How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Everything the job in Liss needs is worked out beforehand.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- 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.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Unlock any gate, garage or side passage we need
- Clear the space around the indoor unit, or where it will go
- Make sure someone can let us in at the agreed time

Air conditioning for homes and businesses in Liss
Single-room systems are typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, and commercial VRF systems are priced after a survey. When someone in Liss asks us for air con, the first questions are normally price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Planning permission isn’t 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.
Outdoor units around Liss often sit on the ground or a low wall bracket at the back of the house, where it’s out of sight from the road and easy to service.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What owners can safely do
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
What else we do in Liss
Pricing air conditioning in Liss
The quote reflects the job in front of us. We take into account:
- Whether the existing supply is suitable
- Whether it’s a simple split or a larger system
- How many units are involved
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
Before you get in touch
What to send for a quote:
- Where the property is and what kind of building it is
- Photos showing the indoor unit and the space around it
- A close-up of the unit’s label showing the model number
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Common questions in Liss
Is Liss in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Liss is part of that. Get in touch with the details and we reply the same working day.
Do I need planning permission for air conditioning in Liss?
That depends on the building and where the outdoor unit goes. The Liss Conservation Area is close to the centre of Liss. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at East Hampshire council, typically the authority for Liss.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we will gladly show you ours.
How quickly will you reply?
You will hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How much is air conditioning for one room?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
How long does air conditioning installation take?
Allow anything from a day for one room to several days for a multi-room or ducted system. We confirm the time when we quote so there are no surprises.
Aftercare tips
Every system needs looking after, and most of it is easy. Our tips:
- Do not cover or box in the outdoor unit
- Flag any change in how the system sounds or performs
- Keep the room closed while it runs
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.
Homes in Liss and air conditioning
About 71% of households live in detached or semi-detached houses, according to the last census (2021). Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
Around Church of St Mary, a quick check of the listing and conservation maps is part of planning any install. If you commute from Liss station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed.
