What we do, step by step
You don’t 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. Before we leave, the area is tidied and we explain what we’ve done. Photos of the existing unit help with repairs and servicing in Nettleden.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- It’s switched on, checked and handed over with its records.
How to prepare
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading
Getting a price

Air conditioning in Nettleden
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, and the manufacturer’s warranty terms are set out on your quote. A lot of the calls we get from Nettleden are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
In a village like Nettleden, 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.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

FAQs for Nettleden
Is Nettleden within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do you cover Nettleden for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Nettleden is part of that. To start, call us on 07833 053749 with a few photos.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Will I need planning permission?
Not always. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it normally comes up, and we tell you at the survey. This is general information, not legal advice.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Air conditioning in Nettleden: local notes
The Valuation Office Agency’s council tax figures date about 73% of homes in Nettleden and the neighbourhoods around it to the post-war years, 1945 to 1972, and about 52% of households live in terraced houses, according to the last census (2021). We check the wall construction on homes of that age, as it decides how the pipework goes through. With a terrace, the back wall or an extension roof is normally the best place for the outdoor unit. The middle of Nettleden is part of the Nettleden Conservation Area. Draw a one-mile circle round the middle of Nettleden and it takes in 4 conservation areas. Historic England lists about 16 buildings and structures within half a mile of the centre of Nettleden, including Church of St Lawrence (grade II*). Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the local planning authority (usually Dacorum council) has the final say on what’s allowed.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.

Common problems we fix in Nettleden
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, so a bedroom or office under the roof can stay warm well into the night.
What we are most often called about:
- Rooms heated by plug-in heaters
- Bedrooms and offices that overheat in summer
- Rooms under the roof that stay hot into the night
Living close to Church of St Lawrence? Some older properties in parts like that are protected, and the survey finds out whether yours is.
What to look for in a quote

- What records you get at the end
- Which brand and model they’re proposing, and why

What else we do in Nettleden
Leave it or put it right?
The outdoor unit’s position is worth getting right first time. A good position keeps noise down and leaves room for servicing, and it can make a difference to planning. We agree it with you on the survey. For a village like Nettleden, booking ahead lets us plan the trip properly.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are not sure what’s needed, call 07833 053749 or use the quote form for straight advice and a fixed price.
