Comfort That Speaks for Itself

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

Each of our three MRCOOL air handlers runs perfectly quiet, and it’s awesome being able to control them separately. Installation videos made the whole process doable

Cindy M., Texas

I installed my MRCOOL Universal nearly two years ago. It’s been maintenance-free, super efficient, and I love how consistent the airflow is through my existing ducts

Dave K., Georgia

Our double-wide doesn’t have room for a big air handler, so the MRCOOL wall unit was perfect. Easy install, clean look, and it cools like a champ

Amy R., Florida

The quotes for replacing our old packaged unit were crazy. Installed a MRCOOL 18K system instead — now the living room and bedrooms stay cool all summer without breaking the bank.

Dean L., Alabama

You’d never know it’s running — it’s that quiet. The unit heats our entire single-wide better than the old furnace ever did.

Brenda C., Oklahoma

The MRCOOL mini-split doesn’t take up much space, which is perfect for our tight hallway. It cools faster than I expected and doesn’t trip the breaker like our old window unit.
