Common questions in Great Dunmow
How often do you service systems in Great Dunmow?
For most homes, once a year. 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 Great Dunmow?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can you come out in an emergency?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will advise on what to do next.
What does an air con service involve?
A full clean and check of the system. Filters, coils and drains are cleaned, and the electrics, controls and refrigerant circuit checked, and F-gas leak checks where they apply.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
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. Many small split systems fall below it: 3 kg of R32, for example, is about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Do I need a service to keep the manufacturer’s warranty?
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.
Air conditioning servicing in Great Dunmow
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. The terms differ from brand to brand, so it’s worth reading yours, and we can explain what yours says. Our service record shows the work was done. If the problem is new noises from the indoor or outdoor unit and a unit showing a fault code, we can sort it out.
In a place like Great Dunmow, the outdoor unit often sits near a garden, hedge or trees, so the outdoor coil can clog with leaves and seeds. Every service includes cleaning it.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Air conditioning servicing in Great Dunmow: the local picture
The Valuation Office Agency’s council tax figures show about 44% of homes in the Great Dunmow area were built in 2000 or later, and Census 2021 figures found about 63% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. Great Dunmow’s centre falls inside the Great Dunmow Conservation Area. There are 2 conservation areas within a mile of the centre of Great Dunmow. Listed buildings are part of the picture here: about 153 within half a mile of the centre, such as The Clock House (grade I). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
Booking before the first hot spell means the system is ready when you need it. If you look after a school such as Dunmow St Mary's Primary School, servicing is easiest in the holidays.

Different systems, different jobs
Refrigerant performance and leak checks
tCO2e is the refrigerant charge in kg multiplied by its global warming potential, divided by 1,000. As an example, 3 kg of R32 comes to about 2.0 tCO2e, while 3 kg of R410A is about 6.3 tCO2e. We read the charge from the unit’s label and work it out for you.
Condensate drains and pumps
Slime and debris build up in drain trays over time. Cleaning them helps with drips and with musty smells.
Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
What air conditioning servicing can’t fix
In fairness, some problems need a different answer:
- Lost refrigerant, where the fix is a leak repair
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
- A failed compressor, fan motor or circuit board, which needs a repair
If in doubt, phone 07833 053749 or use the quote form and we’ll say what we think before booking.
