Air conditioning servicing in Hunston
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We carry out air conditioning servicing for homes and businesses in Hunston and the rest of West Sussex, for most leading brands. If the problem is error codes or flashing lights on the indoor unit and new noises from the indoor or outdoor unit, we can help.
Most systems around Hunston need servicing once a year, ideally in spring before the warm weather.
We are an F-Gas certified company, 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.

Aftercare tips
After the visit, a few habits help:
- Call about new noises or smells rather than waiting
- Read the warranty conditions for your brand
- Clear leaves and debris from around the outdoor unit
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. The visits and the price are fixed with your quote so you do not have to remember.
The single most useful thing you can do is keep the filters clean. Most indoor units have filters you can slide out and rinse, and the manual shows how.
How the visit works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. A note on how to find the property and where to park makes a visit to Hunston easier.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- The system is run and checked before anything is opened up.
- We clean the filters and coils and make sure the condensate drains away.
- Next come the terminals, the controller and the refrigerant side, with a leak check if the system’s size makes one a legal duty.
- You get a service record, with anything that needs attention explained.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Dig out any previous service or F-Gas records
- Clear a path to the units and the space around them
How to get a quote
The quickest way to a quote is to send photos: 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. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

How often do you service systems in Hunston?
Usually once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.

F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.

On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Let and managed properties
Running several properties is easier with one contractor. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
We also work for facilities teams in offices, schools and public buildings across West Sussex. Work can be phased by floor, zone or building around the people who use them.
