Your questions about air conditioning servicing in Merston
Does my air con in Merston need a yearly service?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you cover smaller places like Merston?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
How long will the engineer be here for the service?
It takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. The number of indoor units and how easy they are to reach make the biggest difference so we’ll confirm the time when we book.
Do I need a service to keep the manufacturer’s warranty?
It depends on the brand. Some may have servicing conditions attached, so check the terms for your system. We are happy to go through them with you, and our service record shows the work was done.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Air conditioning servicing in Merston
Air conditioning pulls room air through a filter and across a cold coil many times an hour. Whatever is in the air, from dust to pet hair, collects on the filter and coil. Servicing removes it, letting air pass through the unit properly and the condensate drain away. Common call-outs are for warning lights on the indoor unit and water dripping from the indoor unit, across multi-split systems, ceiling cassettes and VRF systems.
Several units at a home near Merston can be serviced in one visit, which keeps it simple.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What a service looks like in Merston
Historic England lists about 4 buildings and structures within half a mile of the centre of Merston, including Church of St Giles (grade I). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. VOA council tax data show about 34% of homes in Merston and the neighbourhoods around it were built in 2000 or later. Access to the outdoor unit is the one detail that most changes how a visit is planned.
If you cannot remember the last service, it’s probably due.

- A system short of gas because of a leak
- Poor original installation, such as drains without a proper fall
- Heat from large windows, roof spaces or equipment beyond the system’s capacity

Common problems we fix in Merston
Each indoor unit makes water when it cools, and that water needs a clear route out. Sludge and debris can block the tray, the pipe or the pump, and the water then has nowhere to go but out of the unit.
These are the situations we see most often:
- Error codes or flashing lights on the indoor unit
- Condensate leaking into the room
- An unpleasant odour when the system runs
For a school like North Mundham Primary School, maintenance visits can be booked out of term.
What your quote should include
- What happens if the job turns out to be different on the day
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether you get F-Gas records where refrigerant is involved
What happens on the day
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes an hour or so for a single wall-mounted unit, longer for a multi-split system. A note on how to find the property and where to park makes a visit to Merston easier.
- You tell us the brand, the number of indoor units 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.
- We explain what we found and price any repair before it’s done.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Tell us about parking and loading
- Unlock any gate, garage or side passage we need

Advice
Landlords, agents and facilities managers
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
We also work for facilities teams in offices, schools and public buildings in Merston and across West Sussex. Larger buildings can be done in stages around the people who use them.
A customer’s words
“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.”
