How much does it cost to replace air conditioning in Windsor?

In Windsor, guide prices 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) usually comes to £6,850–£16,695 plus VAT. Your exact price is fixed in writing once we have surveyed.

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.

The steps for a project in Windsor

  1. Survey

    We record what is installed, its condition and refrigerant, and what can be re-used. For sites in Windsor we confirm access and parking beforehand.

  2. Plan the swap

    Removal and installation are scheduled to keep downtime short.

  3. Recover and remove

    Refrigerant is recovered into certified cylinders and the old units removed.

  4. Install and commission

    New units are fitted, tested and commissioned with fresh records.

What to think about in Windsor

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 Windsor 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.

Downtime

We schedule the swap to keep the space usable, often over a weekend.

Working hours

Most Windsor businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Typical premises in Windsor

  • Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
  • Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
  • Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

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.
