How To Check Air Conditioning When Ac not working - Blows Hot Air (DIY) 

TFW you're looking for A/C repair videos and you see the Warped Perception guy.

*So amazingly quiet and **Fastly.Cool** in my room! 42db is at a whisper level. I bought 2 and installed myself.Very sturdy bracket and easy to adjust to fit windows of different size. Absolutely fabulous units!!*

Brother, you just saved me $125. Three weeks of gas, a week of food, some new school clothes for my kids. Blessings to you.

I know this is a 7-year-old video, but this just saved me from a $90+ service call that was 5 days away. The vents were blowing out "luke-warm" air, and all it took was pushing the fans in the condenser and the air is back to normal! Not sure why it randomly happened now since it's the beginning of July, but regardless I'm grateful that a free RU-vid video was all the help I needed!

This guy's go straight to the point. He doesn't waste time like other videos that I have seen. He gets straight to the point. I learn more in his video then my teacher of hvac. THANK YOU BEST VIDEO EVER

Several days ago only hot air would come out. I called out an HVAC guy and paid $320.00 to get my AC fixed. Then a couple of days later my second unit did the same thing. Now I'm thinking, "Did this guy sabotage my second unit?" I know, what a thought. But for both units to go out within days of one another? Anyway, this time I went to You Tube University. I watched your video and a few others and was pointed toward the capacitor. I followed your instructions, and now $28.00 later and the time and gas it took to pick up the part, my AC unit blowing out cold air again! I'm not mad at professionals who make a living off of customers without the knowledge or time to DIY. But I am immensely grateful for people like you who graciously, and so competently, make knowledge available so people with the time and inclination to DIY can do so. $320.00 vs $28.00 Incredible!!!

Dude, I'm not exactly sure when the outside fan kicked back on and the ac started working, but it's working - thanks a million!!

You already saved me a lot of money. I was able to make a quick diagnosis based on your instructions and with a new thermostat, I was up and running again. Thank you so much!

This types of videos are what RU-vid should mainly consist of.

The design makes this AC a possible alternative to ductless DYI systems. It works great. The remote control could be more visual aid oriented like a backligh design. Is impossible to see the lcd at least for me. Easy install ru-vid.comUgkx_hHgTlzH3uk31Fe2RVS3xEbXHGaN_z5Tation. Came on time . Great comfort around the house 5 🌟 again. Follow mfg instructions for care and all and this should be the only AC you need for those of is that don't live in new homes with central AC

I learned more here than in 25 years of asking questions to HVAC techs who have come to my house. So great to see a person who talks honestly and tries to help others, especially during these times. Many thanks. I would hire you in a skinny minute if you lived in my area. Bravo sir.

Woke up at 3AM on a Sunday with the A/C out. After getting over the initial shock and drying off from a pool of sweat (gross!) I stumbled across this video. BEST VIDEO EVER! Took me step by step on diagnosing the problem. Couldn't believe it was the capacitor (flex capacitor, lol). Got it fixed the next day and cooled the house down. Saved hundreds of moolah. Thanks bro. This was really cool (no pun intended - well maybe a little).

Thank you sooooooooo, much!!! I left the house for 20 min and when I came home it felt like a sauna. The thermostat read 82° and I started freaking out. My problem was the compressor fan. A small push and it started right up. Again THANK YOU!!!

You. Are. AWESOME! Your concise and easy to follow troubleshooting steps made diagnosing our problem really simple! It ended up being our capacitor that went bad. It only cost $12 for a new one! Soooooooo glad we didn't have to pay someone hundreds to replace that for us.

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Today was the first day I tried my A/C I've "had my A/C on" for 6 hours, and the temp. went up to 84, from 80. I was able to diagnose and fix my issue, I can feel the difference already. You are amazing and I appreciate you so much.

How are you the only one to show the paperclip test? Brilliant! Solved !! Thank you!!!

THANK YOU THANK YOU THANK YOU!! You saved me so much time and trouble. My air was still running, but stopped blowing cool air. After checking the temp of the 2 tubes going into the furnace, I checked the outside unit and found the landscapers had severed the thermostat wire. I simply had to strip the 2 wire ends, and re-attach, and it worked. Thank you for the great video!

the best video i have seen so far on diy ac guide. Thanks for making it quick to the point and outlining everything in between each section. Learned way more off this video than the last 5 or 6 combined.

Some people have a knack for turning a simple idea into a complicated 10 minute explanation....this video is just the opposite. Great job!!!

You just saved me a bunch of money. Here in Phoenix were going to have 101" temps this weekend and I have company coming in town and my air wasn't keeping up with the rising temps...I started troubleshooting...new air filter didn't help but cleaning the outside unit did the trick! Thank you!

Thank you so much, Matt! You saved me a service call. It only took a couple minutes to troubleshoot and now I have wonderful cool air blowing.

My fan was stuck! Thank you so much! My ac has been working intermittently, and of course when the repair guy came out, I left work to meet him and walked in and it was a brisk 70 degrees in here.... so I couldn’t prove my issue. he checked all fluids, they were great, and tried to tell me it had to be the air filter (which I replace every two months with high micron filter for my allergies), yet it wasn’t barely a month old, and it wasn’t dirty. I knew it had to be something simple that I was over looking. Thank you for your informative, yet to the point video. I now know everything to check next time something goes wrong!

Thank you. You just saved me some time and money. After watching your video, I cancelled my appointment, turned on the thermostat and it works. I'm going to clean out the filter. Thanks again!

Thanks SO much for the video. My wife and I just bought our first home, and never dealt with AC units before. Turns out our fan was stuck. Used a knife sharpening rod from our kitchen set to get it going (night time so didnt want to go look for a stick), gave it a good push and now its running (scared the hell out of me when the blades started turning and hitting the sharpening rod - lol). Thanks for the help!!!!

Thanks for the prompt response. I upgraded the thermostat to digital a couple days ago. The whole system is at least 7 years old. That's how long I've been living in the house and I've never done any work to the AC unit until now. I will try what you suggested. Keep you post

I watched this video from start to finish and it helped me a great deal! We had recently moved into a new home and was wondering what we got ourselves into with respect to the HVAC system we inherited. We thought maybe the insulation in the attic is THAT bad that the 2nd floor felt like a sauna on a summer night, or that we were doing something ridiculously stupid like not knowing where the "on" switch is to help the adjustments we were making on the thermostat actually happen. I went through the checks he had described from the basement inside the home to outside. I went almost all the way through his examples of things that could be going wrong. I soon discovered that my problem was that sometime before we had moved in, an animal had chewed through electrical wire running from the outside unit into the home. It was an easy replacement of a short portion of wire that resulted in my system running as it should! I am thankful to have watched this video and appreciate the help buddy!

You were so helpful! We're retired, and watching this video saved us some money. Just the simplest thing I saw on this video, we were able to do on our own. Thank you so much! You should teach a course in this, you're a great teacher. Will go and buy those 2 simple tools. Thanks so much! You're the best!

thanks on the response. i called a tech and he ended up putting two pounds of freon and since i helped with the tear down and assembly cause i wanted to learn, he only charged me $112. I thought it was fair. It was hot and we had an abnormal sight of an infestation of killer mosquitos in the area. So, between the mosquito bites, and our sweat I think we did ok. We couldn't find the leak though? He said that it might be too small to see. I asked him if there was a color die but he said that my unit is too new and would not work well with anything but the right freon? I am not sure on that explanation but I was happy that I had A/C. Thanks for your info, it helped a great deal. GE.

You showed me some good techniques to resolve a/c not starting issue. You are the best. Thank you very much.

Thank you, thank you, thank you! You saved a hot, pregnant woman in August! Also, I know you saved us a ton of money. It was the breaker. The house is up to 85 degrees but hopefully we will get it cooled down before bedtime. THANK YOU!!!!

awesome vid, it help me a lot, the most thing that I like it was the comment in front of your beers, " If I help you, you help me" I always say that, if you help me I help you back no matter what, thanks ...

You have done a very good instructional video. The step by step instruction was explained in a way that even high school kids could understand. It is 80 in our house with a 4 year old and a 8 month old and the temps are supposed to get in the 100s. Just watching your video I can figure out what is wrong. Thanks greatly

Thank you i been in my house cooking for two days followed your steps and my ac is back blowing again thank you!

Dude I really think you just saved me like $200 dollars! Thank You so much for breaking it down.

My fan wasn't running. The stick thing actually worked. Thank you!

Your walkthrough was one of the best explanation for troubleshooting. If it’s a wiring disconnect with the Rama stat and ac unit what’s the process to fix it? With Covid we really don’t want people in the house, other than the basement

This is one of the best videos I've seen on Utube. Very useful info. It saved me an expensive service call - which helps a lot when you are living on a fixed income. My problem turned out to be the condensor motor was seized. I gave it a good push, and viola - it turned on and is now cooling down my house. Thanks again, I've subscribed and I'll be checking out the rest of your videos! Keep videoing.

You are AWESOME!! I've been troubleshooting all day in 90 degree weather so that my husband didn't have to come home to a hot house after working in the sun all day. I wouldn't have figured it out without this video. At first I was like, "rims what?", but you explained it better than anyone else so far and I FIXED it!! It was easy, too. BTW, NICE RIMS!!!

My fan wasn't working and I moved it with a stick like u said and bam. Thanks , u saved me some time and headache for my family

Thank you! Our AC repair guy said it was dirty coils and charged $160 to come out and spray cleaner on coils and wash air filter with hose. Sadly, 84 degrees later, still not working. He's coming back in the morning.

Thanks Man! Saved us a service call. Also, I always wondered how these things worked. It never clicked in my head to check the blower/furnace filters. Cheers!

great diy ac guide, not sure I recommend but if you really want to do it, this video is awesome!

Wanted to say thanks for the video. It was short and to the point. Our A/C stopped blowing cold air---on the evening before supposedly the hottest day so far this year---and I was able to diagnose it down to a bad run/start capacitor with help from your video. Hopefully I can source a replacement locally tomorrow.

Thank You for your video. You are spot on and fortunately my problem was in the 70% looks like I need to get a fan motor start up capacitor. I appreciate the time you took to make the video.

Nice and simple and clear video thanks it help me a lot. Now I got to call because there is noise in that line you said.

Thanks for this video! you totally saved me a service call and the money they would charge me to get the condenser fan rolling again. Tool of choice...Stick... Thanks again!!!

Very informative. My AC not blowing cold air, will try some of your troubleshooting tips.

OMG super great video I wished you were located in Texas as the techs here seem to not know what they are doing. I've had AC issues for two years now. This video makes me wanna troubleshoot the issue myself but unfortunately I reside in an apt.

FYI We had our AC running but it wasn't' blowing cold air we found it was the circuit breaker labeled Dryer "Reciever Dryer" and it was switched off. Thanks to this video we checked that circuit breaker and saved us a service call!

The best video I've seen for this. Thanks. Easy to follow and straight to the point.

I used your video today. Thanks for the help. ~single mom who fixed her AC.

Thank you, I followed your steps and found my fan not turning. Not sure yet why it stopped but started when I gave it a push. But this is not first time running it this season,

I just like watching these repair vidios just incase something does go wrong, thank you for putting this info in the eather

A DIY gem, helped me solve my A/C problem is a flash. Thank-you.

You saved the day!! I was able to get air running in less than 10 minutes!!!

Great video! What should I do if my suction line is warm?

Thanks man you helped me so much now I have cold air again!!!

Awesome & thanks and have a Bless day!!!💙🙏💯💯💯👌

thanks, that was really thorough, well thought out and very helpful!

I just watched this video and it was super helpful-saved me from calling an emergency AC guy (for tonight at least). Thanks for sharing such useful information!

Thanks man now I can act like I know what I'm talking about when I call out the tech. Low on refrigerant hissing liquid coil Thank you again

Very informative and precise. Thanks. BTW, they call it a "11 in 1" because they count the two ends of the shaft which hold the bits as socket drivers.

Thanks for this, went outside and gave the fan a nudge and I'm no longer sitting in a puddle of sweat

My brother you are amazing thanks for the very detailed and simplified explanations. I feel like a more confident tech now thank you. God bless.

great video... U explained thing's very helpfully. Thank you

I just want to thank u a lot because you saved my ac. Thank u sooooooooooooooooooooooo Much!!!!!!

Thank you for this. I believe I found out what the problem is with my AC. Just to verify, if the copper tube is cold what does that signify? You said it has to be warm to the touch? This is with my account running and everything seems to be functioning. The air blowing is cold but not cold enough to what it is set to. I do hear hissing which could mean low freon from what you had stated but just want to make sure

The best video with simple walk through. Thanks

Great vid man. Straight forward, not a lot of unnecessary jargon. much appreciated (I subscribed too) Awesome job!

Wow!!! You Rock!!! Subscribed immediately. U should be a teacher. Excellent video. My mind stayed hyper focused from beginning to end. (That's a first ...trust me.) Cant wait to share your video. I'm gonna help alot people who cant afford to be ripped off... thanks to u. Thank u sooo much. Many Blessings from Florida. :)))

Awesome video ....quick question. I have only one unit in my home and 2 thermostats on each floor. No issues on first floor. But no air comes out of supply registers just on the second floor when cool cycle is on. Any suggestions ?

Great direct and to the point. Thank you so much

You're awesome! Your explanation was to the point and the house is cooling off!

Thank you very much for your help. I was able to fix my AC with your instructions and it worked. May God bless you always!!!

Great teaching! Simple and easy to understand!!!! Where would the condenser located with high-rise building?

This is the best video by far! Every possible scenario was covered. I was lucky enough to go through all of them. Thank you. Without a doubt, a thorough explanation and right to the point. Thank you sir. I will subscribe and recommend you to others.

Thanks! You saved me a late night service call.

You're the GREATEST man! Looks like my capacitor is shot, you helped alot. thank you from Canada

Thank you! It was a dirty filter and tripped breaker!! You are awesome, thanks for putting such a helpful video on RU-vid. :D

Thanks for this video sir I am a Hvac technician here in Dubai UAE

God bless you man. Keep being humble my brother 👍

Outstanding, informative, thorough, and professional! Thanks for sharing your knowledge.

Hey, great video. I followed your steps. I am getting the hissing sound but the other line is not cold at all. Unit comes on fine outside fan blowing well. I did change the compactor also. Could this be a contactor issue? Air is coming out of vents but not cool.

It would be great if you could include the capacitor. I was able to get my fan to run by pushing it but the compressor still would not start. I took out the capacitor and tested it with a ohm meter and it was totally dead. This is still a great video and was the main one that i used to fix my A/C. Thanks!

just saved me time and money I kicked started the fan and BAM!! started right up

Nice trick doing the jumper wire. I usually just tap the contactor with something plastic. But the issue you said at the end.. its not a capacitor for home systems? Its funny cause I work on commercial systems the most and well (even though I am still a rookie I am learning from licensed masters at my job and plan on going to school soon). Now if the fan is blowing cool. And tstat of course is in auto and working usually its a wire issue. Bad relay or a cap. I find bad relays but tapping the contactor to see if the compressor jumps.

Right to the point, well condensed ac guide. Thank you!

Not all heros wear capes. Thank you!

very helpful video.thank you sir , now I have a question my indoor unit and liquid line sound like liquid flashing before entering the piston metering device. and my succion line is not cool (room tempeture)

thanks to this video just fixed my air conditioner. thank you!

Wonderful educational video. Thanks

Pretty fabulous video my friend! I'm pretty novice to the a/c maintenance and this is about straight forward as can be! I like you sense of humor to man! Thanks for all the great advice! Hopefully I'm done after a new filter.

Thanks!! fixed my problem. The maintenance worker forgot the disconnect breaker out

hi thanks for upload very knowledgeable video one of the best learning video i saw i m a beginner ac technician can u pl z recommend some book or programmed to become master troubleshooter in hvac .thanks in advance

This is an excellent video filled with expert knowledge! Thank you.

Nice walk-thru troubleshooting! Thanks!

I rocks with your channel 👍🏽

great job of explaining

Great video. Very helpful. Thanks

Thank you great step by step video we’re going to check our air conditioner gt
