The EasyPro® sits between the two. It has a higher SEER2 (20.2) and better warranty (5-yr compressor / 3-yr parts) than the DIY Select, but a shorter warranty and lower SEER2 than the premium DIY 5th Gen (which offers 7-yr compressor and Energy Star certification). It’s the best value for buyers who want more than entry-level without paying full premium price. Does it need special wiring? No — the EasyPro® 9K runs on standard 115V household power. No 230V wiring or electrical panel upgrade required, though a dedicated 20A circuit is recommended. What is the minimum cooling temperature? The EasyPro® cools down to 5°F outdoor temperature. For heating, it operates down to -13°F. If you need cooling in extreme cold climates, consider the DIY 5th Gen instead. Is it Wi-Fi compatible? Yes. Control your system from anywhere using the MRCOOL Smart HVAC Controller® app on iOS or Android. It also works with Amazon Alexa and Google Assistant for hands-free voice control. What is the warranty? The EasyPro® is backed by: 5-Year Compressor Warranty 3-Year Parts Warranty Recommended BTU By Room Size BTU Capacity Recommended Room Size (Sq.
