Air conditioning repair in Dunk's Green, done properly
Think of it as a doctor’s appointment for your air conditioning: diagnose the cause, treat it properly and sign it off when it’s working. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. If you are dealing with a flashing light and a system that won’t run and weak airflow from the indoor unit, we can sort it out.
We plan the trip to Dunk's Green so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

When air con fails in Dunk's Green
About 73% of households live in detached or semi-detached houses, according to Census 2021 figures. Let us know where the outdoor unit sits and whether a ladder is needed to reach it. In the mile around Dunk's Green’s centre, 5 conservation areas have been designated. Listed buildings are part of the picture here: about 16 within half a mile of the centre, such as Spoute House (grade II*). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
If a system fails at a school such as Plaxtol Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays. A photo of the error code and the unit’s rating label helps us plan the repair.

After we have gone
Think of this as the after-treatment advice, short and simple:
- Stop the unit if water is coming through a ceiling
- Clear debris away from the outdoor fan
- If there’s ice on the pipes, switch off and let it melt
Keep the filters clean and the outdoor unit clear after the repair: clean filters and a clear outdoor unit help the system run as it should. An annual service is the best way to catch the next fault before it stops the system.
Sensible use helps. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs, so it is not running flat out all day.
How it works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive. For a place like Dunk's Green, the timing is set with you and the travel is our side of the planning.
- We start with what the unit is doing, the make and any code.
- A diagnosis visit finds the cause with proper tests.
- We explain the cause in plain English and give you a fixed price.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear the space around the indoor unit, or where it will go
- Clear access to the fuse board
Ask for a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.
Advice
Also in Dunk's Green
Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or send an email.
Dunk's Green questions
Is Dunk's Green within the area you cover?
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.
Who do I call if my air conditioning fails in Dunk's Green out of hours?
Dunk's Green is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Dunk's Green and across Kent. Tell us who should receive the paperwork.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How long will you be on site?
We will confirm the time with your quote. As a guide, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find.
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 explain the options and quote for a new system if that is the answer.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
What air conditioning repair cannot fix
Not every problem is solved by air conditioning repair, and we’d rather say so up front. It does not solve:
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- A leak on an old R22 system
- A building problem rather than a system fault
If in doubt, call us on 07833 053749 or drop us a line and we will say what we think.
What we work on in Dunk's Green

What a customer said
“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.”
