- Ice on the pipework or the coil
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side, and the paperwork can go to both.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
Air conditioning repair in Horsham, done properly
Wondering whether the fault is something simple? Check the filter, the mode, the set temperature and the remote’s batteries first, and if that does not fix it, call 07833 053749. We reply to enquiries the same working day. The work covers wall-mounted split systems, ducted systems and VRF systems, and common reasons people get in touch are an error code or flashing light on the unit and a suspected refrigerant leak.
For a shop or office in Horsham, a system that stops in a heatwave is a real problem. The emergency line is open 24/7, with repair call-outs from £75 + VAT.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What owners can safely do
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.

After we have gone
To keep the system working properly:
- Check the settings and the remote’s batteries first
- Keep the outdoor unit clear of leaves and clutter
- Turn it off and let ice clear before the visit
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind and point out anything else we spotted.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault, and early diagnosis normally means a smaller repair.
Horsham: your questions answered
What’s the best way to get a price for air conditioning repair in Horsham?
The easiest way is to phone us on 07833 053749 or drop us a line with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Do you cover Horsham for emergency air conditioning repairs?
The emergency line is open around the clock, and Horsham is one of the places it covers. 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. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Why is my air conditioning showing a fault code?
An error code points us in the right direction, but it isn’t the whole answer. Write down the code and turn the unit off if it has stopped, then call us on 07833 053749 or fill in the contact form.
Is it legal to repair an R410A system?
Yes. Any leak is repaired before recharging, and the work is recorded, and we tell you honestly whether a repair is worth it on an older system.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. 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 will work out which band applies to yours.
What happens on the day
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes a single visit for many faults, while some repairs need a second visit once parts arrive, and we tidy up before we leave. Shops and offices in Horsham don’t usually need to close for the work.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you will hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Sign off: prove it works and record the visit.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the building has a permit or sign-in process

Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

A customer’s words
“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.”
