Now we understand why our grandparents surrounded their houses with large oak trees for shade. Summer shade and in the winter without leaves the house would warm up.

[@eegles]

Cargo ships are going back to sails, housing is trending back towards passive heating and cooling design.

[@morganrussman]

Yep. Which is why if you notice my parking habits if your ever with me, your going to notice that in certain area's, I'll try and park in shaded area's during the summer, and in known sunny areas in the winter. Especially if your in those sinarios where you need to get frost off your windows and you know you have a little bit of time for the sun to do it's thing before you take off somewhere. Edit: ok, so, while what i said regarding me parking in certain spots is true, sometimes that isn't always practical. I have one of those things that you put in the windshield that i will put there during the summer, and in one perticular parking lot in a perticular area, I was able to park my cars nose east or west depending on the time of the year. Unfortunately, that lot is presumably now a paid parking lot and doesn't allow for overnight parking (although, what i said had not been confirmed with parking enforcement, and, the vehicle's that are parked in the lot seem to still be there in the morning. at least, that's the case right now in late February of 2024).

I'd highly encourage anyone reading this to spend the time to research installing mini-split systems DIY. With the rates HVAC companies are charging, you can literally save yourself thousands for a dozen or two hours of research. Like most watching these videos, I'm a software engineering nerd, and knew the biggest gatekeeping obstacle for DIY HVAC is the EPA 608 test. With a few hours of study, the test is easy, and then it's 100% legal for you to do your own HVAC work. I passed that and then did a fairly involved 18K BTU ducted mini install in my attic (3 rooms from a single unit). I was quoted $25K+ for the install, which I did for

[@Capturing-Memories]

The down side of mini split is that for big houses with a lot of rooms you will be running a lot of refrigerant lines across the rooms, Forced air duct system is much easier especially if the duct system is there and you are only replacing the condenser and the evap, My 4ton system cost me around $3500 and two weekends, I had to borrow the tools though from a friend but buying them is not expensive.

[@stucorbishley]

How common are inverter based whole home AC units in the US? In South Africa splits are overwhelmingly the most common, and the downsides are obvious with some homes and buildings having a long complicated runs. However at least with modern splits, most of them are inverter based and are really efficient and have super low inrush current. A win when the grid is out and have solar/battery backup.

[@Capturing-Memories]

@@stucorbishley You mean heat pumps? They started to spread in the US, They are just not common in cold areas, The heating mode requires additional furnace or electric element in the air handler to supply heat whin the heat pump can't keep up with the cold weather.

The window units that Dave (8-bit guy) uses are inverters. I have one too. They're very silent and pretty powerful and they allow a lot more visibility through the window, and allow the window to open and close when they're installed.

[@ka7hqp182]

A major fail as day 2 would start with about no charge left in your batteries as night 1 would have depleted them unlike the charge that was available at the start of the test. An overcast day would have depleted them during the day. Time to look into evaporative cooling as it requires less power but requires water and only drops outside temperatures 30 degrees max for a single stage unit.

[@neutrino78x]

@@ka7hqp182 Indeed, I feel like more batteries would help a lot. That's the big problem we have in California. We get a shit load of power during the day from the sun. 15 GW. (well, at this very moment, 12.4 GW. Sun is not very high in the sky yet.) But we don't have enough storage to go through the night on batteries. YET. We're working on that. personally I figure we want about 216 GWh of storage, that would output 15 GW for 12 hours. But I believe the current goal is to get to 100 GWh, which would output 15 GW for roughly 7 hours. Which isn't bad. There's a company called hydrostor from Canada, they are building us some facilities that will store power in the form of compressed air. They dig a cavern underground, and put water to maintain the air pressure. It's like pumped storage, but not requiring a naturally occurring geography that's favorable to pumped storage. 🙂 Hydrostor's two facilities will be nowhere near 100 GWh though, we have to keep building more facilities. Of course solar isn't our only source of green power; we also have the world's largest geothermal facilities, which currently output 800 MW but they are being upgraded with some new plants that draw from the same heat source. (there's a huge blob of magma right underneath the north end of the San Francisco Bay. It causes naturally occurring steam underground.) Ultimately with the upgrades, "The Geysers" will output around 1.3 GW, 24/7 (no batteries needed). The other big geothermal source we are working on is the one down by San Diego, by the Salton Sea. Controlled thermal plans to build 1.1 GW of geothermal there. Some of the power will be used to extract lithium the hot brine. They think there is enough to get 300,000 tons of it every year for the next 100 years at least. California also has a lot of hydroelectric power, and we have one nuclear power plant. Unfortunately there are a lot of people not understanding the benefits of nuclear and basically afraid of it, so it's going to close down around 2025. If we get the geothermal fully built in the Salton Sea and Geysers areas though, that will replace nuclear as baseload. (I was a submariner, so I definitely support nuclear power. As the Captain of the USS Nautilus said, it is a "remarkable" form of energy.) 🙂

[@drCox12]

Advice from Europe: In order to keep heat outside the house in summer and inside the house in winter, I recommend upgrading your windows with roller shutters. A good window can insulate against air (temperature, humidity, noise) but it cannot insulate against the energy of light. Everybody knows how hot an inside floor or a window sill can become when the sun is shining on it through a window. Blocking (and reflecting) the sunlight will help to keep your house cooler and as a result you can reduce the amount of electrical energy needed for air conditioning.

[@Dhampy]

We like to use window quilts in my part of the US, the cold part of the US. But they work extremely well for keeping heat out as well when backed with white fabric. Combined with modern windows that filter IR and UV, at least until the gas insulations leak out, reducing the amount of overall energy outside of visible spectrums passing through, it works even better. You can also get treatments that reduce visible wavelengths, like polarized films... but then if you wear polarized eye glasses, you may have trouble seeing outside depending on the direction of the polarization in each.

Triple glass windows CAN insulate against heat. I can be in the sun coming through my windows and feel NO heat at all on the skin, and everything it shines on is completely cold. And you still get all the sunlight.

[@aquilux-vids]

Two big things that should be considered before you decide to up your power capabilities. 1: How good is your thermal envelope? you might get significantly more effect if you spend your money DIY or even professionally upgrading your insulation. Air leaks in windows and doors among other places are a huge contributor to heat ingress, the next biggest being heat moving through poorly insulated walls/ceilings/floors. This is probably one big reason you couldn't cool your bedroom to your liking, the window was not sealed and despite having a two hose system it's still likely heat was getting in. 2: Shade shade shade shade shade! That was the whole reason why people planted those trees that are blocking your solar power, but trees aren't the only solution. Hell, even your solar panels could be lowering the heat input through your roof if you give them a nice air gap between them and the roof. This also helps keep them cooler and more effective in power production. And then there's that wall on the side of the house that gets hot, aside from checking/upgrading it's insulation, find yourself some shade net and hang it from your eves or otherwise use it to intercept the sunlight and give your wall a good couple feet of breathing room from the brunt of the sunlight! Bonus: If you can, and your insulation is good enough, get your ACs working overtime early in the morning. The cooler air outside makes them more effective at rejecting heat and more efficient, and you can store energy in the form of an air battery in the temperature difference between inside and outside. The lower the inside temps at the start of the day, the more of a head start your ACs have. This is also a great idea if you have peak and off peak consumption pricing for overall, if you have good enough insulation blasting your AC at night when the power is cheapest will reduce the cooling you need at peak or at least delay your draw.

You can even get solar panels that use unused solar energy that the solar panel can't absorb as electricity and uses it to heat water running through them, which not only boosts the solar cells efficiency but allows warm water with no power or gas in the winter without drawing from batteries

[@kylexj1]

Hvac guy here, you'd be amazed at what the materials alone are to install a central a/c system, labor varies greatly by the outfit.

[@tterbo128]

Thanks for the rant on AC, that's a good idea.

Some other reasons are: tradition, looks, and a central control unit. One interesting advantage of multiple units is it, in theory, have a more accurate reading of the room temperature and essentially eliminate hotspots.

Very entertaining video. One thing you might do (and make a video about it) is to get a professional energy audit, where they use a blower door to do a leak test and use FLIR cameras to find voids in your wall and ceiling insulation. Adding more insulation is usually the best ROI to improve the comfort of the house and reduce your electrical usage. Most older tract houses have pretty poor insulation in the walls and ceilings.

I have one of those 8000 BTU Midea window units. Since getting it, I’ve learned a bit about Midea. The smart bits are actually used by a lot of companies and they allow for LAN based control without the use of cloud if you install the right addon in Home Assistant. Now, yes, the Midea system is going to be way more efficient. A bunch of them will be way more efficient. It’s not because they are window units, per se. It’s because they run variable speed compressors while the majority of central HVAC systems are not variable speed. They’re either on or off. And firing them up is a massive spike in power draw. But in Home Assistant, where I can see charted periods of when the HVAC runs and when the window unit runs, the window unit is almost always in “run mode” while the HVAC cycles when it’s below 100F outside, or just runs at full when above 100F outside. Logging the data in Home Assistant, I find many periods where my window unit is using as little as 100W, but maybe hits up to 400W or so. It’s a 710W unit, but I leave it in eco mode. The room I use it in stays cold. Midea makes mini split systems. They have options for ceiling cartridges and the traditional wall systems. I plan to buy a house in the next few years and I really want to buy one of their big ceiling cartridge based mini split systems. The evaporator part still runs a variable compressor like their window units so you get a lot of extra efficiency there.

[@tschuuuls486]

If you want to go for mini splits (with ceiling cartridges) also look at japanese brands. Mitsubishi (heavy industries) and Panasonic are higher quality unit's in general. Midea is a chinese low cost suff (not that it's terrible :D) also sold under a ton of other brands. In regards to the smart home stuff: A lot of stuff just uses Tuya modules. They supply the infrastructure and hardware to do dirt cheap wifi/zigbee integration for stuff.

[@gmirwin]

I use window units. There are advantages and disadvantages, as in anything. (Disclaimer: I am not an electrician or an A/C tech or anything similar. Also, I'm in the US so what I say may not apply to other countries.) Ideally each window unit should have its own separate circuit. If possible, they should be 20A circuits instead of the standard 15A circuits. Having a 20A circuit also gives you more options. You can get a more powerful A/C or even one with a built in heater since both of those will draw more juice than a 15A circuit could safely supply. A 20A outlet (female) will accept a standard 15A plug (male) but not vice versa so you could still use a unit with a normal plug. 20A circuits aren't just a special outlet, they also have more robust wiring and a special breaker. Of course, that's the ideal and most people just plug them into regular outlets. That can overload the circuit. If you plan on changing over, I would have an electrician add a 20A circuit to each room where you plan to add a window unit. At least do it for the larger ones.

Speed is controlled based on evap coil temp (don't want to slug the compressor or freeze the coil) and dewpoint. No use removing latent load (humidity) unless there's a need for it. Likewise, if there's heavy humidity, it basically becomes a large dehumidifier and focuses on moisture removal first, temperature later. I would have gone with an adjustable TXV valve but that was going to get complicated. The cost was minimal to do this and far cheaper than the ECM motors HVAC manufacturers use in the USA. Far better performance and comfort as well.

I think if the refrigerator had been prioritized a bit more it could have sustained itself for a full 24 hours - that's a significant achievement! Furthermore, your studio building seems pretty close to being able to endure a day or more without power. Perhaps a strategic move would be to enhance the solar and battery capacity there to provide a safe haven for your family. Meanwhile, the current setup in the main house can be utilized to maintain temperatures below 95 degrees F (the recommended ambient maximum for refrigerators) ensuring the safety of your food. Echoing some previous comments, given common building practices in recent decades, I'd speculate that enhancing the insulation in your main house might offer the best return on investment. This would reduce the external heat influx, making it more efficient for your house system to maintain desired temperatures.

[@j-fharbec379]

Wow, nice experiment! Here in Hungary, the average solar panel installations are around 5-7 kW. We can also request a 10-kW system, but that is already very expensive. I'm amazed that you managed to pull this off with such minimal solar power. :)

[@krisztiannemeth6148]

I guess it's because this 5-7-10 kW would generate approximately the same power as used by the household **if averaged over a year*. He could hardly charge his batteries, and basically he just used the solar energy to some air conditioning and the fridge, and it only lasted as long as the sun was shining. He used up the batter power from the day before, and that was it.

Central A/C condensers (the 'outside unit') cost quite a bit *because* it's the same as 4 of those 12k units. It has a huge compressor which is packed with copper coils and then it runs the freon up to the attic A-Frame and back down which is more copper tubing. There's also an electric motor for the fan and a radiator, all inside a casing. As for the attic unit, there's the A-frame which gets the cold freon and it likely has a heating element which uses an electric motor on a squirrel cage fan to blow the air into the duct work. The metal casing is insulated so it doesn't form condensation on the outside. The pan you mentioned isn't for emergencies, it's a drain pan as the A-frame forms condensation from the humid house air. There should be a pipe draining somewhere, often outside or into the shower/toilet breather pipe.

I loved seeing your attic because when I lived outside of Plano that's exactly what my attic looked like - a series of crazy ducts angled oddly and held together with tape.

So there's no place to go for those ducts except in the attic where they're installed with an M C Escher geometry.

[@mysticgreg]

Same deal here in south-eastern Australia, I think there's a lot in common with our construction to Texas. That attic shot pretty much looks exactly like the roof space of my house! With the exception that our gas central heating system is up there, not A/C. We have decommissioned the gas heating and just use reverse-cycle splits to heat the house which work great, and our energy costs have plummeted as a result - gas is extremely expensive now here but solar electricity is plentiful. A/C wise, the splits also keep the house beautifully cool, especially when closing off unused rooms and turning on the ceiling fans.

[@CommodoreFan64]

Same here in my part of South Carolina right on the GA border, where the soil is too sandy to have a basement in most of the homes, so the duct work is either in the attic, or under the house in a crawl space like mine, and it's a nightmare to work on, that is if your not doing window/floor units, or mini splits.

Note that even if you had a basement in Texas, it would still be best to install HVAC in the attic. Cold air sinks, so placing the vents / intakes / machinery in the attic.

I added 18 inches of blown insulation to my attic when I got solar (for a total of almost 2.5 feet). It was measured at R40 before and R80 after - and It barely made a dent. Texas bakes in the summer and no amount of insulation changes that. I built an addition onto my house and did a full spray foam envelope. It is no better at slowing the oven of a July day in Dallas. Assuming no one in Texas has thought of adding insulation to stave off the heat is insane.

While that might be useful for the theoretical power outage that he tested here, remember that he started off the video saying that he was trying to INCREASE his power consumption lol

[@joshpayne4015]

Insulating your attic is valuable -- but to go along with that, proper attic ventilation is critical. If you vent properly, you can reduce your attic temps to (hopefully) closer to outside ambient, which will reduce the amount of heat your insulation has to resist heat radiating down into your living space. They go hand in hand. If your attic isn't properly vented, all the insulation in the world will not help like you want it to. You can also install radiant reflectors (foil looking things) to help as well. They're all complimentary approaches.

This is what we do (In FL). We may not even use an A/C.

I'm sure we could have made it the same 2 weeks with a window unit in one of the rooms if we wanted to, but the truth is, even at 109F, if you open your house and run fans, you would likely still survive, albeit you would be really uncomfortable. (I also had another 50 gallons of gas in cans, our other car topped of, and the truck had 30 gallons to start... all in all I think we had about 100 gallons of gas which would have lasted us 2-3 months even with an A/C on in one room).
