Frequently Asked Questions

What does MRCOOL make and why does it show up in off-grid catalogs?

MRCOOL makes mini split heat pump air conditioning systems known for their DIY friendly precharged line sets, which let homeowners install a heating and cooling system without needing an HVAC tech to evacuate and charge the refrigerant lines. They show up in off-grid and solar catalogs because mini splits are dramatically more efficient than central AC, which makes them realistic to run on solar plus battery setups.

How does a MRCOOL mini split compare to a traditional central AC or window unit?

Central AC requires ductwork and uses significantly more electricity per BTU of cooling. Window units are cheap but inefficient and only cool one room. A MRCOOL mini split runs at 16 to 22 SEER efficiency (versus 14 to 16 SEER for typical central AC), cools individual zones independently, and uses far less power per hour of operation, which makes it the right pick for solar powered or off-grid homes where every watt counts.

What size MRCOOL mini split do I need for my space?

As a rough guide, plan on around 20 to 30 BTU per square foot of conditioned space, with adjustments for ceiling height, insulation, and climate. A 12,000 BTU unit cools roughly 400 to 600 square feet, while a 36,000 BTU multi zone unit can handle a small home. Always check the manufacturer's sizing guide for your specific climate and home.

Can I actually install a MRCOOL mini split myself?

The DIY line set design genuinely removes the most technically demanding step (refrigerant handling) from the install. A confident DIYer with basic electrical experience can install a MRCOOL DIY series mini split in a weekend with standard tools. The electrical connection to your panel should still be done by a licensed electrician unless you're comfortable with that work. For non DIY series MRCOOL units, professional HVAC installation is required.

Can a MRCOOL mini split actually run on a solar powered home backup system?

Yes, but sizing matters. A 12,000 BTU mini split typically draws around 700 to 1,200 watts while running, which means a 3,000 watt or larger battery inverter can run it without issue. For 24/7 solar powered operation, plan on enough solar capacity to cover the daytime usage and enough battery storage to cover the nighttime usage. We can help size a solar plus mini split setup if that's your goal.
