So another update. The contractors (more knowledgeable son) came and did about 3 hours worth of work.
He installed a new pipe that I believe connects the duct work underneath back to the return air pipe. There is also a weight balance on this pipe. I believe it has something to do with the zones and the emergency valve, the air will return back into the air return supply (you experts can correct me if im wrong, which probably I am).
He also changed the position of the air temperature sensor to a different location.
Also worth noting there amber light error code is now gone and replaced with a constant amber light. Is this a sign that the machine is functioning properly or should the amber light be completely off?
However, one thing I noticed is that lets say room temp is 70 and I set thermostat to 75, it takes an hour or so for the temperature to rise to 75. It seems too long for me. I remember him saying something like he adjusted the high heat level so that the machine wont go into high heat as much which might be why it is taking so long for it to rise 5 degrees.
Any thoughts from the experts?
I have attached a couple pics so you can see the new duct, weight balance, air temp sensor placement.
