How much does it cost to replace air conditioning in Derby?
In Derby, guide prices run from about £1,595 to £4,350 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) usually comes to £5,850–£14,195 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.

Install and commission
New units are fitted, tested and commissioned with fresh records.
What to think about in Derby
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Leased premises
If your Derby premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
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.
Typical premises in Derby
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

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.
Should we replace R410A systems now?
Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.
