It was time for a major spring cleaning of the HRV (heat recovery ventilation) whole house continuous fresh air ventilation system. All filters were replaced and the heat exchanger core got a bath. Now the system is ready to tackle all the pollens in the air to help the ones with allergies breathe easy.
