How we handle air conditioning servicing in Duncton
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 Duncton and the rest of West Sussex, whatever the make. If you are dealing with air conditioning that isn’t cooling as well as it did and a unit showing a fault code, we can sort it out.
Around Duncton, outdoor units sit close to gardens and greenery, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Refrigerant work is written up in the F-Gas records: 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.

Duncton questions
Do you cover smaller places like Duncton?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Can you do air conditioning servicing in Duncton?
Yes. Duncton is one of the places we cover. Get in touch with the details and we reply the same working day.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Do you offer air conditioning maintenance contracts?
We do, for one unit at home or many across a site. We fix the schedule, the scope and the cost with your quote and the servicing happens on time.
How regularly should I have my air conditioning serviced?
We recommend an annual service, with more visits for systems that run a lot. Check your manufacturer’s warranty conditions too, as they may set out servicing requirements.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.

What else we do in Duncton
Different systems, different jobs
Refrigerant performance and leak checks
tCO2e is the refrigerant charge in kg multiplied by its global warming potential, divided by 1,000. As an example, 3 kg of R32 comes to about 2.0 tCO2e, while 3 kg of R410A is about 6.3 tCO2e. We check the label on your system and tell you where it sits.
Indoor and outdoor coils
Outside, the coil gives off or picks up heat. Leaves, dirt and debris clog the fins and we clean it and make sure the air can flow.
What happens on the day
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes anything from an hour for a simple split system to most of a day for a larger installation. Seeing the property in photos first means the trip to Duncton can be planned properly.
- You tell us the brand, the number of indoor units and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
How to prepare
- Have the make and model of any existing unit to hand
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board
