Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) are whole home mechanical ventilation systems. They use a heat exchanger and a series of ducts and fans to blow stale air outside and bring filtered fresh air inside. Both systems reduce heat loss by transferring heat from the outgoing stale air to warm up the…

A combined system provides both radiant space heating and hot water heating for your home. Like air-to-water (hydronic) systems, combined systems are most suitable for new construction or for homes with an existing boiler and radiant heating system. Heating mode: Cooling mode is a reverse of heating mode:

An air-to-water (hydronic) heat pump system relies on heated and cooled water. Air-water systems are most suitable for new construction or for homes with an existing boiler and radiant heating system. Heating mode: Cooling mode:

A dual fuel central ducted heat pump distributes warm and cool air through ductwork in your walls, ceilings or floors. A single central thermostat controls the temperature. A back-up heat source helps during very cold weather. Heating mode: Cooling mode is a reverse of heating mode:

A mini-split heat pump has a single indoor head that is typically mounted on a wall. It serves a single room or open space and is controlled with a remote. Heating mode: Cooling mode is a reverse of heating mode:

A multi-split heat pump has two or more indoor heads in different rooms around the home. Each head has its own remote for temperature control. Heating mode:  Cooling mode is a reverse of heating mode:

A central ducted heat pump distributes warm and cool air through ductwork in your walls, ceilings or floors. A single central thermostat controls the temperature.  Heating mode: Cooling mode is a reverse of heating mode:

The Air Conditioning, Heating, and Refrigeration Institute (AHRI) certifies heat pump system efficiency. The AHRI number is a unique ID for heat pump and furnace components that were tested as one system. It is a rating of the efficiency of the complete system. If any component of your heat pump system changes, the system will have a…
