Air conditioning repair for homes and businesses in Gustard Wood
Any repair we carry out in Gustard Wood starts the same way: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. Then we explain what’s wrong and give you a fixed price to put it right. Common call-outs are for a suspected refrigerant leak and ice on the pipework or the coil, on multi-split systems, wall-mounted split systems and ducted systems.
A visit to Gustard Wood is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Keeping the system healthy
A little care keeps the system in better shape. We recommend:
- Check the filter, the mode and the set temperature before calling us
- If the breaker trips twice, leave it off
- Switch the unit off if water is leaking from it
After a repair, the basics matter: clean filters every few weeks in heavy use and space around the outdoor unit. An annual service is the best way to catch the next fault before it stops the system.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.

Signs you need air conditioning repair in Gustard Wood
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Coils can corrode and leak too, and a slow leak can go unnoticed until the system stops cooling.
Reasons to give us a call include:
- A system that will not switch on
- Poor airflow even with clean filters
- A unit that has lost refrigerant
The make, model and error code are the most useful things to tell us.

Questions from Gustard Wood
Do you cover smaller places like Gustard Wood?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Can you do air conditioning repair in Gustard Wood?
Yes. We work across London and the South East from our base in East Grinstead, and Gustard Wood is part of that. Tell us a little about the job and we’ll take it from there.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
What can I do with an old R22 system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak usually means replacement. We’ll set out the options and quote for a replacement where it makes sense.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
For landlords and property managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side, and the paperwork can go to both.
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
How the visit works
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. For a place like Gustard Wood, the timing is set with you and the travel is our side of the planning.
- 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 doesn’t make sense, you will hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
How to prepare
- Let us know where the consumer unit is
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand
