- An ageing air conditioning system near the end of its life
- Bedrooms and offices that overheat in summer

How we price air conditioning
Before we fix a price, we need to know a few things. We check:
- How far the pipework has to run, and where
- Whether it’s a one-off job or part of a maintenance contract
- The size of the job
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we will talk you through it.
What we need to know
What to send for a quote:
- Your installation or service records
- Any error code or flashing light on the display
- The rating plate or label on any existing unit
The quickest way to a quote is to send photos: 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 many jobs can be priced from that.
Air conditioning in Fern, done properly
We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Every installation in Fern begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
A typical install in Fern 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.
Around Fern, many people choose a system that heats as well as cools, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what air conditioning won’t do:
- Gas boiler or central heating faults (we don’t work on gas boilers)
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
If in doubt, ring us on 07833 053749 or fill in the contact form and we will say what we think.

What else we do in Fern
How the visit works
Every visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, check the system and explain it all to you. On site, the work takes anything from a day for one room to several days for a multi-room or ducted system. Pictures of the space and where the outdoor unit could go let us plan the work in Fern.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the outdoor unit, or where it will go

Safe owner checks
Owners can handle the everyday basics: 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.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
What an install looks like in Fern
About 42% of homes across Fern and its surrounding area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 62% of households live in detached or semi-detached houses, according to Census 2021 figures. We check the wall construction on homes of that age, as it decides how the pipework goes through. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
Cliveden (roughly 2.7 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Homes near Church of St John the Baptist are a good example of where we look up the heritage status of the building before fixing anything to it.
Fern is about 2 miles north-east of Marlow, in Buckinghamshire. Whether you’re in the middle of Fern or further out, our engineers cover air conditioning, from a single room to a whole building. Across Buckinghamshire, we cover 263 places, Fern among them. Guildford is in our area too, around 25 miles away.
Our nearest recent job to Fern was on Church Street, Staines-upon-Thames (TW18), about 15 miles south-east: installing two LG wall-mounted units in the main office area and a single unit in the client meeting room. More about it

Fern: your questions answered
Is air conditioning in Fern permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Around 11 listed entries sit within 0.5 miles of central Fern. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Buckinghamshire council, normally the authority for Fern.
Can you do air conditioning in Fern?
Yes. Fern is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Which accreditations do you hold?
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.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
