How to Use Your HRV System Throughout the Year

When winter arrives, you're inclined to keep your door's homes and windows closed to keep cold air out. Then, when summer arrives, you'll probably keep your house closed up to keep the cool air in. The question is, when will you ever get rid of that stale air that remains trapped inside?

The reality is, you need to keep air circulating inside your home. And fortunately, that's where heat recovery ventilation systems, or HRV systems, come in. An HRV system is designed to replace your stale air indoors with fresh air from the outside. The system filters the air as it comes into your home. However, you do need to adjust this system's settings in different seasons and temperatures. Here's a rundown on how to use your HRV system throughout the year. Let's get started!

Fall/Winter Seasons

During the cooler months, your HRV system will allow you to control your home's air quality by removing odours and excess moisture, including condensation on your windows. As a general rule of thumb, you should set your system's dehumidistat to 25 percent to 50 percent depending on the temperature to keep condensation at bay. For instance, 50 percent is the maximum relative humidity you should have if the outdoor temperature is between -11 degrees Celsius to 18 degrees Celsius. Meanwhile, the humidity level should be 25 percent if the temperature is -30 degrees Celsius or below. Let's say that you have set your dehumidistat to a certain percentage in this range but you still notice moisture developing on your windows. In this situation, you should lower the setting to 5 percent. Keep doing this until no moisture develops on your windows. Also, whenever your HRV system is running, your furnace fan needs to be running, too. This will help you to further reduce condensation.

Spring/Summer Seasons

During the warm months, after your temperature has consistently remained higher than 18 degrees Celsius, you should set your system's dehumidistat to 100 percent. Alternatively, you should put it in the "off" position. If you begin to notice stuffiness or odours, feel free to turn on your HRV system with your bathroom fan on. Note, however, that if you run the system too often or continuously, this will cause hot, humid air from the outdoors to enter your home. As a result, your home's air conditioning system will run more frequently.
