Upon arrival, customer explained to me that 3 of the systems were not operating properly, main floor and both basement systems. Main floor system has a natural gas furnace, draft inducer assembly had trash in it not allowing the inducer motor to start which was causing the furnace to lockout. Removed trash from inducer assembly and furnace is working properly. 2 basement systems are both heat pump units that are never on and running unless company or son is home. Both basement units are working properly. Advised customer to keep basement system on at a lower temperature just so it doesn’t take as long to bring the temperatures up from the systems not running at all.
