Hi guys. First post and hope you have some feedback.
Customer wants to investigate the possibility of saving energy with his existing furnace (circa 1992). He is looking to upgrade his Thermo Pride OH16-125 furnace blower motor (PSC-Type) with a Genteq Evergreen AF or IM ECM motor. I have read the standard sell sheets that claim this motor will operate at 73% less wattage than the standard PSC motor. Right now, the system operates in a single speed setting.
This furnace is used for HVAC, and we recently replaced the evaporator and condenser with a Carrier Infinity Puron system. The whole thing is controlled with a Carrier Comfort Zone II system (5 zones).
Question for the group is if anyone has ever 'upgraded' a furnace like this with just an ECM motor? If so, has it resulted in anywhere close to the energy savings purported by the ECM sell sheets? The rest of the Thermo Pride furnace is in great shape, and I would hate to shock him with a story that he would need to rip it out and replace to save him energy.
