Arrvied onsite per customer complaint of no heat inside the home. Upon arrival I found the furnace to a 14 year old Dayton Furnace. Provided Aaron with a few different options. Aaron elected to go with a Furnace Diagnostic. Found the unit to have the gas shut off and the power to be off. Turned gas and power on. Gave unit a call for heat at the thermostat. Unit kicked right on, inducer was pulling 1.14A rated for 1.7A. Blower was pulling 6.88A. Inlet gas pressure was right 8.8WC. Flame sensor was pulling 1.7-2.2UA. Provided customer pricing to replace flame sensor. Measured for my Delta T and got an air temperature differential of 40 degrees. Found 4 registers blocked/ closed inside the home. Found 2 filters on the return air side as well. Opened all available registers and informed customer. Tested for Carbon Monoxide inside the home and found none. Provided customer with a few different options to upgrade their heating system. Customer declined to move forward with any more work. Cy
