Keeping the system healthy
After the visit, a few habits help:
- Tell us if the unit starts to leak, rattle or show a code
- Shut doors and windows when it’s on
- File the paperwork with the manual
We recommend an annual service, and some manufacturers make regular servicing a condition of their warranty. We can remind you when it’s due if you’d like.
Book an annual service. A service cleans what you can’t reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.
How we handle air conditioning in Theydon Garnon
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. People searching for “air con near me” in Theydon Garnon want two things: a sensible price and someone qualified. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Many installs in Theydon Garnon can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Villages like Theydon Garnon often have older houses and cottages, some of them listed. We check that first, because permitted development does not apply within the grounds of a listed building, and the outdoor unit position is chosen to suit the building.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

How we price air conditioning
You’ll get a fixed price before any work starts. It’s based on:
- Whether we need access equipment for high-level work
- The number of rooms, units or zones
- How far the pipework has to run, and where
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Before you get in touch
When you call or email, it’s useful to have:
- A photo of the consumer unit with the cover closed
- The rating plate or label on any existing unit
- The address and the type of property
Every quote starts with a look at the job, 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
Theydon Garnon: your questions answered
Can I fit air conditioning in Theydon Garnon without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Theydon Garnon holds about 15 listed buildings and structures. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with Epping Forest council, which is typically the planning authority for Theydon Garnon.
Is Theydon Garnon within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
How do I know what size unit to get?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy, so we explain why we have chosen a particular output.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking and we will gladly show you ours.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
Which type of system should I choose?
It depends on the rooms and the building. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. We recommend one on the survey and explain why.
