Upon arrival I began the furnace tune up. This is a Goodman systems that Ideal Temp installed back in March of 2022. I changed out the filter which is a 20x25x4 inch media filter. The old filter was extremely dirty. This is a reminder to change out your filter every 6 months with that type of filter. I also tried cleaning the return vent the best I could today. The blower wheel is very dirty and should be cleaned in the near future. The running amps on the inducer and blower motor were within manufacturer specifications. I took a temperature split on the system. It is rated for 15 to 45 degrees, 97 degrees(supply temp) - 67 degrees(return temp) = 30 degree temp rise is within specs. I did a test for any CO leaking from the heat exchanger but didn’t get any hits which is great! If you have any questions or concerns please feel free to call us!
