Anyone here using harmonic filters in HVAC or commercial setups?

[Davidjohn321]

I have been reading about harmonic filters and how they help improve power quality in HVAC systems, especially when there are multiple variable frequency drives running. Since AirCompare focuses on real world experiences with heating and cooling equipment, I wanted to ask if anyone here has tried adding harmonic filters to reduce noise, overheating or unexpected equipment trips.

I am considering them for a small commercial setup where the motors and drives cause noticeable distortion on the line. If you have used harmonic filters before, did you notice a real improvement in system stability or energy efficiency? Any simple advice or beginner friendly tips would be appreciated.
