Unit-based pricing

Our prices for commercial air conditioning are based on the number of pieces of equipment you’d like us to maintain.

The cheapest price is for two units (£129 excl VAT) – that’s the minimum you’ll have, as there’ll be one internal air conditioning unit and one external one.

Benefits of a regular service

Annual services are recommended

Annual servicing should help to keep your business’ air conditioning system running smoothly and efficiently. This can:

  • Increase the life of your air conditioning system
  • Reduce running costs
  • Ensure warranties remain valid
  • Keep your staff and customers comfortable
