- After working in a hot garage, I decided to try out the Hessaire evap Cooler. This is a 500 sq. ft. coverage unit and my garage is 400 sq ft. So let's see if this works.

I have the same one and my dogs love it. I have it pointed at the entrance to my dog house and it makes all four small dogs to go inside the house and sleep like babies… and they seem very comfortable and happy… it’s 107 here in Texas.
Now that’s a great use of the unit ! Great story. Thanks for sharing.
"My neighbors are gone so I ran it over to their power supply" i gotta good laugh out of that 😂
Thanks Mikel ! 😁. Thanks for watching too.
I love it, Thank you. I do woodworking in my garage in Scottsdale, This is exactly i need it to give some humidity to my material as well as cool the place a bit.
You are welcome Reymondo. Check out my most recent video on replacing the pump. They seem to last only a year or two. But they’re easy to replace.

Now that's what I call informative: - PHX, AZ, (check) 400 Sq Ft garage (check) and same make evap I was thinking of (check) although I see you bought the larger 1300 CFM model (I was thinking about the next model down)
Based on the result you are seeing, I'm not sure the next model down would supply enough temp change.
Thanks for the informative video.
Yea it’s about time to power it back up Steve. Getting warm again in Phoenix. Thanks for watching.
As others have mentioned, for best results, just crack the garage door open 3-4 inches only. In addition, crack the side door or window, if you have one in the garage. This will promote a flow through current which will help carry the hot air out. I place my larger evap cooler next to the side door which is about half way into the garage and I point it at the rear of the garage. This creates a current of cool air toward the back of the garage and forces that hot air back toward the front where it can escape out the top of the garage door.
All great tips that I’ll follow up on Drives & Details. Thanks. And thanks for watching.
Having the garage door open like you do, it would be difficult for any until to cool any room since heat is entering from 90% of the door opening. So if you are going to have the garage door open, I suggest installing a small portable wall under the door to the floor to block off air entering. Have two openings in the partition. One opening for the air intake to the cooler. The other to exhaust the air to the outside. However, if you have a window in the garage, use that as your exhaust and only have one opening in the partition. As it stands now, you’ll never bring down the temperature much since hot air is entering from the same door opening you are conditioning the air. Also, in order for evaporative AC to be effective , there needs to be an air change in the room or home every two minutes. So, assuming the following and keeping the math simple:
40O sqft area x 10’ ceiling= 4000 cuft
Air change every 2 minutes = 4000 cuft / 2 minutes = 2000 cfm cooling capacity.
As it now stands, the evaporative cooler should have at least a 2000 cfm blower capacity. I don’t think the unit you have comes close to that figure and is undersized. The method I provide here is the standard way of calculating evaporative air conditioning sizing. Some will use an air change every 2.5 minutes as opposed to the 2 minutes I used. If 2.5 minutes used, a 1600 cfm unit could be utilized. Even at this size, your unit is still too small.
A properly sized evaporative air conditioner should get the garage to around 80 degrees with a 10% humidity level and 110 F outdoor temp. But as the humidity level rises, evaporative air conditioners become less effective. Once you get into the 20-35% humidity ranges, the room temperature will rise and the air really muggy 85-92 degrees. And the air becomes very muggy.
It feels much cooler in an arid environment then the actual tempature drop, the moisture makes all the difference.
Great video, sir. I live in Vegas with a 400 sq. ft. garage so I might have to pick this up before May. As others have suggested, I still plan to have the garage door cracked about 6 inches and also have the side service door open as well.
Thanks ea0529. Yes, after trying different things, I did find cracking the garage door about 6” worked the best. I’m in Phoenix so our temps are similar. Thanks for watching.
I'm in Arizona too, GOlden VAlley. IT is May and is about 98 degrees outside. I got a big one cover 950 sqft and my temperature went down by 15 degrees within a couple of hours. I started at 3Pm garage was at 95, it is now 5:45 it's at 82. So that's quite a bit. I have closed all the windows except one to keep circulation going for dry and humid air. My machine is on low and same brand but just a bigger unit.
That’s great Theresa ! They do make a difference. I may have to get a bigger unit too now that I know they work. Thanks for watching.
Thanks for this review Jay!
You are welcome Tomatoboy !
I got one if these to run in my RV in cooler areas of Arizona, Utah, etc. I will stick one or two of those freezer packs in it to help chill the water if need be. After sunset, I can put them back in the freezer for use next day.
The ice packs sounds like a good idea cubey. I’ll have to try that. Thanks for watching.
He is a very naughty man 😂
HEY! You should open the door all the way....or better yet, put it in the front yard and cool all of Arizona! YAY, JAY! You're a thermodynamic JENIUS!
😂
hello sir
Can you tell me the size of the Hessaire Hose Adapter copper? The size of the threaded interface with the float valve, thank you
I am sure by now that you have experimented with the garage door. I find that 6 inches open at the bottom is best.
Right David. That’s what I did find out. I forgot to open the garage door once and geez, did it get humid in there ! Thanks for watching.
Same here.
Would you recommend two of these outside or a large one.I am hosting a graduation for my son and want to make a small area to beat the heat.
@@colecole3352 I would go for the one a size above this one, MC37.
@@JayVisnansky how much cooler did it get with 6 inchez?
@5:41 - the wall retains a lot of heat. Likely ~88F in the middle of the room. And because of the breeze created by the fan, the feel like temp is properly ~85F ( assuming humidity in the room < 30%).
I had that one and it did not work well, got the next size up and WOW what a difference.
That’s good to hear that it isn’t the make but the size. I may upgrade mine one of these years now that I know they do make a difference Michael. Thanks for watching.
Looking to get this unit for my 12’x20’ garage, you found that 6” gap at the garage door works best with the attic crawl space door open.
Thanks for sharing
I did find the 6” gap works just fine for the garage door opening Smokin’ Joe’s. But I do NOT have the attic crawl space door open. It’s closed with just the garage door open that 6”. My attic is hot, just like everyone’s, and I just blew in a lot of insulation up there and so I just keep it closed. But the evap seems to do ok when I’m in a 10 foot area of it. But here in the Southwest it’s about 110 outside right now. Thanks for watching. Let me know how yours works out.
Jay Visnansky
I’m in Peoria, AZ and work in my garage a good 4 hrs day I’ll definitely give this unit a go can’t be any worse lol.
Thanks again

@@smokinjoes9383 I’m just a few miles away from you and it does help !
@@smokinjoes9383 how did u like it?
@@glennjohn3919
Works just fine it actually knocks down the temps in the garage at least 10 degrees makes it much more comfortable that’s for sure.
Thanks again for sharing your video.
Joe
Like your sense of humor.
LOL ! Thanks.
Anyone know how long a full tank of water will last in the 450 square foot cooling system?
I found my full tank only lasted about 1 to 1 1/2 hours Brenda. I was always checking it and adding more water before it got too low. Your time may vary from what I had. Just keep checking it. Hope that helps somewhat.
Having the garage door open like you do, it would be difficult for any until to cool any room since heat is entering from 90% of the door opening. So if you are going to have the garage door open, I suggest installing a small portable wall under the door to the floor. Block off the entire opening other than two small opening for air intake and the other for exhaust. One opening for the air intake to the cooler. The other to exhaust the air to the outside. You must use 100% outside air for your unit’s air intake. Using indoor air and recirculating through the unit defeats the entire process. However, if you have a window in the garage, use that as your exhaust and only have one opening in the partition. As it stands now, you’ll never bring down the temperature much since hot air is entering from the same door opening you are conditioning the air. Also, in order for evaporative AC to be effective , there needs to be an air change in the room or home every two minutes. So, assuming the following and keeping the math simple:
40O sqft area x 10’ ceiling= 4000 cuft
Air change every 2 minutes = 4000 cuft / 2 minutes = 2000 cfm cooling capacity.
As it now stands, the evaporative cooler should have at least a 2000 cfm blower capacity. I don’t think the unit you have comes close to that figure and is undersized. The method I provide here is the standard way of calculation evaporative air condition sizing. Some will use an air change every 2.5 minutes as opposed to the 2 minutes I used. If 2.5 minutes used, a 1600 cfm unit could be utilized. Even at this size, your unit is still too small.
Also, as humidity rises, the evaporative AC becomes less effective. With 110 degree outside air and 10% humidity, you can probably achieve an 80 degree indoor temp. As humidity rises to 25-35%, your indoor air temps will range from 85-93 degrees.
Thanks for that detailed reply J Armstrong. Since the video, I have taken steps to block more of the garage door opening just as you suggest. I’ll probably be upgrading to a larger unit before too long. Thanks for watching and posting.
@@JayVisnansky You’re welcome. Just remember evaporative cooling works by moving very large quantities of air to achieve the cooling effect. Some folks will use evaporative cooling with refrigerated AC at the same time. Big mistake. Refrigerated air removes moisture from air, where evaporative AC add moisture. It will be the removal of latent heat from the water vapor that will drive up energy use in the home if both types used at same time. Use one or the other, but not both at the same time. Remember to keep a window open on the other end of the room or house when using evaporative AC.
In one house I had with both evap and AC, I had upducts in each room of the house. I didn’t have to have any windows opened. Those worked out real nice.
@@JayVisnansky upducts function the same way an open window does, except air is blown into the attic space reducing the temps there for evaporative cooling only. Don’t use with refrigerated AC. You’ll end up using much more energy.
Refrigerated AC depends on recycling conditioned air to be recycled through the coils to maintain temperature. However, a little outside air is required for air quality purposes due to CO2, off gassing from VOCs, radon, etc. But not to the levels upducts provide.
Great review I just bought this unit. Was hoping to use it in my bedroom. Would I be able to use this in my bedroom with my bedroom door open? Or do I need to open my windows as well?
I use it for my bedroom - I’ve had no issues with the bedroom door open, though your mileage may vary on that one. Can’t hurt to open a window in addition to it.
Just crack open a window opposite side from the cooler.
@@Cole-gq5cc is it really loud ? I also want to get one for the house but not if it’s super loud lol
Thanks for the review
You’re welcome Dario. Thanks for watching.
How easy or hard is it to clean/maintain the inside of this thing? It doesn't look all that accessible. Worried about mold buildup.
Well so far I haven’t needed to clean it. Probably a little beach would do the job. But I do make sure it’s empty after I’m done using it. Thanks for watching.
It would work much better with the door closed. When you heat or cool your home, do you leave the doors and windows open?
Hey Bill. Actually with a evaporated unit such as these, you do need to have a door or window open. It does seem counterintuitive, but it’s true. Thanks for watching.
that is not true for evap coolers, you need to cycle air out or it will not cool as well as the humidity level increases... thermal dynamics...its a science.
How does the hose work with it? Do I have to have the hose on the whole time?
You can first fill the tray with water JPR and then run the cooler. You’ll see how fast the water is used. Then based on that used, you’d connect the hose and then set the drip rate of the hose based on the first step I mentioned. At least that’s how I did it. Hope the makes sense.
I have a 160 sq ft building would this work?
Yes it should work for you. My area is 400 sq. ft and this unit did just OK. So yours being 160 sq ft, I would think that this unit would work. Thanks for watching.
@@JayVisnansky thank you
A ~100 watt water chiller will likely get the room into the 70s.
I’m putting in a mini split system this Fall. That’ll work !
I bought it for the garage, but now I am wondering if cats from the street or raccoons may come in. I have a fish tank in my garage. I am in a very humid environment. Hope it works.
I don’t know, Tessloneill. Evap coolers aren’t really made for very humid environments. You may want to check that out. Thanks for watching though. Hope it helps.
Great video 👍
Thanks Bob ! And thanks for watching.
I would bet if you put the garage door down to just a few inches it would work even better. You were letting a ton of hat air into the garage area.
You’re right ube2slow and I did just that, lowered the garage door to just a few inches. After trying a few things, that worked the best. Thanks for watching.
I currently have it in Pump only and the fan isn't running. Does that mean it's damaged?
Here’s the settings Ricardo;
@@JayVisnansky Hello Jay! I appreciate the help, I already have it on High with Pump but it doesn't sound like pump is working, doesn't sound loud at all.
@@ricardovaladez9093 Mine isn’t loud either but I can hear the water running through it.
nice review thx
Thanks c1catwoman. Thanks for watching too.
How much was it?
About $190 at HD Sam.
@@JayVisnansky thanks for the reply & the review
Just purchased one for $139.00 at Home Depot today
@@beccalynn5593 That’s great Becca ! Hope it works great for you too. Thanks for watching.
Your garage door is open to much and you should move it away from the garage door, it's pulling in hot air from outside and trying to cool hot outside air. Move it to the opposite side of garage. You'll see a huge difference.
Thanks for the suggestions BrianandRosa. And thanks for watching.
Would the next size up swamp cooler be too much?
For what size room John ? For a 20’x20’ garage? No. The next size up wouldn’t be too much.
@@JayVisnansky I have a one bedroom apartment so I was trying to see which size would work for the area. It’s maybe 800 square feet but ceiling is 9ft. I do have an a/c but feel like a swamp cooler would be cheaper to cool the dogs down during the day.
@@marathonbaker The biggest factor is the humidity at the air intake (cooling power) and the room (comfort/health). The difference between 30% and 60% humidity is ~ 10F in the water temperature. You need to adjust the windows' opennings to keep the humidity down. Preferably, place the cooler near one of the windows. If your area is really dry, try using 2 coolers ( one in the bedroom and the other in the living room ). The big coolers may be too loud for you in the bedroom ( 2 smaller coolers may be better ). Big cooler noise is usually in the less annoying lower frequencies ( maybe not for you).
@@rob4197 yeah just started using it this afternoon. Got the mc37m. I don’t know if I have big enough windows to have a larger draft. Have the back door screen open where the cooler is, and large window about 30ft in front wide open. Still was showing 66% humidity so I just shut the pump off and see if the fan will balance the temperature. Not really hot yet, tomorrow is suppose to be in the 90s
@@marathonbaker External wind direction/speed can have a huge impact. Your indoor humiiidity is high ( impact comfort/effectiveness). What is the outside humidity? How much bigger is the window openning (outlet) compare to the door openning (inlet)? You want the outlet openning to be 30-50% bigger. To encourage airflow, place a fan a few feet from the window to push air out ( don't place the fan on the window like an exhaust fan - pushing the air out is much more effective).
Does pump have to be on
I run it on as that’s what pumps the water over the pad which the fan blows air thru. That’s what outputs the cool air. Thanks for watching and hope 5hat helps you Raquel.
Next time you use it try adding ice ( sonic or chopped ice) and or cold water to reservoir and let me know how it works.. Should make difference.
I did just that Thagreat1, I added ice cubes to the reservoir. It did cool the air coming out but the ice didn’t last very long. But I just added more ice. Thanks for watching.
@@JayVisnansky ok.. o ordered the mc37m model 3100cfm and 900sqft coverage. Going to use that one for outdoor covered patio area. I'm down here in Louisiana so I'm hoping it can manage through these summer heat waves.
@@TheThesweetgee I’m here in Arizona so I don’t have to contend with too much humidity. These units work the best in a lower humidity environment. Best of luck to you Thagreat1.
Close the garage door
I think you should close that garage a little more
Done ! After experimenting with the opening, I agree, and closed it a little more. Thanks for watching.
Good, but loud.
It is loud Doc. But it’s at least in the garage with tools making noise too. Thanks for watching.
You try putting ice in it? Would you recommend for a bedroom? thanks man!
I did put ice in it Brent. It cooled the air blowing out of it somewhat. I’ve only had the unit on high so far and it’s loud at that setting. And it’s in the garage. So at least on the high setting, I feel it’s too loud for a bedroom. Hope that helps you. Thanks for watching.
@@JayVisnansky it certainly does help. One last question-What happens if say you fall asleep with the pump running/evaporative setting on? Is there an auto shut off that switches over to fan? Im afraid of burning out the pump. Thanks again!
@@MrBod4life There is no auto shut off Brent. There’s a water view in front of the unit and I’m always checking that while it’s running. I haven’t taken the time yet to hook up a hose to the unit. With that, the chance of running out of water goes away.
@@JayVisnansky Yea and like I said this is going to be in my bedroom lol no hose hookup there. I think this is the most concerning for me if say i have it running on that setting and then I fall asleep or something. Is there any warning sound when it gets low or any indication that the water needs a refilling (besides the fill line on the front of unit)? Also, do you use filtered water or tap?
@@MrBod4life No warning that I’ve come across so far Brent. But it’s been hot here while I’ve been using it. Most likely on a lower setting and not as hot, it wouldn’t use as much water and once full, could last the night.
You have to close your garage door!
I found the optimum opening to be about 6 inches Julia. It’s an evaporator cooler and it needs that outside air. Thanks for watching.
Close the door/window if you want to humidify the room. In freezing dry winter area ( because of heaters), people use the cooler as humidifier. Good for your health and plants.
Get ready to embrace the stickiness and humidity. ..try it in utah these swamp coolers are a sham.
Here in dry AZ it works just fine. But it would never work in high humidity places. Thanks for watching zoolo.
It's not a sham, it's science. If it's really humid in Utah, then the evaporative cooler, meaning it puts humidity in the air, isn't going be able to add any additional humidity in. That's the principle on which these evaporative coolers work. Now if some place sold you one saying it was going to change your life in Utah, well, I'd wager THEY are the sham for knowing how they work and just trying to make a buck off you.
In very hot, low humidity areas, these work very well. If it's normally dry in Utah, but happens to be a humid time, then these ALSO will not work; high humidity makes these useless. It's just the way they operate. Of course, you also need to keep a door or window slightly ajar and open one on another side of the room if possible to keep a current of air flowing through which helps the evaporative cooler do it's job and make you comfortable.
Looking at the average humidity from 1961 to 1990 for Utah, July is the lowest with 36%, and most every other month is over 40% which makes an evaporative cooler of little effect as you found out.
@@redemptusrenatus5336 You’re spot on about these not working in high humidity areas. I live in Phoenix so I’m able to use the evaporator cooler thru most of the hot months. Thanks for the update.
Pump died in less than a year. Do not buy
Geez, that’s not good Richard. Mine is still going ok but I haven’t used it yet this summer (2022). Good to know though. Thanks.
So, unless you're sitting in front of it, it's useless.
Pretty much. Unless it’s in a small room.
Great review I just bought this unit. Was hoping to use it in my bedroom. Would I be able to use this in my bedroom with my bedroom door open? Or do I need to open my windows as well?
Opening the bedroom door would certainly help Jerry depending on how big the rest of your place is. How about opening a window in another part of your place and have the bedroom door open ? Make sure the unit doesn’t run out of water during the night Jerry. Thanks for watching.
Jerry if you want your door close and window close try putting a Up-Dux in the bedroom ceiling that will be your door worked for me so far have a swamp cooler put a up-dux in my living room
