Noise level from mini-split in this cold snap

11 years ago

We have a new Mitsubishi mini-split which heats an also new studio apt. we just added in our old garage. I wasn't home last night when the temps went under 15 degrees, but my husband turned the heat off in the studio about 3 a.m. because the minisplit was making so much noise. He said it sounded like it was "in distress." It's also right outside our bedroom, so it probably bothered him.

This is completely new to us, so we don't know what to expect from it. I asked him to get in touch with the general contractor today, and if he has time he will But I would be grateful for any knowledge from this group. Thanks.

I would not be surprised by high fan noise. The lower temperature might be making the fan run faster. What model is this, a hyper heat (h2i)?

The outside unit gets louder as it's colder and when its Below 15 i can hear the outside unit speeding up; as the temperature drops. I did have one issue sounding like it was dying but turned the site handler fan speed down and it went waited so i turned it back up. Idk if the unit was slowing down or what but it was fine after the sun was up a while. Did it sound like the air handler or outside unit?

It is a macine.it will make noise at times. Poor choice on the placement. I think I'd record it and play it back to your installer or factory tech service and see what they think. If it ok your choices are, move it, live with it or turn it off. We turn ours off at night and find that it only takes 10 or so minutes to bring it back up
