Yeah you don't want to be one of those people who says they care so much about the environment and goes on about how bad everyone else is but uses natural gas for home heating.

You excuse yourself because others are not perfect. You are so pathetic.

As for my family, my PV generation is more than my home, cars and NG use. Yet I plan to put up *more* PV and conserve even more.

What is your excuse now ?
I'm not making excuses but it sounds like you are.
What's pathetic is someone who says they care soon much about the environment and global warming and uses natural gas for home heating. That's the most hypocrisy I have witnessed in a long time.
You should be a politician.

Well my at least 10 year old r410a 18,000btu/hr 120v mini split heat pump died.
Its not a contactor, not a capacitor, charge is good, purged non condensables.
It sounds like hell and the pressures are not right.
This one is probably about a 16 seer unit on account of it having a fixed speed compressor.
It probably wore out from being oversized and from lots of restarts. I didn't install it. If was going to install a fixed speed unit in this application I would have probably only went with a 10k or 12k btu.

The new one is 23 seer, 240v powered variable speed compressor that tries to heat pump down to -5F.
The old one gave up trying to be a heatpump at +5F. Both old and new start using electric heat around freezing.

I like to go big with inverter splits since I can leave them off all day, come home, start them up, cool the room down quickly then they throttle way back and give maximum efficiency.
But ultimately the off setting gives the best efficiency.

The old one is going to the local hvac shop to attempt a somewhat economical repair. Because reusing is better than recycling.

You can't decide, based on the above, that he's wasting energy. You would need more information. Best would be to test that approach against running the mini split all day on a power saving setting.

A consideration:

I pay Griddy, my energy provider $10/month to buy energy at cost via the ERCOT regulated energy system in Texas. We had 3 days a short time ago, that every kWh, for relatively short periods, cost around $13 - including the "ancillary" add on that ERCOT legally receives (yes, $13 - not a typo). I was able to minimize my costs by precooling the entire home late at night/early morning (about 1.5 cents/kWH) to about 70 degrees and then letting it float up to 79 degrees during the "peak" of the ERCOT systems power levels. It was still costly, but not nearly as most others that use such a contract. I'd doubt that this minimized the overall energy consumption, but certainly helps the overall operation of the ERCOT grid (and my wallet). I have saved 20-30% on the first year with Griddy compared to any other contract at the time I had to decide.

Eventually, as more users realize that maximizing late night/early morning usage actually helps the "grid" and as a result, they are able to save usage during the peak afternoons, that less "peaker" energy (think very expensive) is required - at least here in the ERCOT system which is likely similar to most grid systems.

V2X along with EV proliferation (talking millions) has the "potential" to actually help stabilize the grid - however is quite a ways off for many reasons. If I knew anything about twitter - #microgridforhomes :mrgreen:

^^ Well done !!

Demand shifting like you did works great with a good home envelope of insulation and air tightness along with an HRV/ERV for humidity control and air quality.

We've been doing this for 20 years: greatly reducing our grid consumption during peak loads (hot weather here) and doing more cooling in the morning and late at night. I remember poring through the regional ISO logs about 20 years ago, to get a feel for when local demand was highest and lowest, because they never made (or make) any effort to inform consumers about this issue.
