No heat call. Customer signed up to be our customer/member. Signed up for two maintenance programs. There are 3 furnaces in this house, only signed up for two at this time. No heat was due to cracked hsi on carrier furnace. Tested flame sensors, pressure switches, hsi, fan motor amperage and capacitor, inducer motor amperage and gas valve voltages. Replaced hsi and flame sensor on carrier furnace, and replaced fan motor capacitor of American standard furnace. Customer is using one visit from both plans at this time and will have two visits for each condenser in a couple months for cooling season. Gave customer estimate for battery back up sump. Customer wants Chris to call him about generator issues. Maintenance plan is for basement furnaces.
