Air conditioning repair in Hayes, done properly
For breakdowns that cannot wait, there’s a 24/7 emergency line, from an overheating comms room to water leaking from a unit. Call 07833 053749 and tell us the make, the symptoms and any error code and we’ll talk you through what happens next. We’re often asked to deal with water dripping from the indoor unit and a unit that has lost refrigerant, on ceiling cassettes, VRF systems and ducted systems.
In a managed building in Hayes, the repair may need booking through the agent or building manager, so let us know who needs to know we’re coming. Roof access can need keys or permits, and we plan for that before we arrive.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

What we are called out for in Hayes
A unit that runs but does not cool has a few usual suspects: a blocked filter, the wrong mode or set temperature, an outdoor unit that can’t breathe, a failed sensor or board, or low refrigerant from a leak. Diagnosis narrows it down.
Keep an eye out for these signs:
- New noises from the system
- A fault code on the display
- A system that keeps cutting out
Shops and offices around Hayes & Harlington station often can’t wait for cooling to come back, which is what the 24/7 line is for.

The process

The work takes anything from an hour or so to a full day, depending on the fault and the parts. Photos of the room and where the outdoor unit could go let us plan most of a visit to Hayes in advance.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
How to prepare
- Clear access to the fuse board
- Mention any parking restrictions near the property
- Let us know if the building has a permit or sign-in process

Common questions in Hayes
Can you do air conditioning repair in Hayes?
Yes. Hayes is one of the places we cover. Tell us a little about the job and we will take it from there.
What’s the best way to get a price for air conditioning repair in Hayes?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
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.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
How long does the work take?
That depends on what’s involved, but in most cases it takes as long as the fault needs, from a quick fix to a return visit for parts. We will confirm it with the quote.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
System by system
VRF systems
VRF systems often hold enough refrigerant to need regular F-gas leak checks. Any leak we find and repair is recorded for the operator’s records.
Condensate drains and pumps
The condensate drain is behind most indoor unit leaks. Drains block with dirt and growth, pipes get kinked and pumps fail, and a unit that is not level can spill water too.
