  • About us

    JCS Air Conditioning Services Ltd was formed by Jonathan Collis in early 2003 due to spiralling costs levied by larger building services companies. As a fully qualified air conditioning and refrigeration engineer, the company ethos is gained from the enjoyment and personal pride of providing high-quality work to appreciative clients who value a friendly ongoing business relationship. We are based in Devizes, Wiltshire.
