Your air exchanger is most effective when run continuously. As long as it's on, your exchanger continuously filters out polluted air and brings in the clean stuff. If you turn your exchanger off, pollutants can build up in your indoor air.
The exchanger really should not run more than 20 minutes out of the hour as you are causing the furnace to have to run to heat the cold outside air you are drawing in. A better way to keep air fresh is to allow the exchanger to run 20 minutes but keep fan in on position on furnace to keep circulating air.
We recommend that you run your air exchanger for twenty minutes every hour, this will save you money on your heating.
Whenever the humidity exceeds the set level, the air exchanger will activate. It should be set around 40% to prevent mold growth. If your home is feeling dry, up to 55% should still be dry enough to prevent mold, but there will be more moisture in the air so out-of-the-way corners and windowsills might still get wet.
ASHRAE (formerly called the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends (in its Standard 62.2-2016, "Ventilation and Acceptable Indoor Air Quality in Residential Buildings") that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per ...
According to ASHRAE standard 62.1 (“Ventilation and Acceptable Indoor Air Quality in Residential Buildings”), homes need to have at least 0.35 air changes of outdoor air for indoor air per hour to maintain the quality of the indoor air.
An air exchanger should not make your house cold if it is functioning correctly. It is designed to exchange indoor air with outdoor air without significantly affecting the indoor temperature. If your house feels cold, it could be due to other factors or an issue with the system that needs to be addressed.
The cooler indoor air cools the heat exchanger core, which subsequently cools the incoming warm outdoor air. This results in less reliance on your air conditioning system, translating into lower energy usage.
The answer depends on your home's air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.
Air exchangers are quite durable, and can easily last 15-20 years. With proper maintenance, it's possible for air exchange units to last as long as 25 years.
The purpose of these air exchangers are to provide fresh air into the air system along with dehumidifying the existing air to ensure your home isn't creating mold growth. These systems also clean the existing stagnant air inside the home, allowing fresh air to move around freely.
The average whole house air filtration system costs $2,610, but it can range between $419 and $4,962, depending on the system size, filtration type, and the installation requirements.
Since the colder outdoor air is usually drier in the winter, an HRV can also help reduce excessive humidity in your home. We recommend setting your HRV to “minimum” or “vent”. However, the 20/40 setting is also good because it only runs the system for 20 minutes every hour.
Not only does it require electricity to run the air exchanger, but the air the exchanger brings into your house must be brought up to temperature. This may require that more electric is used to cool your building or that more fuel is also required for heating.
You'll want to check your air intake on a regular basis to remove any leaves, grass clippings, snow, or other detritus. Have the intake cleaned by a professional once every six years and after any major renovation. While you're at it, have them clean the nearby exhaust vent.

Regulate humidity: Air exchangers eliminate excess moisture, which helps keep your home comfortable—not too humid and not too dry.
Sometimes, the heat exchanger can get too hot and overheat. Your system can sense this overheating and will turn off the burners but keep the blower (fan) on to help the heat exchanger cool down. If this is your issue, you'll notice cool air blowing from your vents instead of heated air.
Air exchangers and the changing seasons
The relative humidity is at its highest, and it's often difficult to bring it down. Your air exchanger will come into play, working to lower the levels, which should be between 50 and 60 percent during the summer season.
The agency says it is “normal” for an air exchanger's motor to overheat, make noise and emit smoke when it reaches the end of its life, but the integrated safety device and current limiter shut off the power supply to prevent a fire. A total of 207,000 units of the affected products were sold in Canada.
To ensure that you home is well-ventilated and maintains good air quality, your HRV and ERV should run continuously. Many HRV fans can operate at low, medium, or high speeds depending on the ventilation requirements.
Basically it is on during the time of the year we don't or can't have a window/door open. I often say we turn it on when the furnace starts kicking out heat for the winter, but it is the same logic. We NEED to exchange air when our windows and doors open less.
An air exchanger constantly renews your indoor air, bringing several advantages: Significant improvements in air quality. Moisture evacuation. Superior ventilation.
Recognizing the signs that your air exchanger needs repair is crucial for maintaining a healthy and comfortable indoor environment. If you notice insufficient airflow, excessive condensation, lingering odors, noisy operation, or increased energy consumption, it's important to take action promptly.
