What they do

JAC Air Conditioning Ltd calls itself a family-run business. Its Sussex work runs from the Horsham office, on the 2nd Floor of the Afon Building on Worthing Road, while the head office and registered office are in Boston, Lincolnshire. Companies House shows it was incorporated on 9 August 2010, which is 16 years; the site says established in 2010 and started in West Sussex.

It installs wall-mounted, ceiling cassette, ducted and multi-split systems from Mitsubishi, Daikin, Fujitsu, Samsung and LG. It works for residential and commercial clients, offers servicing, repairs for all leading brands and a 24/7 call-out service, and is an authorised service partner for Ochsner heat pumps. It says its CITB-qualified engineers serve Sussex, Surrey and Lincolnshire.

There's a dedicated Brighton page saying it provides air conditioning and heat pump services to homes and businesses across Brighton.

Credentials

F-gas: verified on the REFCOM register ("JAC Air Conditioning Ltd", Boston, F-Gas tick). The site says it is fully F-gas certified and links a REFCOM certificate issued on 25 May 2025 and expiring on 25 May 2028; the certificate shows the Boston address and prints no certificate number.

The company is active at Companies House (number 07340189). It claims no manufacturer approval tier, MCS or TrustMark. It isn't listed on Quidos.

Prices and warranty

No prices published; ask for a written quote including the unit, installation, pipework and commissioning, and whether VAT is included. No warranty terms of its own are published. The site links a Mitsubishi Heavy Industries warranty document from a distributor, which isn't JAC's own warranty.

Good to know

  • The head office is in Boston, Lincolnshire, and its F-gas certificate names that address.
  • Brighton and Worthing appear in a long coverage list that also includes Surrey and Lincolnshire towns.
  • The brand list is "top manufacturers like" five names, so confirm the make before you agree a quote.
  • It services Ochsner heat pumps as an authorised partner.
  • Testimonials carry no dates.

Good fit if

  • 24/7 call-out for urgent faults
