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.
Energy or Heat Recovery Ventilators (ERVs and HRVs) replace stale, polluted indoor air with a continuous supply of fresh outdoor air, helping improve moisture control, reduce odors, and support healthier indoor environments. ERVs transfer both heat and humidity to keep your home balanced, while HRVs focus on heat recovery and can connect directly to your existing forced-air ductwork so both systems operate together for efficient whole-home ventilation. By improving air circulation and reducing strain on your equipment, these systems help extend the life of your HVAC system, reduce cooking, bathroom, and pet odors, remove indoor toxins through filtration, and boost overall energy efficiency in your home or building.
Fresh, Balanced Ventilation for Healthier Homes & Buildings
ERV (Energy Recovery Ventilator) and HRV (Heat Recovery Ventilator) systems bring a continuous supply of clean, fresh outdoor air into your home while exhausting stale indoor air — all with minimal energy loss. These units recover heat, moisture, or both from the outgoing air stream, helping improve indoor air quality, control humidity, and support more efficient heating and cooling. At HVACDirect.com, we offer everything from compact multi-port units and through-the-wall spot ventilators to full-size whole-home and commercial systems. Every model is selected for performance, reliability, and long-term energy savings, ensuring your home or building gets ventilation that actually makes a difference.
If your space is tightly built, experiences humidity problems, or struggles with stale or stuffy air, an ERV/HRV is an essential upgrade. These systems deliver continuous, balanced ventilation — without the energy penalties of older fresh-air methods. They help maintain healthier indoor air, reduce pollutants, improve comfort, and support your HVAC system year-round. In short, they give you clean, conditioned air without wasting energy.

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
