How can I determine why my furnace is not blowing enough heat?
After posting this I noticed that the furnace control board has an LED that was flashing. Checked the manual and it was an error code saying the pressure switch contact did not close after the inducer was energized. This means nothing too me but before I was going to call a pro I wanted to take a look inside. Pulled out the blower motor and everything looked spotless. Heat exchanger pipes are very clean and there is plenty of room for air flow, no need to worry about internal blockages.

After putting it all back together the error code went away and the LED is green (everything working). Maybe cutting the power caused the electronics to reset and everything is fine now. Seems to be working but who knows. If the issue comes back I will be having a pro come take a look at it.
