Customer Reviews Highlight for 12000BTU Mini Split Air:
One reviewer shared, “I bought this unit to replace a 24,000 BTU unit that had given us years of good service but was icing under use and dripping water on our floor. I decided to replace it rather than chase the R22 pressures and whatever other issues were going on. I bought this 18,000 BTU unit hoping it would be enough to replace the more powerful previous unit. It came quickly and was well packaged. Everything on this unit was well packaged, the directions were clear, and all wiring marked and terminated.” This testimonial indicates a positive initial unboxing and setup experience, with a focus on replacing an older, problematic unit with this newer model.
Another customer noted, “We are diy’ers but not pros and this unit was very easy to install. We bought a vacuum pump for $100 to save the cost of having a pro come and pressure test it. Our temps reached -4 last night and it stayed warm. Came with a couple of dents but the sellers gave us some money off and an extra remote control in case we lost ours as it is the only way to control the unit. Highly recommend.” This review is particularly valuable as it highlights the potential for DIY installation and the unit’s effectiveness in cold weather, even mentioning a positive resolution to minor shipping damage. However, it also points to the necessity of specialized tools like a vacuum pump for a proper DIY setup.

A satisfied customer wrote, “We replaced an old wall mount unit with this one. It looks great and works well. We like it. And, the price is very good.” This review highlights aesthetics, performance, and value for money, suggesting a positive overall experience.
Another user shared their installation experience: “I bought this unit to cool a small warehouse for a home-based business. It replaced a wood stove and large Window AC unit. I did the entire install myself in a few hours. The only item that I outsourced was running the 220 line and wiring in the disconnect switch. Once the power was run the unit was super easy to install. The only special tools needed were a 45* flaring tool and a vacuum pump. The lineset cut and flared really easily with the cutter included with the flaring tool. I deburred the.” This reviewer, like the one for the 12000BTU unit, implies a degree of DIY friendliness for those comfortable with electrical work, and mentions specific tools needed. It’s worth noting the explicit mention of needing a 220V line, which is standard for this BTU range, and professional help for that specific part.
However, a less favorable review stated, “Don’t waste your money or your time with this product. Arrived on time, packaged well. But after install interior wall unit is loud with fan motor making buzzing/humming sound. Now to trouble shoot and wait on parts to fix a ‘new’ unit. Would look at other brands unless you enjoy fixing things you have just purchased.” This is a critical piece of feedback, pointing to a potential issue with noise and quality control for the interior unit, requiring troubleshooting and replacement parts. This contrasts sharply with the “whisper-quiet” claims and highlights a potential risk.
Best for:
The Cooper & Hunter 24 is the go-to choice for those who need serious cooling and heating power for larger areas. This includes owners of spacious open-plan homes, garages converted into living spaces, workshops, commercial storefronts, or any situation where a standard 12,000 BTU unit would be undersized. It’s also an excellent option for colder climates where reliable, robust heating performance in freezing temperatures is essential. If you’re looking for smart connectivity and are prepared for professional installation, this unit offers a high-capacity solution.
Head-to-Head Comparison
When deciding between these two powerful climate control systems, it’s helpful to see how they stack up against each other in key areas.
Cooling and Heating Capacity
This is perhaps the most significant difference. The 12000BTU Mini Split Air is rated for 12,000 BTUs, suitable for spaces up to 750 sq. ft. It provides both cooling and heating, making it a good all-rounder for medium-sized rooms. The Cooper & Hunter 24, on the other hand, boasts a massive 24,000 BTUs. This makes it ideal for much larger areas, such as open-plan living spaces, garages, or commercial areas that the 12000BTU unit simply couldn’t handle effectively. The Cooper & Hunter 24 also offers superior cold-weather heating, capable of functioning down to -13°F, which is a critical advantage for those in very cold regions.
Energy Efficiency (SEER Rating)
Both units feature inverter technology, which is excellent for energy efficiency. The 12000BTU Mini Split Air has a 19 SEER2 rating, while the Cooper & Hunter 24 has an 18.9 SEER rating. The SEER2 rating is a newer standard that’s generally considered more rigorous. While the numbers are very close, the 12000BTU Mini Split Air might have a slight edge in energy efficiency based on the SEER2 rating. However, for the Cooper & Hunter 24, its sheer capacity means it’s delivering that efficiency across a much larger area. For smaller spaces, the 12000BTU unit’s efficiency will translate to lower running costs. For larger spaces, the 24,000 BTU unit is more efficient than using multiple smaller units or other less efficient methods to condition that large area.
Installation and Setup
This is a crucial point of divergence. The 12000BTU Mini Split Air is presented as more amenable to DIY installation, as suggested by customer reviews that mention successful self-installation using a vacuum pump. This can represent a significant cost saving. The Cooper & Hunter 24, however, explicitly states that professional installation is required. It comes with a comprehensive installation kit, which is great for the installer, but it means you’ll need to budget for professional services. This makes the Cooper & Hunter 24 a higher upfront investment in terms of labor. If you’re looking for a more accessible DIY project, the 12000BTU unit is the clearer choice. For those who prefer to outsource installation entirely and ensure it’s done by a pro, either unit can work, but the Cooper & Hunter 24 is geared towards that.
Smart Features and Connectivity
The Cooper & Hunter 24 stands out with its included Smart Kit, enabling smartphone control via an app. This offers modern convenience for remote operation, scheduling, and adjustments. The 12000BTU Mini Split Air also offers smart features like a 24-hour timer, Sleep Mode, and Eco Mode, which enhance usability and efficiency, but it doesn’t appear to have the same level of Wi-Fi connectivity and app integration as the Cooper & Hunter 24. For those who prioritize smart home integration and remote control, the Cooper & Hunter 24 has a distinct advantage.
Refrigerant and Environmental Impact
The 12000BTU Mini Split Air clearly states it uses R32 refrigerant. R32 is generally considered an improvement over older refrigerants like R410A because it has a lower global warming potential and is more energy-efficient. The Cooper & Hunter 24 is pre-charged, but the specific refrigerant type isn’t explicitly mentioned in its primary description. It’s highly likely to be R410A, which is still common but less environmentally friendly than R32. For eco-conscious buyers, the 12000BTU Mini Split Air has a slight edge here.
Noise Levels
Both units are described as operating quietly. The 12000BTU Mini Split Air specifically highlights “whisper-quiet operation,” which is a significant benefit for noise-sensitive environments like bedrooms. The Cooper & Hunter 24 also mentions “quiet operation.” However, one negative review for the Cooper & Hunter 24 cited a loud interior unit with a buzzing/humming sound, which could indicate a less consistent experience regarding noise compared to the 12000BTU unit, at least based on that specific feedback.
Value and Price Point (Implied)
While exact prices fluctuate on Amazon, generally, a 24,000 BTU unit will be more expensive than a 12,000 BTU unit, both in terms of the unit itself and the installation costs if professional installation is mandatory. The 12000BTU Mini Split Air, with its potential for DIY installation, offers a strong value proposition for its capacity and features in smaller spaces. The Cooper & Hunter 24 represents a higher investment but delivers significantly more power and features, making it valuable for larger or more demanding applications where its capacity is essential.
