Which HVAC capacitors are most likely to fail? (run caps, startingcaps or does it matter)If there a brand that's better then the rest?. It appears they allcome from Mexico or China. I can't seem to find Mallory or GE anymore.If a dual 440V cap is rated as 60+10 is either a 55+10 or 60+7.5 anacceptable substitute long term?TIA
