Technician arrived to perform a yearly friends and family club furnace maintenance on two furnaces. Technician adjusted gas pressure, checked amps, checked temperature differential, checked static pressure, cleaned flame sensor, changed filters and insured proper operation. Technician noticed the panels on both humidifiers needed changed and made estimates on getting that done as well as duct cleaning. Customer wanted to move forward with the humidifier panels and scheduled a day to have them changed. Both systems are heating properly at this time.
