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.
I think the main problem with oversizing your AC/heat pump is if it’s bigger than the house requires, it cools your home too quickly and cycles on and off too much instead of running for a longer duration. It’s the cycling on and off that wears it out faster. I believe the rule of thumb is one ton per 1000 square feet. |
the bosch heat pump can be set to become a 2 ton unit from a 3 ton and from a five to 4 ton via dip switch but I think there's some automatic features that automatically adjust capacity between the Compressor and the air handler. And the air handler comes with two speeds so it's not fixed so that's a good thing. It seems it's a lot of simple things going on with a lot of fancy words they sprinkle on. Like super cooling and suction and saturation points - my favorite is liquid slogging. When I initially sought out a replacement thought I could just get a one stage and call it a day but then temptation grows and you learn about this new stuff on the market and it sounds compelling. Further if I enable the heating side of the heat pump it can be supportive to my existing heating system which might be ideal on those not so cold days but I don't get ventilation into my basement but still it's kind of a neat feature. |
I have the Mitsubishi HyperHeat HVAC and it is very quiet. https://www.mitsubishicomfort.com/products/heat-pumps Paul McGowan of PS Audio complains about how loud his HVAC is.... https://www.psaudio.com/blogs/ask-paul/what-are-the-best-air-conditioners-for-music-rooms Ron |
Do yourself a favor and look into a Mitusubishi mini split system, I have one in my garage, when it is running you can not hear any noise coming from the inside unit or the outside unit. When I am outside with the system running there is virtually no noise coming from the unit when I am standing right next to it. |
