The Tec was wonderful to work with. Supreme Air is a great company to work with.
While testing unit 1 after replacing heat exchanger I inspected unit 2 because customer mentioned that it was overshooting setpoint. I found system was satisfying thermostat properly. Checked heating operation. Measured heat rise and amp draw, checked gas pressure and cleaned flame sensor. Speculating space heater possibly adding heat and increasing indoor temps. Unit operating normal.
Upon arrival I went to roof and started removing panels. Removed inducer and manifold to get to heat exchanger. Removed heat exchanger and installed new one. Then installed bracket for blower assembly so it doesnâ€™t wobble. Ran fan only and verified quiet operation. Restarted unit and ran heat. Unit shutting off on high Limit, first stage heat. Found gas pressure at 2.3 inches, rated for 1.6 inches in first stage. Lowered to spec. Ran second stage and found normal gas flow rate. Checked heat rise and amp draw. Unit operating normal at this time.
Cap off hot and cold lines under kitchen sink and turn water back on to home valve under sink broke and flooded kitchen and basement dust wanted lines capped off due to cabinets being replaced removed water from water heater pan from the leak and restarted gas water heater. Restarted gas furnace also they were turned off to when basement flooded to prevent any more damage
Replace blower wheel, housing and frame. Upon arrival I went to system and removed paneling. Found I do not need to replace blower assembly. Blower was rocking back and forth due to cracking in the frame of unit, similar to unit 1. Went to supply store and picked up reinforced steel. Came back and cut to length and installed bracket underneath blower housing. Secured the bottom of panel and side of panel. Also secured and all sides of the cracks to keep blower from rocking. Put unit back together and tested blower. Blower not rocking or making loud noises. Ran heat and checked operation. Unit operating normal at this time. Office will be sending revised invoice. Waiting on parts for front lobby unit, system shut off.
