HRVs need to be balanced so that air intake matches exhaust output. The most common HRV maintenance is to change the filters on a regular basis. Typical maintenance for an HRV system involves turning off and unplugging the HRV for safety reasons. Air filters should be cleaned or replaced. HRV filters should be cleaned at least once every 2-3 months. Most HRV filters can be cleaned with mild soap or water or a vacuum. Older units come with replaceable filters.
Outdoor intakes and exhaust hoods need to be checked for leaves and other obstructions at least once per season. Snow or frost can buildup during winter months and block outside vents. If the HRV system has a condensate drain (a pipe or tube visibly coming out of the bottom of the unit) it should be cleaned to ensure that it is flowing properly.
The heat exchange core should be inspected to maintain efficient operation of the unit. This type of maintenance should be performed at least once a year.
Ductwork leading to and from the HRV should be properly inspected and cleaned once a year. This includes removing and inspecting grilles that cover the duct ends. Dirt accumulates on the fans. These should be inspected 2-3 times a year.
New models are designed to run continuously, while older models need motor lubricating oil to run efficiently. Due to the requirements of extensive maintenance, a professional should perform inspections and regular cleanings.
