About our air conditioning in Great Gaddesden
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. When someone in Great Gaddesden asks us for air con, the first questions are typically price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Where the outdoor unit goes decides how quiet and tidy the job is: we balance airflow, noise, the pipe run and access for future servicing.
Around Great Gaddesden, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
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, as a manufacturer or a future engineer may ask to see them.

Questions from Great Gaddesden
Do I need planning permission for air conditioning in Great Gaddesden?
It comes down to the building and the spot chosen for the outdoor unit. The Great Gaddesden Conservation Area is close to the centre of Great Gaddesden. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the planning department at Dacorum council, normally the authority for Great Gaddesden.
Is Great Gaddesden within the area you cover?
Yes. Great Gaddesden is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent, and we check the options on the survey. This is general information, not legal advice.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Which manufacturers do you install and repair?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
What we do, step by step
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer, and we tidy up before we leave. Photos of the room and the outside of the property help us plan a visit to Great Gaddesden.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Dig out any previous service or F-Gas records
- Keep pets out of the rooms we are working in

Let and managed properties
We also work for facilities teams in offices, schools and public buildings in Great Gaddesden and across Hertfordshire. Larger buildings can be done in stages to keep disruption down.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side, and the paperwork can go to both.
When something else is needed
We will always give you a straight diagnosis, so here’s what air conditioning will not do:
- Gas boiler or central heating faults (we don’t work on gas boilers)
- Building damp that has a structural cause
- A ventilation problem rather than a temperature problem
If you are not sure, just ring us on 07833 053749 or fill in the contact form and we will give you a straight answer before you book.

How we price air conditioning
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms, units or zones
- How far the pipework has to run, and where
- Access, including height, roofs and ladders
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before any work starts, and the quote sets out the VAT.
What we need to know
When you call or email, these details help:
- Your consumer unit or fuse board
- Any previous service or F-Gas records
- The outside wall, roof or yard where the outdoor unit sits or would go
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, call 07833 053749 or use the quote form.
Air conditioning in Great Gaddesden: local notes
About 73% of homes across Great Gaddesden and its surrounding area date from 1945 to 1972, according to Valuation Office Agency council tax records, and the 2021 Census found about 52% of households in terraced houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit.
Starting with one room is common, and the outdoor unit can be chosen with more rooms in mind. Living close to Church of St John the Baptist? Some older properties in parts like that are protected, and the survey finds out whether yours is.
