Air conditioning repair in Lisson Grove
A symptom is only a clue: warm air, drips and error codes can each have several causes. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, which is why diagnosis comes first. If the problem is a unit that has lost refrigerant and a system that won’t switch on, we can help.
In a managed building in Lisson Grove, the repair may need booking through the agent or building manager, so let us know who needs to know we are coming. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
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. For any other brand, we explain the manufacturer’s terms on your quote.

How it works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes anything from an hour or so to a full day, depending on the fault and the parts. The more we can see beforehand, the smoother the visit to Lisson Grove will be.
- Diagnose: test the system until the cause is clear.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair doesn’t make sense, you’ll hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
- Tell us about access, such as roof hatches, high walls or locked plant areas
How to get a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, give us a ring on 07833 053749 or drop us a line.

Let and managed properties
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements and we’ll come back with a fixed-price quote.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
What happens if it’s left?
Refrigerant supply is changing. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy and we weigh that up when we advise you. Planning ahead in Lisson Grove means you choose the date, not the weather.
What you pay reflects the actual work. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before any work starts.

Do you need air conditioning repair in Lisson Grove?
Rattles, buzzes and grinding sounds tend to be mechanical. Worn fan bearings, loose panels, debris in the outdoor fan or pipework vibrating against the building are common and some point to a compressor problem.
If any of these sounds familiar, it’s worth a diagnosis:
- Poor airflow even with clean filters
- A system that keeps cutting out
- A unit that has lost refrigerant
If your system near London Marylebone station stops in a hot spell, our 24/7 line is open.
