Air conditioning servicing for homes and businesses in Isleworth
People in Isleworth book a service for all sorts of reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. The same full set of checks applies whatever prompted the call. Typical jobs include a service that’s overdue and error codes or flashing lights on the indoor unit, across wall-mounted split systems, multi-split systems and ceiling cassettes.
Commercial systems in a London area like Isleworth may need F-gas leak checks as well as a service, depending on its refrigerant charge. We record the checks and tell you when the next one is due.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

How the job changes from property to property
Filters
A clogged filter cuts the airflow through the unit. That makes it harder for the system to reach the temperature you’ve set, which is why filters are always part of the service.
Maintenance contracts
A maintenance contract sets out the visits, what each covers and the price, fixed with your quote. It suits homes and businesses alike.
Air conditioning servicing around Isleworth
About 51% of households live in flats, according to the 2021 Census. If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. City dust and debris build up on London outdoor units, which is why servicing matters. The Isleworth Riverside Conservation Area lies close to the centre of Isleworth, within about a third of a mile. Draw a one-mile circle round the middle of Isleworth and it takes in 6 conservation areas. Listed buildings are part of the picture here: about 46 within half a mile of the centre, such as Syon Park Boathouse the Pavilion (grade I). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
For a school like St Mary's Catholic Primary School, maintenance visits can be booked out of term.

Isleworth questions
Does my air con in Isleworth need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Can you do air conditioning servicing in Isleworth?
Yes. Isleworth is one of the places we cover. Just call 07833 053749 with a few details.
Do you offer emergency call-outs?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Do you top up refrigerant during a service?
We check refrigerant performance on every service, but adding gas is separate work. If it’s low, a leak repair comes first and the regas follows with a fixed price for each step.
Do you offer air conditioning maintenance contracts?
Yes, for homes and businesses. The visits, what each covers and the price are agreed with your quote and the servicing happens on time.
Does the manufacturer’s warranty require regular servicing?
It depends on the brand. Some may have servicing conditions attached, so check the terms for your system. We can explain the terms, and each visit is recorded.
How the visit works
Every visit follows the same order: agree the plan on site, put the dust sheets down, do the work, check the system and talk you through it. The visit itself takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Photos of the room and where the outdoor unit could go let us plan most of a visit to Isleworth in advance.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- We run the system again and leave you a service record.
How to prepare
- Keep pets out of the rooms we’re working in
- Dig out any previous service or F-Gas records
- Clear the space around the indoor unit, or where it will go

“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.”
