Today I performed a routine maintenance on your HVAC equipment. I checked all electrical connections on both indoor and outdoor equipment. Washed your filters flushed your drain lines checked your capacitor ratings and then check system operations after the maintenance. During the maintenance I noticed the upstairs zone was stuck open, which it explained why it’s so cold up there. I will go back in the history and see when we last replaced them and get an estimate emailed over ASAP if they’re no longer under warranty to replaced the zone damper actuator. Other than that, everything else is operating properly at this time .
