How quiet is a VRF Compressor? Mitsubishi install tested.

  I’ve had complaints over the years about AC Compressors outside of bedrooms making too much noise.  I even had a client a few years back get excited about GeoThermal because of the lack of an outdoor unit to make noise.  In general, I find it tough to have a conversation around a running AC compressor.  (typical conventional equipment is around 60-70db)

Mitsubishi claims to make outdoor units that are quieter than your average conventional unit.  They say they are quieter than conversation levels.

  I recently installed a Mitsubishi VRF (Variable Refrigerant Flow) unit on a jobsite and I took my Extech Sound Meter with me to test and see for myself if these units are really as quite as they claim.

    Can I put a mini split compressor indoor in a vented closet with soundproofing? If yes do I need a suction fan?

    • I’m not certain, but in general it sounds like a bad idea. I would expect the efficiency to plummet. You’ll need to talk to the manufacturer directly, but I’m guessing that they will say No. Best, Matt
