What does this alert or notification mean?

Here are the different types of alerts and what they mean:

  • Service Urgent - An alert that notifies you that your HVAC system is in a no heat, no cool or no ventilation status. As a result, your system is not heating or cooling your home. These alerts require service by a licensed HVAC Contractor within 24 hours to fix the issue.

  • Maintenance - A notification your HVAC Contractor sets in your thermostat for planned maintenance or service intervals. These notifications can be for replacing a filter or UV bulb, for a 'tune-up' or for cleaning a piece of your HVAC system.
