?
Yes. Ley Green is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Is an F-gas leak check a legal requirement for my system?
Only if the system is at or above the threshold of 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We read the charge from the label and work it out for you.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
What does an annual air con service cost?
£95–£150 + VAT covers the annual service with the figure confirmed before the visit. If the service finds a fault, we price the repair separately and only go ahead if you agree.

Keeping systems in Ley Green running
About 72% of households live in detached or semi-detached houses, according to Census 2021 figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. Listed buildings are part of the picture here: about 15 within half a mile of the centre, such as Church of St Mary (grade I). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
If you look after a school such as Preston Primary School, servicing is easiest in the holidays.

Honest limits
In fairness, some problems need a different answer:
- A refrigerant leak, which needs finding and repairing, not topping up
- A system that is too small for the room it serves
- Poor original installation, such as drains without a proper fall
