Re: Variable speed drive

Thanks for the ideas so far. Replacement blower motor looks interesting... wonder if it's just a regular induction motor with a built-in drive?

Laserfan, the blower doesn't contribute too much to the inrush current of the whole system, but it's something. I added a hard start kit to the compressor and that made things much easier on the generator. Last summer when the power was out for 7 days, I ran the air handler blower constantly to avoid the synchronized start with the compressor.

I added hard start kits to my compressors and two out of three blew-up! I took the third out before IT blew up too! Dunno why/how this happened as they were properly sized & wired, or so we thought (me & the HVAC tech).

Anyway those RESCUE motors look interesting to me as apart from the energy usage and "lights dimming" issues, I also find our blowers to be inordinately loud (not the motors per se, but the airflow) and maybe those would help with that too. As it is, on one of my blower motors I re-wired to the lower RPM windings...
