Heat Recovery Ventilation System (HRV)

A balanced ventilation system introduces fresh outdoor air into a home at the same rate that stale indoor air is exhausted from the home. Energy Recovery Ventilation (ERVs) and Heat Recovery Ventilation (HRVs) are similar devices in that both supply air to the home and exhaust sale air while recovering energy from the exhaust air in the process.

To Qualify For Rebates:

  • Home should be at or below 0.35 Natural Air Changes per Hour (NACH); if not, air sealing must be done before or in conjunction with the ventilation project
  • Equipment must be labeled ENERGY STAR®
  • A ventilation unit is required to deliver fresh (supply) air to the main living/work space and each bedroom/office, at a minimum

Residential Air Source Heat Pump

Heat pumps offer an energy-efficient alternative to furnaces and air conditioners for all climates. Like your refrigerator, heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. Because they transfer heat rather than generate heat, heat pumps can efficiently provide comfortable temperatures for your home year-round.

Ductless, mini-split-system heat pumps (mini-splits) make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions where extending or installing distribution ductwork is not feasible.

Like standard air-source heat pumps, mini-splits have two main components — an outdoor compressor/condenser and an indoor air-handling unit.

Air-Source Heat Pump Buying Guide
Ductless Mini-Split Heat Pumps

To Qualify For Rebates:

  • The home must be heated with electricity (see electrification rebates for switching from natural gas or propane)
  • Ducted: HSPF 9+; Ductless: HSPF 10+
  • The compressor must be variable capacity (three or more distinct operating speeds, or continuously variable)
  • Must be rated for cold climates and provide heat down to 5°F or lower
    • Recommend investing in hyper heat (Mitsubishi), low ambient or extra low-temperature heat pumps that heat to -13°F or lower
  • Load calculation required to the right-size outside unit and derate for high elevation
  • Must be used as the primary heat source in the home/building

Ductless mini-split systems can be an attractive and energy-efficient alternative to traditional air conditioning or evaporative cooling systems for many homeowners. Compared to conventional air conditioning, using a ductless mini-split cooling system can cut energy costs by 30 percent.

To Qualify For Rebates:

  • No mechanical cooling or replacing an existing central air conditioning system
  • SEER 18+

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20-30% of the air that moves through the duct system is lost to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set. More about duct sealing…

To Qualify for Rebates:

  • Repair any damaged and disconnected ducts and straighten out flexible ducts that are tangled or crushed
  • Seal all leaks and connections with mastic, metal tape, or an aerosol-based sealant (AEROSEAL product OK)
  • Seal all registers and grills tightly to the ducts
  • Before and after CFM measurements for ducts required
  • Insulate ducts in unconditioned areas (attics/crawlspaces/garages); duct insulation of an R-value of 6 or higher
  • Prove all requirements above by detailed documentation on invoice(s) and/or photos
  • Recommend evaluating your system’s supply & return air balance, to ensure air return ducts not too small
  • Recommend including a new filter as part of any duct system improvement
  • Recommend you ensure there is no back drafting by getting a CAZ (combustion appliance zone) safety test after
    ducts are sealed (if you have combustion appliances/equipment in your home-gas/propane)

Diagram of a heat pump clothes dryer

A heat pump dryer works as a closed-loop system by heating the air using it to remove moisture from the clothes. They are easy to install since they don’t require ventilation and can reduce energy use by at least 28% compared to standard dryers. They also dry laundry at low temperatures, so they are gentler on clothes. More…
