Air conditioning for homes and businesses in Crosswater
Air conditioning is not only for summer: most modern splits heat too. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, and a well-chosen system can earn its keep all year round. Looking for air con installers near Crosswater? We’re based in East Grinstead and cover London and the South East, with a fixed-price quote before any work starts.
In a village like Crosswater, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it, and the outdoor unit position is chosen to suit the building.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Crosswater questions
Will you come out to Crosswater?
Yes. Crosswater 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.
How do I get a quote for air conditioning in Crosswater?
Start with a short message: the address, what you need and a picture or two. Where pictures are not enough, a survey comes first and the fixed-price quote follows.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Do I need planning permission?
Not always. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it usually comes up, and we tell you at the survey. This is general information, not legal advice.
Do you look at the job first?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
How the job changes from property to property
Multi-split systems
Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
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 the inspection and get the system ready for it.
What we do, step by step
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. If a lane or gateway near Crosswater is tight for a van, let us know and we will plan for it.
- First comes a site survey, or pictures and measurements for a straightforward job.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Have the make and model of any existing unit to hand
- Clear a path to the units and the space around them
- Let us know if the building has a permit or sign-in process
Ask for a quote
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, phone 07833 053749, or email if that’s easier.

What an install looks like in Crosswater
About 73% of households live in detached or semi-detached houses, according to the 2021 Census. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit. At about 38 miles from central London, Crosswater sits inside the area we cover across London and the South East.
Farnham Castle, about 4.9 miles north, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Homes near St John the Evangelist are a good example of where we look up the heritage status of the building before fixing anything to it.

Before you call an engineer
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749 or send an email.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
