  1. Hot water recirculator noisy and full of red gunk

    Plumbing
    We had bathrooms remodeled in 2016. The contractor installed a hot water recirculator and pex tubing to create a return path. Within a year, the recirculator began making a rapid clicking noise, which became louder over time. The contractor said that was normal and they all do that (i.e., he...
  2. Reduce outside A/C compressor noise

    HVAC
    My neighbor complained that the A/C is too loud and they are unable to sleep in the night. Our compressor is about 12 ft from the fence and their bedroom window is about 10-15 ft from the fence.

  3. AC fan motor vibration and shutdown noise. Video included.

    HVAC
    Hello, This is my first post. I recently tried my hands at replacing the ac fan motor.(After AC person told me the fan wasn't rotating as freely as it should. And motor would probably have to be replaced soon.) I wish I took notes on how the unit sounded/vibrated before doing this. Long...
  4. Carrier gas furnace rattling sound when heat stops

    HVAC
    I have a Carrier MCB58 gas furnace and since about two weeks it started making a rattling sound when the heat stops (transition from heating to fan circulation only). The filter is new. The blower is clean. The sound seems to be coming from the inducer. Here's a video of the noise (noise...
  5. Reduce Noise Between Interior Bedroom Walls

    General DIY Discussions
    Reduce Noise Between Interior Bedroom Walls I thought this would be a simple project but reading a lot of conflicting information. We have a new build finished home, contractor grade. We can hear conversations between the bedroom walls like there is no privacy, even light snoring would wake...
  6. Static Pressure Regulator Loopback--Good idea?

    HVAC
    Just had a great HVAC tech come to my place to look at the ductwork because the AC is unbearably loud. Thanks to some great folks on here, I found out that when we upgraded from 3.5ton to 5ton Trane AC, we needed to adjust the ducts to allow for more incoming air and outgoing air. This new...
  7. Heater Makes Loud Whirring Noise Often

    HVAC
    Hi all, I own a small manufacturing business in Minneapolis, and we have been experiencing a loud noise on the colder days every 30 - 60 minutes coming from one of our heaters. It starts and lasts about 30 seconds, fading in and eventually fading out. It happens more often on very cold days and...
  8. GFI Buzz

    Electrical
    Just today, I noticed probably a half dozen GFIs around my house are buzzing. I am pretty sure it just started, since some are a bit loud. I know some of these are on different circuits, and not every GFI in the house is doing this. Some buzz, some don't. No recent electrical changes. I cut...
  9. Friggin geese

    Pest Control
    Let me preface this by saying that I DESPISE geese. They're annoying, they poop everywhere, and they walk slowly across roads. Anyways, my high school is having a serious problem with geese on its baseball fields. They're getting the field and stands very dirty, and we'd prefer to not have...
  10. Bathroom faucet stream too loud/fast

    Plumbing
    Hi there, I recently had a double sink installed and have noticed that the streams coming out of the faucets are very loud and fast. My expectation was that when the handle is only slightly pulled up, it would be a light/quiet stream that gets progressively faster as the handle is pulled...

  12. Front-load washer basket vibrating

    Appliances
    I've got a Frigidaire Gallery front-loading washer that I bought in 2005. It runs great, but today when it reached the final spin cycle, at the highest speed, the basket began to shake violently inside the tub (loaded and unloaded). It sounded and looked like it was banging around inside the...

    Building & Construction
    I am trying to diagnose a metallic creaking/popping noise behind drywall. I recorded 3 occurrences of the noise a the following link: youtu.be/9rIWIkw1Yzk The sound in the video is low so you may need to increase the volume because in reality the sound is as loud as a normal conversation...
  15. Blower motor noise: need longer return duct?

    HVAC
    I hear a lot of blower noise in my living room. When I moved in, I got an HVAC contractor to add AC to the existing forced air heat system, and he said the problem is that the return air duct is just too short. Houses around here (1950s neighborhood, San Francisco Bay area) didn't originally...
  16. Improperly ground Electrical Service Panel(s)?

    Electrical
    I get a buzzing from a lot of different appliances in my house. From lamps (using compact fluorescent bulbs), to guitar amplifiers. The house was built in 1907 and some of the wiring had been redone in (maybe) the 80s or 90s. The house is technically two flats, so there are two Service Panels in...

  18. HVAC ductwork from an air conditioner hole in the wall

    HVAC
    So I'm in a building from about the 70's that doesn't have central air. I wanted to close up all the windows and use a fan blowing outside air in from the hole in the wall the air conditioner usually goes. I'd like to have a couple of turns to absorb some outside noise. What I really want is...
  19. Forced ventilation from a window to cut out the noise

    HVAC
    So I live on a busy street with lots of polluting cars and buses. Wouldn't it be grand to build a duct work system from the window into the room with a few turns, perhaps a muffler of some sort to block the noise, then a quiet fan with a Hepa filter at the end to filter city air pollution. I...

    Electrical
    So I have a sub woofer connected to a stereo receiver, which is connected to a Cox Communications cable box via HDMI. At the old house I had no issues at all. At the new house, the instant the metal on the cable line contacts any metal on the cable box, the sub begins producing a loud tone...
