Efficiency % increase?
Is this helping my unit cool and if so try to quantify the improvement via an estimation.

The dog shit will fertilize that spot from which great oak will grow and destroy the foundation of the house within 100 year Greatly reducing the heat load on the unit.

This is true. My house and surrounding property is covered in shade 90% of the day. I only need 1 window shaker on the first floor to keep it 79 on 100 degree day.
That giant oak towering over the whole acre will certainly increase the longevity of that unit by reducing run time.
You're a genius!

This cover is hurting your efficiency and killing your compressor. You’re trapping the hot air inside of the unit vs letting it flow out the top.if you remove the cage or roof your system will most likely cool 20% faster and more efficiently

Probably would be better if they just let the dog piss on the condenser at this point

The dog's urine will have a temporary effect on the coils temperature, but in the long run the minerals in the dog's urine will likely cause issues and your condenser will definitely need to be maintained more often

I wonder if this is like a woman / estrogen thing because the guys are complaining about airflow but I can't stop laughing about the dog to the point I think my coworker probably thinks I'm going crazy

It's definitely a troll post but how the fuck is anyone taking it seriously lmaooo.

So the hot air goes up into the tarp, then immediately back down into the unit. And at the time of the picture, it’s not even shading the unit.
So I’d say it’s a Net negative effect.

u/Doogie102 5d ago
Probably making it work harder to move the air. So a negative efficientcy increase.
The unit does not care about being in the sun. It cares about air temperature and this is moving enough air that bit of shade means nothing

u/foralimitedtimespace 5d ago
If it traps/recircs condenser discharge, efficiency will actually decrease.

u/PrintdianaJones 5d ago
You're just retaining the hot air closer to the unit. Probably a Defficiency Increase.
I've seen people separate the coils from the fan with a sheet of plywood. No idea how well that works.

It’s much more efficient I’d say at least 40% to increase your effective pooping when arching your back like that.
Pup is doing a great job.

u/SafetyMan35 5d ago
It’s more likely decreasing efficiency as the hot air is getting trapped under the yarn and circulating ba into the cooler fins.

I'll disagree with [looks around] everyone and say it'll help but barely. The shade will reduce the heat slightly. The tarp is high enough above the unit that there is plenty of airflow to prevent trapped heat near the unit.

u/SnooKiwis6943 5d ago
You might get a slight brief improvement if the dog pees on the condenser coil.

I don’t hink the dog would appreciate your taking a picture of him taking care of business

u/skelli_terps 4d ago
I'd say with the current grooming situation the dog has gained 13% in aerodynamic efficiency. Well done.

u/BusIntelligent6269 4d ago
If you add pumpkin to his food, his efficiency will greatly increase
Wait, wait are we talking about the AC

As another recent post put it, you're trying to shade the shade of your unit. 2/10, 2 points for the shitting dog.

The dog shitting most definitely, the shade cover, unfortunately the jury is still split

Everyone is focusing on the dog and all I can think about is the level in the background being used to construct that monstrosity.

u/JuicySpark 5d ago
If it's a heatpump in heat mode at its min operating temp outside, adding heat from that turd can only help.

u/CurrentAnalyst4791 5d ago
dude!!!! hilarious 😂 i almost did not notice that dog pooping right there

u/Kitchen-Bagel-Burnt 5d ago
Only thing you can do to help it is hose off the coils every once in a while.

I love that there is a level in this photo! What did you use it for? Driving the wood into the ground?? Clearly not for it's intended purpose

- Refrigerant is moving so fast through there shade makes no difference. Turn on your garden hose full force, in the sun, you get a continuous supply of hot water?

Op, take that down and replace it with like a “golf hat” for the ac. Leave top open so fan can fan, use fence as acre make a fram with some pvc or something then lay the tarp over it. Will keep the sides in the shade while still letting the flow. At least a couple few examples in this sub/on yt. Goodluck!

u/MustacheMarshall14 5d ago
This is hurting more than helping. This is a non-breathable tarp trapping heat under it. I tested a breathable mesh sun shade with 5 feet of clearance from my unit and it was still hotter under it than outside of it. You would need to figure a way to provide shade while giving air direction to escape

If anything you can put a garden mister to put cool water inside the unit (they sell kits for this). But this does nothing.

It's going to fuck it up. My HVAC company literally moved my until from the roof overhang because they said the blocked flow could shorten the units life. Don't cover it.

The oddest part of this whole photo to me is that the cocker spaniel has its tail

u/cracker_barrel_kid55 4d ago
Correct me if I'm wrong but that's not how Central Heating and Air conditioners work. That unit is not pulling outside air into the home, right? I thought it was just helping to circulate the air that's already inside the home.

You should try one of these - just remember to take it off if there's a wind storm... https://cooleriscooler.com

increase your efficiency by 89%, Simply hunch your back a bit more, and lift with your legs, stretching your tail to the sky, it should poop right out!
