Less than 30 days run time, thermostat has reminder
I change after 30 days run time. As a side note, the HVAC technician stated he has never seen someone so religious on it. He says you always know who changes them religiously or not by how white they are or not when they get there. Meaning really white, they probably change ever 6 months right before their checkup :-)
