Lennox Indoor Air Quality Systems

How can I ventilate my home without losing energy?

The Healthy Climate® Collection includes ventilation products that make it possible to bring fresh outdoor air into the home, without leaving windows open. Heat-recovery ventilators (HRVs) and energy-recovery (or enthalpy-recovery) ventilators (ERVs) exchange stale, recirculated indoor air with fresher outside air, and no energy is wasted.

HRVs and ERVs are electronically powered units that circulate air throughout your home using the existing forced-air system or specially installed ducts. These units pump stale air out of your home and replace it with an equal volume of fresher outside air.

Generally recommended for colder climates, an HRV uses heat from the outgoing stale air to warm up fresher air coming into your home from outside. Ideal for climates with high outdoor humidity, an ERV is similar to an HRV, but it removes excess moisture from the air coming in from outside.
