Keep your Heat recovery ventilator running smoothly

Fresh air inside your house all year round and energy savings—these are just some of the benefits that a heat recovery ventilator (Heat recovery ventilator) can provide.




Your Heat recovery ventilator improves indoor air quality while saving energy by exhausting stale, humid air from your house and replacing it with fresh, outside air. For example, in the winter, your Heat recovery ventilator transfers heat from the outgoing stale air to the incoming cold fresh air before it enters your home so it reduces the energy your furnace needs to heat your house.


In the summer, your Heat recovery ventilator works the opposite way—it cools the incoming warm air down before it enters your home so it reduces the energy your air conditioner needs to keep your house cool.


To maintain ventilation efficiency, ensure your Heat recovery ventilator’s filters are cleaned at least every two months or as indicated on the manufacturer’s instructions. Before removing the filters, turn off the power to the Heat recovery ventilator at the control panel and unplug the unit from its electricity outlet. Filters in most new Heat recovery ventilator can be easily removed, cleaned with a vacuum cleaner and then washed with mild soap and water. Next, vacuum or brush out any accessible surfaces inside the Heat recovery ventilator itself. Check that the blades on both the supply and exhaust fans are clean as well. Any dust can be brushed and vacuumed out. Outside, check that both intake and exhaust hoods are functional and are not blocked or covered.


The heat exchange core should be cleaned at least once a year or as recommended by the manufacturer. If there is a condensation (drip) pan in the Heat recovery ventilator, clean it as well and pour a litre of water into the drain to check that the drain pipe is free-running. Also, clean the supply and exhaust air grilles located in rooms throughout the house. You can also vacuum any accessible sections of the ducts themselves.


Most motors in new Heat recovery ventilators are designed to run continuously without lubrication, but older models may require a few drops of proper motor lubricating oil in a designated oil intake. Check your manual for complete instructions.


It’s important to ensure that your Heat recovery ventilator brings in as much fresh air as it takes out stale air. To operate the way they are supposed to, the airflows into and out of Heat recovery ventilators need to be balanced, meaning the fresh air flow matches the exhaust flow. It’s advisable to have the Heat recovery ventilator airflows measured and balanced by a qualified contractor to ensure that it is operating properly. You could have a specialist service the Heat recovery ventilator every year at the same time that your furnace is being serviced to ensure the entire system is operating properly. Servicing should include an air balance test, cleaning and a check of the ductwork, outdoor hoods, controls and the operation of the Heat recovery ventilator.
