Radiant Heating, Hydronic Heating & Boilers

John Owens Services has been involved with boilers and radiant heating installation and repair for 40 years – in fact, John Owens himself was very active in the installation of new boilers, radiant floor heating, and hydronic heating in the construction boom years. Our Fairfax heating company has performed seasonal maintenance on boilers and radiant systems for over 30 years. We continue to install and retrofit boiler and radiant heating systems in Fairfax and throughout Marin and Sonoma Counties.

Owning a boiler and radiant system is similar to owning a car. They are dynamic, fluid-filled, pressurized systems with many moving parts. Maintenance is vital to the long life of all boilers and radiant heating systems. Annual boiler maintenance is the key. Our well-stocked trucks are mobile warehouses so that we can promptly service your boiler and radiant heat needs.
