So every year I would have a technician come out and service our furnace. I'm not sure what all it entails to service our furnace, aside from changing the filter, but last year I learned quite a bit about our furnace when I replaced the circuit board, inducer blower, and then the pressure switches. (full post here: Furnace keeps going into lockout)
Seems like after all that, servicing my furnace myself shouldn't be too bad. I took a look at some lists posted on different sites that detail everything that's done, such as this one: https://columbiahvac.net/tune-up
- Blower – inspect assembly (?)
- Clean or change filter (?)
- Verify limit operations (?)
- Measure and record delta T (?)
- Clean flame sensor
- Clean and cycle condensate pump (90% or better EF) (?)
- Measure and record amp draw to blower (?)
- Measure and record amp draw inducer (?)
- Inspect flue pipe
- Measure and verify ignition protocols (?)
- Clean burners (?)
- Tighten electrical connections
- Clean and adjust pilot assembly (?)
- Clean exterior
- Measure and adjust gas pressure (?)
- Brush and inspect heat exchanger (?)
- Conduct bubble test for gas leaks
- Vacuum burner compartment
Most of these things I've done, the ones with a (?) are the tasks I'm unfamiliar with. Some of the things I wonder about doing myself, like measuring output and all that, but it seems like a lot of it would be pretty simple.
Can anyone give guidance here? Or recommend any good online resources in particular that would be good to follow when self servicing a furnace?
Thanks!
