MRCOOL’s DIY series has become the go-to choice for homeowners seeking a cost-effective alternative to expensive A/C installations without sacrificing efficiency or durability in their heating and cooling system. With the latest DIY 5th Generation systems, MRCOOL has enhanced its 4th Generation mini splits by focusing on greater efficiency, eco-friendliness, and cutting-edge technology.
Upgrades of the MRCOOL DIY 5th Generation Mini Splits
1. Industry Leading R-454B Refrigerant
Compared to the 4th Generation mini splits that used R-410a, the MRCOOL 5th Generation mini splits use the R-454B refrigerant. This upgrade makes the newer 5th Generation models more efficient and eco-friendly than their predecessors.
2. Higher Energy Efficiency
Like we alluded to earlier, the MRCOOL 5th Generation mini splits are more efficient than the 4th Generation systems, boasting the highest SEER2 (Seasonal Energy Efficiency Rating) ratings than any other MRCOOL mini split.
3. Covers More Zones
With the new 5th Generation mini splits, MRCOOL is giving users even more flexibility with the option to cover up to 6 zones.
4. Enhanced Controls
The 5th Generation systems feature enhanced controls for an even better user experience. With the Smart HVAC App, you can easily manage your 5th Generation mini split system from your phone and connect with Google Assistant and Amazon Alexa. Additionally, the new MRCOOL DIYPro cable, used by the 5th Generation models, enables more efficient communication for improved performance over previous versions.
5. Quieter Operation
Compared to the 4th Generation systems, the MRCOOL 5th Generation mini splits operate at a lower decibel (dBA) level at both the indoor and outdoor units.
