[@lenmurtha8324]

I want to personally thank you for the video. It saved me at least $500 according to one of my HVAC friends. It took me 5 minutes to remove the capacitor and 3 minutes to install the new one. Everything working beautifully.

[@HephaGlowMinisDG]

December 24th! Heater broke yesterday. 10 Degrees last night. I searched and searched until I found this video. After troubleshooting the inducer I found this capacitor video! It saved my family for $4.00! Replaced this piece and everything fired up again. Thank you!!

[@joanncard8836]

This is one of the best videos. Even if I cannot fix it myself, I now know what a service technician should be telling me.

[@Enn-]

Thanks! This vid helped me ensure that the sound I was hearing was what I thought it was. The capacitor cost $3.70. I had a friend pick it up on the way over. They were happy to help, and refused to accept my payment for the part, as I didn't charge them for lunch. Likely saved me $300-500 for a service call to get it fixed, and was solved before I had my morning coffee, rather than waiting a couple days in the heat for the repair.

[@XxAerykB13xX]

This single youtube video solved my AC fan problem for 3 dollars. Bro you are a life saver!!!!

[@chrisscott8003]

This is exactly what my carrier furnace was doing. It started squeaking the day before it started humming. Ordered the capacitor on Amazon and in 2 days and $10 later my issue was fixed. Thanks so much!

[@eriknoyes]

Dude, if the $14 capacitor fixes my issue, I’m sending you $100. Still saving ~$185 off the first hour quote by local HVAC guy. Amazon delivers tomorrow. I will follow up. Your videos are great. I am a handyman who leans on you for the real deal. You never fail to bring good and cautionary advice. MUCH appreciated out here in the City by the Bay.

[@daviddavis3504]

Did it work?

[@eriknoyes]

It didn’t, but I cleaned the contacts on the old capacitor while I was at it and tried again. The first time using it in months, it buzzed for about two minutes and then fired up. More info: I couldn’t find the same size capacitor although I found a bigger one with the same rating. Be prepared to remount your new one in a different bracket.

[@DPCPhotos]

Dude!!!! THANK YOU!!! My capacitor finally failed today, did a search on YT, found your vid, picked up the part at a local ACE Hardware and had everything back up in running in no time. Took an extra hour to clean the fan/blades/intake/etc... Super quiet on start up and works great! Thanks again! 😎

[@EverydayHomeRepairs]

Nice, my local ACE didn't have a selection of Capacitors but I did see some location about 2 hours away did. Pretty handy having ACE stock common capacitor sizes 👍

[@blahblahblahblah-r9i]

Thank you so much! It's a weekend on a cold day just before Christmas. Heard this same noise from the basement, HVAC is dead. Watched your video, was able to determine the ace hardware near me had exactly 1 capacitor in stock and is about to close. Made it within 10 minutes of close. From finding the problem, to finding your video which led me to quickly diagnosing and finding the part I need, I had everything fixed within 60 minutes and $13 later after tax. If I had to do an emergency call on a holiday weekend you saved me many hundreds if not a thousand bucks in my area. Not to mention at least one cold night to get through if I wasn't able to resolve quickly. You're a savior!

[@NandyF50]

Just fixed my 20 year old system that went down. Thank you. Cost us $10. Still replacing but we can survive the heat till the new one comes.

[@quangtruongnguyennhat9249]

I am coming here to thank you, the part only costs $12 and you saved me before the winter storm comes in!

[@graememcintyre5794]

Wow! I just bought my 7.5/370 for 6 dollars Canadian and solved my issue. I can’t thank you enough. I’m sending super virtual thanks and drinks in your general direction!!!!!

[@miguelh2481]

Thank you for teaching people how to discharge them properly. Those things hurt when charged. Please exercise a lot of caution when messing around with these items.

[@FirstGirlofFive]

Thank you very much, the sound, troubleshooting and step by step was spot on. Also thanks for adding to check with Amazon, next day delivery and 20 minutes of work saved us from living a week with an 80degree interior home temp waiting for a ac company to come and service it.

[@flower-the-earth]

Perfect video. The sound was helpful. Found the component locally. Fixed! Thank you

[@ohdeerme]

Thank You for your video. It was my problem, and my furnace and ac are working again. Do yourself a favor and keep an extra one on hand by the furnace for next time you need one. You will be glad you did !

[@j.speedsvids2646]

Thank you so much for this great video. I came home to an 85 degree house this evening. I had it fixed within half an hour thanks to your video.

[@liveshaker]

Thank you for this! So helpful to hear the sound, which is exactly what I’m hearing from mine. Looks like it’s DIY time! Your video was the most efficient and effective home improvement demo I’ve seen. Top shelf!

[@Doolz51]

I’ve had this issue for months and could never find an answer. Thank you so much. It would always turn on the first time, but would never keep the temp regulated. Now it’s 55 in my house and I have 2 toddlers. So hopefully I can find a part soon.

[@jc691]

Really glad I found your video. Woke up this morning to a cold house, after some quick research/troubleshooting and a $10 part I now have the heat back up and running, thank you for helpin us all try and save some money. I appreciate it!

[@russkaye9178]

Thank you buddy you saved me money I just couldn't afford right will recommend your channel to anybody who needs it

[@etripp111]

Thanks so much Scott. Our furnace went out on a Saturday night this November. After watching a few videos on why the furnace ignited but the blower did spin I found your video. Thank goodness I did since I was ready to order and replace the blower motor. For less than 10 bucks I ordered the capacitor. It arrived in 2 days and was a 5 minute fix! Thanks again for all your videos.

[@lisasteiner9793]

Thank you for this video! This totally helped me fix my issue. First the capacitor and then I had to replace the blower motor. Not too hard, just had to wait for the parts

[@volleyballurrrr]

I have been trying to find a video breaking down this failure mode, I have a wall shaker AC with these exact symptoms. I was relieved to see your video in my search results, I have learned tons from your other videos so I knew this would likely be what I’m looking for. Did not disappoint, I’m no longer sweating my upcoming repair.

[@redneckrican7873]

Worked for me!!!! Took a while to find the capacitor, it was hidden on the back of the fan housing out of direct sight, luckily I saw two wires going back there and then felt around with my hand! LOL Was an old 1970s Bryant model. Changed the cap and the fan started right up without the drawn-out groan. Thanks again for this video!!!

[@lawdog516]

I also have one of each (dual run and run capacitors) on my shelf ready to Install when needed. I like B.M.I. Capacitors because they are made in the Great USA, I’ve had bad luck with that Chinese junk, hope this helps. Thanks for making this video and PLEASE don’t forget to DISCHARGE the capacitor your removing !!!!!!!!!!!

[@rumblestruttersmith3666]

Excellent video. Mine is currently making that noise on heat and air. Unfortunately, I'm not physically able to go into the attic and do it. At least I know what my HVAC guy should be talking to me about. Thank you.

[@jotice9]

I thought my motor was out again; just installed a new one in 2021. The manufacture date was August 2020 on the capacitor that I purchased with the motor. This video did help me determine that the problem was the capacitor rather than the motor. Thank you!

[@Wonsdloc]

Just had this issue happen to me. Went to youtube and your video popped up first. Thankfully. This was my exact issue and thanks to your guidance. I had it fixed in 2 days.

[@KaspiansTravels]

I'll add mine to the pile--thanks for this! $30 Amazon rush delivery for the part, here it less than 3 days, a half-hour of work, saved me probably $400-600. I did notice, when it was buzzing, if I reached in and carefully gave the squirrel cage a spit, it would start up--no resistance in the motor itself. So, I knew it was capacitor. Warning: Careful if you do that you don't cut your finger off!!

[@LucasScottMusic]

You just saved me like $200. Thank you. Got the part off of Amazon, arrived today, changed it out, now my heat is working again.

[@EverydayHomeRepairs]

Boom 👊

[@e-5ruben807]

Yesterday was July 4th and I turned on my A/C and the blower was not working. So early next morning I went out and bought a new capacitor and it fix the problem $6 part. You saved me a bunch of money. Thanks for the excellent video. 👍👍

[@burpelson]

Spot on assistance with this video - Mine made exactly that sound, and $16 later plus a trip across town to get the part had my furnace working again on a cold day. Well done and thanks!

[@NachoBiz545]

Omg, I've been searching for a helpful video and this is it. My furnace is making this sound and I had no clue and other videos weren't helpful. Now this might be the reason why my furnace is making that sound, tysm!

[@EverydayHomeRepairs]

You bet, best of luck troubleshooting. Be safe and keep warm.

[@DerongZhou]

thanks to this video my house is warm again, saving me cold nights but above all money! thanks and God bless!!!

[@scatboychan6143]

God bless you sir. Came home to my girlfriend saying there is a buzzing and the AC wasn’t working, found this video and it immediately helped. I am in no means a HVAC technician, but a 7 year old could do this job. Super simple, unfortunately had to go a day with AC because I had to order the capacitor online since no local stores had them, but it came the next day and BAM, im a certified HVAC technician now😎 jk, but thank you very much, keep up the great advice❤️

[@stevebaldwin3187]

Thanks for this video. The walkthrough was very helpful especially the buzzing at the beginning indicating the same issue. Found the part at Ace for under $9. AC back on. Thank you.

[@billyengler5534]

Good info. My system is making the same noise and nothing is blowing through it so I figured it was the blower motor. I'll for sure try your fix first!

[@disnalee]

My blower fan isnt blowing air into the room. You can feel the heat but no warm air blows. Furnace sound like my furnace.

[@losmoore3358]

Mine did that same humming sound and kept making that noise even when unit is off. Capacitor was bad like u said. Hoping that's it. I ordered the part thru Amazon. I have been out of the game being a Heating and air tech. This was a refresher. Thank u.

[@joegoodman9232]

Ok all done! Great easy fix thanks to you. 3min total.. Luckily I had a Granger's 1 mi away. Great and efficient Co. Service was good and the price $6.47 ! Not Bad. Thanks again! Time now for a cup of joe and some ABBA..

[@kylejacox]

Thanks for the video, my furnace was making the same sound. Glad I found it on time. A parts store had the part for only $8.00.

[@ItAintMeBabe99]

Yea, My thieving HVAC company, in my area, wanted $314.00 to replace my dual AC capacitor. I bought it for $7.20 and replaced it myself. Should be a law against this type of price gouging !.

[@franknorris5422]

Having just basic knowledge sometimes can save you so much

[@disnalee]

Omg serious. The serviceman wants $2000++ to replace my thermostat, board and labor cuz my furnace does not blow warm air into the room.

Dude you saved me a bundle. Had same issue and happened to have a capacitor from the previous AC and just swapped it out. Thanks

[@EverydayHomeRepairs]

Nice! Saving time and money is the name of the game 👍

[@markh3478]

Thanks for the video .Especially the discharge reminder. Mine quit when we are having 100 degree heat and its in the attic so its 120F up there and I'm old. Its a short term fix but I went up and banged by hand on the cover . It solved the problem but the system is 35 years old so at least a new capacitor is in order. Local HVAC place have them in stock for $10. Other tell tale sign is "cooling on" flashing on Honeywell thermostat just below actual temp display. Will flash when blower fan not acting on call for air.

[@catatonicbug7522]

Here's hoping! I just ordered the replacement capacitor from Amazon with next-day delivery for less than $8 with tax. Much better than a $300 service call and time off work to let the guy in.

I thought this was my problem, my unit would buzz just like in the video or it would turn on, run for a minute and then turn off and buzz. The old capcitator was jumping all around on the meter so I replaced it. Still doing the same thing. Fantastic video nonetheless!

[@willarddickerson921]

Check if you are getting clean power to the capacitor/fan.

[@genegarber8332]

Not replacing batteries in thermostat cost me $500. Air handler stopped blowing completely but was humming and froze the inside and outside unit. It's under warranty and ac tech replaced blower motor. $310 for labor $97 for service fee and $90 for refrigerant. 2 days later it wasn't working. On a hunch I replaced thermostat batteries. Instantly the system was working fine. No problems since. I hope this helps somebody out there.

Thanks so much for this video. I just pulled my capacitor and it only shows 1.5µf on 10µf capacitor. Bought one at Grainger 5 minutes away from me for $5 and change. Hopefully this solves my issue. Update: Yep, replaced and it's all back up and running.

[@TheKitsuneDen]

Thank you, I was going to school for HVAC (epilepsy stopped that 😞) but I still have all my books and stuff- I had the same problem with my Rheem system, and I have replaced the capacitor (the first thing that came to mind, plus it was a cheap replacement...) and then I couldn't get the whole system to start. I started to dig through what could have been going wrong, the hum was going still going on- the circuit board... I don't have to replace the whole thing, or just which part (haven't found it yet... I still have to check it with my meter) Sorry this is so long ago of a question, but I'm completely lost on this.

I have had this sound going on for over a week, I legit thought it was my fridge making the noise. It wasn't until I went into my basement today that I realized it was my furnace. Looks like I may be out heat in a Canadian winter, not looking forward to that! Serves me right for not checking the basement, but It's a dirt floor basement and I never go down there except maybe once a month. I hope I didn't damage too much!

[@lilartroom]

The tech had already replaced the capacitor, and it's still making the humming noise. It seems to do it when the temperature drops. If I turn the unit off and turn back on when the temp outside is 42 it seems to work.
