Customer called for a one time heat and AC maintenance. Heat Strips and Heat pump are working properly. Reversing valve is good. Heating over 100 degrees. AC is cooling properly as well. Cleaned dirt out of bottom of unit. Unit is 12 years old. I emailed customer estimates for blow in insulation, and a duct seal. Registers are blowing dust from boots not being sealed to Sheetrock.
