You are the only person that explicitly showed which way the arrow points. Thank u.

I live in an apt complex where maintenance changes the filters every so often. I fell asleep I guess and missed them knocking on the scheduled day and had the chain on my door. When I called, they said I'd have to do it myself (I guess they were a bit miffed). Well, OK, I've been changing a/c filters for close to 40 years by myself. I could not for the life of me figure out where to put the damn thing!!! Looked up the model number and came here to KZfaq and here's Dustin!! (my son's name by the way) and I saw the tray slide out at the bottom and BINGO! Got it in all my lil ole' 70 yr old self :-) arrows up (cuz that's how the old one was) for the air flow and everything - even dated. I'm so proud! So, thank you Mr. Dustin for your help in posting this for us simple folk. Bless you! ((hug))

Thank you for reminding us about the arrow, adding date the filter was placed and just all the helpful tips! You literally are the only video explaining the arrow and chicken wire on my 3 M filter! Thank you again!!!!

Wao! Thank you very much for all the consulting, it helped me a lot to understand the whole process behind in terms of good maintenance for a couple of dollars versus a great $$$ repair result.

Loud and clear Sr.Very informative.Thank you very much

Thank you for your help with the AC unit greatly appreciated

Great info! Thank you for sharing!

This was a great reminder to change my air filter, thanks!

Very helpful to me today! Thank you!

No need to call service company to come and defrost the coil. Remove the cover, and if you see the coil is iced over, keep system off except maybe the fan and let coil thaw. It may take awhile depending on how bad it is iced. After completely thawing, put in a new filter and then let her rip.

Thank u!

Nice video, thanks for sharing.

Wow I been at my home for 2 years and didn't know I was supposed to change it. It's a lot I'm learning.

I forgot which way to put the arrow so I am here thank you 😂

Go to the point,.

wow! please start the demo!!!!!

Perfecto great help

My furnace came with a reusable/washable filter. After a few years I decided I wanted better filtration and bought some new filters. They are EXACTLY the same size as the old filter. However, when I put one in, it is a very loose fit where as the old one was a tight fit. I left the new one in for a bit but it was sucked up partially into the furnace. What is the problem??

This was so helpful!!! But I'm still confused on which way to face the filter. The air is sucking upwards. So does that mean the coils should be facing up or down? Right now I have the coils facing upwards and the arrow is pointing up. I just want to make sure that's the right way.

Florida power and light just came out to do an energy assessment for me. They said I needed a larger AC return box because it was too small for the size of my air conditioning unit. So I'm going to retrofit that to make it fit the unit but currently my AC filter is on the wall return grille. When I put a new box on he told me to put the AC filter just under the coils and air handler. Is that the best place for the filter? I also heard that the best place for the filter is where I have it located right now on the wall in the grill and I just want to make sure that I'm not doing that wrong. Tyia

We just moved into a new home and we have 2 ac units upstairs in a hallway closet similar to that one. It’s the same AC with the filter box at the bottom, but on that same wall, below the closet door, there are 2 large vents. My husband opened them up and it was full of dust. Should I have a filter on those vents as well?

Hi Dustin. I change my filter every month. Last week, I noticed the back corner of the old filter was slightly wet, now the new one is a little more wet?

what about the big filters on the door before the handler? the coil mesh filters or something...? if i have a filter on the grate door. is there one in my unit as well? miller unit, the return is right at the unit

Thank you this is the closest I have found on a model close to my air conditioning unit. Do you have any videos cleaning the fan blades as mine probably does need to be clean. We have lived here a few years and the owners never cleaned it nor did they do any upkeep.

If the filter is inserted flat (horizontal), should you always place it with the arrow facing up? Thanks!

Hello. Thank you for this video it was very helpful. Is it okay to put the filter in the upper level or is it better to put it in the button level?

Hi. So we have 2 slots (top and bottom). Can we use 2 filters? Thank you so much for the video.

Carrier AC units should come with a tray to hold this filter rather than it just flopping around in it. They could engineer it so that it takes a standard size. but i wouldn't want to break the geniuses hearts. They are way too smart for me. Good Video though!

Our box under the furnace uses a 16x25 filter. The issue we have is the return is very loud and we have to take the grill off to vacuum the box. Would having the filter outside of the air return vs under the furnace reduce noise?

What if I don't have a a/c filter cover door? Will that affect the performance?

Sorry to bother you sir got another question 🙄. My air handler is in a closet like in your video. And I was wondering how big the opening should be under the unit. The filter is on the door. The opening for the return seems a bit small. Wish i could send ya a pic. Since we moved in i notice my ac turns on every 10 to 15 min during the day and about every 30 to 40 min at night. I understand it's alot hotter during the day especially with Temps from 95-100 her in south texas. It's starting to cool off here, yet I feel the ac is working more.

Any ideas why the air handler runs and also blows cold air in the upstairs zone every time the AC is on downstairs in the downstairs Zone. I have the thermostat off upstairs. Thanks

You’re from Florida ? Must be way different operating than Winnipeg. We change filters quarterly here on our rooftop air handlers and even in suite filters are only once a year since we run a/c only for the summer months

the handler is in my garage and has a filter box like your video. i also have a return on a wall in my living room that has a filter. do i need to use both filters? my hvac guy said only use the filter box on the handler. leave the filter off on the one in the house

My 3m filter has the arrow up on the opposite side of the chicken wire. So which way do I install it?

What other size filter can i use if my ac is 17x19x1? I cant find that size anywhere.

So the air comes thru a vent before it and thru the machine while the good air comes from vents on the ceilings?

Need Help ! My air handling unit has a BAR right in the middle of the filter. It makes it impossible to remove. Is there a Trick to get the old filter out ? I've never seen a bar like this. It's a 1991 American Standard unit. Looks very much like the one in your video.

Ive been putting my air filter in wrong for soooooo many months . I even saw my maintenance man put it in which is the wrong direction now that i see this video smh

Question. Can you blow these filters with light compressor air

Hello my carrier HVAC unit pulls my air filter up when they system comes on does that mean my filter arrow should be pointing upward? I just purchased a new home and the filter that was initially installed didn't have an arrow on it to tell me which direction the air filter should go

@ 2:18 you said there is two levels is it okay to use either level I have a metal washable filter Id like to use but it only fits at the top level.

Is it intentional if a year ago an ac repairman forgot to replace the air filter and our coil and motor died because it was filthy?

Is this filter different from the filters in the wall ?

Thanks. Question why does water leak in the pan ?

I just cleaned my coils and replaced my filters today. A few hours later my closet is soaked and the filter was sucked up.

Your vid is still helping haha. Where can I get a filter box like yours? A/C tech wants to charge me 250.00 to install one. Wondering If i can do it myself. 250 isn't bad though, but just wondering...

how often should the filters for the air vents be changed, also monthly?

I have a digital thermostat that the back ground is looking black and continuing to fill the screen. What is it and how do I clear it?

So if my filter has the arrow pointing up on the coil side, I put the coil side up?

Do you put in 1 filter in each tray?

My furnace is missing a filter, so I don’t know what size I should get. How can I measure that?

What do I do if my filter is 20x23x1 it is absolutely expensive 😢. Can you help me a way to remember which way it goes? I see an arrow up and/or down? Which way is the correct way to put it?

and where do you find $3.00 filters?

Home Depot is the cheapest I have found for air filters.

Counterintuitively, a dirty filter makes the blower motor use less current. Just saying, keep your filters changed! But don't use those darn HEPA filters, they can stop up in a week or 2!

My friend told me to change when I get new electric bill

I just moved in to my house and the door were the ac is in has a filter and then there is a filter under the unit that has a metal edge. Is that metal filter just a factor filter? Never seen a metal edge like that. The builder who sucks, never explained anythihg.

I had a block of ice fall on the filter. Whatchu think about that!? lol

Who leaves their AC running during long periods away from home lol
