What the work involves, system by system
Refrigerant performance and leak checks
F-gas leak checks are required for systems from 5 tCO2e upwards, at least yearly up to 50 tCO2e and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e doesn’t need them.
Condensate drains and pumps
When the system cools, every indoor unit makes water. We clean the drain tray and clear the pipe so it flows properly.
Air conditioning servicing in Charlton
For an annual service, the price is £95–£150 + VAT, and we confirm the figure before we book you in. Multi-split, ducted and commercial systems are priced once we know what’s there. Either way, you know the cost before the engineer arrives. If you are dealing with smells coming from the indoor unit and no service record for the last year or more, we can sort it out.
In a village like Charlton, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What we do, step by step
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. We agree a date with you and plan the visit to Charlton so we arrive with what’s needed.
- First, we agree a time and confirm the cost of the service.
- We switch the system on and check it in operation.
- We clean the filters, coils and fans and clear the condensate drain.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- It’s run once more to confirm all is well, and the record is left with you.
Before we arrive
- Mention any parking restrictions near the property
- Tell us about any building rules, permits or sign-in
- Clear the space around the indoor unit, or where it will go

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or drop us a line.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.

What we are called out for in Charlton
Outdoor units sit in the weather all year. Leaves, dirt and debris collect on the coil and around the casing and that restricts the airflow it relies on.
Look out for any of the following:
- Systems that haven’t been serviced for a while
- Error codes or flashing lights on the indoor unit
- Leak check records that need bringing up to date
If you look after a school such as Littleton CofE Infant School, servicing is easiest in the holidays.

Charlton questions
Is Charlton within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How often do you service systems in Charlton?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can you come out in an emergency?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Does the manufacturer’s warranty require regular servicing?
The warranty comes from the manufacturer, on its own terms. Read the conditions for your brand, as they may include servicing, and keep each service record with the warranty paperwork.
Can I have a maintenance contract for my air conditioning?
Yes, and the schedule is set around your system. We agree the cost up front and you get a record after every visit.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
A customer’s words
“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.”
