I’m Nathan, and I’ve worked as an HVAC technician for over 10 years. This exact complaint comes up a lot on service calls: you look at your Ecobee and it clearly says No equipment running, but you can hear air moving and the blower fan won’t shut off. The good news is that this problem … Read more
I’m Nathan, and I’ve been an HVAC technician for over 10 years. One of the most common winter service calls I get starts like this: “My ecobee is set to heat, but the vents are blowing cold air.” Sometimes it’s a simple thermostat setting.
