Homes around Gosmore usually have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Air conditioning around Gosmore
About 43% of homes in the Gosmore area date from 1945 to 1972, according to VOA council tax data, and Census 2021 figures found about 61% of households in detached or semi-detached houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Older streets near Church of St Ippolyts (church of England) may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. About 4.7 miles south-east stands Knebworth House. Listed homes in any area need consent first, so tell us if yours is one.

How it works
Each visit runs to the same pattern: agree the plan on site, protect the area, do the work, 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. If a lane or gateway near Gosmore is tight for a van, let us know and we will plan for it.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Preparing for the visit
- Move furniture away from the wall where we’ll be working
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it

FAQs for Gosmore
Do you cover Gosmore for air conditioning?
Yes, Gosmore is within the area we cover. Just call 07833 053749 or email us with a few details.
Can I fit air conditioning in Gosmore without planning permission?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Gosmore Conservation Area, close to central Gosmore. 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 North Hertfordshire council, typically the authority for Gosmore when it matters.
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 units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork and is fixed after a survey or from photos.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Do you have a 24/7 line?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- An installation that needs consent nobody has given yet
- Building damp that has a structural cause
If in doubt, call us on 07833 053749, or email if that’s easier and we will say what we think.
What the work covers
- Ceiling cassettes
- Multi-split systems
- VRF systems
- Ducted systems
- Wall-mounted split systems
- Air-to-air heat pumps
Managing agents and facilities teams in Gosmore
Running several properties is easier with one contractor. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.

How we price air conditioning
The price is fixed before any work begins. It takes into account:
- One-off work versus a regular service cycle
- The electrical supply and whether a new circuit is needed
- How far the pipework has to run, and where
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before any work starts.
What we need to know
Good photos often save a visit. The most useful are:
- Your consumer unit or fuse board
- The make and model of the system, from the label
- Your installation or service records
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
