**This tune up turned into an evaluation, When I arrived system was not running. Turns out thermostat was not placed correctly*** Upon inspecting the inside systems, I noticed that one of them didn't have a filter at all, Not the return grill nor the machine itself. The other system did have a filter but it was dirty, clogged up I don't Believe that the filters have ever been replaced, And if they have it was a very long time ago. seeing the inside of the Return Plenum, I noticed that there was a lot of dust and Debris Accumulated. ***Highly recommend a duct clean and a furnace super clean*** April air filters upgrade recommended as well Don't need to be replaced until six months up to a year Condensers do not have a soft start or hard start system Installed. Highly recommended to get one. Disconnect box is burning up, getting charred On every start up. I recommend replacing safety disconnect box **We need to schedule an electrician and a plumber to come out** Electric
