Me: OK...what seems to be the issue?
Homeowner: Well, it's running in emergency heat. umm....can not changing your filters cause that?
Me: How long has it been since you changed your filters?
Homeowner: maybe 6 months?

:club: Go change your filters, turn your breakers off for 30 second and then back on. Restart your system, wait 30 minutes and then call me back.
*30 minutes later*
Homeowner: Oh wow...my heat is working now!
Me: O rly?
Homeowner: Yes!
Me: Ma'am - change your filters once a month or you will kill your equipment.
