Compare ERVs and HRVs to see which ventilation fits your climate, home airtightness, and humidity needs while saving energy and improving air quality.
ERV vs HRV: Which Ventilation System Is Better for Your Home? If you're deciding between an ERV (Energy Recovery Ventilator) and an HRV (Heat Recovery Ventilator), here's the quick breakdown: - HRVs: Best for cold, dry climates. They exchange heat but remove excess indoor moisture, helping prevent window condensation in winter. - ERVs: Ideal for hot, humid regions or very dry winters. They transfer both heat and moisture, balancing humidity levels inside your home. Both systems improve indoor air quality by replacing stale air with filtered outdoor air while conserving energy. Your choice depends on your climate, home construction, and indoor moisture needs.
