Air conditioning repair in Keymer
We repair air conditioning on all the main brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It does not matter who installed it, so tell us the make and model if you know it. If the problem is a unit that won’t start and a unit that has lost refrigerant, we can sort it out.
Outdoor units around Keymer often sit near hedges, trees and lawns, and leaves or grass cuttings on the coil are a common reason for poor cooling. We check the coil early on.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

The Keymer Conservation Area lies close to the centre of Keymer, within about a third of a mile. Historic England lists about 7 buildings and structures within half a mile of the centre of Keymer, including Ockley Manor (grade II*). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 42% of homes in Keymer and the neighbourhoods around it date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 77% of households in detached or semi-detached houses. A photo of the outdoor unit and its surroundings tells us what access the visit needs.

Keymer questions
Do you cover Keymer for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Keymer. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Keymer in your area for air conditioning repair?
Yes, Keymer is within the area we cover. Tell us a little about the job and we will take it from there.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
What causes water to leak from an air conditioning unit?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice that forms on the coil and melts can cause drips too. Switch the unit off and ring 07833 053749 or email us.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Note the code and switch the system off if it is not working, then call us on 07833 053749 or use the quote form.
How much is an air conditioning call-out?
A diagnosis call-out is from £75 + VAT. When we have found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
The process
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes anything from an hour or so to a full day, depending on the fault and the parts. We plan the visit to Keymer from the survey or your pictures.
- You tell us the symptoms, the make and any error 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.
- We test the system in operation and leave you a note of the fault and the fix.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
- Plan for pets to be kept clear during the visit
Ask for a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Advice
Honest limits
It’s worth knowing the limits before booking:

What affects the quote in Keymer
The survey or diagnosis tells us what the work involves. The main factors are:
- What state the existing equipment is in
- How far the pipework has to run, and where
- The equipment or parts the job needs
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so you know where you stand.
Asking for a quote
Good photos often save a visit. The most useful are:
- A short video of any fault, such as a noise or a flashing light
- Your installation or service records
- A close-up of the unit’s label showing the model number

When to call us in Keymer
Refrigerant leaks often start at joints: joints, valves and sections of pipe worn by vibration or damage. Corrosion on coils can also cause leaks over time, and a slow leak can go unnoticed until the system stops cooling.
These are the situations we see most often:
- Ice on the pipework or the coil
- Drips from the indoor unit
- A unit that will not start
For a school like The Windmills Junior School, urgent repairs can be booked right away and bigger work in the holidays.
What your quote should include
- How extra work would be agreed if they find something unexpected
- Whether anyone has checked the property or the system first
- Whether the company is F-Gas certified, and whether you can check it

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
