HVAC Service Complaint no heat Downstairs unit had shut off breakers, blown low voltage fuse from knicked pressure switch wire outside, and a bad dual capacitor on heat pump system. Upstairs unit had a blown transformer due to no fuse protection and a 24v short on the 2 wire going to straight ac outside.
