What maintenance consideration is important for HRVs and ERVs?

Regular cleaning is essential for Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) to ensure they function efficiently. Dust, dirt, and other contaminants can accumulate on filters and within the unit, which can hinder the airflow and reduce the ability to exchange heat or energy effectively. Regular maintenance, including filter cleaning or replacement and ensuring that other components are free of obstructions, helps maintain optimal performance, extends the lifespan of the unit, and contributes to the overall indoor air quality.

While it's true that professional installation is important for the correct setup of HRVs and ERVs, proper ongoing maintenance is crucial for their performance, making regular cleaning a key consideration. Additionally, maintenance should not be limited to winter; it is a year-round requirement to ensure that the systems work efficiently regardless of the season.
