Labels upside down. This heater model was installed based on existing home air input and output configuration. Therefore, labels should have been attached to the heater after installation. Dealer provided a new set of labels. Problem, I don't know best method to remove old labels.

Upgraded replacement for a 20-year old unit
November 15, 2025
This unit replaced another Carrier furnace we'd had trouble-free for over 20 years. Our service company, Hi-Tech, had installed the original system and our technician, Josh, recommended this unit as an upgraded replacement. Installation was great and it has performed well ever since.
