What are the main steps in a gas furnace maintenance? I'm going to call a tech out to do a maintenance before we get into winter, but I want to make sure he covers everything... (last hvac tech who came out on a no-cool at my house only checked charge level, when the real problem was a dirty evap)
A forced air furnace clean and check:
Remove and clean burners and pilot
Condition of flames
Visual check heat exchanger
Electronic CO test
Vacume and clean in and around furnace

Tnx. I'll make sure this all gets covered when the tech comes out.
