Need some help please. We have 3 buttons on our thermostats. They are: AUTO, COOL, HEAT.
Should the A/C fans blow 100% of the time when COOL or HEAT is being used.
I would prefer the A/C fans blow only when A/C is being used, but it they never shut off during both A/C and HEAT operation.
Is this normal? It's noisy and we don't like it.
