New split AC System impact on sound.

I need to purchase a New split ac System (ie air handler in attic, Compressor outside). As with anything in this world so many complexities and my focus is to make things quiet when I’m listening to things.

Unfortunately, the compressor will be located outside of the room of my equipment. And I could choose a one stage or a variable stage heat pump that might be quieter. Anyone have recent experience and thoughts on how best to proceed for a moderately humid Area in the north east.

The problem with newer systems that I see is that the cooling coils don’t get as cold as they used to. Older R22 freon Systems which I currently have were more favorable toward reducing humidity in the home and the newer more environmentally friendly Freon varieties such as 410 and the newest 454b keep the coolant coil a little warmer which isn’t the greatest.

One benefit of variable speed systems is to address the very issue that you are concerned about, humidity. Those systems will run longer but, at a reduced (varying) capacity to have more time to wring moisture out of the air. I suggest that you put your contracter on the grill to get them to fully explain all of the pros and cons of these systems to help you make the best choice for you.

Yes indeed, oversizing an a/c system will result in reduced comfort meaning you will have cold but, damp air.

After 40 plus years in the a/c business I at least learned that the above is true.
