Upon my arrival I spoke with the customer about the concerns he had with the blower not coming on with the furnace. I performed a diagnostics by pulling static pressure across the return and the heat exchanger then the return and the coil. I found that with the speed setting the air movement system is set to the unit is getting the proper amount of air flow. I also checked the pressures, temperature rise, safeties and the amps. Found that everything is operating within manufacturer specifications at this time. Customers concern was that they didn’t really feel air flow coming from the vents but the system was maintaining the 71° set point that desire. I explained to the customer about the how the system calls for a higher demand of airflow in the cooling vs the heating. I also went over how we upgraded the size of his return plenum and that his old system had a PSC motor and the new one has an ECM motor so they are going to operate and perform differently. I then spoke with the custome
