“Works wonderful and heats and cools awesome. Just what unneeded for my size home.”
“This is a low cost mini-split is not the easiest to install but very close to it. You will need to vacuum the lines for the best install, We only got the 10k btu unit because we have a small space that needed heating or a/c, but not consistently. Our unit is only 115v, which is great for a simple install. The lineset that comes with the lineset is only 10 ft, which doesn’t give you a lot of length but enough to get outside if you are on an exterior wall. Both the lineset and the electrical lines…”

“Was fairly easy to install after watching a few YouTube videos. Works great. It is fairly silent. It warms our 1000 sq ft garage in a few minutes. I love it and would do it again. So nice having the controlled environment. I also like that I can control it from my phone.”
“Great Mini-Split AC – Perfect for a Hot Texas Concession Stand Bought this to help cool a 500 sq ft concession stand packed with 4 beverage fridges and 3 freezers — and with 100°+ days here in Texas, that’s no small task. Two months in, and I’m very happy with the performance. It keeps the space comfortable and handles the heat load well. Installation was straightforward. I rented a vacuum pump from the local auto parts store to pull a vacuum before charging, and everything else was simple to set.”

Head-to-Head Comparison
Cooling and Heating Capacity
The MEPTY 12000BTU Mini Split offers 12,000 BTUs of cooling and heating power, which is generally suitable for single rooms or spaces up to around 500-600 square feet, depending on insulation and climate. The DELLA Serena 22 SEER2, with its 18,000 BTUs, is designed for larger areas, potentially covering up to 1000 square feet. This makes the DELLA unit a more powerful option for larger living rooms, open-plan areas, or even smaller commercial spaces.
Energy Efficiency and Savings
This is a key area where both units excel, but the DELLA Serena 22 SEER2 takes the lead. The MEPTY 12000BTU Mini Split has a respectable 19 SEER2 rating and claims up to 36% energy savings. In contrast, the DELLA Serena 22 SEER2 boasts an impressive 22 SEER2 rating and promises energy savings of up to 57%. While actual savings will vary based on usage and local energy rates, the higher SEER2 rating and claimed percentage suggest the DELLA unit is fundamentally more efficient. This difference is significant for long-term operational costs.
Smart Technology and Connectivity
The MEPTY 12000BTU Mini Split offers standard convenience features like a remote control and a 24-hour timer. While functional, it lacks advanced smart home integration. The DELLA Serena 22 SEER2, however, is a smart home enthusiast’s dream. With WiFi connectivity, dedicated app control, and compatibility with Alexa and Google Home, it offers remote operation from anywhere. The unique geo-location feature adds an intelligent layer of automation, adjusting settings based on your presence, which is a significant advantage for both convenience and further energy savings.
Noise Levels
Both units are designed for quiet operation. The MEPTY 12000BTU Mini Split operates at a quiet 35dB in mute mode. The DELLA Serena 22 SEER2 goes even further, boasting an ultra-quiet 22 dBa in mute mode. This makes the DELLA unit exceptionally silent, potentially offering a more peaceful environment, especially in bedrooms or studies where even low background noise can be disruptive. The difference between 35dB and 22dB is quite noticeable, with 22dB being closer to the sound of a whisper.
Installation and Included Kit
The MEPTY 12000BTU Mini Split includes a 10-foot line set. This is a standard length but can be restrictive if your desired indoor and outdoor unit placement requires a longer run. The DELLA Serena 22 SEER2 includes a more generous 16.4-foot installation kit, offering greater flexibility in mounting the indoor and outdoor units, which can be crucial for optimal performance and aesthetics. Both units require careful installation, and while some DIY enthusiasts attempt it, professional installation is generally recommended for both to ensure proper setup and maintain warranties. Some customer reviews mention the necessity of vacuuming the lines for optimal installation on both units.
Durability and Advanced Features
The DELLA Serena 22 SEER2 includes features like PureClean tech for improved air quality and an outdoor unit bottom heating element for enhanced winter performance, even down to -15°C. It also comes with a lifetime warranty and is a Red Dot Design Award winner, suggesting a high level of engineering and build quality. The MEPTY 12000BTU Mini Split focuses on core functionality and rapid temperature adjustment, using R32 refrigerant, which is an environmentally friendly choice. While robust, it doesn’t highlight the same level of advanced technical features or extensive warranty coverage as the DELLA unit.
Frequently Asked Questions
Q: Which unit is better for a small bedroom, the MEPTY 12000BTU Mini Split or the DELLA Serena 22 SEER2?
A: For a small bedroom, the MEPTY 12000BTU Mini Split is likely sufficient given its 12,000 BTU capacity and quiet operation (35dB). However, if you desire the absolute quietest operation and potential for smart home integration, the DELLA Serena 22 SEER2 (22 dBa) is exceptionally quiet, though its 18,000 BTU capacity might be overkill and could lead to short cycling if not sized appropriately for the space. For straightforward, quiet cooling in a small room, the MEPTY is a solid choice.
Q: Can I install either of these units myself?
A: While some customer reviews suggest partial DIY installation is possible, both units generally require professional installation for optimal performance, safety, and to maintain warranty coverage. The DELLA Serena 22 SEER2 specifically mandates professional installation. Proper vacuuming of the lineset and handling of refrigerant are critical steps that necessitate specialized tools and knowledge.
Q: Which unit will save me more money on electricity bills in the long run?
A: The DELLA Serena 22 SEER2 is expected to save more money on electricity bills due to its higher 22 SEER2 rating and claimed up to 57% energy savings, compared to the MEPTY 12000BTU Mini Split’s 19 SEER2 rating and up to 36% savings. While the upfront cost of the DELLA unit might be higher, its superior efficiency should result in lower operating costs over time.
Q: I want full smart home integration with voice control. Which unit should I choose?
