Air con installers in How Green
The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. Most enquiries from How Green start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
In a village like How Green, many homes are older, and some are listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
Warranty periods vary by brand and by product. 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.

What an install looks like in How Green
The middle of How Green is part of a conservation area. On the National Heritage List, around 11 entries fall within 0.5 miles of the middle of How Green; Dairy Cottage at Hever Stud Farm (grade II) is one. Heritage protection changes what an install can involve, so the survey looks at your address first and tells you plainly whether consent is likely. About 23 miles out from central London, How Green is part of the South East area we work across.
Hever Castle, about 0.7 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. The work takes anything from a day for one room to several days for a multi-room or ducted system. A note on how to find the property and where to park makes a visit to How Green easier.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Arrange for someone to be there to let us in
- Plan for pets to be kept clear during the visit
- Let us know where we can park and unload
How to get a quote

Advice
Owner checks or an engineer?
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
How Green questions
Do you cover How Green for air conditioning?
We do: How Green falls inside our working area. Get in touch with the details and we reply the same working day.
Is How Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
Does air conditioning work as heating?
Usually, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Should I choose wall-mounted, ducted or cassette?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling, which we check on the survey.
How long does air conditioning installation take?
It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The survey tells us how long your installation will need, so you can plan around it.
How do you size the system?
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 and we explain the output we recommend.
What we’re called out for in How Green
Commercial spaces gain heat from people, equipment, lighting and glazing. Comfortable staff and customers are the usual reason businesses get in touch, and some rooms need cooling for the equipment as much as the people.
These are the situations we see most often:
- Expensive direct electric heating
- Bedrooms and offices that overheat in summer
- An office, shop or restaurant that is uncomfortable for staff and customers
If your home is in one of the older streets near Church of St Peter, it’s worth checking whether it’s listed or in a conservation area before an install.
Before booking anyone
- Which brand and model they’re proposing, and why
- What records you get at the end
- Whether the company is F-Gas certified, and whether you can check it
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what air conditioning will not do:
- Problems with a gas boiler or the radiators
- A building fabric problem such as single glazing or no loft insulation
- Stuffy rooms that need fresh air rather than cooling
If you are not sure, just give us a ring on 07833 053749, or email if that’s easier and we will give you a straight answer before booking.
