Air conditioning specialists with standards that show
Knights Airconditioning Ltd is a professional, F-Gas certified company based in Stevenage. We design, install, service and repair air conditioning for homes and businesses across Hertfordshire.
Built on experience, trusted across Hertfordshire
Knights Airconditioning Ltd was built on a simple idea: that air conditioning should be installed and maintained by people who genuinely care about getting it right. Years of hands-on experience across domestic and commercial projects have shaped the way we work.
From our base in Stevenage, our skill card qualified engineers cover the whole of Hertfordshire. With 10 years specialising in residential installation, retrofitting, renovations and loft conversions, we also work on commercial installations and server rooms, always to full F-Gas standards.
We are F-Gas certified, fully insured and committed to a clear health and safety policy. More than that, we are the kind of team that cleans up properly, explains things clearly and picks up the phone when you need us.
