Expert air conditioning for The Heath: diagnosis first, then a fixed-price quote, the work and written records. Ask us for a fixed-price quote.
- A loft room or top floor that bakes in summer
- An ageing air conditioning system near the end of its life
- Old electric heaters you’d like to replace with something more efficient
Owner checks or an engineer?
There are a few things you can safely do yourself: 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.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Air conditioning in The Heath, done properly
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. Every installation in The Heath begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
Sizing is where cheap installs go wrong: we look at the room’s size, windows, insulation and use before choosing a unit.
Homes around The Heath typically 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.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

FAQs for The Heath
Is air conditioning in The Heath permitted development?
That depends on the building and where the outdoor unit goes. Historic England lists about 12 buildings and structures within half a mile of the centre of The Heath. 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 local planning authority (for The Heath, typically North Hertfordshire council).
Can you do air conditioning in The Heath?
Yes. We work across London and the South East from our base in East Grinstead, and The Heath is part of that. Just give us a ring on 07833 053749 or use the quote form with a few details.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.

Common problems we fix in The Heath
Some people come to us for heating rather than cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, which means more heat out than electricity in. Most modern split systems work this way.
These are the situations we see most often:
- Commercial rooms that are too warm for staff
- Fans and portables that don’t keep up
- A room that’s unbearable on warm days
Around Church of St Mary, a quick check of the listing and conservation maps is part of planning any install.
What to look for in a quote
- If the figure could change on the day
- Who does the electrical work, and whether they can certify it
- Whether the quote shows VAT clearly
What affects the cost of air conditioning
Typical ranges are on our prices page, and your quote is built on your job. What we look at:
- What electrical work the job needs
- A single visit or a regular plan
- Which make and model is being fitted or worked on
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account and give you a fixed price before we start.
What to send for a quote
What to send for a quote:
- A close-up of the unit’s label showing the model number
- The fuse board and where it is in the property
- Any error code or flashing light on the display
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. Visits to The Heath are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We survey the property, or work from your photos for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- 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.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
How to prepare
- Let us know where we can park and unload
- Let us know where the consumer unit is
- Arrange for someone to be there to let us in

Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749, or email if that’s easier.
