What happens if it’s left?
Faults do not fix themselves. If the system is faulty now, it will be faulty in a heatwave, when you need it most, so it’s worth having it diagnosed while you can plan the repair. Getting the date in early helps for a place like Keyhaven.
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, call 07833 053749 or fill in the contact form, and we will talk you through it.

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes a single visit for many faults, while some repairs need a second visit once parts arrive. A note on how to find the property and where to park makes a visit to Keyhaven easier.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- At the property, readings and tests narrow the problem down to its cause.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
How to prepare
- Let us know if the building has a permit or sign-in process
- Arrange for someone to be there to let us in
- Have the make and model of any existing unit to hand

Rented and managed buildings
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. 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.
Your questions about air conditioning repair in Keyhaven
Is Keyhaven within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does sea air affect air conditioning in Keyhaven?
It can, as Keyhaven is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. Corrosion on the outdoor unit is one of the things we check when we diagnose a fault.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. A dirty filter is worth checking first, and if it’s clean, the system needs a diagnosis.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we’re happy to show ours.
Why does my air conditioning run but not cool?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which, then give you a fixed price to fix it.
Do you have a 24/7 line for breakdowns?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Call 07833 053749 and tell us the make, the symptoms and any error code and we will talk you through what happens next.
When it’s something else
We’d rather tell you now than sell you work that will not help, so these are the things it will not cover:
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- An R22 system that has lost its refrigerant
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
Not sure which it is? You can call us on 07833 053749 or email us and we’ll tell you honestly before you book.

Air conditioning repair in Keyhaven: the local picture
Keyhaven lies within about 1 mile of the sea. Coastal outdoor units can suffer from corroded coils and terminals, which can lead to poor cooling or trips. Census 2021 figures found about 71% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. The middle of Keyhaven is part of the Keyhaven Conservation Area. In the mile around Keyhaven’s centre, 2 conservation areas have been designated. About 8 listed entries lie within half a mile of central Keyhaven, Aubrey House (grade II) among them. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
The rating label on the unit gives the model number, which helps us bring the right parts. Schools such as Milford-on-Sea Church of England Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.
