*by A***. on June 2, 2025*

As an HVAC installer and service technician since 2018, I've seen my share of equipment. That's why I'm so impressed with the Rovsun 28K BTU 3-zone mini-split – it's a stellar performer backed by outstanding customer service.First and foremost, Rovsun's customer support is truly top-tier. I've installed multiple units, and when I needed assistance with one, their team responded to my email inquiry the very next business day with an immediate resolution. This level of proactive and effective support is critical in the HVAC world, where issues can arise regardless of brand. Rovsun's commitment to standing by their product is a significant factor in my strong recommendation.The mini-split unit itself is built to last. Its construction quality is on par with, or even surpasses, many higher-priced options. Installation is straightforward, and the system comes together seamlessly. Key features like the user-friendly remote with large buttons and an intuitive, well-lit LCD screen enhance the user experience. Operation is remarkably quiet, and the high fan speed provides excellent airflow. For extreme needs, the "super" mode offers extra power.

### ⭐⭐⭐⭐⭐ Great Unit 1 Year After Install
*by M***T on May 17, 2025*

Great unit, easy install. You can hire a HVAC company to come pull a vacuum or order a vacuum pump and gages here on Amazon for $100-$150. Unit is precharged and you only have to pull vacuum on the line sets and head units. I've had this unit installed and running for a year now. The heat works great all the way to 6 degrees Fahrenheit out doors. Cooling works great even on 100+ degrees days.the unit is also very efficient as my power bill over all has averaged $40 less each month since install.

### ⭐⭐⭐⭐⭐ Excellent customer support!
*by J***T on June 20, 2025*

Why did you pick this product vs others?:I bought the dual zone 27000btu 18000x18000 unit and an extra 25ft line set. Installation was very easy since I do have a lot of construction and hvac experience. Della provided almost everything I needed, short of the vacuum pump, gauges, and gas. I ran into one small problem common to these dual zone units. I called the Della customer service number on the back of the included manual. A nice, well spoken, young lady answered, took my info and told me that technical support would be calling very soon. Within 10 minutes another nice, we'll spoken, young lady talked with me, and solved my problem within 2 minutes.The unit is cooling and working as advertised now. Thank you Della for providing such prompt, awesome customer support.
