Air conditioning for homes and businesses in Marehill
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 talk you through it on the survey. Need an air conditioning installer for Marehill? We are based in East Grinstead and cover London and the South East, with a fixed-price quote before any work starts.
For a home in or near Marehill, an air-to-air system can cool in summer and heat in the cooler months, which suits garden rooms, lofts and extensions that the main heating struggles with.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Let and managed properties
Facilities teams in offices, schools and public buildings book us too across West Sussex. Larger buildings can be done in stages around the people who use them.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side, and the paperwork can go to both.
How the visit works
Every visit follows the same order: check the plan with you, protect the area, do the work, test what we have done and explain it all to you. The visit itself takes about a day for a single-room system, longer for multi-room and ducted systems. We agree a date with you and plan the visit to Marehill so we arrive with what’s needed.
- You send photos, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- It’s switched on, checked and handed over with its records.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Move furniture away from the wall where we will be working
- Dig out any previous service or F-Gas records
Getting a price
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

FAQs for Marehill
Do you cover smaller places like Marehill?
Yes. Marehill is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is air conditioning in Marehill permitted development?
It depends on the property. Historic England lists about 9 buildings and structures within half a mile of the centre of Marehill. 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 Marehill, usually Horsham council).
Can I use air conditioning to heat a room?
Usually, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
How do I know what size unit to get?
Sizing is done on the survey, room by room. An undersized unit never catches up, and an oversized one cycles and wastes energy and we explain the output we recommend.
Will you need to do electrical work?
Most of the time. We check your consumer unit on the survey and include any electrical work on the quote, and our NICEIC approval covers the installation and certificate.
Do you look at the job first?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
What owners can safely do
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or send an email.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

What affects the cost of air conditioning

- The brand, model and parts involved
- Whether it’s a one-off job or part of a maintenance contract
- The number of rooms, units or zones
Typical ranges are on our prices page, but your price depends on the job in front of us. For a fixed-price quote, ring 07833 053749 or email us, and we’ll talk you through it.

- Wide photos of the room or the existing unit
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.
