Air conditioning across TW4: what to expect
Any installation we do in TW4 follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before any work starts and the paperwork is in your hands when we finish. Typical jobs include fans and portables that don’t keep up and rooms that get too hot to sleep or work in, across wall-mounted split systems, ceiling cassettes and VRF systems.
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 we take it from there. At the end, we tidy up and run through the work with you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
What you’ll pay
The cost depends on the type of system and how many units are involved, the access and the parts and time the job needs. You get a fixed price before any work starts, so there are no surprises.
What you get with us
- A fixed price before any work starts
- NICEIC approved for electrical work
- Listed on Checkatrade
- Emergency calls taken 24/7
Ask for a quote
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price so you know the cost before we begin.

Where we install in TW4
Across TW4, from Twickenham, Hounslow West and Cranford to the villages, homes range from older terraces and cottages to new estates and flats. We survey every property before we quote, then a fixed-price quote.
We reply to enquiries from TW4 the same working day, with a 24/7 emergency line for breakdowns.
Hounslow West: About 2.1 miles north-east stands Osterley House. Listed homes in any area need consent first, so tell us if yours is one. Living close to Church of St Paul? Some older properties in parts like that are protected, and the survey finds out whether yours is.
Fixed-price quotes for air conditioning in TW4
We quote each job individually. This is what makes a difference:
- The condition of any existing system
- The pipe route between the units
- What electrical work the job needs
- How many units are involved
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll go through it with you.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The make and model of the system, from the label
- A short video of any fault, such as a noise or a flashing light
- Any previous service or F-Gas records
- The postcode and whether it’s a home, flat or business
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 photos or a survey, the price is fixed. To start, phone us on 07833 053749, or email if that’s easier.
What you can do yourself, and what needs 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 write to us at info@aircondoctor.co.uk.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Different systems, different jobs
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 route from the outdoor unit to each room is the main variable.
Ceiling cassettes
Ceiling cassettes fit into the ceiling and push air out in several directions, which suits offices, shops and open-plan spaces.
What we’re called out for in TW4
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, so a bedroom or office under the roof can stay warm well into the night.
Keep an eye out for any of the following:
- Bedrooms and offices that overheat in summer
- Fans and portables that don’t keep up
- Expensive direct electric heating
- Commercial rooms that are too warm for staff
FAQs for TW4
How long does air conditioning installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and we hold it.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s 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.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
