On arrival homeowner wanted a heat tune up on both of the a/c systems. I inspected both the upstairs and downstairs furnaces as well as tested operations on both. The blower amperage was on spec, the inducer motor was on spec, transformer was on spec. I cleaned and tightened all connections on the boards as well as the high voltage. After preforming a heating tune up I found no faults on either of the systems. The furnace on both the upstairs and the downstairs are working properly at this time.
