Air conditioning in Shermanbury
Any installation we do in Shermanbury follows the same process as everywhere else we work: a site survey, or photos for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. Air conditioning installation in Shermanbury starts with a site survey, then a fixed-price quote that names the make and model.
Planning permission is not usually needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we tell you at the survey if it applies.
Space outside is rarely the problem in a place like Shermanbury. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

For landlords and property managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.

Other services in Shermanbury
What the work involves, system by system
Wall-mounted split systems
A single-room split is typically £1,200–£2,200 + VAT, including supply, installation, commissioning and F-Gas documentation. Long pipe runs, difficult access and a new circuit affect where your job sits in the range.
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill, and keep it as short and neat as the building allows.
Looking after your system
Aftercare is straightforward, and it helps at the next service:
- Book an annual service
- Let filters dry fully before you put them back
- Wash or vacuum the filters as the manual describes
If anything is not right after we’ve gone, call us on the same number. Let us know what’s happening and any error code, and we will talk it through with you.
Give the outdoor unit room to breathe. Anything piled against it, from leaves to garden furniture, reduces the airflow, and the system has to work harder as a result.
What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. If a lane or gateway near Shermanbury is tight for a van, let us know and we’ll plan for it.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- 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
- Tell us about parking and loading
- Name a contact who can meet us at the agreed time

About 74% of households live in detached or semi-detached houses, according to Census 2021 figures. 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.
Living close to The Parish Church of St Giles? Some older properties in parts like that are protected, and the survey finds out whether yours is. Bedrooms under the roof and rooms with big sunny windows are usually the first to overheat, so they’re the usual place to start.

Your questions about air conditioning in Shermanbury
Is Shermanbury within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Do I need planning permission for air conditioning in Shermanbury?
That depends on the building and where the outdoor unit goes. Historic England lists about 6 buildings and structures within half a mile of the centre of Shermanbury. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the local planning authority (for Shermanbury, typically Horsham council).
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How much is air conditioning for one room?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Long pipe runs, difficult access, a new circuit and premium indoor units push the price up, while commercial systems are priced after a survey.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we’re happy to show ours.
How long will the 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. You get a fixed price before any work goes ahead.
A customer’s words
“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.”
