Ack! Knowledge gap alert!
So this summer we blew some big bucks on new air conditioning. In the main house we replaced the aging and near death 18 year old compressor with a top of the line, 21 SEER rated Carrier. And in the apartment above the garage we put in a modern LG mini-split system. The air is great. The EMI is not
I've been living with it all summer. I can tell by looking at the waterfall display on the Flex when each unit is on and which unit it is
. However now that Fall is here I am quickly getting spoiled by the blessed lack of HVAC EMI. I want to take steps this Winter to see if I can mitigate some of this noise before next Spring.
First, please allow me to rule out the obvious answer: the compressors are on the back of the house. The OCFD is also stretched along the back of the house. They are not moving and are not going to get farther apart!
I am pretty much stuck with this arrangement. Next, let's rule out the "get new start cap's" approach. They are all brand new!
So, with those constraints, understand that I am handy with big electrons as well as small ones
If there is some modification or addition I can make to these units to make them electrically quieter, short of turning them off, of course
, please post it here.
Thanks!
P.S. a photo of the damn things...
