Questions from Langley
Is Langley within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Who do I call if my air conditioning fails in Langley out of hours?
Yes: ring the emergency line, day or night, from anywhere in Langley. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
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 can tell you which band your system falls into.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
What can I do with an old R22 system?
R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak typically means replacement. We will set out the options and quote for a replacement where it makes sense.
My system uses R410A. Can it still be repaired?
Yes, repairs and recharges on existing R410A systems remain legal. As the GB phase-down continues, R410A is getting harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement.
How we handle air conditioning repair in Langley
Think of it as a doctor’s appointment for your air conditioning: diagnose the cause, treat it properly and sign it off when it’s working. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. We are often asked to deal with a fault code on the display and water leaking from the unit or through the ceiling, on heat pumps, multi-split systems and ducted systems.
In a place like Langley, repairs are typically for home systems and the odd shop or office. What you tell us about the fault shapes the visit, so describe what it’s doing and send a photo of any error code.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Signs you need air conditioning repair in Langley
Water dripping from an indoor unit is typically about the condensate. A blocked or kinked drain, a failed pump or a unit that isn’t level are the usual causes, while ice that forms on the coil and then melts can also cause drips.
The things we’re asked about most are:
- Air conditioning running but not cooling
- A flashing light and a system that won’t run
- Poor airflow even with clean filters
For a school like The Langley Academy Primary, urgent repairs can be booked straight away and bigger work in the holidays.
Questions to ask before booking
- Why the equipment they’re quoting suits the job
- Whether anyone has checked the property or the system first
- Whether the manufacturer’s warranty depends on regular servicing
How it works
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes anything from an hour or so to a full day, depending on the fault and the parts. Tell us about any gates or steps at your property near Langley when you book.
- We start with what the unit is doing, the make and any code.
- A diagnosis visit finds the cause with proper tests.
- We explain the cause in plain English and give you a fixed price.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- We test the system in operation and leave you a note of the fault and the fix.
Before we arrive
- Unlock any gate, garage or side passage we need
- Keep pets and children away from the work area
- Tell us about any building rules, permits or sign-in
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.

What air conditioning repair can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Heat gains the system was never designed for
- A unit whose parts are no longer made (replacement may be the only option)
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
If in doubt, ring 07833 053749, or email if that’s easier and we will say what we think.
Parts of the system we cover
- VRF systems
- Heat pumps
- Multi-split systems
- Ducted systems
