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. Review: Great mini split - 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! ## Features - ️ENERGY STAR&AHRI Certified: Most efficient 2024 Energy Star verified.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.

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! ### ⭐⭐⭐⭐⭐ Recommended -- would buy again. *by S***E on May 19, 2026* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/540756526-costway-18-000-btu-mini-split-air-conditioner-energy-star](https://www.desertcart.is/products/540756526-costway-18-000-btu-mini-split-air-conditioner-energy-star) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-17*
