Although my understanding is that the Texas SOP relieves me of the responsibility to inspect zone controllers, inconsistencies in heating & cooling is by far one of the biggest complaints I hear at the beginning of warranty inspections when I ask “do you have any questions or concerns that you’ve noticed over the past 11 months?”.
So I would like to know more about inspecting zoning controllers. Do you have a specific routine for verifying proper operation?
It takes extra time but necessary in my opinion. As you stated, heating/cooling complaints are at the top of the list. I recently performed a new home inspection in which the downstairs t-stat and the upstairs t-stats were inverted. Down controlled up and up controlled down. I don’t care what the SoP says, the customer would have been upset.
Yep, I just did a warranty inspection with the same situation that I didn’t pick up on during the initial. They had it corrected before I returned for the warranty, but I want to catch that in the future
