I just got rid of the old fuel oil furnace for heatpump with electric backup. The noise and draft from the extra air movement was unexpected and now I'm wishing I would have kept the old system. Would I have been better off to go with propane or back to fuel oil? Is there something I can do to correct this? With my old system I couldn't even here it run. I have a 4 ton goodman system with vairiable speed motors.
