Common questions in Walham Green
Who do I call if my air conditioning fails in Walham Green out of hours?
Yes. Our 24/7 emergency line covers Walham Green. Have the make, model and error code ready, and we’ll talk you through what happens next.
How do I get a quote for air conditioning repair in Walham Green?
Start with a short message: the address, what you need and a picture or two. We reply the same working day, and the quote is fixed before any work starts.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How long will you be on site?
That depends on what’s involved, but most of the time it takes an hour or two to diagnose most faults, with the repair time depending on what we find. We will confirm it with the quote.
Air conditioning repair for homes and businesses in Walham Green
A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead, so you can decide with the facts in front of you. Typical jobs include ice on the pipework or the coil and a system that keeps cutting out, across multi-split systems, ducted systems and VRF systems.
London systems in Walham Green often run long hours in summer, and that is when faults show: weak cooling, water leaks, error codes or a unit that won’t start. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How it works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the room and where the outdoor unit could go let us plan most of a visit to Walham Green in advance.
- We start with what the unit is doing, the make and any code.
- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- It’s tested running, and the write-up is left with you.
How to prepare
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about any building rules, permits or sign-in

Whether it’s one property or many, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring 07833 053749 or email us.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
