I arrived and found unit taken apart. I pieced the unit back and diagnosed a bad control board and a sticking gas valve. Estimates will be included for repairs. Due to units age and current conditions I highly recommend a unit replacement. New units will come with extendable warranties of up to 10 years for parts and labor. Repairs come with a one year warranty only. Customer was not on site and tenant would not acknowledge me being there. I spoke with customer over the phone and will be sending estimates and invoice over via email.
