Air con installers in Sibley's Green
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. Air con, air conditioning, a split system: whatever you call it, in Sibley's Green it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
In a village like Sibley's Green, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it, and the outdoor unit position is chosen to suit the building.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

What air conditioning can’t fix
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Stuffy rooms that need fresh air rather than cooling
- Problems with a gas boiler or the radiators
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)

What an install looks like in Sibley's Green
About 80% of households live in detached or semi-detached houses, according to the 2021 Census. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
A loft bedroom or a glazed extension is often the room that prompts the first call. About 1.9 miles west stands Horham Hall. Listed homes in any area need consent first, so tell us if yours is one.

The process
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Seeing the property in pictures first means the trip to Sibley's Green can be planned properly.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where the consumer unit is
- Arrange for someone to be there to let us in
Ask for a quote
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Sibley's Green: your questions answered
Do you cover Sibley's Green for air conditioning?
Yes, Sibley's Green is within the area we cover. Get in touch with the details and we reply the same working day.
Can I fit air conditioning in Sibley's Green without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Sibley's Green holds about 8 listed buildings and structures. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Sibley's Green, normally Uttlesford council) when it matters.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We will tell you what to check before we fit it.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking and we’ll gladly show you ours.
Let and managed properties
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.

Leave it or put it right?
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Getting the date in early helps for a place like Sibley's Green.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, phone us on 07833 053749 or use the quote form and we will give you an honest view and a fixed price.
