Frequently Asked Questions
What's the difference between the 5th Gen and 4th Gen?
The 5th Gen MRCOOL DIY® is a significant upgrade with three key improvements: it uses the next-gen R-454B refrigerant (more eco-friendly with lower global warming potential), delivers higher energy efficiency with improved SEER2 ratings, and features enhanced components for better overall reliability and performance.
Can I install it myself, or do I need a professional?
Yes — that's the beauty of the MRCOOL DIY® system. No HVAC tools or certification required. You connect the indoor and outdoor units yourself using the pre-charged QuickConnect® line set. The only professional you'll need is a licensed electrician for the electrical hookup to ensure safety and code compliance.
Does it work in cold weather?
Absolutely. The 5th Gen features low-ambient heating technology and delivers reliable heat even when outdoor temperatures drop to around 5°F — perfect for year-round use.
Does it heat as well as cool?
Yes. All 5th Gen models are full heat pumps, providing both heating and cooling for true year-round comfort in a single system.
Is it Wi-Fi compatible?
Yes. Control your system from anywhere using the MRCOOL SmartHVAC app. It also works with Amazon Alexa and Google Assistant for hands-free voice control.
What is the warranty?
Your purchase is backed by MRCOOL's industry-leading warranty:
- 7-Year Compressor Warranty — replacement coverage if the compressor fails within 7 years
- 5-Year Parts Warranty — full parts coverage for 5 years from date of purchase
