I installed Supco SPP6e hard start capacitors on our two 19 year old Duo-Therm 13.5 Btu/h A/C's. Running our Onan 7KW generator, there's noticeably less of a "grunt" when the A/C's start up now. The start cap that I removed from the rear A/C was cracked and showing signs of corrosion. I suspect that's likely what caused the control board to fail. I replaced that today as well, so we should be set for the summer heat now.
