Covering Rochester and nearby
Rochester has a compact centre of shops, cafés and offices, with business units on its outskirts. Gillingham is about 3 km away.
We work across Rochester's postcode districts, including ME1 and NE19. Nearby, we also cover Chatham (about 2 km), Strood (about 2 km) and Gillingham (about 3 km). Buildings across Kent range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Points to plan for in Rochester
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Access and parking
Town-centre jobs in Rochester often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Premises we work in around Rochester
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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.
Your questions answered
How much does it cost to replace air conditioning in Rochester?
Guide prices in Rochester run from about £1,895 to £5,095 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £6,850–£16,695 plus VAT. We fix the price in writing after a free survey.
Do you also cover Chatham, Strood and Gillingham?
Yes. Alongside Rochester, we also cover Chatham, Strood and Gillingham. Each has its own page with local guide prices.
Which postcodes do you cover in Rochester?
All of them, including ME1 and NE19. Give us your postcode when you enquire and we will confirm the visit details.
Will a new system be cheaper to run?
Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
