- Uncertainty over the right type and size of system

What affects the cost of air conditioning
The diagnosis comes before the price. The main factors are:
- The size of the job
- Whether it’s a one-off job or part of a maintenance contract
- The electrical supply and whether a new circuit is needed
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.

Air conditioning for homes and businesses in Green Street
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. Need an air conditioning installer for Green Street? We are based in East Grinstead and cover London and the South East, with a fixed-price quote before any work starts.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
Homes around Green Street 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.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

What happens if it’s left?
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, and that is hard to put right later. Booking the survey early gives you time to weigh up the options. Dealing with it now is usually simpler than a breakdown later.
What you pay reflects the actual work. That’s why every job is looked at first, and the price is agreed before we start.
Why people in Green Street choose us
- An F-Gas certified company, as the law requires

What else we do in Green Street
Homes in Green Street and air conditioning
Green Street is about 14 miles from central London, well within the area we cover from our base in East Grinstead. Valuation Office Agency council tax records date about 57% of homes in the Green Street area to the post-war years, 1945 to 1972. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route.
Wyllyotts Manor (roughly 3.7 miles north-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Green Street: your questions answered
Can you do air conditioning in Green Street?
Yes. We work across London and the South East from our base in East Grinstead, and Green Street is part of that. To start, phone us on 07833 053749 or use the quote form with a few photos.
Will you come out to Green Street?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Will you need to do electrical work?
Most of the time, yes: a dedicated circuit is needed. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.
Can air conditioning heat my home as well?
In most cases, yes: modern splits are typically heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
Should I choose wall-mounted, ducted or cassette?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
What we’re called out for in Green Street
Everything that uses electricity in a room ends up as heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even when it isn’t especially hot outside.
Look out for these signs:
- Portable units that are noisy and barely cope
- A business premises that overheats in summer
- Working from home in a room that gets too warm
If your home is in one of the older streets near St Michael and All Angels Church, it’s worth checking whether it’s listed or in a conservation area before an install.
Before you book anyone
- If the quote is based on a survey, photos or a diagnosis
- What the manufacturer’s warranty covers and for how long
- What paperwork you’ll receive afterwards
The process
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. A few pictures help us make the most of a visit to Green Street.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Make sure someone can let us in at the agreed time
- Mention any roof access, ladders or high-level work
