Managing agents and facilities teams in Guston
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. 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.
We also work for facilities teams in offices, schools and public buildings in Guston and across Kent. Larger buildings can be done in stages around the people who use them.
About our air conditioning repair in Guston
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 doesn’t matter who installed it, so tell us the make and model if you know it. We’re often asked to deal with a unit blowing warm air and ice on the pipework or the coil, across heat pumps, ducted systems and ceiling cassettes.
Outdoor units in a place like Guston can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
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, ready for the next service or a warranty query.

FAQs for Guston
Is there an emergency air con repair line for Guston?
Yes: ring the emergency line, day or night, from anywhere in Guston. Have the make, model and error code ready, and we will talk you through what happens next.
Does sea air affect air conditioning in Guston?
It can. Guston is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. We look for corroded coils, fixings and connections on coastal repairs.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and we hold it.
Do you provide F-Gas records?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
Do you need air conditioning repair in Guston?
When the fan runs but the air isn’t cold, there are some common causes: a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Testing tells us which.
What we’re most often called about:
- Poor airflow even with clean filters
- Rattling, buzzing or grinding noises
- A suspected refrigerant leak
A photo of the error code and the unit’s rating label helps us plan the repair.
What your quote should include
- If the figure could change on the day
- Proof of F-Gas company certification
- What records you get at the end
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A supply fault outside the property
- An R22 system that has lost its refrigerant
- A building problem rather than a system fault
If you’re not sure, just call us on 07833 053749 or use the quote form and we will give you a straight answer before you book.

What a repair looks like in Guston
The coast is only about 2 miles from Guston. Coastal outdoor units can suffer from corroded coils and terminals, which can lead to poor cooling or trips. About 51% of households live in terraced houses, according to Census 2021 figures. Terraced homes rarely have side access, so say whether we reach the back through the house, a garage or a rear lane. The middle of Guston is part of a conservation area. Church of St Martin of Tours, listed at grade II*, is one of roughly 3 protected buildings and structures in the half-mile around Guston’s centre. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
When cooling fails at a school like Duke of York's Royal Military School, we can time non-urgent repair work around lessons.

What we do, step by step
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes an hour or two to diagnose most faults, with the repair time depending on what we find, and we tidy up before we leave. If a lane or gateway near Guston is tight for a van, let us know and we will plan for it.
- We start with what the unit is doing, the make and any 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
- Let us know where we can park and unload
- Mention any managing agent or landlord rules we need to follow
- Arrange for someone to be there to let us in
