Introducing the Airspool MS12 (12,000 BTU) Quick 'n' Easy™ Solar Air Conditioner & Heater 
✅ Connects in 5 minutes—literally.  (Note:  We didn't say 'Installs in 5 minutes.'  It takes a while to mount the indoor unit on the wall, feed the lines through the wall, etc.  But once that's done, it's quick--and easy.)
✅ No HVAC tech needed.
✅ 5-Year Happiness Guarantee.
✅ Greatly discounted shipping.
✅ You pay no sales tax outside of Nevada.

And, for this year only, you can still save 30% off your purchase price via an investment tax credit by filing Form 5696 at tax time for systems installed prior to 12/31/25.  Take massive action now for this free money (the best kind of money, actually)!  Our IRS QM Code = T3N1.  (This is a new requirement for this year.)  And, you also get 30% off the cost of your solar panels and 30% off the cost of any installation labor.  Here's how to do it (as of last year, but now you'll need that QM Code for next year's updated form coming soon).

The Guarantee

You:
“Wait, so after the first-year Buy-and-Try period—where I can return it for a full refund, including shipping both ways—there’s another 4 years where you’ll fix the unit for free if anything goes wrong? No tech fees? No parts fees? No shipping fees? No Way! That can’t be right.”

Us: "Way."

This isn’t one of those warranties where we toss parts in your direction and hope for the best. If something goes wrong, we'll help you troubleshoot, send you parts at our cost and refund you for your time to install them as needed, cover all shipping, and even replace the unit if required. You won’t be stuck chasing help or paying out of pocket.

• Risk-free 5-year guarantee!  Return the unit in the 1st year if you're not happy to get all of your money back. Once you're happy, in years 2-5, we'll fix problems for free, or send you a new unit if we can't.  This applies as long as you personally own the product and are not using the product in a commercial or industrial setting. 

And in the first year? You’re covered by our no-risk, no-hassle, no-regret Buy-and-Try Guarantee. If you're not thrilled, return it for a full refund, including all shipping.

Are we crazy? Maybe. But not about this. We know these units are solid, so we’re backing them with the strongest guarantee in the industry. Your happiness is our happiness.

Connection in 5 Minutes—Seriously.

No vacuum pump. No nitrogen. No gauges. No torque wrench. The only tool you'll need is a drill.

With our patent-pending Quick 'n' Easy™ system, you:

• Twist-to-connect the pre-charged refrigerant lines

• Plug in the pre-installed power cord

• Snap together the communications wire

• Click in your solar lines using standard MC4 connectors

That’s it.

And yes—it’s portable. Move it to another room, another house, another state. Just unplug and unscrew, then reinstall it the same way in minutes.

What’s Included

Everything you need for solar-powered heating and cooling—except the solar panels:

• Indoor and outdoor units (12,000 BTU cooling / 12,000 BTU heating)

• Pre-charged (not pre-vacuumed), twist-to-connect refrigerant line set (3 meters (9' 10", insulated copper)

• Pre-installed 110v/115v/120v 15-amp power cord  

• 4-meter, 4-lead communication control wire

• Wall bracket, putty, and hardware

• Remote control (with batteries)

• 10-ft condensate hose

• 2” x 50-ft wrapping tape

• Dust caps for valve protection

• MC4 disconnect tools and extra connectors

• Clear, native-English installation instructions

Quick 'n' Easy Exclusive Bonus Kit:

• 4 ft. solar whips ($18.90 value)

• DC isolator box ($33.60 value)

• 10m solar wire ($45.65 value)

• Gloves, zip ties, electrical tape, 36" of insulation

• Hole saw, drill bits, screwdriver bit, and level ($75+ combined value)

• Every cord and wire pre-installed, every fitting test-run before we ship.  Before we ship, your unit will have been tested on solar, grid, and a combination of both powers, so you won't have any issues. We catch any problems before shipment to save us both time. 

What’s Not Included

• Solar panels & racking.
  You’ll need around 1,500W of solar (a little under or over is totally fine). If you are under, extra grid power may be required. If you are over, there may be some extra voltage that never converts to energy.  Either way, no big deal. 
  We don’t currently ship panels—they’re large, heavy, glass, and can’t go UPS like the rest of the unit. We’ll help connect you with a local supplier. Budget about $600 plus mounting hardware.

In Summary:

✅ Truly DIY
✅ Truly fast
✅ Truly backed by us, not left to you
✅ No tools beyond a drill
✅ No HVAC technician required

Give the Airspool Quick 'n' Easy™ a try—risk-free.
