Best Split-System Air Conditioners of 2026

"I’m extremely pleased with the performance and quality of this mini split. It operates almost silently on 120 volts, and the airflow is impressive. The installation was straightforward after watching a few instructional videos. I appreciated learning new installation skills, and the build quality exceeded my expectations, especially the airtight plumbing. My garage is now a comfortable workspace year-round."

"Installing this system required some tools and research, but I managed it by following online guides. I liked that the unit was easy to connect leak-free and offered flexible installation options, like routing the drain to avoid freezing. The motorized vanes move air efficiently, and overall, it looks neat with the cover kit."

"I spent around $800 total, including accessories and shipping. Although the shipping fee was a bit high for my liking, the system was delivered in two parts and everything arrived safely. The remote works perfectly, but I do wish there was a backup control pad on the unit itself—though that’s a minor suggestion."

"I installed this mini split in my finished basement and after using it for over a month, I’m impressed by its quiet, efficient performance providing both AC and heat. As someone with HVAC experience, I found the installation fairly straightforward, though the instructions could be clearer. If you don’t already own the necessary tools, it might be better to hire a pro. I’d definitely buy this unit again."

"This system works excellently in my Pennsylvania basement—even during the coldest winters. I had it professionally installed and it’s been running without a hitch.

I’m extremely satisfied and would recommend it to anyone."

"I found the installation process to be straightforward and stress-free, especially compared to what professional installers quoted me. The system runs quietly—the indoor unit is barely audible and the outdoor condenser is almost silent. For the price I paid, the value is unbeatable. I had to buy better tape for the line set, but that's a minor detail. After living in Florida and dealing with ductwork issues, this unit has been a true upgrade. If it holds up over the summer, I’ll definitely buy more."

"This mini split has exceeded my expectations in every way. Installation was simple, and the features rival those of higher-priced brands. The only challenge was that the instructions skipped the leak testing step, but online videos helped me figure that out. After two years, it’s still running like new, efficiently providing heat and cool air. I’ve since purchased another unit for my garage, and the experience was just as positive."

"With a background in HVAC, I was impressed by how user-friendly and well-designed this system is. I didn’t need special wiring—just a simple wall plug did the trick. The performance is outstanding, handling both heating and cooling even in extreme temperatures. I did notice a temperature difference between ceiling and bed level, but adjusting the settings solved it. Overall, this system is a fantastic money-saver, and I’m thrilled with how it’s working so far."

"I installed this mini split in my workshop and was pleasantly surprised by how straightforward the setup was—I had everything running the same day. The unit cools my workspace quickly, even when I’m using heavy equipment, and it keeps the temperature consistently comfortable for hours. I’m honestly very happy with its performance in a demanding environment."

"After purchasing two units for our two-story tiny house, I found the setup to be simple, and both worked perfectly from day one. They’re quiet, cool down the rooms rapidly, and I love the convenience of the remote control. The best part is that they were only slightly more expensive than window units, but so much more effective and attractive."

"As a first-time mini split owner, I was impressed by the quality and value of this unit. The customer support team was extremely helpful and quick to respond when I needed assistance.

"The unit arrived quickly and in pristine condition. Installation went off without a hitch. So far, I'm satisfied, though I’ll need more time to truly assess its capabilities and any possible shortcomings."

"I haven’t set it up yet, but I appreciated that it shipped in two packages and included everything needed for installation. The unit also looks really nice—so far, so good!"

"After installing this mini split in my insulated workspace, I've been amazed by how efficiently it cools and heats the area. Even during Michigan's hot summers and freezing winters, the unit keeps my office perfectly comfortable. It's whisper quiet and extremely energy efficient—my electric bill for the barn dropped by half after replacing my old portable AC. The only minor issue is that the room temperature can sometimes be about 5 degrees off from the set point, but I've learned to adjust for that. Overall, the quality for the price is impressive and I'm considering putting more of these in my home."

"I recently added the DELLA Motto Series 12000 BTU Mini Split to my bonus room and have been thoroughly impressed. The unit is a real powerhouse, maintaining a comfortable temperature year-round. My utility bills have noticeably decreased thanks to its high efficiency, and the Wi-Fi and Alexa compatibility make climate control super convenient. Installation was a breeze with the pre-charged refrigerant, and the system runs much quieter than I expected. A great investment for anyone wanting reliable, energy-saving comfort."

"I've purchased two of these units—one has worked flawlessly in my shop, but the second one had issues with the compressor not ramping up. Customer service responded promptly and is sending a new outdoor unit to resolve the problem. Despite this setback, I appreciate their support and hope the replacement will restore the same reliable performance as my first unit."

"Installation was straightforward and I found the unit surprisingly powerful, especially on the heating 'super' setting. The compressor runs quietly—I'd agree with their 29 decibel claim. It's an affordable system with plenty of advanced features, even if I haven't used the WiFi. Just be aware you’ll need a dedicated 20 amp circuit, not a standard wall outlet."

"I noticed lower energy bills almost immediately after installing this. It runs quietly and performs excellently. I would strongly recommend it to others."

"After nearly eight months, this unit has been reliable for both heating and cooling. The price was great compared to similar brands. My only gripe is that cleaning the blower is tough to access—it gets really dusty up there and there isn’t an easy way to clean it out. Still, for the cost and performance, I might buy another."

"Installing this unit was a breeze and it keeps my cabin perfectly cool in summer and warm in winter for a fraction of the cost. I appreciate that it can be hardwired or plugged in, and it works so quietly you barely notice it running. For the price, I’m amazed at the performance and value."

"I chose this brand because it plugs into a regular outlet, making installation much easier. The cooling and heating have both been solid, and the price beats most competitors. Although the remote and app setup took a bit of searching online, overall, I have no regrets and would recommend it."

"After using this mini split through both summer and winter, I can say it’s performed extremely well and kept our utility bills low. The installation was manageable even for a DIYer, and I didn’t even have to turn on our old gas fireplace this winter!"
