Which manifold did you put on your DC?

I have seen goodman, rheem, carrier and several others run the ibm with an open limit. I think most furnaces do that now. The funny thing is getting the call and the homeowners says "my blower has...

funny, Sonoma is the county i took the job in and learned about this code during installation.

Which tstats do you use with simular features/touchscreen that you can adjust the temp differential for aux on?

X2. The biggest five companies here use this technique and i know this because i was one of them 6 years ago. I was specifically hired because of my sales skills more than tech skills. Thats why they...
