Let customers speak for us
Went with the Monarch 320. Sleek design and sturdy build. Very happy so far.
We replaced our old grill with the Bull Steer. Compact but powerful. Very happy with it so far.
Energy bills are noticeably lower, and the comfort level is much better compared to our old unit
This is the second MRCOOL we’ve purchased. The 12K fits our office perfectly. Couldn’t be happier.
Cools fast, runs efficiently, but the packaging could be sturdier. Still, highly recommend.
Couldn’t be happier. Keeps our large bedroom perfectly cool, and I love controlling it with my phone.
Perfect system for a nursery. Runs quietly and keeps the temperature steady all night.
Puts out plenty of cold air for our family room. Quiet enough that we can watch movies without distraction.
Picked up the Summerset Sizzler 32". Solid quality, easy to set up, and cooks evenly. Definitely feels like a step up from my old grill.
Bought the Crown 440. Plenty of power and easy to clean. The side burner is a nice touch.
Got the Fire Magic Echelon Diamond 36". It feels like the Ferrari of grills, everything about it is premium. Shipping was on time and well packed.
Perfect for our small apartment. Simple setup, great airflow, and very quiet.
Great system, but I wish the Wi-Fi app was a little more polished. Otherwise, no complaints.
Nice little unit. It’s not as powerful as the larger ones of course, but for a small room, it does the job well.
Ordered the Broil King Baron 420. Website was easy to use and the grill arrived right on time.
