Air conditioning servicing in Theydon Garnon, done properly
Servicing does not mean topping up refrigerant. The refrigerant circuit is sealed, so a system that is short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. Common call-outs are for drips or damp patches below an indoor unit and no service record for the last year or more, on air-to-air heat pumps, wall-mounted split systems and ducted systems.
In a village like Theydon Garnon, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Leave it or put it right?
A service costs a set price and fits around your diary. A breakdown arrives without warning, so a planned visit is the easier option. Waiting rarely makes an air conditioning problem smaller.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, phone us on 07833 053749 or fill in the contact form and we will give you an honest view and a fixed price.

- Emergency calls taken 24/7
- Fixed-price quotes after a survey or pictures

Servicing in Theydon Garnon: local notes
About 77% of households live in detached or semi-detached houses, according to the 2021 Census. Access to the outdoor unit is the one detail that most changes how a visit is planned. On the National Heritage List, around 15 entries fall within 0.5 miles of the middle of Theydon Garnon; Church of All Saints (grade I) is one. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
Spring is a good time for a service, before the system is needed for cooling. For a school like Theydon Bois Primary School, maintenance visits can be booked out of term.

What happens on the day
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. The visit itself takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. For a village like Theydon Garnon, tell us about narrow lanes, gates and parking when you book.
- First we take the details: brand, model if you have it, how many indoor units and anything that’s been bothering you.
- The system is run and checked before anything is opened up.
- Filters, coils and the condensate drain are cleaned and cleared.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- You get a service record, with anything that needs attention explained.
Getting ready for the visit
- Mention any roof access, ladders or high-level work
- Clear a path to the units and the space around them
- Plan for pets to be kept clear during the visit
Ask for a quote
The quickest way to a quote is to send pictures: 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 many jobs can be priced from that.
Advice
Questions from Theydon Garnon
How often should air conditioning in Theydon Garnon be serviced?
For most homes, once a year. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you cover Theydon Garnon for air conditioning servicing?
Yes. Theydon Garnon is one of the places we cover. Get in touch with the details and we reply the same working day.
When is an F-gas leak check required?
Under GOV.UK guidance, systems of 5 to under 50 tCO2e need a check at least every 12 months, and 50 to under 500 tCO2e every 6 months. With leak detection fitted, the interval can be doubled, and we can tell you where your system sits.
What’s included in an air conditioning service?
We clean the filters and coils, clear the condensate drain and check the fans. We also check the electrical connections, the controls and the refrigerant performance plus a leak check on systems that need one.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Do you have a 24/7 line?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will tell you what to do first.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.

What the work involves, system by system
Indoor and outdoor coils
The outdoor coil does the same job on the other side of the system. Leaves, dirt and debris clog the fins, so we clean it and clear the area around the unit.
Refrigerant performance and leak checks
We check how the refrigerant circuit is performing, using temperatures and pressures to see whether it’s working as it should. If the readings suggest gas has been lost, we explain what that means.
