What are normal AC noises?
A low, steady blowing noise is normal for an air conditioner, as it continually blows cool air through the ducts and vents of your home. If the noise more closely resembles buzzing or humming than a gentle blow, loose parts or electrical problems may be to blame.
What kind of noise does an AC compressor make?
High-Pitched Whistling or Screaming This is a warning sound. If it (or a similar sound) is coming from your AC compressor, you need to act quickly and turn electrical power to the unit OFF. It might switch off on its own—which is good.
Is the AC blower running in AC mode?
When running in AC Mode, the outdoor fan and compressor kick off just fine. The blower fan seems to kick off as well, though it’s not putting out very much air. I can feel cool air blowing out of the vent but it’s a small trickle, and it’s not enough to keep the house very cool.
What’s the best speed for an AC blower?
Because this process is complicated, working with an expert in AC repair and maintenance is a worthwhile venture. What is the Recommended Speed for Your Blower?
What happens if air handler blower speed is too low?
This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.” This could result in liquid refrigerant floodback that would likely cause compressor failure.

Why does my AC make a loud noise when I start it up?
Outdoor fan motors and indoor blower motors squeal loudly when they’re going bad. The blower wheel and housing will also squeal when they malfunction. For some units, this sound is normal upon start-up. You should be able to identify whether it’s a sound that the unit always makes or if it’s something new.
