Upon arrival customer showed me location of thermostat and attic system. Changed out the filter of the system and replaced with customer provided filter. Spoke to the customer who only issue was the noise of the system. Initially found on the indoor unit that the breaker was off at the box. Found surge protector operating properly at this time. Blower motor clean free of debris and amping correctly along with heat strips. The coil was clean free of debris and drain line was clear at this time. Going to the outdoor unit found the coil clean free of debris. When listening to the system explained the sound was normal. Pressures were in the correct range. Electrical connections clean tight and secured amping within manufacturer specifications. Customer approved for membership and compressor blanket. Need to order part.
