Managing agents and facilities teams in Cranford
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.
How we handle air conditioning in Cranford
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. People searching for “air con near me” in Cranford want two things: a sensible price and someone qualified. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Sizing is where cheap installs go wrong: the survey covers room size, glazing, insulation and how the room is used, so the unit is not too big or too small.
London homes in Cranford can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

After we have gone
To keep the system working properly:
- Book an annual service
- Keep the F-Gas records, commissioning details and warranty information together
- Shut doors and windows when it’s on
Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer so you know how to get the best from it.
Don’t ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are normally simpler.
Cranford questions
Do I need planning permission for air conditioning in Cranford?
That depends on the building and where the outdoor unit goes. There’s a conservation area, the Cranford Village Conservation Area, close to central Cranford. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Hounslow council, usually the authority for Cranford.
Can you do air conditioning in Cranford?
Yes, Cranford is within the area we cover. Tell us a little about the job and we will take it from there.
Who is responsible for leak checks?
Responsibility is shared between the operator, typically 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.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Which type of air conditioning is best?
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.
How much does air conditioning installation cost?
For one room, a split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
How it works
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Before a visit in Cranford, we ask where the van can stop and how we reach the outdoor unit.
- First comes a site survey, or photos and measurements for a straightforward job.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Make sure someone can let us in at the agreed time
- Mention any managing agent or landlord rules we need to follow
- Clear a path to the units and the space around them

Signs you need air conditioning in Cranford
Commercial spaces gain heat from people, equipment, lighting and glazing. Keeping staff and customers comfortable is typically what prompts the call, and some rooms need cooling for the equipment as much as the people.
These are the situations we see most often:
- Expensive direct electric heating
- An ageing air conditioning system near the end of its life
- Working from home in a room that gets too warm
About 2.6 miles east stands Osterley House. Listed homes in any area need consent first, so tell us if yours is one.
