Comfort That Speaks for Itself

See why homeowners and pros alike trust MRCOOL DIY systems to deliver comfort, savings, and easy installation.

Installed a 3-zone MRCOOL DIY in our ranch house — took a weekend and some planning, but it went smoother than expected.

Ryan G., Oklahoma

We upgraded to the MRCOOL Universal central ducted system last year. It’s quieter, more efficient, and runs smoother than our old 4-ton unit. Love that I installed it myself

James H., Alabama

HVAC quotes were outrageous. The MRCOOL Universal let me handle the install myself and saved me about $3,000. It’s been running flawlessly for eight months.

Eric T., Colorado

The Universal outdoor unit is much smaller than my old condenser but somehow does a better job heating and cooling our 2,000-sq-ft home. Couldn’t be happier

Paul F., Virginia

We live in Minnesota, and the MRCOOL Universal kept our home cozy even during sub-zero nights — that heat pump is a beast.

Amanda P., Minnesota

Replaced our outdated 3-ton system with a MRCOOL central ducted heat pump. Took a few evenings after work, but once powered up, it cooled our entire home faster and quieter than expected.
