  • What Is the Difference Between a Furnace and a Boiler?

    A furnace heats air and distributes it through ductwork and vents throughout the property. A boiler heats water and distributes warmth through radiators, baseboard heaters, or radiant floor systems. Both systems require regular maintenance to operate efficiently. Duct Mate Air Conditioning and Heating Inc. services both furnace and boiler heating systems.

  • How Long Do HVAC Systems Typically Last?

    The lifespan of an HVAC system may depend on the type of equipment, how well it has been maintained, and how frequently it operates.
