How to Fix a Noisy Air Conditioner

  • Transcript

    LESLIE: Now we’ve got Bob in Florida who’s dealing with a very noisy air conditioner. What’s going on?

    BOB: Oh, it’s when it’s – it’s a new air conditioner. When it comes on, it just sounds like the wind is blowing through the house, like a real hard wind.

    TOM: Yeah.

    LESLIE: Now, is the whole system new or just the condensing unit?

    BOB: Well, not the ducts up in the attic. They’re not new.

    TOM: So you were used to a quieter system than before this was replaced. Is that correct?

    BOB: Oh, yeah, way quieter. Uh-huh.

    TOM: You might want to check and find out if the fan speed is adjustable.

    BOB: OK.

    TOM: Because it sounds to me like they’re pushing so much air through there. That’s what’s giving you that whistling noise. This is all workmanship, OK? This is a – you need to call that contractor back and explain that you’ve been living with this system for a long time and it never sounded like this until they replaced all the equipment. And they may have not have it set up correctly. If the fan is going too strongly, if it’s too high of a speed, it could be pressurizing those ducts. It can’t get enough air out and as a result, you’re getting all of that noise and all that whistling sound. This should not be a difficult thing to resolve.

    BOB: Alright. I appreciate it very much.

    TOM: You’re welcome, Bob. Thanks so much for calling us at 888-MONEY-PIT.
