Common problems we fix in Plummers Plain
Small refrigerant leaks do not announce themselves. The system just cools or heats a little less well each year, until it can’t keep up on the hottest or coldest days.
Look out for these signs:
- F-gas leak checks falling due
- Frost or ice on the refrigerant pipes
- A service that’s overdue
Booking before the first hot spell means the system is ready when you need it.
Before booking anyone
- Whether anyone has checked the property or the system first
- Exactly what the price includes, from supply and fitting to commissioning
- If the figure could change on the day
Air conditioning servicing in Plummers Plain, done properly
A service is as much a check-up as a clean. The engineer checks fans, pipe insulation, controls and electrical connections, and tells you about anything that looks like it’s heading for trouble. We’re often asked to deal with error codes or flashing lights on the indoor unit and smells coming from the indoor unit, on ceiling cassettes, air-to-air heat pumps and VRF systems.
For a home in or near Plummers Plain, a service once a year suits most systems, ideally in spring before the warm weather.
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.

Common questions in Plummers Plain
Can you do air conditioning servicing in Plummers Plain?
We do: Plummers Plain falls inside our working area. Tell us a little about the job and we will take it from there.
How often should air conditioning in Plummers Plain be serviced?
Once a year suits most home systems. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
What’s included in an air conditioning service?
Filters, coils, fans and the condensate drain are all cleaned and checked. The electrics, controls and refrigerant circuit are tested too plus a leak check on systems that need one.
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 it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you do service contracts for air con?
Yes, and the schedule is set around your system. We agree the cost up front and you get a record after each visit.
Does my air conditioning need an F-gas leak check?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). From 5 to under 50 tCO2e, leak checks are required at least every 12 months, and from 50 to under 500 tCO2e every 6 months. Hermetically sealed systems holding less than 10 tCO2e do not need them.
Do I need a service to keep the manufacturer’s warranty?
It depends on the brand. Some may have servicing conditions attached so it’s worth reading yours. We’re happy to go through them with you, and our service record shows the work was done.
What you can do yourself, and what needs us
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749 or use the quote form.

Aftercare tips
After the visit, a few habits help:
- Know your manufacturer’s servicing conditions
- Keep doors and windows closed while the system is cooling
- Keep to an annual service, or more often if needed
Where the system needs F-gas leak checks, the result is recorded, and the next check is due within the period the rules set. We can book it in ahead of time.
Book a service at least once a year, and more often if the system works hard or the rules require it.

What else we do in Plummers Plain
How the visit works
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes an hour or so for a single wall-mounted unit, longer for a multi-split system, and we tidy up before we leave. For a village like Plummers Plain, tell us about narrow lanes, gates and parking when you book.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- We run the system first and see how it’s performing.
- Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- We leave you a record of the service and explain anything we found.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Plan for pets to be kept clear during the visit
- Let us know if the building has a permit or sign-in process

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
