About our air conditioning repair in Marston
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 air conditioning running but not cooling and frost on the pipework, we can help.
We plan the trip to Marston so the repair can be finished in one visit where possible, though some parts have to be ordered from the manufacturer.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Common questions in Marston
Is there an emergency air con repair line for Marston?
The emergency line is open around the clock, and Marston is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you cover smaller places like Marston?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first, and if it’s clean, the system needs a diagnosis.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Why is my air conditioning leaking water?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Turn the system off to stop the water and give us a call.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Leave it or put it right?
Small faults rarely stay small. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should, so getting it looked at early typically means a simpler repair. Planning ahead for a job in Marston means we can bring everything needed.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.

What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Work in Marston is booked in advance at a time that suits you.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- You get a plain explanation of the fault and a fixed price for putting it right.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- Finally the system is tested in operation and you get a note of the fault and the fix.
How to prepare
- Arrange for someone to be there to let us in
- Let us know where we can park and unload
- Mention any managing agent or landlord rules we need to follow

When air con fails in Marston
Roughly a third of a mile or less from central Marston, you reach the Marston Conservation Area. In the mile around Marston’s centre, 2 conservation areas have been designated. On the National Heritage List, around 22 entries fall within 0.5 miles of the middle of Marston; Church of St Nicholas (grade I) is one. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be. About 42% of homes in and around Marston date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 63% of households live in detached or semi-detached houses, according to the 2021 Census. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
Before you call, note what the unit is doing and any code on the controller.

Aftercare tips
Every system needs looking after, and most of it is easy. A few tips:
- Turn the system off if it’s dripping water
- Only let an F-Gas qualified engineer work on the refrigerant
- Keep the outdoor unit clear of leaves and clutter
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. Parts lead times depend on the supplier and we will keep you updated.
Book an annual service. The engineer cleans what you cannot reach and picks up problems before they cause a breakdown, which is far simpler than an emergency repair.
Signs you need air conditioning repair in Marston
Leaks tend to start where pipes are joined: 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.
It’s time to call us if you are dealing with:
- A flashing light and a system that will not run
- A system that will not switch on
- A noisy indoor or outdoor unit
When cooling fails at a school like St Nicholas Primary School, we can time non-urgent repair work around lessons.
