I had a remote thermostat installed a few years back. It has failed and another one has been installed. I seem to notice my heating system is much quieter. It had been bothering me, blowing very hard and noisy. Uncomfortable heating and cooling. It's a Goodman 92.
With the new thermostat, I notice that I don't even know the heat is on. The temperature is consistent.
Is it possible that the 2 stage wires weren't hooked up correctly that would cause it to run 2nd stage only?
