How much does it cost to replace air conditioning in Heston?
Budget roughly £2,095–£5,695 per indoor unit ex VAT in Heston. For a typical job — replacing a 3–4 unit system, re-using sound pipework — expect £7,595–£18,550 plus VAT. The fixed price follows a free survey.
Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.
Working in Heston
Heston sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
That includes premises in TW5 and the surrounding districts. We also work in nearby Hounslow, Isleworth and Southall. In Heston, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
What the job covers
- Condition survey of the existing system
- Pipework re-use assessment, flushing where suitable
- Removal and disposal of old equipment
- Installation of new efficient units
- Commissioning and new F-gas records

Before you book in Heston
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Working hours
Most Heston businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Typical premises in Heston
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
