Welling air conditioning servicing
Air conditioning servicing for Welling, from F-Gas certified engineers, with warranty terms explained brand by brand. We reply to enquiries the same working day.
- Smells coming from the indoor unit
- New noises from the indoor or outdoor unit
- Warning lights on the indoor unit
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. The work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Let us know who controls access to the building in Welling, as that saves time on the day.
- We book a time that suits you and confirm the price.
- Before any cleaning, the system is run so we can see how it behaves.
- 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
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit

About our air conditioning servicing in Welling
People in Welling book a service for all sorts of reasons: a musty smell, weak cooling, water dripping indoors or simply because it’s been a while. The same full set of checks applies whatever prompted the call. The work covers ducted systems, multi-split systems and wall-mounted split systems, and the jobs we see most are warning lights on the indoor unit and noisy fans or rattling from the outdoor unit.
Systems in Welling often run in both summer and winter, which is a good reason for a yearly service. In London, outdoor coils collect dust, grime and leaves, which a service clears.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

When it’s something else
To be straight with you, there are a few things this work won’t fix:
- A system short of gas because of a leak
- Cooling capacity that doesn’t match the space
- Heat gains the system was never sized for
If in doubt, phone us on 07833 053749 or email us and we’ll say what we think before you book.
What the work covers
- VRF systems
- Air-to-air heat pumps
- Wall-mounted split systems
- Ceiling cassettes
- Ducted systems
- Multi-split systems
What happens if it’s left?
A dirty filter or coil makes the system work harder for the same result. A service puts that right with a clean and lets the system run as it was designed to. Planning ahead in Welling means you choose the date, not the weather.

Questions from Welling
What’s the best way to get a price for air conditioning servicing in Welling?
Start with a short message: the address, what you need and a picture or two. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
Does my air con in Welling need a yearly service?
Normally once a year for homes, more often for busy business systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What does an air con service involve?
A clean of the parts that collect dirt and a check of the parts that do the work. That means filters, coils and drains, plus electrical connections, controls and refrigerant performance, and F-gas leak checks where they apply.
How long will you be on site?
That depends on what’s involved, but as a guide it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. We’ll give you a firmer idea when we quote.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Air conditioning servicing in Welling: the local picture
Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as Danson Park Mansion (grade I). If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. About 75% of homes in the Welling area were built between the wars, according to the Valuation Office Agency’s council tax figures, and about 71% of households live in detached or semi-detached houses, according to the 2021 Census. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools.
Schools such as Danson Primary School can book servicing for half term or the summer break, when rooms are empty. Businesses close to Welling station can book an early or late slot so the service does not get in the way of trade.

How the job changes from property to property
Filters
The filter is the first line of defence for the indoor unit. We clean them and check for damage and we will say if one needs replacing.
Wall-mounted, ducted and cassette units
Ceiling cassettes are common in offices, shops and restaurants. We drop the grille to clean the filters and check the condensate pump.
From one of our customers
“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.”
