It doesn't look like my link came across properly. The link to the soft start
units I have is: http://hypereng.com/ ;
or simply hypereng.com.

Just learned of something new to me - soft start for air conditioners. As I
will be replacing both air handlers and compressors this year and I have a
whole house backup NG generator, you have tweaked my interest. Where do I find
more info on them?
On a side note I heard mention that variable speed air handler blowers can
cause hash compared to quiet fixed speed blowers. Any truth to that.
Tnx for any feedback
N2TK, Tony

Hi Tim,
I’m a bit surprised they aren’t offered as a standard add-on. I was pretty
skeptical until I installed them and when I saw the difference they made. I was
pretty much blown away!
I’d never considered the issue for cell sites but now that you mention it, of
course!
