Air conditioning for homes and businesses in Hernhill
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. When someone in Hernhill asks us for air con, the first questions are usually price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Many installs in Hernhill can go ahead as permitted development, but listed buildings, conservation areas and flats often need consent first: we flag that at the survey.
Homes around Hernhill normally have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Signs you need air conditioning in Hernhill
Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, so it gives out more heat than the electricity it uses. Most modern split systems work this way.
Common reasons people call us are:
- A system on old refrigerant that is due for replacement
- Portable units that are noisy and barely cope
- Bedrooms and offices that overheat in summer
A loft bedroom or a glazed extension is often the room that prompts the first call.

What we do, step by step
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Photos of the room and the outside of the property help us plan a visit to Hernhill.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where the consumer unit is
- Move furniture away from the wall where we’ll be working

How we price air conditioning
A fixed price needs a few facts first. We check:
- What electrical work the job needs
- The equipment or parts the job needs
- The type of system, from a single split to a larger system
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, phone us on 07833 053749 or drop us a line, and we’ll talk you through it.
Helping us quote
There’s no need for technical detail. Just send:
- The outdoor side of the property, including any roof or flat area
- The rating plate or label on any existing unit
- Wide photos of the room or the existing unit
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price before any work starts.
Common questions in Hernhill
Is air conditioning in Hernhill permitted development?
The answer turns on the property and where the outdoor unit would sit. The Hernhill Conservation Area takes in the middle of Hernhill. 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 isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the planning department at Swale council, typically the authority for Hernhill.
Does sea air affect air conditioning in Hernhill?
It can. Hernhill is within about 3 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do I get paperwork after the visit?
Yes, on every job. 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.
Is Hernhill in your area?
Yes. Hernhill is part of the area we cover, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Air conditioning in Hernhill: local notes
At about 3 miles from the coast, Hernhill is close enough for sea air to matter. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we will tell you if the model you choose has that option. Valuation Office Agency council tax records put about 39% of homes in and around Hernhill before 1919, and Census 2021 figures found about 74% of households in detached or semi-detached houses. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
Homes near Church of St Michael are a good example of where we look up the heritage status of the building before fixing anything to it.

How the job changes from property to property
Ceiling cassettes
Cassettes need space above the ceiling and a route for the condensate, with a condensate pump where the drain can’t fall naturally. The survey confirms the void and the drain route.
Offices, shops and commercial rooms
Systems over 12 kW of effective rated output bring extra duties for the building, such as a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange and prepare for it.

What a customer said
“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.”
