—”What no back-up generator?”
That brings up a sore point.
With the new high-tech boiler (more computer than boiler)
I upgraded to a new EM inverter Generac, also portable for other use, still can carry the boiler and pumps and more...
But no 220VAC!! like the old generator.
But I would NEVER run any high-tech ANYTHING on the old generator. Voltage and frequency with the RPM like a seasaw.
—”Install/assemble, open valves, done.”
Not as fast as that Mr Cool guy, but close.
Time is money and you pay one way or the other.
Well done! Your labor and your smarts saved you thousands of dollars. Now just find a way to get your new arrangement to charge your EV.
—”I would have run the 30 inch vacuum over night as well”
A fun tidbit: the width of the needle on a mechanical vacuum gauge is 10,000s of thousand Microns of the face scale on the gauge.
To fully remove any moisture, holding at sub 500 Micron is needed. For noncondensable, you may need a purge condenser or active flush?
That said my brother’s unit and millions both of others work just fine.
—” Now just find a way to get your new arrangement to charge your EV.”
No EV yet and BIG GOV is doing everything to discourage their use IMO.
Here in Illinois, they have added a new EV tax because not using gasoline, and pressurizing the EV cram down pushes more poorly designed crap.
Thinking I’ll let others be the beta testers.
Point is, those mini split systems, they come sealed and pre-charged with freon. If you buy it as a kit.
Can you even find R-11? That was the flush! Clean and dry even on a retube of a salt water condenser.
The micron gauges came out and I was in heaven!
We have split units in a few rentals. Love, love em!
My roof is 20 and I think it’s a 25-year roof, looks in pretty good shape. Every so often this neighborhood gets targeted with ads for the new metal roof stuff...
Well I finally read some of this stuff and it’s not only metal roofing they’re doing your whole roof with a heat sync type of material that reduces the temperature of your attic so in 5 years after I understand even more about this phenomenal new product I keep hearing about but ignored, maybe they’ll be more information and testimony.

Bkmk....split AC
AHave one of these PTAC units in our bonus room, above the garage.
considering a minisplit for the garage. Haven’t found anything that works as I want, and it is also my woodworking and reloading space.
A friend of mine recommended hotel style for us as well.
“I would have run the 30 inch vacuum over night as well. I hate air and noncondensables. Other than that”
A guy serviced our heat pump several years ago (R22), said there was air in the system and flushed it out by pushing though new freon, letting the old stuff exhaust in the air.
I thought wow, hope the freon police don’t come by. I never worried about freon in the atmosphere other than a tiny concern about R12.
Some trivia: America doesn’t allow flammable refrigerants. Many other countries do. Propane, for instance, can be used as a refrigerant.
Testing
My Image host suddenly left town?

Sub 100 microns and holding...
—” America doesn’t allow flammable refrigerants.”
R-290 that I added to revive my system tends to be flammable and is used in the USA, but is limited to a given volume.
Ammonia is used in huge systems everywhere.
And can be very reactave.
It all depends on your own individual factors - budget, layout, noise tolerance, degree of DIY capabilities. Both make sense depending on the situation.
One 30000btu for the living/dining/kitchen/FL room, which has its own outside unit.
Each bedroom is 9000 btu, each with its own outside unit, figuring that if one failed we can sleep in the other bedroom, while we wait for parts, or swap parts if necessary. They are now ten years old and am replacing the bedroom units, same size 24-SEER
Initial cost
$3k for both bedrooms including disco box, line set, inside/outside units, wire, drain tubes, line set covers.
$3k for the living room.
I poured the outside slabs and mounted the in and out units, the disco box and drilled the holes in the block walls. Electric drop lines from main box was run by electrician and AC guy I know flared the line sets, drew the vacuum and dumped the Freon. Total cost was less than $8k.
VERY quiet.
August electric bill is ~$120/mo to keep the house 78° & winter is about $80/mo...and there is zero insulation in the attic. I'll get to that one day this winter when it's not so hot up there and rent a blower to blow in 18” of pink panther.
I bought from ecomfort in Illinois. Both times, great service, very helpful, shipped to my house.
I say all this to echo your thoughts and to encourage others who may be considering options.
Thanks for the great article!
