- Drips or damp patches below an indoor unit
- Systems that need a 6 or 12-monthly leak check

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 for most homes, and longer where there are several indoor units or a ducted system. A note on how to find the property and where to park makes a visit to Highleigh easier.
- You tell us the brand, the number of indoor units and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
Preparing for the visit
- Mention any parking restrictions near the property
- Plan for pets to be kept clear during the visit
- Mention any roof access, ladders or high-level work

Air conditioning servicing in Highleigh, done properly
Some systems need F-gas leak checks by law, and some don’t. GOV.UK sets the frequency by the system’s tonnes of CO2 equivalent (tCO2e): at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. We work out where your system sits and check it accordingly. Common call-outs are for a musty or damp smell when the unit starts and drips or damp patches below an indoor unit, across multi-split systems, wall-mounted split systems and ducted systems.
In a village like Highleigh, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What a service looks like in Highleigh
Highleigh lies within about 2 miles of the sea. Near the sea, rinsing and checking the outdoor coil for corrosion is an important part of every service. Brook Cottage, listed at grade II, is one of roughly 11 protected buildings and structures in the half-mile around Highleigh’s centre. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be. The last census (2021) found about 77% of households in detached or semi-detached houses. If the outdoor unit is high up or behind a locked gate, mention it when you book.
Site managers at schools like Sidlesham Primary School can have the site’s units serviced during a holiday. A service once a year suits most home systems, and some business systems need more.

Leave it or put it right?
Smells from an indoor unit tend to come back each time it runs. Cleaning the coil, the fan and the drain tray deals with the cause instead of covering it up. An early booking makes the visit to Highleigh easier to arrange.
The cost depends on the system and the number of rooms or units, 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.

We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Pipework or drainage that was badly installed in the first place
- A system short of gas because of a leak
- Rooms that gain heat faster than any unit could cope with

Looking after your system
A little care keeps the system in better shape. Our advice:
- Read the warranty conditions for your brand
- Hold on to every service report
- Rinse the indoor unit filters every few weeks when the system is in heavy use
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. We agree the visits and the cost up front so you do not have to remember.
Don’t ignore small changes. Odd noises, smells and drips are cheaper to sort out before they grow than after a breakdown.
Your questions about air conditioning servicing in Highleigh
Does being near the sea make a difference to air conditioning servicing in Highleigh?
It can, as Highleigh is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. Regular servicing, with the outdoor coil cleaned and checked, helps a coastal system last.
Does my air con in Highleigh need a yearly service?
Once a year suits most home systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Is an F-gas leak check a legal requirement for my system?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Does the manufacturer’s warranty require regular servicing?
The answer is in your manufacturer’s warranty conditions. Where servicing is a condition, keeping an annual service record helps show the terms were followed, and we can explain what your brand asks for.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
