Whynter ARC-14SH Air Conditioner - Maintenance 

Just got a 14S and it works amazingly well. Got tired of the landlord putting crap ACs in here that last a year or 2. So I invested in a good portable.

Year two for my unit. Just pulled it out and decided to re-watch this video to be sure we are taking care of my summer BFF ; )

Don't blow the dust IN to the coils. Vacuum it out gently, taking care not to bend the fins. You can use a brush attachment on your vacuum hose, and brush WITH the fins, not across them. If it's still dirty, you can get a can of coil cleaner and use a soft bristle brush, again working vertically with the fins, not across them.

I bought one of those 2 years ago. That thing is a monster. Works great! I definitely recommend it. 👌

We’ve had ours 11 years and still performs well.

Thanks for the video. I agree these are great units. I have had mine running for over 4 years now.

I was specifically looking on how to get to the coil that is visible through the hose connections. When i take the front cover off its still unreachable in the back. But I did enjoy the video. I think I'm going to get up can of that no rinse coil cleaner and just spray it from the hose connections mine has also been a great air conditioner although recently it is not as efficient as it used to be due to so much dust on both coils

Thank you, friend. This video saved the day at my office.

Thank you and I now know how to remove the hoses. I was using a screwdriver and pushing the tab in and I was afraid to break it. I read somewhere to turn the hose but I could not figure it out. Great job and thank you .

Thank you again and we will continue to watch your videos and we have seen most of them and they are very helpful. Thank you again.

I would use a vacuum to get the dirt off the coil. Air pressure might just blow some dirt inwards.

There is also a condenser inside the rear of the unit. Have you cleaned that?

Funny it was made to years ago but still helpful today. Love it.

Thank you for your instructions! any reason why mine smells funny? kind of sour smelling... please help! only had mine for about a year.

i like that youre making videos to help ppl out but wiping a machine isnt maintenance lol and you shouldnt use a air dust blower on the air vent as it is blowing the dust further in.you could use a small brush with a vacuum to get all the dust out. Here are my tips for those with this unit: get a washable air filter and a carbon activated air filter. cut them both to size and put it on the filter frame . you can also put them on the air intake tubing(the one that brings air from the outside). if you put it on the intake tube, MAKE SURE you make a grill piece out of aluminum mesh so the filter doesnt go in the unit as it could cause damage. if you have to drain the unit daily, it's bc humidity is high. when it rains and when its really cold i disconnect the air intake tube(that brings air from the outside) and cover the tube(not the machine) with a thick towel so theres no cold air coming in from the outside. when doing this, the unit isnt bringing cold/humid air in and doesnt require to be drained daily, also the unit works less to heat up a room. the heater on this isnt all too great when its 40 degrees out. the bad side is that it isnt bringing fresh air in but i only do this when its really cold and/or rainy. to drain mine: i also have a rubber hose connected to the drain plug that has a valve on the end. i just have to open the valve and drain it onto a pan. when it rains my unit can hold alot of water and unit stops working until i drain it. i've had mine for a few years as well and my air grill looks new and machine works great. here are some links of the filters i mentioned. www.amazon.com/Holmes-Carbon-Filters-HAPF60-Filter/dp/B000063SKE/ref=sr_1_14?ie=UTF8&qid=1540068885&sr=8-14&keywords=carbon+filter www.amazon.com/Duck-Replacement-Conditioner-24-Inch-1285234/dp/B002GKC2US/ref=sr_1_30?ie=UTF8&qid=1540069164&sr=8-30&keywords=washable+air+filter

Is there a good way to remove the front vent cover to clean the fan wheel? It's spitting out dirt and I can't get thru the little slats and grid on the output vent. Any help would be appreciated..

I'm seriously considering getting the ARC-14S model. Hate to nit pick, as I know you're trying to help show how to clean them, but I would never push the dust farther into the unit by blowing it with canned air. It's far better to vacuum it out.

Can I install a drip line that will constantly flow into a drain? (for server room using Drop ceiling plenum for exhaust air) The room shares a common wall with the kitchen, I'd rather drain constantly as opposed to having to drain.

How did you get your hoses and hose fittings off? I am a little afraid to take them off and break something.

Our unit is only 2 years old, and we have now an issue with the dehumidifying mode. filters are clean and new! The unit is running but no water is coming out from the drain? Any suggestions? Thanks.

I got my air conditioner last year and it worked wonderful and I've done all the cleaning already it's not cooling as much this year and The red light indicator never worked and it never shut off when it's full of water I don't know why it's not cooling as well

My plug melted near the prong and is running very hot, I don't feel safe having the unit plugged in. I was running it through a heavy duty power chord, and I suspect either the power chord or the unit power chord is the culprit (not the wall socket). Its looking like the best thing to do is replace the plug, but I'm having difficulty finding information on how to do that. Do you know where I should start? A repair service seems out of the question.

How do you take it apart to clean inside machine. Looks like mold or dust on blades down inside machine

Is it possible to recharge the refrigerant on the unit?

Hello! I recently had this problem where the compressor won't stop running even after turned off, neither does the surrounding temperature matching the setted temperature. I turned it off by pressing the reset button and have turned it on and off a few mroe times to make sure the problem was replicable and once I confirmed it was I never turned it on again. the manual suggests not turning it on and off solely by using test and reset. Do you have any suggestions?

Thank you for this!! 🙌🏾🙏🏾

Zhank you for zthe video!

I bought one & it makes a rumbling noise what do I do. I don't know if it is supposed to do that or what

Do you have a video where is shows what screws need to be removed to get inside. I need to replace the evaporator fan?

I have the same unit and my unit keeps getting full of water and shuts off. I constantly have to drain it every 2 hours to work. Any solution?

Can I unplug the condensation stopper and just put a permanent drainage hose on it that extends out the window with the other hoses?

Can we keep it on car backseat and transport it horizontally does that cause any damage ?

How expensive is this to run? How much does your electric bill increase? Thanks

Hey my unit has a weird issue. Sometimes when I turn it off, the condenser turns off but the fan remains on and nothing I do will turn it off short of unplugging it. Sometimes it'll randomly shut off on its own after hours. Any idea what's going on?

Hello, mine is having also the heating unit. But it produces very little heat. Any help?

I’ve been using it for 2 years and it stopped cooling :(. I’ve always done the steps mentioned here too

Hi ,is the intake hose optional?

Just bought one 🤫 wooopwooop

My ac keeps filling with water within hours It ran well for a month and now is filling with water fast

How do you remove the hose connectors? I can't seem to get them off of mine.

How do you set up the timer??

I'm having a flashing red light does anyone know what this means?

Yikes, the condenser is dirty. You'll get even better cooling if it's clean.

Are you seriously blowing that dirt straight into your kitchen?

I unboxed my air conditioner and there was oil everywhere. I let it run for an hour. There's a smell starting. I turned it off.

Where the water go

After the first year of my 12000 btu Whynter, it's not cooling at all. Sometimes it sounds like the compressor kicks on, but it definitely isn't cooling. Do not recommend this unit as I only got one year out of a 500 dollar A/C unit.

Thank you for the video. Why didn’t you vacuum out the dust behind the machine? Next time please close your kitchen drawers before you do a video its very distracting.

because mine doesn't cool as much as before

OMG that's not how you clean it....
