Air conditioning in Theydon Bois
We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. A lot of the calls we get from Theydon Bois are about one room that’s too hot to sleep or work in. That is normally a single wall-mounted split, from £1,200 + VAT.
A typical install in Theydon Bois is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
Homes around Theydon Bois are mostly houses, many with gardens, which usually leaves room for an outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Theydon Bois: your questions answered
Is Theydon Bois within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Can you do air conditioning in Theydon Bois?
Yes. Theydon Bois is one of the places we cover. Just ring 07833 053749 or fill in the contact form with a few details.
Can the outdoor unit go on a roof or at ground level?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Which type of system should I choose?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Is there a survey before the work?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
How long does it take to fit air conditioning?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote so there are no surprises.
What happens if it’s left?
Fans and portables move warm air around rather than removing it. A properly installed split moves heat outside, keeps the noisy parts out of the room and most of the time heats too, so it earns its keep all year. A system that’s left with a fault, or without a service, usually costs more to run.
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before we start, and the quote sets out the VAT.

The process
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 photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes about a day for a single-room system, longer for multi-room and ducted systems. Because we plan from pictures or a survey, a job in Theydon Bois can normally be finished in one visit.
- We survey the property, or work from your photos for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Getting ready for the visit
- Tell us about parking and loading
- Dig out any previous service or F-Gas records
- Clear access to the fuse board
