01The big idea
Solar air conditioning, without the science project.
Most “solar AC” setups need batteries, an inverter, and net metering — you end up spending as much on the system around the air conditioner as on the air conditioner itself.
The MS12 skips all of it. Its DC motors run on the same power solar panels make, so panels plug straight into the unit. Sun out? It runs on solar first. Sun fades? Grid power fills in automatically. You switch nothing, manage nothing — and it works on day one with zero panels.
What you don't need
Batteries
Inverter
Net metering
Vacuum pump & gauges
Panels plug straight in. That's the whole system.

02How it works
Three ways to power it. Zero switches to flip.
02
Solar only Fully off-grid
Going off grid? We recommend about 1,500 watts of panels (3–4 standard panels) for year-round comfort, wherever you live.
03
Hybrid Sunshine first, automatically
The MS12 seamlessly blends grid and solar power. Solar is prioritized; grid fills in as needed. You never touch a switch.
Too little solar? Grid fills in automatically. Too much? No harm done. You never touch a switch.
03Do it yourself (really)
One drill. One afternoon. Six steps.
Most first-timers finish in 2–4 hours. The refrigerant connection itself takes about 5 minutes — by hand.

04The honest question
“Will the twist-connect actually seal?”
What goes wrong with normal DIY mini-splits
Refrigerant leaks from badly-made flare connections. Skipped vacuum steps. Moisture trapped in the lines. Installing a typical mini-split takes a vacuum pump, gauge set, specialized wrenches, adapters, wire cutters — plus the know-how, patience, and time to use them right. Get one step wrong and the system leaks.
Why the MS12 sidesteps all of it
We do that work at our US headquarters. The refrigerant lines arrive pre-charged and sealed with our patent-pending Quick ’n’ EasyTM self-sealing twist valves. No flaring, no vacuum, no moisture risk. You twist the connections by hand — the whole hook-up takes about 5 minutes. They even unscrew and reconnect later without losing refrigerant, if you ever move the unit.
Every single unit is tested on solar, grid, and hybrid power before it leaves our building. That's why we can back it for five years — DIY install included.

We waited long enough!
Moving off grid to the Arizona southeast desert was a big shock to our systems. Our first summer without any real power yet established was brutal. Although the power system we installed could handle most normal appliances, it just didn't have enough oomph to run air conditioning in our 1300 square foot doublewide. We've managed these last few years by doing some common sense heat mitigation techniques. Even still, when summer temps creep over 100 degrees, inside temps creep into the mid to upper 80s. We've been researching DC mini-split technology for awhile now and decided to pull the trigger with the Airspool MS-12 Quick and Easy. The kit included everything we needed except the solar panels which we purchased from an area supplier. All total, setting up and installing the units took less than half a day. The instructions were easy to follow and didn't require any in-depth electrical or plumbing knowledge. Looking forward to how it will handle those 100+ degree summer days.

Couldn’t be happier
Very easy to install. The instruction manual that Dave the owner of Airspool wrote covered every detail of the install. It’s written in plain easy to read and understand English. It even has color picture's showing how to do everything. The owner genuinely cares about his customers and his product. The best part though is connecting the solar panels. Oh my gosh having ice cold AC cooling my living and dining room while the plug is laying on the ground is incredibly. I plugged it into my killawatt for kicks and for when the sunsets. It was only pulling 2.8 watts. I’ll be buying two more units soon as I can afford them. One for my garage and another for the master bedroom. Thank you Dave for everything! Installing it was a rewarding and enjoyable experience!

Keeps my Phoenix garage cool
I’ve had the Airspool installed in my garage for a little over a year. I live near Phoenix so the temps in my garage during the summer have in the past exceeded 105 degrees routinely. The Airspool, in combination with adding insulation to my garage, has been a game changer. Average temp in my garage from June thru August this summer, one of the hottest on record, was 80 degrees with day time temps around 77-78. I run the Airspool on Solar during the day and do not normally run it at night unless there’s a project going on out there. We have a large freezer out there and it works much less hard with the cooler garage. My wife loves to go out and get in her cool car in the morning. And of course it makes the garage nice for doing various projects that I like to do.
I highly recommend the Airspool.

We could not be happier, loving our free solar heat/ac all day-light long.
We bought our first AirSpool in Sept 2025 and loved it so much that we bought our second one in May of 2026. Not only are they easy to self-install via the installation booklet, web and videos but the customer support is outstanding. The fact that you get everything save the solar panels needed to install this saves hours and hours of research and time. They give you the gloves, the drill bits and etc. Everything is so thought out in the self instillation kit. We have a 1998 square ft. home and have gotten our electric usage down to about 400 – 500 kwh a month due to the free heat/AC all day-light long. We only use it on solar most of the time. Last winter we did plug it in at night. So being able to use it in hybrid mode is very nice. We are amazed at how well it performs. We get full solar usage earlier in the mornings on cloudy days, which is unexpected. We think it’s because there is so much reflection bouncing off of the clouds. So if you think it works on solar only when the sun is shining, that’s not necessarily the case. We cannot recommend AirSpool and David VanZanten enough. Thanks so much.

So far so good.
My home HVAC has resistive heating coils to heat the house during the winter. This is a very expensive type of heating system. My heating costs were higher than my summer cooling costs. Normal KWh use without heat is 10~15KWh per day. Using the resistive heating, my use went to well over 45KWh per day. Heating with the Airspool Mini-Split, my electric use is less than 1/3rd the cost of the large HVAC unit. Now that I have my solar panels set up, my commercial power use will drop even more. I hope to see similar results come summer here in Florida. Installation of the unit itself was easy. The most difficult part was that I had some shelves that were next to permanently mounted on the wall where I needed to put the mini-split head unit. It took many more hours to get those out of the way, compared to the 30 minutes to hang the head unit. Setting up the outside unit was even quicker, and yes, using the included gloves, the Freon connections can easily be fully connected by hand, no tools needed. The only question is how long will the unit last? That I can't answer, but with how well it works right now, I hope I have many many years with it. It's also extremely quiet. At first, I thought there's no way this is going to output enough air to heat or cool my homes living area. That's totally wrong. The volume of air is more than enough to not need a high speed noisy fan. The unit looks great and works great. One of the best buys I've ever made for my home, and being on solar is just that much better.

Start up
I started the install about 9:30 this morning and have it running around 4 pm.
No problem at any point of the installation.
I had to get an accurate location for the run down a 5" wide strip of building along a set of sliders on a 4 season glass room. All good and cleaned up. Done

Easy installation with exceptional customer service.
I installed the unit in early September 2025. The installation manual was well written and illustrated. The install was straightforward and took about a day, the most difficult part was putting down a pad for the outside unit. Texted questions were answered quickly by a human, actually the owner.

Home Builder approved!
I’m very happy with these units. The install on the first unit took about 30 minutes including drilling the holes and installing the bracket on the wall. The second unit took about 15 minutes from start to finish and they both worked flawlessly. The install couldn’t be simpler.
The actual hook up of the tubing took less than the advertised 5 minutes. As a builder I’ll be recommending these to my clients for a great solution to get AC/heat into room additions or hot areas of their homes.
I’ll definitely be purchasing more Airspool units.

Amazing Technology / Amazing Mini Split!!
So far, I have bought two of these units from Airspool. I got one for my Master bedroom that is a pretty large bedroom. I live in Arizona where the temps get in the "one hundred and teens" constantly in the summer months. I have each one connected to 4 panels of 455 watt each in my back yard. Both Airspools BLAST out the COLD air like crazy!! I easily adjust the temperatures, turn on and off the units and a LOT of other stuff, via the app on my phone or tablet that works GREAT and FAST! In the HEAT of the summer, my bedroom is like a meat locker it's so cold! I love it that cold. During the night, it can take power from the grid using a standard 120 volt plug. I have mine connected a little differently. My mini splits are plugged into an Ecoflow Delta Pro each with two external batteries. This means that during the day, the mini split pulls ZERO watts from the Delta Pro and that allows it to charge using solar to 100%. As soon as the sun starts going down, the Airspool will start pulling from the Delta Pro. The Airspool will prioritize solar first, so as the sun comes up in the morning, it starts gradually pulling from solar. When the sun starts going down it starts pulling from the grid. It's really a brilliant system. The way "I" have mine set up, it gives me FREE col air and I'm not paying ONE PENNY for electricity to power my mini split units. GREAT units and I HIGHLY recommend!!!

Super easy install!
I took extra time to plan where the hole needed to be drilled, but other than that the install went much quicker than I thought it would. It took me about a half hour, being careful sine it was my first time installing it. I had installed an EG4 hybrid solar mini split several weeks ago, this was MUCH faster and easier. I was surprised to see that the indoor and outdoor units were exactly the same between Airspool and EG4. The difference is how Airspool packages their system. Airspool includes everything you need in the box, pre-wired the control wire, included solar cables and isolation box, and the charged lines are already attached to the outdoor unit and the valves are already open so you don’t need to touch them. The quick connectors on the line set were easy to thread on and hand tighten. I liked that it came with an appliance cord already installed, I just had to plug it into an outdoor outlet and it was up and running. Airspool has simplified installing a mini split almost to the level of installing a window air conditioner. Highly recommended!

Customer Service ROCKS
I picked my unit up in Las Vegas due to undeliverable off grid location. After installing I couldn’t get it to power up on A/C power. I sent a message to Airspool about this and that very afternoon I received a call return call. A gentleman named Todd walked me through troubleshooting it which took several calls, on a Sunday even! It ended up being a ground wire. All working awesome now on totally solar power.

Beyond Impressed
I was a little concerned at first at my ability to assemble this. I am an avid DIY-er and I can say with confidence that I stared at the box for a few days before finally opening it to get started. They are not kidding when they say literally five minutes to assemble (actual mounting and everything else might take a little longer) but it really was as easy as mount, uncoil, connect, and plug in.
I already tested the unit and my solar panels haven't arrived yet, but this unit is awesome. Much easier than I expected and the instructions they provided were perfect.

This was one of the easiest things I have ever installed. Everything I needed was in the package. The installation instructions were very easy to follow and the videos made it even easier. I called 2 times before it was purchased with questions and both times was given information beyond my expectations. The unit is working great on AC power and later this month I will be hooking up the solar. Thanks again to Dave and his crew

I am familiar with HVAC but this was a new level, access and info from the supplier was verry encouraging and help full, got my panel from the recommend source and install was as expected, my install was roof mount for the compresser unit it work well, I like the apps that work off the internet and cell phone.

Great option for our yurts/cabins builds.
We were looking for a quick easy way to provide AC/heating for remote cabins and tried out the MS12. for cabins/yurts that did not have power run directly to it, we were able to quickly just move forward with providing cooling to the space without being hindered by the scheduling of the power cabling. The unit provides sufficient cooling during sunny days which is when it is needed the most. this also runs without batteries, which also avoid scheduling limitation when batteries and other power storage/inverter is not available at same schedule. This basically allows us to get the a/c in to keep everyone comfortable. Will definitely, have this in our new builds going forward.

Game changing temperature control with Solar AC
Living in the southern AZ desert with an abundance of sun year round, using a solar heat pump is a no-brainer. We heat the house for a few months in the coolest part of winter and cool the house for a large part of the year withou paying a cent for electricity. Our energy bills have dropped enormously since investing in the first Airspool. With three more now installed in different locations around the property (garage, detached office, and 2 sides of the house), we almost never use the (expensive) central air system in our house anymore and can spend time in the garage working where it was previously unbearable. Highly recommend.

Extremely happy
I'm not a particularlarly handy person and the install was still very easy. The hardest parts were drilling a big hole through the wall, setting a level surface for the condenser (use gravel and a condenser platform), and getting the air handler attached to the bracket (have a 2nd person help you ideally).
Overall the unit performs perfectly fine, and is super quiet. I use it to cool a single small office so 12000 BTU is probably overkill, but it cools down the room in less than 5 minutes. I'm getting power from a non-dedicated circuit outdoor outlet and the AC hasn't tripped any breakers, which was a nice surprise as I fully expected needing to get a dedicated circuit installed.

Easy to install, runs quiet and low power consumption.
We love the new Airspool hybrid unit. It is incredibly cool and runs very quiet compared to our mobile air conditioner - which is louder and uses more power. When the solar is available, virtually no power is used from the grid for hours. Great product and highly recommended.

Truly love it
I've been thinking about installing a solar mini split for 2 years. The only one I was aware of was the one by a company from Texas. After getting high PG&E bills I decided to finally do it. A week before I was about to place my order I saw a video on YouTube about Airspool version. I thought wow another company. And it looks well thought out and includes things that doesn't come with their competitors unit such as the 2.5 inch stucco bit, solar cables and many more. The only thing I needed was the 2.5 inch bit for drywall and OSB board. The directions were the best part. Super clear and complete with visuals. No detail was spared. Much thought was put into the design of this DIY unit. And to my surprise, the unit has built it wifi with an IP address that sits on the cloud so that you can control this unit even when away from home. I was even able to setup a daily schedule to turn on and off while the sun is out. Amazing. I have not used my HVAC since I installed it.
My only mistake installing was that I hit a stud while drilling the 2.5 inch hole 6 inches away from the bracket. My bad. I only looked for a stud where the center bit goes. I shouldve accounted for the entire 2.5 inches.
Overall score: 10 out of 10
Good job Airspool! 👏👏👏

Excellent products, customer service and warranty.
I installed my second Airspool 12K unit last week, obviously I was satisfied with the first. The installation went smoothly and the unit is working as expected.
I selected Airspool for the following reasons:
(1) Their products are well designed with high quality components and are very easy to install. Even the extra items, hole saw, 30 meters of 10 gauge wire, gloves, etc are high quality. The hole saw is multipurpose, masonry, saw that easily cut through my stucco wall.
(2)Their warranty is easily the best available for any DIY mini split.
(3) Customer service is exceptional. I’ve called, texted and emailed them several times over the past six months, they respond quickly and are knowledgeable. When you call, one off the owners answers, usually Dave. Last fall I had a problem with a leaking valve, they sent a technician with a new valve.

Great Quality and Best Customer Service Communication
First, Dave, the owner of the company, is awesome. It is very nice to find someone who is hands on with their company. He will respond to any questions in a very timely manner.
Second, this 12000 btu quick n easy model is exactly as stated. Super easy installation. Very nice unit, just beware, if you turn the temperature down too low, it will freeze you out. Very hot in Fl. already and this unit runs with free solar energy all day long. I have my wife putting her jacket on when I crank it low. Very pleased with my purchase, will be purchasing another soon.

Thank you Dave for the Quick ’n’ EasyTM hybrid mini split 12k BTU after destroying the first one you...
TLDR
Dave is awesome and truly cares about his customers. He is professional and stays in communication with you even after you purchase. I highly recommend buying from him and the unit is great. I had to replace the original one I ordered after kinking the copper lineset. Dave reassured me and made it right by swapping it out for a brand new unit. Thanks Airspool.
I bought the 12k Hybrid Quick ’n’ EasyTM Mini split and had quite the journey of hooking it up. Put the unit in my garage near the ceiling and it was hard to lift and put all the lines through the wall solo at 9 feet high. Eventually I got the indoor unit installed then went outside to connect the lineset to the outdoor unit. Got that hooked up after a little trouble due to the fact that the indoor lineset stub coming through the wall barely protruded out the hole to the exterior brick wall. It was difficult to bend the copper stub lineset down. After connecting these and plugging in the communication cable and power cord I eagerly went inside the garage to test the coolness of the air coming out from the indoor unit. Here is where I made the first mistake of using a a temperature probe. My arm got tired from holding for over a minute and I accidentally pushed the probe too far into the unit. The metal probe hit the fan blower wheel while it was spinning causing a small portion of the wheel’s plastic spokes to break. They fell to the floor but the unit was still working and operating as normal. I blew a sigh of relief and emailed Dave VanZanten, the owner of Airspool. Much to my surprise he responded right away (within 30 minutes). He even sent me a troubleshooting video if I wanted to attempt to fix and a new infrared thermometer free of charge. The indoor unit remained fully operational so I just let it be and counted my blessings.
A few days later I made the decision that I wanted to move the outdoor unit to a new location and mount it to a brick wall that was further away from my home’s central ac unit. After emailing Dave he quickly reassured me that you can indeed move the unit as long as you give it 15-30 minutes of power down time. So I then proceeded to disconnect the lines. Here is when disaster struck. I had to bend the lineset/stubb coming through the wall in a different direction in order to mount the exterior unit in a new location. Trying not to kink this stubb, I still accidentally managed to bend one of the copper lines too far. The result was a leak/kink that let all of the refrigerant out slowly over a few minutes.
I panicked and emailed Dave again late on Easter Sunday. He again responded quickly and professionally. After explaining my mistakes and situation he came up with a plan to send back these units (indoor and outdoor) as long as I could pay for shippping. He even made a new SKU for those like me with thicker interior walls who needed a longer interior lineset stubb. I was able to purchase this new add on and some additional feet of exterior lineset to make the job easier for the new units. Dave sent me a new exterior and interior unit with precharged lineset and prepaid labels to send the old units back. He said he just wanted me to be happy with my purchase even after I totally screwed everything up. I thought I would have to repurchase the entire system at the higher after tariff price but no Dave saved the day. Thank you Dave and Airspool for the quick communication, transparency, and for taking great care of an idiot like me. I definitely recommend getting someone to help you lift and move these units, especially when trying to mount the outdoor unit up in the air on the wall.

Saving me a ton of $$$ on my electricity bill
We needed more cooling in an upstairs bedroom, since we were running our main air conditioner hard all day to keep it cool. With the Airspool hybrid mini split, we save in 2 ways. First, it runs on 3 solar panels for free all day and good efficiency using grid power at night. Second, our main unit now is set to 77 degrees instead of 73 before, and we're actually more comfortable downstairs, too. I recommend Airspool for an easy way to go solar, especially in California where the net metering laws have changed.

Utility Hack: How Solar Tech Should Work
Unlike traditional whole home/grid tied solar, airspool allows solar to work the way it should regarding the value and benefit it provides.
Traditional grid tied roof top solar requires lengthy permits and unless the home was recently built, more often than not a roof replacement/repair and main electrical panel upgrades are required. Airspool does not tie to the grid and avoid these problems. My home needed both a roof and main panel upgrade in order to go traditional rooftop solar so, Airspool allowed me to work around those hurdles and still greatly benefit from solar technology.
The best way to utilize solar technology is to have off grid applications like the Airspool system. That way, you can heat and cool your home while completely bypassing the utility’s expensive and ever increasing prices. I can not say enough about this product and every time I have it on, I smile knowing that it’s saving me a tremendous amount in utility expenses from the very greedy electric utility company. With their ever changing rules on time of use pricing and rapidly growing prices, do yourself a favor and invest in “guilt free” cooling and heating as I like to refer to it.

Great unit especially if you have a large space and time of day billing
I highly recommend Airspool. I installed mine almost 2 year ago and it has made a tremendous difference to both our comfort and energy bill. My house is just under 5000 sq ft and had 4 central air units, with one unit covering the master bedroom suite, including closests, hallways and a bathroom. We installed our Airspool to directly cool our bed rather than wasting money cooling the entire area while we sleep. We are also on a time of use billing plan from NV energy which charges punitive rates for electricity use during the hottest months. Airspools solar allow us to avoid these rates, running the unit on free sunlight. I would definitely purchase again.

I love my mini split!
I got it for the master bedroom because the central air and heat never work well in that room. Now I have the temperature programmed to my liking and I can make adjustment easily (and even remotely). The solar works well - my electric bill is noticeably lower!!

Airspool installed a year ago, and I still love it.
Just over a year ago I bought my Airspool, and it has been used much of the year. We live in sunny Las Vegas, so we used our Airspool in the winter to keep the area a comfortable 70 degrees Fahrenheit. It's now April 2024, and have been running it at 68 degrees turbo all day since it's in the 80's, already.
With the Airspool, my life is more comfortable, and I love it so much. I feel good about using solar panels because I work on being environmentally friendly, and appreciate how much it saves on my summer electric bill.
I highly recommend Airspool.Lower billsRuns on solar

Finally it's possible!! Great customer service
I've been waiting for what seems like 15 years for this tech to mature and come to market in a feasible and legitate product.
If you can drill a hole in your wall, you can install this. I have the tools to do the HVAC tech "required" install, but for the price, this is a no brainer. I had a block wall, old slump block, which required a $45 diamond bit drill, but unless you have this type of block, EVERYTHING is included. Even the whole saw included would probably cut through concrete, just not through my block - it had literal granite in it.
There are competitors on the market. I won't mention them, but you likely are very familiar with them. After reading just a handful of reviews from the other guys, it was an easy call.
In fact, the owner of Airspool, replied to my email, on a weekend, within an hour. I did not expect that, and I even told him to wait until Monday to reply (been a small business owner, so I know what it's like) but he responded to my emails within hours (probably minutes actually.)
I'm only a week or so it, and living in Phoenix, i've got it turned all the way down, but it got too cold (only May.) I'm realistic about my expectations for cooling, so with that in mind, assuming this lasts as long as the warranty would suggest, I expect to be very happy.
Don't hesitate, do it, pull the (metaphorical) trigger!

12,000 BTU unit in Michigan
I installed a 12,000 BTU Airspool unit in a 500 square foot office space in Michigan. It was space that I recently renovated that was using electric wall heaters that were super inefficient.
The install was very easy. The directions had the kind of detail that you want as a DIYer who isn't installing HVAC systems every day. I did install an AC disconnect for the power, but I know these units can be plugged into a normal outlet as well. The unit came precharged with refrigerant, so once I vacuumed out the line sets, I opened the valve that releases the refrigerant and was ready to go! The videos and step by steps online are no joke, it's very easy to install these minisplits.
I think my favorite part about these Airspools is the app. The app allows you to control the head unit from anywhere, which is great for me because my office is outside of my house, so I can turn on the unit when I plan on working out there. The app also allows you to monitor the energy usage of unit, which is a nice feature for anyone who is conscious about their energy costs.
As far as the units performance, I am amazed at how little energy it uses in both heating and cooling functions. With the cold Michigan winters, I am really happy with how the Airspool holds up. And of course, it is great at cooling in the summer too!
I have not yet installed the solar panels to help realize the full potential of this product, but look forward to the savings when I do.
I would definitely recommend these minisplits for anyone looking to comfortably condition a space and save money while they do it.

07The running cost
What it costs to run. Honestly.
50–80%
lower cooling-related electricity costs during sunny months — what Airspool customers typically report
Air conditioning is 50–70% of most summer electricity bills. Solar targets that biggest expense directly.
Some customers report running costs under $50 a year — yours depends on sun, climate, and electricity rates.
No inverter, batteries, or net-metering paperwork — panels plug straight into the unit, so the system around the AC costs nothing.
Run your own numbers: is solar air conditioning worth it?08Straight talk
Is the MS12 right for you?
We'd rather point you at the right unit than sell you the wrong one.
Right for you if…
- One room or zone up to about 500 sq ft — a bedroom, garage, shop, ADU, or addition
- A standard 120V outlet within reach
- Winters that rarely drop below 5°F
- You want solar now, later, or just the option
- You can drill one hole in a wall
Not right for you if…
- Your winters regularly drop below 5°F → HS12 SuperHeat — heats down to −22°F
- You have one big open space closer to 1,000 sq ft → MS24 — twice the capacity (needs 220V)
- You need to condition two or three separate rooms → MU24 / MU36 multi-head systems
- You're renting, or can't drill through a wall → WS12 solar window unit — no hole required

14Everything else
Questions, answered straight.
How loud is the MS12?
The indoor unit operates at library-level quiet and most people forget it is running. The outdoor unit is comparable to a normal conversation. There is no jarring on/off cycling like traditional AC units because the inverter compressor ramps smoothly.
How much space does the MS12 cover?
About 500 sq ft, which is ideal for a large bedroom, living room, studio, garage, workshop, ADU, or guest room. If you need twice the coverage, check out the MS24 for around 1,000 sq ft.
Do I need solar panels right now or can I get them later?
No. The MS12 works perfectly on a standard 15-amp, 120V outlet with no solar required. Add panels whenever you are ready. Many customers start on grid and add solar later.
How many solar panels do I need for the MS12?
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. A little over extends your free-cooling hours.
What happens if I have too much or too little solar power?
No big deal either way. Too little solar means grid power fills in automatically and seamlessly. Too much means the excess voltage simply goes unused with no damage and no problems. The system is designed to be flexible and forgiving.
What kind of electrical outlet does the MS12 need?
A standard 15-amp, 120V household outlet. That is the same outlet you plug a lamp or TV into. The MS12 draws about 8-9 amps, so we recommend not sharing the circuit with other high-draw appliances.
How long does the MS12 take to install?
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. If you have done it before, it can take under an hour.
What tools do I need?
Just a drill. We include a hole saw, drill bits, screwdriver bit, level, gloves, and all mounting hardware. No vacuum pump, no gauges, no torque wrench, and no wire strippers. Just your drill and a free afternoon.
Can I customize my line set length?
Yes. The MS12 comes with a 10-foot pre-charged copper line set, but we can customize it up to 49 feet. Tell us what you need when you order and we will build it at our US headquarters.
Can I move the MS12 after installation?
Yes. The Quick ’n’ EasyTM self-sealing valves unscrew and reconnect without losing refrigerant. Disconnect takes about 5 minutes and reconnecting at a new location takes another 5 minutes. No vacuum pump and no re-charging.
What's the difference between the MS12 and the HS12?
The units are very similar with two main differences. First, the HS12 has EVI SuperHeat technology that heats down to -22°F, while the MS12 heats down to 5°F. Second, the HS12 requires a 20-amp outlet (NEMA 5-20R) instead of the MS12's standard 15-amp outlet. Everything else, including Quick ’n’ EasyTM connection, solar capability, cooling performance, and the guarantee, is effectively the same. If your winters regularly drop below 5°F, go with the HS12.
Will the MS12 work during a power outage?
If the sun is shining, yes. Solar panels will power the unit even when the grid is down. At night during an outage, you would need a battery backup or generator.
What maintenance does the MS12 need?
Very little. Clean the indoor air filter quarterly by sliding it out, rinsing it, and replacing it. Vacuum the indoor coil and spray the outdoor coil annually. That is it.
What's included with my MS12?
Indoor and outdoor units, pre-charged 10-ft twist-to-connect line set, 120V power cord, communication wire, wall bracket, remote control, condensate hose, and our free Quick ’n’ EasyTM Bonus Kit with solar whips, DC isolator, solar wire, hole saw, drill bits, level, gloves, and more. Everything except a drill and solar panels.
How much does shipping cost for the MS12?
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).
