I feel that my window air conditioners are too noisy. Actually, there is nothing wrong with the air conditioners; I am just too sensitive to noise especially when I need to go to sleep. I am thinking of replacing them with some kind of split system that has the noisy compressor placed outdoor. Because of the fact that my house is not suitable for running ductwork (no attic), I probably prefer a ductless split system that has a blower indoor. Now the question is:
How quiet those ductless split system is as comparing to a window air conditioner?
I would really hate to spend a lot of money getting a ductless split system installed and then discover that the it (the blower) is not much quieter than the window air conditioner that it has replaced.
My questions are:
- The spec of one of the most quiet mini-split system says that its indoor unit generates 40-db or something. According to
- How a noise level was rated? Are they all rated 3-ft away from the air conditioner?
- What's the common noise level of a modern window air conditioner being sold within the last 2 years or so? Something like low-50-db or high-60-db? I don't have a sound-meter available (at least not yet); I cannot measure the noise level of my existing window air conditioners.
Thanks in advance for any info.
