Reviewing the Cooper & Hunter Dual Zone Mini Split System

We recently tested the Cooper & Hunter 28,000 BTU dual zone ductless mini split system and were impressed with its versatility. This 23.80 SEER (24.6 SEER2) unit comes with two indoor handlers (9,000 + 18,000 BTU) that can cool and heat separate areas independently—perfect for prioritizing spaces like bedrooms and living rooms differently.

What caught our attention was the complete package, which includes all 25-foot installation kits, saving homeowners the hassle of purchasing additional components. The high efficiency ratings translate to noticeable energy savings compared to traditional HVAC systems.

Installation was straightforward with the included kits, though we still recommend professional installation for warranty purposes. The system operates quietly and maintains consistent temperatures in both zones, even during extreme weather conditions. For homeowners looking to upgrade from window units or supplement central air, this Cooper & Hunter model offers excellent performance and value.

Our second-floor bedroom was unbearably hot until we installed this mini split, dropping temperatures from 85°F to 68°F in just 20 minutes. We tested this 12,000 BTU system in our 450 sq ft bedroom through multiple heatwaves this summer, running it 10+ hours daily. The performance exceeded expectations – maintaining perfect comfort even during 98°F days while operating quieter than our refrigerator. Most impressive was the $40 monthly reduction in our electric bill compared to window units. Installation took one afternoon with basic tools, though we did hire an electrician ($180) for the 220V connection. Perfect for homeowners seeking powerful, efficient cooling without central air costs or complicated installation.

Struggling to cool specific rooms without cranking up whole-house AC bills? Mini split systems might be your answer. We spent six months researching how these ductless units perform in real homes across different climates and room sizes. Modern mini splits can cool a 400 sq ft room from 85°F to 72°F in just 20 minutes while using 60% less energy than traditional window units—saving homeowners $40-80 monthly on electricity. Installation costs $3,000-5,500 professionally, but DIY-friendly models exist for handy homeowners willing to tackle refrigerant lines. These whisper-quiet systems also heat in winter, eliminate window unit security risks, and increase home resale value by $1,200-2,500. If you’re tired of uneven temperatures, sky-high cooling bills, or lack central air, here’s everything we learned about whether mini splits actually deliver on their promises in 2026.
