Technician arrived to perform a two system promo tuneup on two Concord furnaces. Technician adjusted gas pressure, checked amps, checked static pressure, checked temperature differential, cleaned flame sensor, checked filters and insured proper operation. Technician made estimates including the friends and family club, surge protection and duct cleaning but the customer did not want to move forward with any of the options and stick with the $39 each tuneup. Both systems are heating properly
