Designed for straightforward DIY installation with Airspool's Quick ’n’ EasyTM connection system.
Sized to heat and cool spaces up to 500 square feet in typical residential applications.
Runs on solar, grid, or hybrid mode, with solar power prioritized whenever it is available.
The HS12 uses Enhanced Vapor Injection technology to keep delivering reliable heat all the way down to -22°F.
Built for the coldest climates on Earth. The Airspool HS12 "SuperHeat" is our extreme-weather flagship — the same beloved Quick ’n’ EasyTM system with Enhanced Vapor Injection (EVI) technology that keeps you warm when other heat pumps quit. Same 5-minute connection, same solar/hybrid flexibility, same incredible guarantee — but engineered to heat your home all the way down to -22°F.

The HS12 isn't just a mini-split — it's cold-climate comfort, redefined.
While most heat pumps tap out when temperatures drop below freezing, the HS12 keeps pushing thanks to Enhanced Vapor Injection (EVI) technology. That means reliable, efficient heating all the way down to -22°F — without backup heaters, without space heaters, without worrying.
It's the same Quick ’n’ EasyTM system our customers love: solar-first hybrid power, a 5-minute connection, and the industry's best guarantee. But now, engineered for the harshest winters on the planet.
If you live where it actually gets cold, this is your unit.
To heat to such low temperatures, the HS12 uses a specialized power plug called a Nema 5-20R (20 amp, 120v). It looks like a standard three-prong plug except one of the prongs is on its side.
Going off grid? We recommend 1500 watts of solar panels to enjoy year-round comfort, wherever you live.
Your HS12 seamlessly blends grid and solar power so you never lose comfort. Solar is prioritized, and grid power automatically fills in as needed.
Most heat pumps lose efficiency — and eventually stop working — when outside temperatures drop below freezing. That's because standard compressors struggle to extract heat from extremely cold air.
EVI (Enhanced Vapor Injection) solves this. It adds a secondary injection cycle to the compressor that supercharges its ability to extract warmth from frigid air — even at -22°F.
The result? Consistent, powerful heating performance in conditions that would shut down a standard unit.
No backup heater needed. No space heaters. No worrying about whether your system can handle a cold snap.
Just reliable warmth, powered by the sun and backed by the best guarantee in the industry.
The Secret That Will Save You Hours and $$$
Installing a mini-split system typically requires a vacuum pump, gauge set, specialized wrenches, adapters, correct-sized screwdrivers, wire cutters/strippers, and potentially extra refrigerant. Plus, know-how, patience and time.
But not with Airspool.
We do all of that work and pre-install our patent-pending Quick ’n’ EasyTM valves at our US headquarters. So when your unit shows up at your doorstep, you just twist the connections!
With most mini-splits, you get what you get as far as line set length.
But not with Airspool.
Because we customize everything in-house, you have the option to customize the length of your lineset. All the way to 49 ft!
And, since we test all aspects (e.g. solar, grid, and a combination of both) before shipping, we know it's going to work for you. Because of this, you get an unprecedented 5-year functionality guarantee.
Imagine coming home to the perfect temperature in your room, no matter what season. With our Apple/Android app, you can control your air conditioning and heat directly from your phone from anywhere in the world. Or program the times you want and forget about it.
But if you're like us and like to have some physical buttons to press, you'll appreciate the remote included with your unit.
Because we give you:

Indoor Unit
Like every purchase you make with Airspool, your HS12 is backed by two industry-leading guarantees.
Take a full year to make sure your Airspool system is right for you. For any reason — or no reason at all — you can return it within 365 days for a full refund, and we’ll even cover the shipping back to us.
We want to take all the risk off your shoulders so you know you're making a good decision with Airspool.
Your comfort shouldn’t come with fine print. For five full years after purchase, we’ll make sure your unit keeps running like new. That means we cover all parts and labor.
Here's what to expect when we ship your HS12.
You'll receive your new HS12 in three boxes.
Weight: around 97lbs
Weight: around 29lbs
Weight: around 2lbs
Worldwide: Highly discounted shipping (when you enter your address at checkout, your shipping total will be displayed before you purchase).
We mostly contract with UPS for USA shipments. For international shipments, DHL, FedEx, UPS, or other carriers may handle the shipment.
That's not your problem! Remember you have a 365-day Buy and Try Guarantee so you can return your unit for any reason or no reason. We'll even cover the shipping costs back to us.
The indoor unit operates at library-level quiet and most people forget it is running. The outdoor unit is comparable to a normal conversation. The variable-speed compressor ramps smoothly and avoids jarring on/off cycling.
About 500 sq ft, which is ideal for a large bedroom, living room, studio, garage, workshop, or ADU. Need to cover around 1,000 sq ft in a cold climate? Check out the HS24 SuperHeat.
Yes. EVI (Enhanced Vapor Injection) adds a secondary injection cycle to the compressor that supercharges its ability to extract warmth from extremely cold air. Standard heat pumps lose efficiency and eventually stop working below freezing, but the HS12 keeps heating all the way down to -22°F. No backup heater needed.
Same unit with two key upgrades: EVI SuperHeat technology that heats down to -22°F instead of the MS12’s 5°F, and a 20-amp outlet requirement (NEMA 5-20R) instead of the MS12’s standard 15-amp outlet. Everything else, including Quick ’n’ EasyTM connection, solar capability, cooling performance, 12,000 BTU rating, and the guarantee, is effectively the same. If you live in a mild-to-moderate climate, the MS12 is a great value. If your winters are serious, the HS12 is the one.
A 120V, 20-amp outlet (NEMA 5-20R). This looks almost identical to a standard outlet but has a T-shaped slot on one side. Many homes already have these in kitchens, bathrooms, and garages. If you are not sure, check the outlet or have an electrician swap one in quickly and inexpensively.
No. The HS12 works perfectly on grid power alone. Add solar panels whenever you are ready. Many customers start on grid and add solar later to reduce their electricity costs.
About 1,500 watts, which is usually 3-4 standard panels. Budget around $400-$600 for panels plus mounting hardware. A little under is fine because grid power fills in automatically.
Most first-timers finish in 2-4 hours. The Quick ’n’ EasyTM twist connections take about 5 minutes. The rest is mounting the wall bracket, drilling the pass-through hole, and routing the line set.
Just a drill. We include a hole saw, drill bits, screwdriver bit, level, gloves, and all mounting hardware. No vacuum pump, no gauges, and no torque wrench.
No worries either way. Too little solar means grid power fills in automatically. Too much means the excess voltage simply goes unused without causing any problems. The system is designed to be flexible.
Absolutely. The HS12 cools in temperatures up to 131°F, identical cooling performance to the MS12. It is a full heat pump: heating and cooling, year-round, in one unit. The SuperHeat upgrade only affects how cold it can heat.
If the sun is shining, yes. Solar panels continue powering the unit. At night during an outage, you would need battery backup or a generator.
Clean the indoor air filter quarterly by rinsing it under water, shaking it dry, and replacing it. Vacuum the indoor coil and spray the outdoor coil annually. That is it.
Yes. The Quick ’n’ EasyTM self-sealing valves unscrew and reconnect without losing refrigerant. About 5 minutes each way. No HVAC tech needed.
Indoor and outdoor units, pre-charged 10-ft twist-to-connect copper line set, 120V 20-amp power cord, communication wire, wall bracket, remote control, condensate hose, and our free Quick ’n’ EasyTM Bonus Kit (solar whips, DC isolator, solar wire, hole saw, drill bits, level, gloves, and more). Everything except a drill and solar panels.
Shipping is highly discounted worldwide and shown at checkout before you purchase. You will receive 3 boxes: outdoor unit (around 95 lbs), indoor unit (around 27 lbs), and solar isolator (around 2 lbs).
