DO not buy this product. Long history of problems with TKV valve going out. Warranty only covers parts after 1 year. Home owner has to pay for the labor...more expensive than parts!!!

Works, but missing the point
October 24, 2025
I ran into issues with the HVAC system and not the furnace, but you can't tell because it has a comeback that is hard to read and you have to take it apart to get to it. We have cellphones with Bluetooth these days. Just put a qr for easy connect and show the real diagnostic. Additionally, the system started making noise, so we are trying a lower fan speed.
