## Description

Product description

Review: COSTWAY 18,000 BTU Mini Split Air Conditioner, - Bought this in August of 2024. Have used it steadily for 1.5 years now. Cools and heats a 900sqft open shop. It does a good job. I have not had any issues with it what-so ever. Installation was not too hard. The Install direction are just okay - but I managed. My unit is 208-240V. For the cost - it was really a bargain. I would recommend to anyone that is a DIY type person. Having a HVAC tech install it would have really upped the affordability. So far - it has been a good unit. My thanks to the supplier/vendor for the reasonable price and quick shipping.
Review: Recommended -- would buy again. - Works flawlessly, rapidly cools 20'X40' w/12' ceiling bedroom and maintains temp with no problem. I seldom run it below 73F but tested down to 69F. Texas hasn't gotten over a 100F yet this year, but not expecting it to struggle to maintain temp. Well packaged, well reinforced internally to prevent damage -- zero shipping damage -- this is extremely important. Purchased another brand (starts and ends with T) that was very poorly packaged/fell apart and missing parts, worried if it was going to work. Can't hear outside unit when in use, indoor unit could be a little quieter but still very quiet (I'm looking for absolute silence when sleeping). Came with everything you need to install. This is an unsolicited review -- I absolutely hate Vine reviews.

## Questions & Answers

**Q: I will be powering this ac unit with a generator. What are the exact power requirements? Wattage and or amps. Voltage is given 110ac.**
A: According to the description this unit uses 1500 watts. That's 14 amps at 110 AC. While it MAY be possible to run it on a 14 gauge wire, 15 Amp circuit, National Building Code in the United States will require it to be on a 12 gauge wire, 20 Amp circuit. They require that in order to prevent the wire from over heating and possibly starting a fire. BTW, it is recommended that you put it on its own circuit.

**Q: What is the warranty period?**
A: Hello and thank you for your question in regards to the COSTWAY mini spilt ac unit. The warranty is 8 years on parts replacement and 8 years on compressor.

**Q: Could the outside unit be used in a space for a wall through AC?  I understand it needs lots of air circulating.  Is it that unit loud?**
A: It’s whisper quite when I first turned ours on I kept checking to see it was running it’s that quiet

**Q: What  size batterys does the remote use n how many does it take n do they come with it**
A: AAA batteries and yes it does come with batteries.

### ⭐⭐⭐⭐⭐ Costway got 2 out of 3 right and fixed the third!
*by B***N on May 21, 2026*

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.
