For you HVAC people out there, could the problem be caused by a bad filter/dryer? If so, would replacing it stop the compressor from bleeding over and give it more life? Would you recommend the Amana or Lennox replacement. I see Lennox is up to SEER 21, but Amana tops out at SEER 16. What are the pros and cons?
Is there a way to just replace the single speed fan in an existing furnace with a variable speed one from the AC manufacturer? I really don't want or need a condensing furnace here in the desert.
Are the electrostatic air filters worthwhile? My ceiling filters for this unit are 22' up on the ceiling, which makes me long for one on the furnace to eliminate ladder work changing them out.
