Technician thoroughly inspected the upstairs and downstairs systems. Both of the systems are operating properly. First stage heating, second stage heating and emergency heat\heat strips are all functioning normally. The resident was attempting to feel air coming out of a return vent that actually does not blow air, It sucks air in. Return vents pull air, in. The supply vents deliver air out of the ductwork into the rooms. Also, the resident was unaware that this equipment does not simply turn on and off. This equipment has staging. So first stage heat has a different blower speed than second stage heating. Technician spent significant time explaining how this new equipment operates with the staging to be more energy efficient. Resident is now more aware of what to expect from the systems as they operate.
