Hi need some advice my 4 ton heat pump was installed nov 2003 when I built the house.It has been tripping the breakers and today a repair person told my wife that the compressor is pulling too many amps and it be cheaper to replace the heat pump alone with the inside air handler because a compressor would not last that long. is this true? also what would the average life of a heat pump be? and what brands are among the best and do any last more then 10 years? I been reading in this forum and it seems the higher SEER the better would it be worth the extra? sorry I am asking so many question but figure this be the best place.I am in the Cincinnati area ..all advice is welcome and thanks for your time George
