About our air conditioning in Cranham
Across Cranham, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. Air con, air conditioning, a split system: whatever you call it, in Cranham it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most single-room installs in Cranham are done in a day, while multi-split systems for several rooms can take longer.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

FAQs for Cranham
Can I have air conditioning in a flat in Cranham?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can I get a fixed-price quote for air conditioning in Cranham?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Who is responsible for leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Is Cranham in your area?
Yes. Cranham is part of the area we cover, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
Can you fit air conditioning in a leasehold flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
What you can do yourself, and what needs us
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
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.
What affects the cost of air conditioning
Jobs vary more than people expect. The main factors:
- The condition of any existing system
- Access, including height, roofs and ladders
- The equipment or parts the job needs
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 work begins.
Asking for a quote
Before you ask for a quote, gather:
- The postcode and whether it’s a home, flat or business
- A photo of the consumer unit with the cover closed
- The rating plate or label on any existing unit
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, ring 07833 053749 or drop us a line.
Air conditioning around Cranham
VOA council tax data date about 64% of homes across Cranham and its surrounding area to the post-war years, 1945 to 1972, and the 2021 Census found about 72% of households in detached or semi-detached houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you commute from Upminster station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.

Common problems we fix in Cranham
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window can’t close properly and the noisy part of the unit is in the room. A fixed split system puts the compressor outside.
Customers usually contact us when they notice something like this:
- A home office that warms up with screens and equipment
- A business premises that overheats in summer
- An ageing air conditioning system near the end of its life
About 3 miles north-west stands Hare Hall. Listed homes in any area need consent first, so tell us if yours is one.
Questions to ask before you book
- Exactly what the price includes, from supply and fitting to commissioning

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
