- Energy Recovery Ventilation
ERV, HRV & DOAS Systems
Modern tight homes need controlled ventilation. Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) bring in fresh outdoor air while recovering up to 80% of the energy from exhaust air—giving you healthy indoor air without sky-high utility bills.

Benefits
Why Energy Recovery Ventilation?
Modern homes are built tight for energy efficiency—but that means pollutants, moisture, and CO2 build up inside. ERV/HRV systems provide the solution.
Fresh Air, Efficient
Bring in 100% fresh outdoor air while recovering up to 80% of the energy you’ve already paid to heat or cool.
Healthier Indoor Air
Dilute indoor pollutants, VOCs, CO2, and odors with continuous fresh air exchange—without opening windows.
Lower Energy Bills
Energy recovery means your HVAC system works less. Many homeowners see 15-25% reduction in heating/cooling costs.
Code Compliant
Modern building codes require mechanical ventilation in tight homes. ERV/HRV systems meet ASHRAE 62.2 requirements.

Recommended
Energy Recovery Ventilators (ERV)
ERVs exchange both heat AND moisture between incoming and outgoing air streams. Perfect for Michigan’s humid summers, they prevent excess moisture from entering your home while still providing fresh air.
- Recovers 70-80% of energy from exhaust air
- Transfers both heat AND humidity
- Ideal for humid climates (Michigan summers)
- Prevents summer humidity infiltration
- Maintains balanced indoor humidity
Best for: Michigan homes, humid climate control
Heat Only
Heat Recovery Ventilators (HRV)
HRVs transfer heat between air streams but not moisture. Best for extremely cold, dry climates where you want to retain indoor humidity during winter months.
- Recovers 70-85% of heat energy
- Transfers heat only, not moisture
- Best for very cold, dry climates
- Helps retain winter humidity
- Lower cost than ERV systems
Best for: Extreme cold climates, dry winters
Premium
Dedicated Outdoor Air Systems (DOAS)
DOAS units condition 100% outdoor air before introducing it to your space. Combined with ERV technology, they provide superior indoor air quality for commercial and high-performance residential applications.
- 100% fresh outdoor air delivery
- Precise temperature & humidity control
- Decouples ventilation from space conditioning
- Ideal for commercial applications
- Meets ASHRAE 62.1 ventilation requirements
Best for: Commercial, multi-zone, high-performance
Applications
Who Needs ERV/HRV Systems?
New Construction
Modern, tight homes require mechanical ventilation. ERVs are often required by code and provide efficient fresh air.
Deep Energy Retrofits
When you upgrade insulation and seal air leaks, you need controlled ventilation to maintain air quality.
Allergy & Asthma Relief
Filtered fresh air helps dilute indoor allergens while HEPA filtration removes outdoor pollen before it enters.
Commercial Buildings
DOAS systems provide code-compliant ventilation air while allowing flexible zone-level comfort control.
