How to know if heat-recovery and energy-recovery ventilation are right for homes in your territory

Key takeaways

  • Heat-recovery ventilation (HRV) and energy-recovery ventilation (ERV) systems can save energy, but only in the right climates.
  • HRV systems save more energy in cold, heating-dominant locations, and ERV systems are better for hot, humid zones.
  • The cost-effectiveness of HRV and ERV units depends on where they’re installed; whether the project is a retrofit or new construction; and the size, specification, and operation of the equipment.
  • Now is a good time to consider adding HRV and ERV systems to your energy-efficiency programs. More products are becoming available, and the airtightness of new construction makes new homes good candidates for the technology.
