How to Fix an AC Unit That Blows Hot Air - HVAC Repair 

Be careful removing the capacitor, it stores electricity. You should always decharge the old and new capacitor before handling it. You can short it with an insulated screw driver common to herm and common to fan connections

Omg.....it really worked, its 94 degrees here and I got my 2 yr old granddaughter, you truly are a Life saver 🥰 Thank you 😇

Good video. I actually did this repair awhile back & it worked out great. One useful tip I would add is that before someone pulls the wires out of the capacitor, they should take a picture with their camera. Then you can easily see where everything goes.

Videos like this are why I love the internet.

Dude, I sincerely can't thank you enough. You saved my family so much money. Watched your vid last night, and just installed the new capacitor a few minutes ago. Working better than ever now. Thanks!

Thanks for this video. My AC was blowing cold air for a few minutes then warm air only. Tried your screwdriver trick on the fan and it worked! Just replaced the capacitor for $13 and its working great!

Wow.. Air at fan was blowing out cool air..turned unit off ..changed batteries.. Wait3d a lil while..turned unit on at thermostat and went outside and fan was blowing out hot air .. Its working but will check it again when it gets to the temp i set it to...just had a company to do ck up before it got hot..all was fine outside unit..so now i may buy a new thermostat..it is an old one.. If that doesnt work i will call company again..but right now it feels good..We are in N.C. too.unit was cleaned by company in May along with ck up but now i will clean it myself with Dawn!! Guy said coils wer dirty at the ck up..thanks for the info.. Happy to get cool air as it was hottttttt today ..and will be thru the weekend!!

I just got EPA CERTIFIED and plan on getting into the field. I am lacking confidence but videos like yours are helpful. Thank you.

I had vandals to keep messing with my ac till now it has finally quit cooling. Last time they took my sir out and went and scrapped it when I was gone& my roommate. But I let that one go.Because he has helped me.

I did what you said (didn’t replace the capacitar though) and it worked! I will clean it in the morning. Thanks!

Nice man got mine working! Explained everything in detail👍

Hey this fixed my AC thank you soooo much!! It’s 110 degrees where I live.

Excellent advice. We replaced the filter and washed the outside unit. Thanks.

My fan spins fine and I still have warm air. I pressed in the coolant valve and freon sprays out so I assume I have coolant in the system. What could me problem be

Hello everyone, It was mentioned in the video, but I just want to remind everyone to PLEASE make sure you connect the wires to the new run capacitor exactly as they were before. If the wires are connected wrong you may blow your fan motor or worse. Good idea to take pictures or a sure fire method is to label the wires b4 you disconnect the old/bad capacitor. There is also a run capacitor on the air handler unit inside the house that helps the blower motor start. It is usually the outside capacitor that solves the problem though.

Thank you!! Changed the Cap and we're cooling now.

What does it mean when the outside air is warm. But then makes a weird noise and blows cold. More weird noises then warm again.

Thanks for the pro-tips. I was able to get the ac working

Hi. My son and I got home and the air was blowing out HOT🙁😭😱The air comes on and the fan is turning outside. I thought it was all the bushes surrounding it; constricting air. We cut them all down, cleaned the unit with water. Nothing changed. I changed out the filter as well. Do you think it's the compasitor? Help! It's a GOODMAN..

Well I’m subscribed, you probably saved me hundreds. If not more. Thank you

Hey I have a question when my unit is pretty weird when it’s hot outside it blows hot air but when it’s cold outside it blows cold air how do I fix this?

Consider adding clean EVAP Indoor coil to your list.

Thanks for the video, I’ll give it a try. Although my outside unit sounds like metal hitting metal. I’m thinking it’s the capacitor because it cools for 30 minutes the fan stops buzzes and stops cooling the house.

Just fixed mine works like a charm!

Thank you. Awesome, $20 capacitor repair.

I have a 3 T goodman unit the tech replaced a " weak capacitor " was reading 38 instead of 45 so he said they Replaced it , had a newbie with him , a 40 cap for a 50 cap " new one " that was few weeks ago Today my Unit Is Not Cooling .... was it ok to replaced a 45 cap for a new one of 50 cap ? what do you think it went wrong ? thank you for your input 😎👍🏼 God Bless today is June 19 2021

The wink got me! 🤣

any idea why my ac blows cold air in the morning but hot air during night

Great video, Do you know if you could help me? I got the capacitor in with all the wires in the right spot but now I am only getting hot air to come out of vents. The fan on the outside unit is blowing out cold air. I think something is definitely wrong. I checked the cold pipe going into the house and it was hot. I turned off the unit and disconnected the power. Any thought on what I did wrong thanks!

What happens if your AC unit outside is turning what is blowing hot air also my air filter is dirty I’m gonna replace that now would that fix the problem the AC filter

Next step, dump the nest. lol. You should get insulated screwdriver and touch common then move sideways to touch herm and fan contacts on capacitor to discharge so you don't get jolted.

My unit is a wall hung BARD unit that was making a huge racket outside and blowing warm air into the house here in FL. It got to 94 degrees inside. The A/C company came out and said the fan and motor were bad so he replaced it, put a little freon in the unit and it worked, but it's still making a racket even with the new fan and motor, it seems to skip a little and you can see the fan wobble inside. They are coming tomorrow and said they were going to charge me for labor. I paid $575 for the first fix on Oct. 19th! They mentioned the compressor. I said that if it was the compressor, the problem was misdiagnosed. It's very cool in here and the compressor kicks on just fine. I'm wondering if I'm being ripped off or what. Any advice? Thanks!

I did everything u said. When I did the stick thing it worked. Got the fan up n running. But I finished the whole video so I knew I had to replace the compacitor. I got the exact same one. Replaced it. Was pretty easy. I put everything back together. Turned on the ac at the thermostat and walked out and it was making the same noise from the fan.... so idk why it didnt work this time... I even tried to use the stick method again to jumpstart it... but this time jump starting it isnt even working... it feels kind of hard to move... I even tried to turn it both ways to make sure I was turning it the right way... please help me.

THANKS! got my A/C back up and running! however, you missed one very important step... CONCUSSIVE RECALIBRATION! the damn thing wouldn't kick on until I banged on the housing hard!

Dude! Thanks man! Step 1 and it was the problem!

Hey bro GREAT VIDEO AND INFO!! YOU say you’re in NC? Bro I’m in Charlotte. How can I contact you? Thank you!!

GOD BLESS YOU FOR THIS VIDEO 🙏😭😭😭 I sent this video to my hubby n sure enough the capacitor was the issue!! He switched it out himself saved us hundreds of dollars worth of repairs n service fees 🥹

Seems like whenever it's real humid out in the morning my air conditioner will come on and then when it shuts off the fan keeps moving outside blowing and then it starts freezing up inside so I have to shut it off the breaker and wait a while sometimes I have to do this twice before it will finally come on and cool and shut off completely like it's supposed to without the fan running outside what is the problem please help! Otherwise it cools really good.

My fan is spinning but the is warm. Do you think its the compressor? And should changing the capacitor fix that?

Hey thank you this was very helpful.

When I start the ac, it blows cold air, but after 15 minutes or so, the cold air is gone and it starts blowing cool/warm air. And the thermostats never go below 75 even when I set it around 63. Do I need to replace something?

Your good work brother

So I changed my capacitor last June. Today, the fan and everything is working fine, but the air is not coming out as cool and it will not get to my target temp. Any thoughts on what it could be?

Very informative 👍

I'd recommend discharging the capacitor before removal.

Man big thank you! This fixed my issue

What if I do not hear that the unit is trying to come on? How do I test the capacitor?

I wish I could get you to come to Merced CA. I just got out of the hospital, on life support a bit so I'm not feeling like handling this but my landlord has refused to get anyone here to actually FIX my AC. 🥵😭

The pipe going outside to the ac unit in mine, is frozen, and not blowing cold air. I did replace the filter, I did clean the unit outside. Same problem still. The unit has not been tripped at the power panel. I don’t know what else to do.

My ac turns on fine, new filters, coils clean (living in fl I clean often) blower works good just not blowing cold enough air gets to 79°-80° no ice build up thermostat test was good not sure what to do.

I need some advise. My unit blows warm air when its very hot and I am forced to spray cold water with the hose around the unit to get the unit to blow cold air. why is that? Is it because I have not clean the unit with soap like you showed on this video? Thanks

The more expensive filters do help to filter more allergens in the air especially for families with allergies. We have a lot of year around allergens in south Texas. I guess its a give and take, but I prefer a better air filter, its personal preference, but I do also see your point on air flow.

GOD BLESS YOU . . ! My systems working now 😭

Thanks a lot man !!! The AC is working

Your mention that hot air is supposed to come out from the top, what if that's not happening and just cool air is coming out?

My power company put locks on my disconnection box next to the HVAC unit, should I cut it to disconnect or would the circuit breaker be good enought?

Thank you sir that work for me 👍

My Ac not working checking outside and the fan is blowing out cool air outside from the top of the unit does any body have any ideas

Where can I buy a new capacitor? I can't find any stores that sell them or have them in stock. How much will it cost to just have an AC repairman come out and replace it?

You should tell people to discharge their c capacitor

Thanks! Will be on my way to Home Depot tomorrow morning!

I've had an issue a couple of times with the drain line being clogged so I went out bought a Shop-Vac to unclog the line that didn't work try to jump-start the unit by spinning the blade that didn't work turns out the breaker was tripped

Thanks man

Excellent video

What if everything's running inside and out but still no cold air? Lines aren't frosted over.

Hi, do I need to only have unit off when cleaning or do I have to shut it off with fusebox, thank u

"For techs only." Nudge, nudge, wink, wink. Say no more, say no more!

Big kiss Bro, you just saved me 😆😆😆

I need to clean my outside coils, l bought a screen cover on amazon pretty cheap, looks like a bug screen, and zips up, that will keep it cleaner. 👍

Yeah no, I've paid 2 different techs that both charged me $79 to diagnose the issue and they both couldn't figure it out. They both suggested I just replace a 12yr old unit with a new one. At a cost over over 5k. My issue: One day my ac went out, after trouble shooting, found out that the thermostat wires on my roof top a/c were so sun dried that they hade exposed wires and clearly took out my transformer (volt test showed I had 120 but no 24v. So I ran new thermostat wires and waited for my new transformer. 6 days later I installed and boom. Got 24volts and both the blower and compressor kicked on. Got off the roof went inside just to find out it's blowing hot air. Couldn't see any mixed wiring, so I thought it needed a charge. First guy came and told me that mechanically everything is fine. It has plenty of Freon and the pressure gauges don't seem to show any leaks. But he couldn't figure out what the issue was. So I called another company and they said the same thing, they tested the hi and low side and said everything there was fine. But couldn't figure out why the coils weren't getting cold. So now I'm stuck with having to pay 5k for a new unit after already investing $150 in new parts. Blah. Thanks for reading my rant.

No cold air here, so I took a look at my capacitor and it doesn't seem like it's about to pop, it actually looks brand new but it's not, it's the original capacitor from 11 years ago when I bought the rooftop unit new, then. Replaced the inside filter is new and the surrounding coils are clean. I tried the stick test like you did, but it wouldn't catch on unlike yours that needed just a nudge. I have a capacitor on order, so I'll replace it when it arrives. If it's not the capacitor, what else should I check. The unit turns on and I have the Fan setting on On instead of Auto on the thermostat. It does make a noise and the vents are blowing air just not cold. What am I missing?

What store do you get capacitors at?

When an ac is bust. Amana= aw man

great video

Thank you, mine started running after first 2 steps. Crossing my fingers that it remains functioning.

awesome!

I am a HVAC tech I've been doing this for 23 years there is a reason why your run capacitor is going bad it's either the condenser fan motor itself is going bad or the compressor could be going bad it's pulling too many amps and killing the run capacitor you need to call your local HVAC tech

mine is the fan runs but no cool air. Tech came out cleaned out the unit, refill Freon and said to monitor for few days. after two days, we are back to hot air blowing again.

My ac cools only at night when its cool outside, in the day time its not keeping up with set 75 on thermostat, also liquid line is sweating also only when it cool outside, does anyone has any ideas? 8 did clean out evaporator with fan and condenser coils, new filter, new cap. Please let me know.

Thank you for this video!

I noticed he did NOT discharge the capacitor by putting screwdriver across terminals. This can give a serious shock to a newbie. Be careful discharge the capacitor before touching it.

How to fix when your line breaks on your AC

So is that the over all maintenance of an AC unit..

I just grnd capacitor and then you dont need gloves,lol

Can u get those cheap filters at home depot or lowes?

Funny, are those Linemen s gloves or do you pour a lot of concrete :) You pulled the disconnect you don't need em.

Sooo I can't get the fan to jump start the unit

Cheap filters. ✔

hem to common & fan to common

Unfortunately cant see any wire switching, Thanks anyway

Do you think the sunglasses in the house make you seem more intelligent?

How do I find out which capacitor fits my unit? It’s an old unit that was here when I purchased the house.

I’m sooo fuckin hooooot !!! 😭😭

Wish me luck

Something weird happened with your eye; might want to get that checked.

The expensive filters are not primarily a marketing ploy or rip off. The higher the MERV rating the cleaner the air. Did you know a MERV 13 or greater will captuure Covid 19 germs and keep them from recirculating throughout a building. Here is the issue under normal conditions. If you don't have enough air flow as happens often because return lines aren't sized properly you choke off air flow and can burn out fan motors and not get enough cfm's at the registers. So making a blanket statement that they're rip off is moronic

What or where is the capacitore? 😂

herm

I didn't follow what you did. You are hiding most steps.

Your good name?
