Customer Question

hello my furnace stop heating, the AC is fine the tech said a damper was missing
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: ive lived here for 2 winters with the heat working just fine
JA: Do you plan on doing the work yourself?
Customer: he said the damper was missing and that's why it wont heat....ive never had it serviced so I don't know why it would be missing, again it worked for 2014/2015 season ....I did have the thermostat replaced--not sure if that is a problem
JA: Anything else we should know to help you best?
Customer: no, im just questioning the damper being the problem since, it has worked for two years without one
