Lennox HRV
Fresh air ventilation with heat recovery — ideal for Chicago winters
The Lennox HRV (Heat Recovery Ventilator) is the right choice for Chicago's cold climate. It exhausts stale indoor air while recovering up to 80%+ of its heat to pre-warm incoming fresh air — giving you continuous fresh air ventilation without the energy waste of simply opening a window.
- Recovers up to 80%+ of heat from outgoing stale air
- Brings in fresh outdoor air without the energy penalty
- Exhausts excess moisture — ideal for tight Chicago homes
- Integrates with existing HVAC ductwork
- Reduces heating costs compared to simple exhaust ventilation
- Improves indoor air quality year-round
Lennox ERV
Fresh air ventilation with heat and moisture recovery — year-round efficiency
The Lennox ERV (Energy Recovery Ventilator) transfers both heat and moisture between incoming and outgoing air streams. Unlike an HRV, it retains some indoor humidity in winter — making it a better choice for homes where dry indoor air is a concern during Chicago's heating season.
- Recovers both heat and moisture from outgoing air
- Maintains indoor humidity levels in winter
- Reduces cooling load in summer by pre-conditioning incoming air
- Integrates with existing HVAC ductwork
- Better choice when indoor humidity retention is a priority
- Improves indoor air quality year-round
Understanding Ventilation for Chicago Homes
Tighter Homes Need Mechanical Ventilation
Modern energy-efficient homes are built tight — which is great for efficiency but means stale air, CO2 buildup, and pollutants can accumulate without a mechanical ventilation system.
HRV vs ERV — Which Is Right for You?
In Chicago's cold climate, an HRV is typically the better choice because it exhausts excess moisture (reducing condensation and mold risk). An ERV is better when the home is very dry in winter and humidity retention is a priority.
Integrates With Your Existing System
Both HRV and ERV systems connect to your existing HVAC ductwork, using your furnace blower to distribute fresh air throughout the home.
