1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of “discuss” rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This isn't an advice forum

Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with “So” - starting a post with pointless phrases, like “I hope this is allowed” or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Every year I install this sunsail to shade my ac unit. (dullsters.net)

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.

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...

I doubt it. That's quite far and it's open so there's plenty of room for it to spread out. You wouldn't want part of your building to be in the air stream because the air from the condensing unit would heat it up, but it's fine if the tarp gets warm.

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.

Hot AIR rises. And it can also move sideways, and both are possible with this mesh. 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

Fucking smart

[–] Sunshine@lemmy.ca 5 points 21 hours ago

As expected for someone who uses a heat pump!

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.

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.

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/
