MRCOOL DIY FAQ

Can I buy the equipment from you and install it myself?
Yes. As an authorized dealer, we can help you choose the right configuration and make sure you order the correct components. If you want pro install instead, we can discuss that too.
What information do you need to help size a system?
Room dimensions, ceiling height, insulation quality, window count, and whether it’s a sun-baked room or a shaded one. A simple sketch is often enough to start.
Does multi-zone mean every room can be different temperatures?
That’s the whole point: room-by-room control, so you’re not freezing one end of the house to cool the other. (And yes, it can save money when used intelligently.)
Is the warranty automatic?
Warranty terms are set by MRCOOL and often depend on product registration and compliance with their rules. Many DIY multi-zone systems advertise 7-year compressor and 5-year parts coverage for the original registered owner. :contentReference[oaicite:18]{index=18}
