Energy Recovery Ventilation (ERV) removes old/stale air (the pollutants contained in it) by replacing it with fresh air. It improves moisture control and improves order control in residential and commercial HVAC systems. An HRV can be installed to work with a forced-air system by being connected to the ducts, this way both systems can run simultaneously.
Benefits of ERV System
Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) are whole-home ventilation systems that exchange stale indoor air for fresh outdoor air while recovering energy from the exhaust stream. They improve indoor air quality, reduce humidity, and lower heating/cooling costs.
ERVs transfer both heat and moisture, helping to balance humidity in warm or humid climates. HRVs transfer only heat, making them ideal for colder, drier climates.
Choose an ERV if you live in a humid or mixed climate, and an HRV if you are in a colder region where indoor air tends to be dry.
Inspect filters every 3 months and clean or replace them at least every 6–12 months, depending on air quality and usage.
Yes. Most systems integrate easily with central HVAC setups to provide balanced ventilation alongside heating and cooling.
Energy recovery can reduce heating and cooling costs by 20–30% compared to standard exhaust ventilation, depending on local climate and system efficiency.
