Do you have an HRV (Heat Recovery Ventilation) unit in your home? If so, it needs to be cleaned regularly to keep your home comfy and healthy!
Here's a 7-step guide to a happy HRV:
Step 1: Unplug and turn off your HRV.
Step 2: Clean or replace air filters. Every two months, remove the filters and give them a good vacuuming or washing with mild soap and water.
Step 3: Check outdoor intake and exhaust hoods. Make sure there's no debris or clogs blocking the airflow. Clear away snow or frost buildup in winter.
Step 4: Inspect the condensate drain. Slowly pour two litres of warm, clean water into each drain pan to make sure it's flowing freely. Clean any backups.
Step 5: Clean the heat exchange core. Vacuum and wash with soap and water to reduce dust buildup.
Step 6: Clean the grilles and inspect the ductwork. Remove and inspect grilles, then vacuum the inside of the ducts. If a more thorough cleaning is required, call a service technician.
Step 7: Service the fans. Gently brush off the dirt on the blades, and for older models, add a few drops of motor lubricating oil.
There you have it - 7 easy steps to a happy HRV!
