Dollis Hill air conditioning servicing

How we handle air conditioning servicing in Dollis Hill
Some systems need F-gas leak checks by law, and some don’t. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We tell you which band your system falls into and carry out the checks it needs. The work covers ducted systems, multi-split systems and wall-mounted split systems, and common reasons people get in touch are a musty or damp smell when the unit starts and error codes or flashing lights on the indoor unit.
In Dollis Hill, a business system may need a leak check by law as well as a service, depending on how much refrigerant it holds. The check is recorded, with the next date noted.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Landlords, agents and facilities managers
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.

The process
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Let us know who controls access to the building in Dollis Hill, as that saves time on the day.
- You tell us the brand, the number of indoor units and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- We explain what we found and price any repair before it’s done.
Before we arrive
- Clear access to the fuse board
- Mention any managing agent or landlord rules we need to follow
- Mention any roof access, ladders or high-level work

When it’s something else
We’d rather tell you now than sell you work that won’t help, so here are the limits:
- Heat gains the system was never sized for
- Pipework or drainage that was badly installed in the first place
- A system short of gas because of a leak

Dollis Hill: your questions answered
How do I get a quote for air conditioning servicing in Dollis Hill?
Send us photos of the room or the system and a few details about the property. Where photos are not enough, a survey comes first and the fixed-price quote follows.
How often should air conditioning in Dollis Hill be serviced?
Usually once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Do you top up refrigerant during a service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.
Will servicing keep my manufacturer’s warranty valid?
It depends on the brand. Some warranties may include conditions about regular servicing so it’s worth reading yours. We can explain the terms, and each visit is recorded.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. 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 can tell you which band your system falls into.
What do you check on an air conditioning service?
We clean the filters and coils, clear the condensate drain and check the fans. We also check the electrical connections, the controls and the refrigerant performance plus a leak check on systems that need one.
What a service looks like in Dollis Hill
About 47% of homes in Dollis Hill and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records, and about 48% of households live in flats, according to Census 2021 figures. Outdoor units serving flats can be awkward to reach, so let us know where yours is. City dust and debris build up on London outdoor units, which is why servicing matters. Dollis Hill’s centre falls inside a designated conservation area. There are 2 conservation areas within a mile of the centre of Dollis Hill. On the National Heritage List, around 3 entries fall within 0.5 miles of the middle of Dollis Hill; Church of St Michael (grade II) is one. That only matters for replacements, where a new outdoor unit on a protected building can need consent.
If you look after a school such as Our Lady of Grace Catholic Junior School, servicing is easiest in the holidays. Businesses close to Brent Cross West station can book an early or late slot so the service does not get in the way of trade.

There’s a railway station in Dollis Hill itself: Brent Cross West station. Other landmarks nearby include Brent Cross Shopping Centre (1 mile north-east) and St Andrew's Hospital (less than half a mile south). Green spaces nearby include Darland's Lake and Parliament Hill.
After we’ve gone
Systems last better with the right care. Here’s what we suggest:
- Keep the service records with the warranty paperwork
- Make sure the condensate outlet can drain
- Clear leaves and debris from around the outdoor unit
For systems that need them, the leak check and its result go on record, and the next check is due within the period the rules set. We can book it in ahead of time.
Act on the early signs. A new noise, a faint smell or a drip is easier to deal with early than once the system has stopped.
From one of our customers
“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.”
