Cool Guys did a great job, and while I know the whole world will be in a rush, I appreciate that they took their time to communicate needs, pricing, and then explaining the benefits. Just felt like there was a slightly personal touch...and you don't always get those with the bigger box companies just trying to hit that quota.

Cool Guys is a great company to work with. Chris came the same day I called to give me an estimate on a new AC system. He presented several options, explained them thoroughly along with pricing. Their price was several thousand dollars less than another quote from a different company. The product I chose was installed 4 days later. Chris and his crew did a fantastic job. They are 100% professionals in their field. They have my highest recommendations!
