What to do when air conditioner freezes up: Air conditioner tips for summer

In this video we share what to do when air conditioner freezes up.
One of our air conditioner tips for summer is knowing what to do when you have a frozen evaporator coil, or a frozen air conditioner. A frozen air conditioner is a common air conditioner problem and you can help yourself by first turning everything off. You need to get the ice off the coil in order to fix the problem with your air conditioner. If your air conditioner is not blowing cold air, it could be a frozen coil so after you confirm that your coil is frozen and you turn everything off, you should change your furnace air filter. Air flow is a common air conditioner problem and could cause your air conditioner to freeze. You should also have a professional air conditioner tune up to check to make sure you have a proper refrigerant charge. You should also check to make sure something is not stuck on.
These air conditioner tips for summer will help you save on an air conditioner repair and know what to do when air conditioner freezes up. If you keep a clean air filter and maintain a proper refrigerant change to your air conditioner. We also explain more about why does your air conditioner freeze up and more helpful air conditioner information for homeowners from One Hour Heating and Air Conditioning.

Thanks for watching! Have you ever had ice on your coil? Keeping your filter clean will help greatly!

[@mytube3687]

I have similar problem .Thanks for nice video, I have a Panasonic split ac withR22, when I switch on and set temperature to example 24 c the unit keeps works below 24 c continuesly ( compressor on). When I switch off and leave the unit on standby mode the indoor unit freeze ( making ice).what could be a problem?

[@Pivot-99]

I had a situation in my last apartment where everyone shut all the vents except myself. Obviously two days later the system was completely frozen in a solid block of ice. Well now I’ve been in a new apartment for two weeks and every vent is open. I noticed the system was no longer blowing any air because it was starting to freeze over. We have managed to keep the system feom freezing but it is not blowing cool air. What kind of symptom is this?

[@matthewmoody277]

When youre right your right! My coil is a block of ice like you wouldnt believe!

[@pornstarlivesmatter3319]

ARE YOU GUYS IN OHIO....LOL

[@marleyaxton123]

I guess Im randomly asking but does any of you know of a tool to log back into an instagram account..? I was stupid lost the login password. I would appreciate any tricks you can offer me

[@chachita176]

I love the father-daughter discussion format. Their dynamic was not only super helpful but calming during a very stressful moment when I needed it the most and as I know nothing about HVAC - admittedly just a homeowner with no expertise in this area. Being a weekend evening, it’s not like I can call a HVAC company and especially as we’ve had a heatwave week they’re likely to be booked anyway. And of course there’s always the worry of repair cost. Andrea broke it down for us by asking the clarifying questions that she knows would aid typical customers. And I appreciated that both Ramon and Andrea pointed out junctures where one can pause and see if the suggestions would negate the actual need for a pro. In my case, I finally noticed by evening that my downstairs level was really struggling all day to be cooled. I went to the finished basement (where the AC/furnace unit is) and to my horror finding parts of the carpet soaked. Then my eyes followed the symptom to a partially frozen pipe. Thereafter, when I tried to take out the old air filter, I found that it had somehow become disfigured. Couldn’t understand why at first but it’s likely that it initially got dirty and caused the problem itself. Then the AC freezing/melting began and the trickling water got the filter frame wet, resulting in the changed shape, causing a slight jam. I’m currently at the phase of running the fan only overnight. After implementing the first couple of steps mentioned before it, the coils are already thawing at this moment. I have to wait for the thawing and flooding of the basement floor to cease. I hope I’m back to normal tomorrow AC-wise! The carpet can be dried later. Pls keep fingers crossed for me! Thank you so much for putting out this video!

[@TheAirOfAuthority]

Wow thank you so much for the amazing compliment! I am so happy we were able to help and I hope everything is working well for you today.

[@AliMahmoudjr]

Did it end up fixing itself?

[@reneewilliams554]

Hello, I'd like to know too. I am having the same problem with my outside unit.

[@chadrob8384]

This is exactly my issue. The ac condenser is running, the blower is running and no air flow through the vents. I figured out myself that it was more than likely a frozen A coil. I then surmised that I should turn off the ac but run the blower to thaw out the coil. Then I came across this video and it could have saved me three hours of trouble shooting after working a 14hr day. Great content, wish me luck with letting this work and God bless.

[@johnwibbels4678]

I love how us as humans can communicate. The idea all we are talking about is a air conditioner system. We need to communicate with each other in a way of helping each other. Good and honest care and concern nice video

[@nxdita]

I turned the thermostat to 80 and then turned the fan on and within 2 10 minutes the block of ice started to thaw and the ac was cooling! Thank you so much for your help!!

[@maduenodiego]

👍

[@tahomalewis2300]

A friend sent me to your page, and I did exactly what you said and now the house is cooling down! Thanks for making this video 😊

[@TheAirOfAuthority]

Great! I’m so glad it helped!

[@NIYA-7]

Didn’t work for us. 😔

[@kevinbright3080]

North Carolina split system. Iced up evaporator (inside A coil). Not a filter issue. Not a refrigerant issue. Was told my condenser(outside unit with fan on top) was a 3 ton system and didnt have proper ventilation inside at the A coil.

[@bballerforever]

This all makes sense and corresponds with my conclusions as a non-HVAC expert. I had two HVAC guys come out already and NEITHER checked or even mentioned the evap coil! Instead they said the Nest thermostat needed to be rewired, which did absolutely nothing to improve the situation. Thank you!

[@Wemakemoney305]

I had the same issue! They said my second new Nest is the issue

[@sniffles8655]

Sounds familiar. That is why I spent a long time learning how to do it all myself. You have to have a license to buy Freon/refrigerants, boards, motors, and all, but you can order it all online without one. 😁

[@1Classylee]

Wow!!!😮😮 I live in an apartment and this is a new unit!! The filter is even iced up. I am waiting for the thaw!!! Thank you for a well informative video!!!

[@someguyfrommemphis]

Great video. Minor ice here. Blower on, system off. Going to melt the ice and put in a new filter (we're overdue)! Thanks for the tips!! 🤞

[@TheAirOfAuthority]

Glad it helped!

[@carreon1081]

How to turn on the blower

[@dekelsey1]

This is the best video I have seen on this topic. I suspect I have installed too dense of filter, anti-allergen. That's the only thing I changed and I can't get really cold air out of the system and it blows weakly now.

[@ysaysa]

I’m struggling with this now. I went from a perfectly cool home (69) and changed the filter to MERV 11 allergen reducer and the next day my home wont go below 76. I removed the filter and turned off my system. Hoping this will resolve it. Ugh.

[@brentkevern]

This was really good and something I've bumped into before. Given all the vendors our family works with over time, easily you all are the best. Super professional, always on time, always get the problems resolved in a friendly manner.

[@TheAirOfAuthority]

Thanks Brent, that's so nice of you to say! We appreciate your business and glad we could help!

[@SpiritSeekerSquad]

Its September 1, 2024, in the middle of Indiana. Our house was 79° when we noticed its hot in here! We usually keep it 74°. So, I checked our filter and yeah, it was past due for a change! Luckily, we had just bought one recently! The new filter is in. The blower is on. And we wait! 🤞🏼🙏🏼🤞🏼 Edited to add... its also 80° outside.

[@GC-213]

Try 87! That's what I'm dealing with now! 79 I WISH😅.. hopefully this video helped you!

[@saifhussainmohammed7054]

Really helpful, I searched ice found in AC and I was directed to this video. 😇😇

[@EldonHuff]

Very helpful! My filter was very clogged and I'm letting the blower run now to unthaw. Fingers crossed this get it fixed!

[@Sistagirl305]

Thank you so much for this video. Followed your instruction to a tee and unit working just fine now.

[@inversionproduction]

Thank you, thank you,thank you, My daughter thought she heard water inside where the filter is (yes it was dirty) did what you said, put the fan on and you can hear the water come out the back flow and I can feel the air blowing stronger as it thaws.Thanks so much!!🙏🏾

[@TheAirOfAuthority]

You are so welcome! I'm happy to help!

[@transporter6254]

Exactly! Right here in our bedroom, right now at 10: 00 pm bruh I need this tips thank you

[@vc9607]

Thank you sooo much for your expertise it helped us greatly 😊 we won’t forget to change the filter again!!

[@minhtrinh2524]

Many thanks SIR for providing good tips to take care frozen AC issues. I'll try it.

[@mikeyc4525]

I love your video. I'm having these issues. I keep having water leaking from the ceiling, where now I know from your video, what the problem is. The landlord has had the AC people out here at least 3 times to address issues with the system, but it still freezes up. I'm 70 years old and my roommate is 74 years old. I have copd and my roommate has heart issues. Yesterday here in Oklahoma it was 107 heat index. I don't understand why these AC guys can't fix the problem? Your information was helpful.

[@mhill2468]

So glad I watched this one! Best video of everything that’s out there I’ve seen so far

[@brendacardenas1420]

Omg September 22/22 My ac unit gave that problem check my air filter I vacum the grill it had Lira if dust put new filter resolved the problem thank you so much your Hispanic follower!!

[@kennethdandurand3472]

Succinct, except maybe turning on the heater to make it melt faster. One of the better videos I have seen.

[@rbljackson]

Yep...explained my situation exactly. Troubleshot. AC wasnt cooling but running, noticed poor airflow at the vents. Pulled the A Coil Cover and its a block of ice. Filter wasnt too dirty, but we will put a new one in and see what happens after the thaw.

[@slowjamcdub]

How did it go?

[@GoodVibeTribe]

You two are awesome! Thanks so much for the practical step by step in plain English.

[@TheAirOfAuthority]

Happy to help!

[@21CryBaby]

Purchased for my RV best investment this year, noise level not bad it's in my bedroom window, my mounted tv is above it I have no problem enjoying a movie while it is on.

[@lynntunes]

THANK YOU! I’ll check all these things!!!

[@KMHrock89]

Thank you so much. Our air went out on literally the 4th of July once so my family knew we were hurting, got that problem fixed. Our air quit working again today (thank goodness in spring not the heat of summer) so we feared the worst but saw that the coils were frozen. I think my problem is dirty air filter (it’s a weird Jerry-rigged situation, I’m probably going to build a box for a legit air filter over the return) but we may have a tech come check our Freon level just in case. Very educational video, thanks again. Liked!

[@kadel05]

My house is a furnace right now and putting your methods to the rest wish me luck!

[@jstevens74]

Thank you! Clean filter but must be the wrong one, air flow issue. I removed it and it's fixed. Thanks so much, again!

[@hadassahjoseph9877]

Thank you for getting straight to the point

[@EricPardo]

Thanks from Bethesda, MD!

[@TheProphet-gc1pt]

Thank you guyss sooo much. I'm sure I'm low on R22. It's discontinued so it's very expensive so I'll have to buy a brand new Unit. Eventually. So I may get a pound of refrigerant to cool the house for a while until i can get a new unit. But My air filter was stuck in the vent. So I'm gonna free that as well. Once the ice cools i think i will get some air flow but this video was a God send thanks you so much you and your daughter.

[@andrewsheehan1124]

Excellent video and summary of actions for a A/C freezing up.

[@theForrestGalantey]

Best people and advice. You guys saved me tons, thank you!

[@TheAirOfAuthority]

Happy to help!

[@eloygarcia8723]

Awesome thank you folks!

[@inix9748]

Great video!! I noticed some ice in the coils, not a large portion. Checked the filter, it was fine. So, maybe the issue is the refrigerant level. Time to call a technician?

[@peaplecreative]

Great video, straight to it and easy to understand. Thank you for doing this. 👍

[@vinnyv5717]

Thank you great advice. Vince

[@Genob69]

It was a dirty filter in my case. Thank so much you!!! 🙏

[@smoton2]

My filters are in need of changing I came home last night and it was hot in the house. Not sure if it was ice, but the air is back on. So I'll be changing the filters.

[@jshel4892]

Outstanding! The info you provided was on point. I did everything that you both mentioned, and my AC responded in kind..It took about 2 hours to get my AC back in running order....Thanks again 🙃 we slept well 😴 😇🤑🫡

[@glennsmith6380]

Do you also turn the outside condenser off or leave on

[@mikesalles]

This video helped me solve a problem, thank you so much!

[@TheAirOfAuthority]

Glad it helped!

[@michaelboutililer4880]

Very helpful and informative. Thank you

[@stevealaska73]

Thank you for this. I have a scenario where a few of the coils about in the middle are frozen. The air from the registers is blowing strong and cool but the temp of the house just won't come down from 80 degrees. I think the drain line was clogged earlier today and so I flushed it with the hose. I turned the system off for a few hours and then tonight I have the same frozen coils in the middle symptoms. Any idea? Oh and filters are clean.

[@CindyAsselstine]

Thank you for the help!

[@ConOp-Experiment.]

Thank you so much!!!!❤

[@teddlemmon2599]

Thanks very helpful 👍

[@cromanxx1]

Very helpful and informative discussion.

[@Gumbo72203]

For window units, if we turn it to FAN and put the speed on high, will that blow air through the frozen coil the same way you mention the blower here for an HVAC system?

[@azildaneil8156]

Thank you so much God bless you

[@manuelsantos8213]

Great video and easy to understand , thank you

[@TheAirOfAuthority]

Glad it helped!

[@Sean-Aviation]

excellent video! What can cause an AC to run low on refrigerant? is it normal overtime to fill it up?

[@lunabee9606]

Very helpful!! Thank you🥰🥰🥰

[@transporter6254]

This one was nice! Our aircon metal filter freezes so I hope this tips will work

[@jamesoliver5688]

What about putting a fan on the block of ice and dispence the humidity til we can get a dehumidifier ?

[@manuelfelipejr2723]

It help so much for me.more vedio tips..thanks a lot ..God bless you...

[@benfix]

This was a great video. Wish everything I researched was like this.

[@qmerk2661]

thanks guys! very helpful

[@TheAirOfAuthority]

No problem!

[@kevinbright3080]

To correct this problem I closed off the vents on the front panel of the evaporator unit. Went to the wall above the evaporator unit and cut a 20 x20 access and installed a vent to get more air flow to the top of the evaporator unit. Still was getting iced evaporator. The solution was I removed the insulation from the interior wall of the evaporator A coil area which caused excessive condensation onto the Evaporator coils causing ice issues. I had to cut 2 pieces of cardboard 16 x 20 and put one on each side of the A coil. Gues what. No more condesation and no more frozen A coil.

[@ideal9814]

Thanks for the tips!!!

[@chizo5097]

Can a missing piston be a reason of a frozen coils.?

[@DetroitHomeInspector]

Great video. Can I use your video on how to train home inspectors on this issue?

[@moneyaintathing817]

What about if a furnace has no filter?

[@cbdouglas1]

Can you use a blow dryer to thaw the ice quicker?

[@wlt16]

i Turned my AC off and turned the heat on and thawed it out in 20 minutes

[@toddsadler4199]

Fabulous help. Thank you.

[@malkavian5]

I have some freezing, noticed all the vents to each room were closed. Could this have caused icing ?

[@Hey_you_guys]

No expert here but I would think all the vents would cause a restriction in the system that would be the equivalent of a plug filter so I believe the answer is yes.

[@4sho910]

Thank you guys

[@Mriluigi]

Would a weak air handler fan capacitor causes the fan to stop running which will built up ice on the coil?

[@TheAirOfAuthority]

Great question! We answer it in this week's video: kzbin.info/www/bejne/favcdJ2Vg8SZpaM. We answer your question around the 1:25 mark.

[@desertwalker240]

A hairdryer also speeds up the de-icing process.

This video was so incredibly helpful I can't even thank you enough

[@joecalabrese8979]

Had an AC guy come out to do a standard check of system after a year. He put thermostat at 62 to kick the system on to run the test. He didn’t put temperature back to the temp we had it at (70). Because of that our AC was trying to hit 62 for almost two days without us noticing because we have the fan always running. Low and behold it was now not reaching our desired temp. Our coils froze. So I turned my system off and now there’s a bunch of water coming out from our what appears to be above the furnace. What do I do?

[@sarbaz-q4f]

My air conditioner is Danby 24000. I checked the two rear valves and checked the filter. There was no problem, but the air is still hot. What is the reason?

[@rmg1035]

how much does it cost ot clean my evaporator coils in my air handler?

[@mariahp.6993]

Thank you!

[@frankmontez6853]

Going to someone's houise to see why her inside unit froze up . I told her i would try to help even though I'm not a tech just learned a few things with fixing my system . One thing you forgot is the clogged drain line . A lil bleach to clean it as my AC tech did once when mine was clogged up and evap coil was frozen

[@aaronlive15]

Great info!! Thanks

[@spiritcreek9813]

Thank you great video.

[@MeandMyself-r3i]

Thank you

[@guitinwidit]

I had a power outage and when it came back on after about a half hour it seems like my AC hasn't worked right since. I have a Honeywell programmable thermostat that I never really bothered to learn - shame on me - so I fiddled around with it, thinking something wasn't right in there. Ended up taking the face off and replacing the little disc 2032 battery while in there since I know it's a least 4 years old. Two days later I still have the same issue: outside unit running but nothing coming out of the vents inside. Is there some kind of secret reset on the thermostat, like holding two buttons down at once? I had also turned the unit off at both the thermostat and the breaker and waited 30 minutes. Maybe that wasn't long enough if there was a lot of ice? I just think the problem I'm dealing with is related to the power outage, but we've had plenty of outages before (I'm in Florida) and it has always come back on. Any ideas? Is there something in the programming of the thermostat that got "flipped" and needs a reset but since I didn't do it the condenser is now iced up? Thanks for your help!

[@guitinwidit]

Follow up: It ended up being the fan motor up in the attic condenser unit. Thanks

[@JoelMMartinez777]
