Top MRCOOL FAQs
What makes MRCOOL DIY systems unique?
They use pre-charged line sets, allowing homeowners to install without special HVAC tools or licenses. This saves on labor costs while maintaining factory warranty.
Can I expand my MRCOOL multi-zone system later?
Yes. MRCOOL’s 5th Gen condensers support up to 6 zones, making it easy to add air handlers as your needs grow.
What’s the difference between R-410A and R-454B MRCOOL systems?
R-454B is an updated, lower-GWP refrigerant aligned with new regulations. MRCOOL 5th Gen systems support R-454B and are engineered for higher efficiency and compliance.
Are MRCOOL Hyper Heat systems good for cold climates?
Yes. Hyper Heat models deliver reliable heating performance even when outdoor temperatures drop well below freezing.
What’s the warranty on MRCOOL systems?
Most models include 7-year compressor, 5-year parts, and 1-year remote coverage. Register your product and verify terms for your specific unit.
