Customers normally contact us after spotting something like this:
- Air conditioning running but not cooling
- A fault code on the display
- A noisy indoor or outdoor unit

Air conditioning repair in Hayes
Refrigerant does not get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. We are often asked to deal with a flashing light and a system that won’t run and a unit blowing warm air, across ceiling cassettes, wall-mounted split systems and ducted systems.
In Hayes, as across London, air conditioning works hard in hot spells, and that is when faults show: weak cooling, water leaks, error codes or a unit that will not start. The error code on the display, the make and the model are the most useful things to send us.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Air conditioning repair in Hayes: the local picture
About 72% of homes in and around Hayes were built between the wars, according to VOA council tax data, and about 80% of households live in detached or semi-detached houses, according to Census 2021 figures. If the outdoor unit is high up or behind a locked gate, mention it when you book. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. The Bromley, Hayes and Keston Commons Conservation Area lies close to the centre of Hayes, within about a third of a mile. 3 conservation areas lie within a mile of central Hayes. About 5 listed entries lie within half a mile of central Hayes, The Rectory (grade II) among them. 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 Hawes Down Primary School, urgent repairs can be booked right away and bigger work in the holidays.

Common questions in Hayes
Do you cover Hayes for emergency air conditioning repairs?
Hayes is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
How do I get a quote for air conditioning repair in Hayes?
Send us photos of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.
Why is my air conditioning icing up?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and call 07833 053749 or use the quote form.
Why is my air conditioning leaking water?
Usually a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and ring us on 07833 053749 or email us.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you provide F-Gas records?
Yes. You get a written record of each visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Are you F-Gas certified?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.

What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes as long as the fault needs, from a quick fix to a return visit for parts. In a London area like Hayes, parking and access are worth sorting out before the day.
- We start with what the unit is doing, the make and any code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- 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.
- The system is run and checked, and you get a written note of the repair.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Plan for pets to be kept clear during the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Getting a price
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, ring us on 07833 053749 or fill in the contact form.

Different systems, different jobs
VRF systems
VRF systems often hold enough refrigerant to need regular F-gas leak checks. Leak repairs are written into the F-Gas records for the operator’s records.
Fans and compressors
The compressor is the heart of the system. Compressor faults can sometimes be caused by something else, such as an electrical fault or a refrigerant problem, so we test before condemning it. A failed compressor often raises the repair-or-replace question, and we give you both prices.
When something else is needed
It’s worth knowing the limits before booking:
- A supply fault outside the property
- A unit whose parts are no longer made (replacement may be the only option)
- A leak on an old R22 system
Not sure which it is? You can give us a ring on 07833 053749 or email us and we will tell you honestly before you book.
