Portable AC &

Evaporative Cooler Units from Cool Boss™

Much like the rest of the Cool Boss lineup, the COOLBLAST Series is capable of dropping ambient temperatures by as much as 26°F, and it can do so without relying on chemicals. That being said, the COOLBLAST Series isn’t just about cooling; it’s a feature-rich solution for your convenience. Let time never limit your work. COOLBLAST units feature 4000 lumens of LED floodlights to brighten up your night, and every COOLBLAST model boasts a Bluetooth® audio player for music to accompany your cool, refreshing air.

Every Cool Boss unit includes durable pads, powerful pumps and excelled service that you have come to expect from the team at Hotsy of Tucson. Our store location in Tucson has a large selection of evaporative cooling systems and portable air conditioning units and serve customers all through AZ.


If you’re looking for the perfect space cooler that delivers precise directional cooling, the Cool Boss CB-16 fits the bill. This space-saving evaporative cooler is made for quiet operation and portability, allowing you to use it indoors or out. Oversize 4” caster wheels allow it to easily roll to wherever you need it most. Just hook it up to a standard garden hose or fill the portable water tank, turn it on, and start cooling.

    Very satisfied. I brought in my pest rig for a pump swap to completely different pump system and they were able to make it happen and get my rig back on the road making my business money again. I will reccomend them to my colleagues.
