HRV / ERV Your HRV/ERV acts as the lungs of your home by letting fresh air in while sending stale air out. Request A Quote Make your home healthier Don’t compromise on the air quality of your home. An HRV (heat recovery ventilator) or ERV (energy recovery ventilator) system by Cross Heating & Air Conditioning will provide your home with fresh air while reducing your exposure to the lingering effects of dust, volatile organic compounds (VOC), and other interior pollutants. How does an HRV work? An HRV works in two steps: It sucks out stale, humid air from your house. As the air passes through the HRV, it warms the plates of the heat exchanger. It introduces clean, fresh, outdoor air into your home. As the air passes through the HRV, it’s warmed by the heat previously stored in the plates of the heat exchanger. This process continues cyclically, ensuring that your home is always filled with clean air. Why you need an HRV Every home needs an HRV air exchanger for the benefit of the home and the health of its occupants. Here’s why: Keeps air fresh Reduces harmful indoor pollutants Reduces energy bills and energy consumption Delivers a consistent climate in your home HRV vs ERV: What’s the Difference? The key difference between an HRV and an ERV is that an HRV transfers heat while an ERV transfers both heat and moisture. Both types of air exchangers allow the homeowner to control the air quality in their home (by replacing stale indoor air with fresh outdoor air) as opposed to relying on the often inadequate leaks in the home to provide ventilation. How does an ERV Work? An ERV works almost identically to an HRV but it includes an extra step: It transfers some of the moisture from the outgoing air into the incoming air, helping keep the humidity in your home at a constant level. Having an ERV will efficiently keep the humidity in your home down during the hot, humid summer months.
