I have never heard this before today in the extreme cold weather in Texas. You just saved me a call to an HVAC tech!

Thanks for the video, we just bought a house with a heat pump and I never knew the sounds they made. Now if the installer would have put the outdoor unit someplace else besides my bedroom window it would be perfect lol.

THANK YOU!!!!! simple demonstration, Direct and to the point!!!

So very helpful. We recently moved and our new house has a heat pump. I’m not used to this at all, but glad to hear it’s normal noise

Thank you very much for this. I just had a heat pump installed back in March and I've never heard it make this noise. It made me think that it was broken somehow. Now I know what it is. Thanks!

Very informative. Thank you for the video!

Great video, finally found a video that made the same noise my heat pump was making at start up.

Thanks for posting this. Very informative.

Thanks much for this video! Very helpful in understanding the heat pump operation and the odd hissing noise I heard this morning.

Thanks, this was very helpful!

thank you, this was super helpful!

Thanks for this video! Was wondering about the loud sound.

Thank you for the video. It was very informative. Mine is making that buzzing sound. How long should it run in the defrost cycle? Mine seems to last a long time. It seems it is doing more of the defrost cycle then actually turning on. It does kick in at times but most of the time when I check on it, it is making that buzzing sound.

Wow. Thanks! Ive been quarantining in our spare room for a few days now with our heat pump outside the window. It’s below freezing here at night and this has been driving me freakin nuts. Neighbor owns an hvac company but I didn’t want to ask about it. Ours is a Goodman we had put in a few years ago, it’s loud when it does it. My closest neighbor has the original unit (20 years now and looks it) but I don’t hear his doing this.

Wow I always wondered what that sound was. When its 20 degrees out every heat pump in my neighborhood makes that sound it's like a symphany all night outside 10-20 going off at anytime lol

Thx! Put my mind at ease

Thanks for sharing

Thanks for the help though I might have a problem

Thank you!!!!

THANK YOU. Just bought a house and I’m questioning and researching everything before the warranty ends lol

Thank you for this, I thought my unit was blowing up or something when I heard that noise. Lol

Thanks

Good to know... I wish I would have know that this is a normal sound before today... just spent $99 on a diagnostic call for them to tell me to look at this video. 😡

is there a way to bring down the loud ass buzzing noise? Mine does this upon start up. and in defrost mode. and it's driving me and probably my neighbors nuts. it wasn't this loud a year ago. I just purchased a sound blanket to go over it. haven't installed yet though. Just wanted more info on how to attack the problem from multiple angles while i have the system open.

Please tell us: Is there a brand that does not make as much noise? Also, why can't the unit shut off, turn to defrost (reverse the valve), then come back on for the defrost cycle. Wouldn't that make the sound less? Like putting a car in reverse while doing 55 down the highway?

I don't consider that level of noise acceptable in the tightly packed urban houses typical of many UK cities. Is there anything that can be done to quiet these down? Background, I did see a recent reference to a Heat Pump fitted to a Bath (in Somerset) industrial estate without planning permission which now needs noise barriers to be fitted after the neighbours complained. Would welcome a video about these sort of barriers (i.e. how well do they work, what do they cost, do the trap cold air near it and so reduce its efficiency and so on)

Ours is only 3 years old, and on the first winter it makes an excruciatingly loud sound that sounds like Godzilla screeching. None of our neighbors’ units do that, and they have complained and are now angry because the noise is sharp, abrupt, LOUD, and screeching. I’ve never in my life had this issue, even with extremely old units. We’ve basically made enemies of our neighbors because of this. On top of the noise the heating system doesn’t work at all when temps reach 32 and below, and the air coming from the vents in the house is as cold as an air conditioner. The temp just steadily drops until we end up wearing jackets and covering with blankets. We are always told all of this stuff is “Normal,” and i know not a single soul that has experienced this and say the unit needs replacing. They keep replacing everything which fixes nothing, and they’ve had to replace the thermostat several times a year, and the breaker keeps tripping. If ours made the sounds like in your video, it may be easier to deal with, but our neighbors’ units are so quiet you can barely hear them... and they would still complain. 3 years of dealing with this on a new system... without any resolution or fix. So frustrating, and miserable in winter.

Thanks we got a new unit and were tripping out over that sound.

My heat pump scroll compressor makes that intermittent buzzing sound in cooling mode when it gets over 105+ outside. Sometimes an occasional and repeating tick sound emanates from the compressor when high ambient temps occur. At night time when the temperature drops, it sounds normal and quiet with the fan noise more noticeable than the compressor. Is this normal?

Are they all this loud? Thinking about getting a water-water heat pump.

Mines making a weird honk noise. Or a noise you hear when you open/close a water valve really fast. It’s loud to.

Had a customer complain of a motor like sound coming from her condenser at night. I'm in FL and it did get below 30 a couple nights. I think this is what she was hearing

Goodman Emerald series?

thats why i went with a regular ac unit the compressor works year round on heat pumps and i hate those noises

Ours make a honking sound with the compressor noise as well. I'm wondering if the pressures are too high?

Would be helpful to know if heat pumps making extremely loud "honking" noises is normal every time the heat turns on/off. Ours is loud enough to wake me every time.

Hi Jerry, just curious how loud the pressure hiss should be. When our heat pump goes into defrost the hiss noise is sometimes between 70 and 80 decibles. It wakes us up a few times per night. Anything I can do to fix that? It has done it right since it was installed a few months ago. Maybe installed wrong? Not enough/too much refrigerant? Thanks!

Damn....that is LOUD!

I feel so sorry for the neighbors to hear all this noise coming from this unit. What a horrible idea.

how often should ot go in and out of defrost on a daily basis?

That is the sound ours makes but only in the winter.... is there a fix for this?

Omg, mine is right outside my window and does this routinely at 5am (hence, why am writing this now 😩). Wakes me up!! Is there anything that can be done?? Unit is only a few years old😕

Can this be heard behind the wall from inside? I suspect this is the noise I'm hearing inside my bedroom randomly.

I just had an old unit replaced with a Goodman, it used 3172 kwh in 2 weeks. What would make it do that? It ran 24/7 and I had the thermostat set at 68.....

? When the heat pump does this make the the heat pump go into emergency mode that what it show on my thermostat in the house.

Why would I hear that noise in the late morning when I never used my AC? I just moved into a home 3 months ago. Never had a heat pump before until now, and been hearing this noise now and then. But it sounds as if it's coming from the opposite side of the house that the heat pump is on!

Wow screw that. My neighborhood already has enough noise.

What??????? I missed what you said after about :57

I have never heard a unit make this kind of noise.

So that loud noise is the beginning is normal

Its verry loud compre to panasonic

Worse noise ever when your trying to sleep. My neighbors heat pump turns on every 30 to 45 mins driving me crazy. I hope they could remove it and find a quieter heating system. I live in the hills and having this machine next to my window feels like I am next to machine shop with a steam engine train arriving every other hour noise it makes every time it shuts off.

If you want to make it by yourself just go to inplix page.

😨

Got two huge units in our garden. The noise is terrible. The entire 3 story house vibrates at night. Extremely annoying. See no future for these.

What a horrble sound. Poor nature. Poor birds. Poor you...

Dont bug your neighbourg .Dont buy thermo pump.

,gv

No kidding. How can you deal this noise? It drives me nuts just watching your video. It is a disgusting sound. OMG, it is worse than I thought. I choose solarpanels.

Thanks for the video my unit doing exact same thing. I’m stressed out,thinking something was wrong.
