My cousin is an HVAC guy and with 3 little kids he's hard to pin down but he'll be here for a party on Saturday...I'll definitely discuss this idea with him.

Be sure to do something nice for him. Giving professional advice on your free time can sometimes be a drag -- even when it's with family.

Fencepost,

You mean "especially when it's with family".

I'm sorry to report that nothing has worked. We had another little break from the sound for a while but then it returned one morning when my husband and I were both home and able to try a few things. To start, we flipped the a/c breaker, with no result. Then we turned off the water and opened a faucet in a second story bath. The noise stopped and I thought that might have done something because while it had made the noise five or six times that morning already, it didn't do it again for the rest of the day.

Unfortunately, the noise returned the next morning. My husband tried the water again, with no effect. And, coincidentally, the power in our neighborhood went out at the same time, and the noise continued through the outage.

And is continuing to this day.

We are really stumped and don't know who to call in for help. Unfortunately, it's not a noise that we can start on demand, so all we have to offer to the pros are a couple of videos and our descriptions of the events. We just moved in last May and I love so much about this house but the sound makes me not love it as much in the summer.

Also, I let my cousin off the hook. His wife was working, so he was solo-parenting with their three kids at the party. :D

I was able to view your video and the noise seemed to get louder when the camera was near the condensate line, could have just been strange harmonics between the noise, environment, and camera, but it did get me to thinking that you might be able to narrow down the location with a simple screwdriver.

Get the longest screwdriver you can find and use it as a stethoscope, place the tip against different things and put the handle tightly to your ear. Obviously, the noise will need to be present while doing this. You should be able to track the noise.

My ears are pitch sensitive, so sensitive, in fact, that I often hear light dimmer switches as their load increases (lights dim ). Your noise sounds much like an electronic whine to me. Look for one of those electronic rodent repeller gizmos left by the previous occupants, they work on high frequency sound, supposedly out of human hearing range, though not mine, I also suspect that if humans can hear them, they are ineffective/broken.

And if the only place that the noise is heard is in and around the HVAC unit, have your brother over to check it out. Since the noise happens sporadically, he may have to stay a while to experience it, hence your brother and not an AC tech sitting on the clock waiting for it. To help, you can be as prepared as possible with as much info as you can gather, such as specific times of day it happens, whether the A/C or heat has been running and how long, How long does the noise usually persist, anything and everything you can come up with that may help locate and/or duplicate the noise on demand.

Sprucee,

If in fact it's an electrical issue, why did it continue with the neighborhood in an outage or with the a/c breaker off?

The poster reports that: "Then we turned off the water and opened a faucet in a second story bath. The noise stopped and I thought that might have done something because while it had made the noise five or six times that morning already, it didn't do it again for the rest of the day ".....But then: "Unfortunately, the noise returned the next morning. My husband tried the water again, with no effect. And, coincidentally, the power in our neighborhood went out at the same time, and the noise continued through the outage."

Maybe it is connected to water.

Two words for you . . . Battery Power!

The thing is, none of us know, we're just tossing out ideas, hoping something works. :cool:

Well, if it is a pressure-related issue, it certainly could occur as a result of power loss, either from a power outage, or killing the breaker, or shutting off the A/C. When power is removed from something, the pressure gradually drops. At some range of pressure differential, it makes noise.

My money is that he coated it in spam until he couldn't hear it anymore. He had leftover spam, so he thought he'd come visit TOH for a while. As of this post he had 4 total posts, all of which were as informative as this one. :rolleyes:
