Ok, you asked for it
First, the repair guy went in the attic where the air handler is located. Due to reasons which will be made available soon, we can only run the heat on emergency heat. Regular heat just blows cold air. One half of the emergency heat was not working, some controller gone bad. He replaced the controller, parts and labor about $210. While he was here, he checked the outside unit, condenser. He found out that a switch? the changes the fan direction when switching from ac to heat was bad. This is why we have to run it in emergency heat. He said the switch wasn't worth fixing. The whole system may last a year or so. After the repairs were made and we were chit chatting, I learned some things about my system and also about hvac contractors in general, especially the not so honest ones. I can honestly say, Tennyson's HVAC from down south in the county is my new go to guy. He should be getting the job of installing a new system.
