Every year I install this sunsail to shade my ac unit.
-
IIRC, my AC guy said the vertical throw of those units is far higher than that, I wonder if that translates into it sucking in more of it's own air (less efficient, higher cost)? Then again, UV seems to destroy everthing...
Heat rises so the plume these put out really is tall, the buoyancy of air does most of the work – put a fog machine next to it and you'll see it reach higher than the house.
The biggest benefit here is probably the shade to the siding, I'd focus on that (read: more trees) going forward instead of a black mesh shade that will absorb more sun and radiate heat back out.
-
And your HOA just lets you?
It’s a sad reality when people assume having an HOA is a given.
Feel bad for those subjected to it but I’d never purchase a property under the thumb of an HOA. Sucks how ubiquitous they have become.

If I told you that I had ten percent guaranteed return on an investment you'd want in too.
If you told me that, I wouldn't give you my money

Looks like the hot air would go up and out in 3 directions (plus through) and cooler air would be pulled in from the yard. Wouldn't it be interesting to test it with colored smoke? Or as you said a fog machine

Not all HOAs are bad... mine pretty much only exists to take care of our neighborhood pool, they've even loosened some of the few restrictions that had been in place since the 70s (restrictions on the type of fencing or sheds has been lifted). And it tends to run with a flat budget so our rates are very low for the area.

I reckon at least three
Boy I'll tell you what, 3 is alot.

Shading the condenser unit keeps it cooler and increases it's efficiency and helps keeps my electricity costs down. The sail is high enough and mesh like so that it doesn't trap the hot air. In fact it creates a slight wind tunnel effect. The shade it provides lasts during the hottest part of the day and a tree helpfully blocks the sun for the remainder. The unit is never in full sun this way. Keeping the weeds and other debris away from the unit so that it gets good airflow and cleaning the condenser every year also help with the units efficiency.
I'm curious why you rehang it every year and don't just install a retractable awning. Hell, putting some smaller retractable shades over the windows, especially the sunnier ones, would probably also save you a chunk of change on those bills.

If you're hot, they're hot!

wrote last edited by [email protected]I only recently learned these need to be shaded. People have started trying to come up with some solutions. No clue if this works https://cooleriscooler.com/

This is clever, but I don't think my HOA would allow. On the other hand, today was my once-per-three-year day to clean the coils, and boy do I hope that made a difference.

Same goes for heat pumps, a little shade can prolong their life and increase effectiveness.

For now.
The fun thing about HOA’s is that they can change and are absolutely dynamic. You never know when Karen’s crew is going to come into power.

Snow weighs quite a lot! So it must come down after a/c season is over. This was $20 4-5 years ago. I wish retractable shades were in the budget, that would be awesome.
-
Have you been able to quantify how much more efficient your unit is because of the shade?
Sadly there are just too many variables in play. Many other changes have been made to help keep costs down such as different thermostat settings, extra insulation, and duct sealing. It does all add up to quite a bit of savings.
-

My neighborhood is just too dull to have one I guess. Although once per month the city workers come and pick up leaves and sticks if you place them by the curb, which is pretty exciting.
-
Nice!
Do you have to purchase a new sunshade Everytime? Or reinstall the same one? I wonder if a more fabric tarp would last longer.It's lasted 4 years so far and was only $20! It's a nylon mesh material that let's water flow right through without absorbing it so it doesn't get too heavy.

This is interesting. Gut says that it does increase efficiency. Thing I'm questioning is by how much?
Anybody got numbers or a good educated guesstimate?

Shit, my AC unit is on the south side of my house. Should've built the house with the furnace on the north side.

Makes me think of this gem
