After discussing my RFI concerns and house needs, this one HVAC guy is recommending Carrier 14 seer single stage units but both single stage air handlers have ECMs. If the units are single stage, is

If there is a variable-speed-contolled motor, there will be noise. I don't know what ECM is the acronym for. :) 73, Jim K9YC _______________________________________________ RFI mailing list RFI@conte

Electronically Commutated Motor. And no, they aren't by design noisy. Poorly implemented ones can be though! I have several in my HVAC and they are quiet. The air handler blower motor and condenser c

They are also more expensive and unreliable than PSC motors and probably will never pay for themselves in energy savings.  But they are designed to federal energy standards where cost to the consumer

In 2012 I had a Trane heat pump system with an ECM in the air handler installed. It was quite noisy on HF. I was able to reduce the noise to negligible levels with #31 ferrites on the motor and therm

They are a much better matched to the airflow requirements of a well balanced HVAC system allowing for better humidity and consistent temperature control. It's not just about energy savings of the mo

I agree with Steve. I replaced my unit 3 years ago and after placing #31 cores on the motor wires no interference from the system at all. My home has seen an improvement in air quality and overall co

I have a single stage furnace that's about two years old. I did my homework and purchased an American Standard (Ingersoll Rand) running an AC blower motor. It's 80% efficient which is fine in my opin

After talking to 3 hvac guys this week they all said they didnt know of any AC motors on the market. Only option has been single stage ECM, or go with a variable speed and hope theres an RFI kit. Im

Wow! If this works out for you, be sure to post his info. Another thing for him to look at is my RFI chasing page. There's a short discussion of variable speed motor controllers on page 14. In the se

FWIW, I've had two Bryant furnaces over the past 28 years, with no RFI problems in either direction. Both had variable speed inducer motors and two speed blowers. The blowers may just be two speed in
