Heating
Explore equipment that warms homes, workplaces and larger facilities—from traditional furnaces and boilers to modern heat pumps.
Heat pumps
Move heat between indoors and outdoors to heat and cool a building. Air-source systems can serve existing ducts or a ductless indoor unit.
Explore collection ↗HEATINGFurnaces
Heat air and distribute it through ducts. Gas and electric models have different operating costs and installation needs.
Explore collection ↗HEATINGBoilers
Heat water for radiators, baseboards, or radiant floors. They do not provide cooling on their own.
Explore collection ↗HEATINGRadiant heating
Deliver warmth through floors or other surfaces using water or electric elements.
Explore collection ↗HEATINGBaseboard heaters
Provide room-by-room heating with electric resistance or hot-water circulation.
Explore collection ↗HEATINGUnit heaters
Warm garages, workshops, and commercial spaces using a fan and a fuel or electric heat source.
Explore collection ↗Ventilation
Understand how fresh air is supplied, stale air is removed and indoor pollutants are managed.
Exhaust fans
Remove moisture, odors, or pollutants from a specific room.
Explore collection ↗VENTILATIONWhole-house ventilation
Bring in outdoor air and remove stale indoor air using a planned ventilation strategy.
Explore collection ↗VENTILATIONHeat recovery ventilators
Exchange indoor and outdoor air while transferring some heat between the airstreams.
Explore collection ↗VENTILATIONEnergy recovery ventilators
Exchange fresh and stale air while transferring some heat and moisture.
Explore collection ↗VENTILATIONAir ducts
Carry conditioned air to rooms and return it to the system.
Explore collection ↗AIR QUALITYAir purifiers
Filter particles from room air or from a central HVAC system.
Explore collection ↗Air conditioning
Compare cooling equipment for one room, an entire home or a commercial building.
Central air conditioners
Use an outdoor unit and indoor coil to cool air delivered through ducts.
Explore collection ↗COOLINGDuctless mini-splits
Connect an outdoor unit to one or more indoor units for targeted cooling; heat-pump models also heat.
Explore collection ↗COOLINGWindow air conditioners
A single unit sits in a compatible window and cools one room.
Explore collection ↗COOLINGPortable air conditioners
A movable room unit exhausts warm air through a window kit.
Explore collection ↗COOLINGPackaged HVAC units
House heating and cooling components in one outdoor cabinet.
