The noise

My air conditioner has been making a whistling sound lately.

  • The sound is hard to detect.

If I’m watching cable or doing other things, I can’t hear it, but when I’m sleeping, it’s very distracting. The whistling only sounds when the air conditioning is on. It’s not always on, which makes this even more annoying, because If it whistled constantly, I could tune it out. The rest of my family says that they can’t even hear the noise. That others can’t hear it makes me think I am going crazy! But I haven’t had good sleep in over a month, so I called our air conditioning technician. The HVAC technician came and readjusted the little door that closes in the air filter. As soon as he did, the whistling ceased! Apparently, my husband didn’t close the door correctly when he changed the filter last week! Air rushing through the little gap in the door is what was causing the whistling! I am happy it was easy to fix. Too bad I hadn’t thought of this myself; it would have saved me money! I’m glad I’m not crazy, though, hearing something no one else could. I hope I get better sleep tonight. I bet I will, since the sound is gone.
