[RFI] Single stage HVAC with ECM

[Kenny Silverman]

After talking to 3 hvac guys this week they all said they didn’t know of any AC motors on the market.  Only option has been single stage ECM, or go with a variable speed and hope there’s an RFI kit.  I’m going single stage. 

 Still waiting for the quote from one guy but I talked to him today and he floored me:  he spent the last 2 days signing up to ham radio and hvac groups to learn about RFI and WhAts the least susceptible to causing RFI.  You don’t get That very often!  He’ll be getting my business assuming he’s in the ball park of others.
