As you stroll through the myriad responsibilities of being a homeowner, you might find yourself in the curious realm of indoor air quality and ventilation systems.

We’ll explore the ins and outs of Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) and help you decide which ventilation system suits your home. So, join me as we journey through the world of HRVs and ERVs.

The Great ERV vs. HRV Conundrum: A Tale of Two Air Ventilators

Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) may seem like siblings separated at birth, but they possess distinct characteristics that set them apart beneath the surface.

Hot and Humid Climates: The ERV Advantage

Using an ERV is generally more energy-efficient in such climates than an HRV. While both systems increase energy usage, an ERV’s operation consumes comparatively less energy, making it the better choice for sultry locations.

Cold Climates: The HRV vs. ERV Dilemma

In colder climates, the choice between HRVs and ERVs is less clear-cut. Several factors come into play, including the leakiness of the building envelope, the ventilation rate, the size of the living space, and the occupants’ behavior.

Navigating Mixed Climates: A Balancing Act

The choice between HRVs and ERVs is even more nuanced in mixed climates. Ultimately, the best ventilation system for these climates will depend on individual circumstances and preferences.
