Maintenance performed on Goodman system. Checked amp’s of blower motor and furnace itself, system using low amps. The filter was dirty and replaced. The temperature split was in range to heat home properly. Coil is clean, and gas line is in open position. Turned heating off and checked through all electrical components. All components operating correctly. System is operational upon departure. Motor control was replaced due to motor working harder with dirty filter. Also filter replaced.
