For the good news get ready for the sticker shock of new units. In the ever lasting search for higher efficiency and free energy heat exchangers have gotten paper thin, coils are aluminum and thin, the new ozone saving refrigerants run at ungodly headpressures, motors are computer controlled multi speed units fit for space travel. With $1000 motors, blown coils and lines, burned out exchangers, and fried circuit boards you can expect 10-12 years service from a unit that costs double to buy and a fortune to maintain. But hey you save $150 a year in energy. I want my old units back with cast exchangers and solid state controls. 30 years of service with cheap repairs, I'll gladly pay for the wasted energy. I don't need a 14 speed condensor motor anyway. Sure am glad the tree huggers can enjoy their $10 lattes while basking in the glow of saving the world with energy savings. Now go see how much energy is used to make new units to replace these pieces of *+=\\.|{}#. :soapbox::bang head:
