12vdc AC Compressor on Amazon, Looks interesting if you have an alternator to run it. Options

Just add Under Dash Evaporator, Condenser and dryer!
Example install, but mine is a Benling

I run an automotive AC specialist shop.
I deal with modern AC systems every day.
I have customers who have brought BRAND NEW vehicles to me that the AC doesn't work to their expectations to have a NEW vehicle fixed as the dealers cannot actually fix anything.

They just replace parts...

The only vehicles I've seen with electric compressors are a very few hybrids that have fully electric compressors. The common ones are the Toyota Prius and the Cadillac Escalade hybrids.

Both of these use a Mitsubishi compressor (the same basic beast) and are running 600 volts to the compressor.

Most other hybrids still use a standard compressor that is belt driven.

All ICE engines vehicles I've hit, even brand-new ones, use a standard compressor.
They are all variable displacement computer-controlled compressors, but they are NOT like a Mitsubishi electric.

A true electric compressor takes special care to repair as the oil HAS to be di-electric.
You put normal PAG in one of these and you kill the system INSTANTLY!

Toyota's suggestion for a poisoned electric system is to replace everything the refrigerate touches. ALL of it!
Dash out for evap, all lines, condenser, compressor, all switches, everything!
On a Pruis it touches 7K!
On an Escalade it's more...

I believe I could clean one of these out and re-use some of it, but it would still be massively expensive.


Each time you change power from one type (mechanical to electric and back) you will lose some efficacy.
If you could make a change at 100% you will end up being the richest person on the planet as this is the path to perpetual movement.

All modern ECUs reduce power loads (de-stroke and disco clutch on a compressor) above a specific RPM, throttle angle, and speed of throttle angle change.
So, when you hammer the throttle on your 2012 Chevy truck, it takes out both the compressor and the alternator instantly.
It will also take out the compressor with a serous engine problem. If the check engine light is flashing (bad!) your AC will not work...

The days of an AC system reducing power when power is demanded are long over. That stuff started happening in the late 80s and by 2000 power robbing was no-longer an issue.

I'd be DAMNED careful regarding the oil and system cleanliness when installing any fully electric compressor.
It would need to be "medically" clean IMO and I would make damn sure about any additional oil I added to the system.
I am especially leery of the claim on Amazon that "compressor is filled with oil and no extra is needed..."
How do they know how big your system is?

A modern Chevy truck needs less than 4 ounces total but a Tahoe needs 8.
Same compressor, same condenser, same puppy except one has an additional evaporator and 20 feet of lines and needs more than double the amount of oil...

I was forced to install 6 Chinese compressors last season as I could not get OEMs anywhere.
All 6 failed!
I know what I'm doing!
I lose 1 out of 200 OEMs...
So, a 100% failure rate versus a 0.5% failure rate.
You do the math!

When they failed, they came apart internally and trashed the systems.
So, it was not just replacing the compressor.
The repairs included finding an OEM compressor (or having the original re-built), replacing the condenser, desiccant package, expansion device, and a complete flushing of everything. Each failure would have been a 2k+ job by itself.

Chinese compressors have cost me over 12K!!!

I will no longer install Chinese compressors.

I might try an electric from a brand name company. These are Denso, Sanden, Calsonic, Harrison/Delphi, Panasonic, Diesel Kiki, Mitsubishi, and others.
Haven't seen electrics from any of those companies except Mitsubishi.


No-names get thrown in the trash...

I am looking into a retrofit using the Mits compressor from an Escalade for "pro-mod" street cars including the big assed battery. Have to figure out how to charge this battery via a house charger and I believe AC alone the battery would last 8-10 hours.
The Escalades take a long time to cool down but...
The Hybrids pump 35-degree air where the non-hybrids turn off the party at 45.
Mitsubishi beats Chevrolet (Denso) in this regard.
