Common problems we fix in Knotty Green
Everything that uses electricity in a room ends up as heat. A small office or a busy room can warm up fast with equipment and people in it, even on a mild day.
What we are most often called about:
- A portable unit with a hose out of the window
- A business premises that overheats in summer
- A loft conversion that’s too warm to use
About 4.6 miles south stands Cliveden. Listed homes in any area need consent first, so tell us if yours is one.
Questions to ask before you book
- The make and model of any parts or equipment being quoted
- How VAT is shown, and which rate applies
- Whether the manufacturer’s warranty depends on regular servicing
Leave it or put it right?
Putting up with another summer of portable units and fans rarely makes sense. A fixed system removes the heat to the outside, runs more quietly in the room and can normally heat as well, so it earns its keep all year. Small faults tend to grow, so it’s worth dealing with them early.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you will get one fixed price.

Knotty Green: your questions answered
Is Knotty Green in your area for air conditioning?
Yes. Knotty Green is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I fit air conditioning in Knotty Green without planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 5 listed entries sit within 0.5 miles of central Knotty Green. 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 planning department at Buckinghamshire council, usually the authority for Knotty Green when it matters.
How do you size the system?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Can I do the refrigerant work 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 it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
The process
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. Pictures of the space and where the outdoor unit could go let us plan the work in Knotty Green.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Plan for pets to be kept clear during the visit
- Let us know where we can park and unload

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep to the service interval the manufacturer recommends
- Leave space around the outdoor unit
- Close windows and doors while the system is cooling
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Set it and leave it. A moderate set temperature cools the room just as well as the lowest one, without the waste, and close windows and doors while it’s cooling.
