Your heat recovery ventilator(HRV) can help make your house a clean and healthy living environment, while at the same time keeping your heating bills down! But your HRV cannot do this on its own, it requires your help and it only takes seven simple steps to keep your HRV happy!

Here are the seven steps you should follow when cleaning your HRV:

  1. Turn Off Your HRV – turn off and unplug your HRV
  2. Clean or Replace Air Filters – Dirty or clogged filters can lower the HRV’s efficiency. Try to clean your filters at least every two months. To do this you simply remove the filter, clean with a vacuum cleaner, then soak and rinse the filter in warm water and dish soap.
  3. Check Outdoor Intake and Exhaust Hoods – Remove leaves, waste, or other obstructions that may be blocking the outside vents of your HRV. Without this airflow, your HRV won’t function properly. During winter make sure to clear any snow or frost buildup blocking outside vents.
  4. Inspect the Condensate Drain – Check to see if your HRV has a condensate drain, it will be a pipe or plastic tube coming out of the bottom of the unit. If it does, slowly pour about two litres of warm clean water in each drain pan inside the HRV to make sure it is flowing properly, if not just simply clean the drain.
  5. Clean the Heat Exchange Core – Check your HRV owner’s manual for instructions on cleaning the heat exchange core. Vacuuming the core and washing it with soap and water will help reduce dust that can build up inside the heat exchange core.
  6. Clean Grilles and Inspect the Ductwork – Once a year you should check the ductwork leading to and from your HRV. Remove and inspect the grilles covering the duct ends and vacuum inside the ducts. If a more thorough cleaning is required, call a certified service technician.
  7. Service the Fans – Remove the dirt that has accumulated on the fan blades by gently brushing them.

Your HRV should be serviced annually, much like your furnace. If you are not comfortable doing this yourself contact a certified service technician accredited by the Heating, Refrigeration and Air Conditioning Institute of Canada(HRAI).
