As of February 2015, Bard heating parts are available for purchase online at retailers that specialize in HVAC replacement components, such as HVAC PLUS and Furnace Part Source. These companies carry a wide assortment of name-brand parts, including compressors, sensors and gaskets.
HVAC PLUS offers discount coupons worth up to 33 percent off for joining its rewards program and provides price quotes on parts within one hour of inquiry. Parts from Furnace Part Source are covered by a one-year manufacturer's warranty. HVAC PLUS offers a warranty on some parts, but its policy is unclear.
The official Bard website provides helpful product information, including wiring diagrams and installation and parts manuals. Product specifications are also available.
