Admitting he’s no better than the rest of us at staying on schedule, Eric walks through a real-world inspection of a neglected unit, starting with safe shutdown and filter replacement. He explains how an ERV works, what the core does, and why proper filtration and airflow are critical. From vacuuming the heat-exchange core to cleaning intake and exhaust hoods outside, Eric shows how simple tools and regular attention can restore efficiency and reduce noise. Along the way, he shares recommended maintenance intervals and tips for staying on track, proving that a little routine care goes a long way in keeping your home’s ventilation system running as designed.
