Six months ago - I installed two new Variable speed furnaces.
One seems to be working fine. The other is not cooling as well as the other, and the fan seems a lot quieter. My gut tells me that the blower is not coming up to full speed as it should. (we are missing the set point of 75 by five degrees)
How do I diagnose the full operation of the blower motor (and control board).
Thank you all in Advance for your help
Another 100 degree day in Utah!
