COSTWAY 12000 BTU Mini Split Air Conditioner, with Heat Pump

This has been the best investment! We have natural gas and this mini split. When temps got to freezing, we ran this and the wall furnace and it kept us warm. This summer has been nice and cool in an old house with very little insulation and old windows. It’s quiet, our electric bill has lowered, and it was easy for my husband to install. Just clean the filter weekly and make sure you keep the outside cleaned up and it’ll run perfect!

Have been using thru summer my area has been very humid what a great test working great and my install of this product was pretty easy if you have some knowledge of electrical and HVAC for vacuuming line set I installed a Mr cool diy 1st which is great also except no line set vacuuming which taught me how to install this item cost was a factor thanks costway

We’ve had these in for about two months. We chose mini splits because the house we bought had outdated baseboard heating and no central AC. Our house is 1200 sq feet and we purchased two of these. (One for the end of the hallway and one for the main living area. They are AWESOME. SO affordable for us as first time homebuyers. The installation wasn’t hard once you get the hang of it. My husband did these with some help. You do have to know your way around wiring and using a hvac vacuum. We are in the North and it’s gotten into the 20’s so far and they’ve done great. The remote doesn’t do much beyond change the temperature it seems. However I should mess with it some more. I’ve barely seen a difference in my electric bill!!!! Which is amazing. Since we have one at the end of the hallway to keep all the rooms warm/cold, I do tend to run a box fan just to keep the air flowing better down the hall. You can’t hear the indoor unit running. We are really happy to have found these. These DO come with “whips” to connect to the disconnect box outside and they do seem decent quality. We already had our own so used those. The drain hose seems flimsy so you may want to use your own pvc pipe. Thanks for reading!

-100 stars. ordered a 2 head unit thru costway, 3 ton system. FIRST unit kept freezing up and showing fault codes. after multiple emails with "tech support" (which takes minimum of 24 hours to get a response of which the response is very vague and gives little to no actual technical information for me to trouble shoot) they decided it was a sensor issue. Sent me new sensors, same issue. Fault codes and no working unit. Then they offered to send me a replacement unit. (after implying the original unit was not installed properly, I've been in HVAC for 42 years, it was 100% installed properly) The new unit arrived with damage so I swapped the parts out with the old unit. New unit ran for approximately 2 weeks until the outdoor temps dropped below freezing. The bottom 4-6" of the condenser does not defrost during the defrost cycle. The ice continues to build on the condenser unit it stops making heat. " tech support" informs me that this is normal operation and I should manually defrost the unit. manual defrost does not defrost the bottom 4-6" of the condenser any more than the normal defrost mode. After sharing the below pics with "tech support", they told me they were going to have a team come to the job location. However, when I asked a time frame for their arrival and if they wanted the unit completely defrosted before they got here, they informed me that the team had to return to their country and offered me $300 as a commercial gesture and told me to keep the unit! I replied that this was far from satisfactory and I wanted a complete refund as well as the $300. I received a reply that they forwarded my request to the proper team and to wait 2 business day for a reply. It has been 7 days with no response, and I've sent a second email request with no response after 2 days.

Bought the 12,000 btu in January for a renovated 460 sq ft garage apartment. It’s May and still going. Be sure and clean the filter frequently. Super quiet. Works like a champ! My a/c guy originally said to get Mr. Cool, but has changed his tune. Now prefers these a lot. Charged us $400 to put it in. We already had the electrical in place because my son’s an electrician. Very affordable home improvement. Simple to operate. We bought two more, one for the 385 sq ft master bedroom, same BTU’s cause it’s the west side of an older home, and a 9,000 BTU for our 160 sq foot music shed. That one arrived without a filter cover. Called Costway customer service. Kathy was friendly even while sick. They sent cover. Took about 10 days. Finally got to turn on the shed’s mini split. Then after a week it wasn’t cooling. A/C guy came and charged the line. May have a leak in the line set. Not sure yet. Should know before too long. They didn’t find one. He said Costway would send another unit if it stops cooling again. It might be in the blower area the a/c man said. Even with the inconvenience, it’s been relatively painless overall considering the cost of the mini splits. Highly recommend.

We were very disappointed in the delivery. There was some sort of mix up and it showed delivered when it was not. When we tried to contact them we could not get any help from the company or Amazon support. It was scheduled to be here on a Friday. Both boxes showed up Saturday evening late... very late. That said, we worked on the install in the evenings during the week and finished it on the morning of July 4th. The install was simple and straight forward. In face, it was easier than I imagined. All totaled, it took about 8 hours. That includes running a new 230volt circuit from the other side of the house. Actual A/C installation, including vacuum time was about 4 hours. The temp outside was approximately 91 degrees when we turned it on. The room temp was near 80 degrees. In less than 1 hour, the room temp was at 70 degrees. This unit cools very quickly. The remote control is very handy since we mounted it relatively high on the wall. The remote allows you to controll all of the functions easily without having to geylt up. The most impressive thing is how quiet this unit runs. It made less noise than our ceiling fan. Waaay quieter than a window unit. It made a huge difference. I give the unit five stars, the ease of installation five stars and the quietness of the unit five stars. However, I am not impressed with the customer service at all so I only gave them four stars. Things you should know: It does not come with a wall mount bracket. For the 12000 BTU, the outside unit only weighs 15 pounds so the small bracket will work fine. The lines come filled with an inert gas that you will release and then you must vacuum down to -1. This will require a vacuum pump and guages but it is easy and quick to do. You will need to install an electrical disconnect next to the unit if it is out of sight of the breaker. This disconnect can be useless or fuseable. I used a fuseable disconnect and 10A fuses as recommended in the manual. *Important* The unit comes recharged with freon. Once you pull the vacuum, you will have to open the valves (requires a number 5 metric Allen wrench) to allow the freon to circulate. *Note* The installation requires an adjustable wrench torque tool. Be sure to purchase one of these before hand to torque the flare fittings. They are not too expensive. The torque was more than I initially thought and I am happy that I purchased the tool. These fittings have to be fairly tight. Overall, the install is easy, the look is clean and they provide the materials to make it look professional. The unit, inside and out, is very quiet. I am not sure about the lifespan but we shall see. Install completed on July 4th 2025.

I was skeptical, being my first mini split I figured I'd try the economic friendly choice and I'm not disappointed! 18k btu runs quietly and nicely. The air smells clean too. It took 30 minutes to cool down my 750 sqft, the liquid line has a little bit of sweat going into the outside unit so I let it cool into the next room. It's seriously pumping the heat out of there too! The unit is quite modern inside and the outdoor has a neat blue fan "like mr cool" If you run into the problem of not holding a vacuum after you pull for about 30 minutes don't worry... Go back over your brass to copper fittings and treat them like you're finishing machine threads with lock washers then proceed with 1/8 to 1/4 turn and you can feel the copper mash "flatter" seating around the brass, then when it begins to resist you are finished. After doing this technique I had a -30 for 30 minutes in isolation "gauges closed" from unit. With everything connected and gauges closed I then unleashed the liquid line "thin" and backed off to the metal rings, no further. It made some whooshing momentarily, after that stopped I unleashed the suction "thick" line, it sounded like a hollow space evacuating. Now it was time to back off my blue line from the gauges connected to the service port. Give it half a turn off and make sure the next turn is a full one, as to not leak too much r32 out. After that you're good to go! Thanks a buch CostWay, highly anticipating the installation of your 18kbtu 19seer

Fantastic...

Excellent product!!

I'm speaking on two units I just installed over the past two weeks so this isn't a full "reliability over time" review. As described, the units arrived in two boxes each (the indoor unit with it's bits in one box and the other bits in the outdoor box). Since the units are economically priced and the performance ratings seem quite good, and I only need heat in the shoulder seasons before I switch to full on wood heat (vs the $$$ electric forced air), they seemed to fit the bill. The heating comment is based on the notes that these will work down to -10C (14F). I don't know if that means the units will cease to work or if they will lose efficiency, time will tell. With all that, I decided to do the install myself. Here is where you learn about vacuum pumps, gauges and oil (another ~$200), electrical cutoffs, codes, etc. Did my research before I ordered and the work involved seemed to be straight forward, including running 12/2 wire and conduit (and a new breaker / etc). Following various install videos and a chat with an HVAC buddy of mine, I quickly determined the best approach and took it, and here's what I learned: - the 2" hole required is going to be a tight fit, so when wrapping with the vinyl, make it tight. If one goes larger than 2", note that the wall cap cover isn't going to fit (as it's 2") and the larger hole will require more filling. - the drain hole in the bottom of the outdoor unit is 25 mm, and if you cannot drain directly out, you will need some extras for it (note the size). I installed my units onto a wood deck so I didn't want the water just running wherever so I did this bit of extra, and here is where you need to know the size, which is in the manual - One has to remove all the plastic protective shipping covering from the indoor head to get the tape off, which has to be done to install the com wire. Make sure to take care when handling afterwards to not mark up the plastic. Once the connections were made, line sets torqued to spec, vacuumed for 15 minutes and vacuum leak checked via gauge, everything in place and electrics connected, only then I opened the valves to release the R32 gas and pressure checked all the fittings again for leaks ( with a 50/50 soapy water solution). Verifying no leaks, time to throw the power. LEDs lit up and with some batteries in the remote, I had the unit pumping out heat within minutes of turning on the main power. The units so far work as planned. The heat stability in the house is better than ever (haven't had to cool with them yet, may update after next summer). They are very quiet, even the outdoor units are near impossible to hear inside, and outside it's mostly a whirring fan sound. Now, why the support comment? One outdoor unit arrived in a damaged box, which I didn't notice until after the delivery guy was long gone. When I opened the box, I noticed that the unit had a considerable dent on the business end (connectors / electrics / control unit). I contacted Costway via the Amazon contact process, complete with explanation and photos of the box and the unit, and in less than 24 hours they had a new outdoor unit on it's way. If I could complain about anything it would be the nearly two weeks to wait for the new unit (same time to get the original one). However as I was not intending to install them right away (and I had one good unit to install currently) and Costway DID CHECK to see if the time to receive it was OK, and it was so I'm not faulting anyone. So far so good, and time will tell. At this stage I'm recommending my friends and family to consider these units as I now know what is involved for the install, and they work well (they are quiet and throws heat, cooling shouldn't be an issue, and reasonable to install with what's provided).

Tres satisfait, rapport qualité prix , et me donne un bon rendement

Very easily installed myself bought 2 24000 and one 12000 these are very good heat pumps

We got this installed in our new house, we have the same units in our apartment rentals and they work well! It says it can heat, but it has to be over 0 degrees in order for the heat to actually work. As for the AC it works perfectly, and we did buy it again! We had to have it installed, so I would plan that ahead and ask for pricing. The unit itself is at a great price!
