I love how he gets right to the point and you don't have to try to skip ahead to locate useful information. Some of these guys think we have nothing better to do all day.

So helpful hearing the sounds associated with each issue. Thanks for taking the time to shoot and post this video. I'm relieved to learn that the popping sound is normal.

This has got to be one of the best Youtube videos I've ever seen on diagnosing an issue. Very clear language and sound samples (I very well may have a belt issue). I've been around the Youtube block for a long time and have uploaded my own DIY videos. Great job AMRE Supply!!

Great video! It helps to hear the sound associated with the problem description and solution.

[magnoliablanche]

Thank you for adding in the type of noises for each problem! I found this video very helpful for my untrained ears!

[levileroy]

Thank you for the video. Disassembled my fan cleaned it up and tightened all bolts and set screw, put it back together and everything is running great. No shaking or noise.

[seane]

This was amazing, mine sounds just like the loose bolts holding the motor, ty!! You're nothing short of an angel :)

[lesliefairley]

What a GREAT video! Thank you so much for taking the time to do this! Single mom here, so it really helped that you included the sounds! I’m about to strap on my (pink!) nail apron, bundle up and head up to my attic to see if I can repair what’s causing the racket! I’m hoping it will just require the tightening of bolts! 🤞🏽 Stay tuned and thanks again! 👍🏽

Thanks for the hints. I just fixed the noise in my furnace by adjusting a few bolts. None of them was noticeable loose, but tightening all of them (including the blower) did the trick. Thanks!

I am so relieved to hear the banging my furnace makes is not a problem.. Thank you so much for your troubleshooting all furnace issues getting to the point. You could teach many how to do a successful video 👏 Have a beautiful day 🌞

I just moved into an old home and the blower was in a really disgusting and loud state. I cleaned all the bolts including the centre one mentioned here and it's making soooo much less noise. Thanks so much for the context here, working on furnaces as a homeowner can be daunting.

[KC-rymf]

This has to be one of the best videos I have ever watched! Thank you for putting in the effort.

[StudioMedia]

This is a great video!! Having examples of each of the sounds was incredibly helpful! Great job

[ethanhu]

Great video, answered my question of hearing knocking sound from the hole where air flows out.

[adrianr]

This is one of the most useful videos on Youtube!!!

Thanks for showing the location of the blower fan. I had huge grinding noise and as it turns out one of the sticker labels inside the furnace came off and got sucked into the blower making grinding noises. I removed the torn pieces of paper from the blower and the noise was gone. I recommend spinning the blower manually first to see if the noise come from there

[ajpasa]

You did a great job adding the noise sounds here, thank you!

[bmzevnf]

Best video ever! Clear and informative. My furnace fan sounds a bit off balance on the low setting. On high it smooths out it seems. Weird. Not sure what's going on

[DrunkenUFOPilot]

This is great! Sound samples are tremendously helpful. Here in NW Montana, where I woke up to -30F this morning, I really like when this thin-walled camper's furnace runs properly. But it does not always run well.

Sometimes it start off rough, wobbly or rattly, lower RPM, and no heat. After a few seconds to a few minutes the motor goes steady and smooth, just normal hum and air noise, then a few seconds later the ignition kicks in and I have heat. But sometimes it'll start off rough and stay that way no matter how long I wait, blowing cold outdoor air into my formerly comfy living space. Waking up to 40degF and a noisy blower at 3am is not fun. Maybe thumping the exhaust port or the main housing of the furnace will cause it to run smooth.

From other videos and articles I know about the sail switch, which explains why there's no heat during the wobbly/rattly phase, and it all works fine once the motor goes steady at full RPM.

So, do I need a new motor or could a bit of oil or some other cheap easy method fix this?

[tanedasmith]

Thank you, spot on..., had my wheel cleaned by AC company and that’s when squeaky noise happen .🤨🤨🤨. No, they are trying to act like I need a new system, NO I DONT... they have been servicing it for 5yrs. Yes my system is 20yrs old, but it kicks air and heat great, ☺️even before it was cleaned. Thanks.
