There are many ways you can improve your home’s indoor air quality and its ventilation. One of the most useful is the installation of an energy recovery ventilator (ERV) or heat recovery ventilator (HRV), devices which allow fresh air into your house without it drastically changing the indoor temperatures and placing more stress on the AC or heater.
We usually talk about energy and heat recovery ventilators together, but they aren’t the exact same device. When people are looking for better home ventilation, they’re often curious about what’s different between the two. We’ll explain ERV vs. HRV below.
