After a terrible experience with another A/C company, their knowledgeable, gimmick-free approach was a breath of fresh air. No "spin the wheel" tactics--just a real conversation. I sent their General Manager, Jim, the estimate I'd received from the other guys and a separate second opinion along with my concerns. Instead of speculating, Jim sent James out to evaluate our system personally. James spent two hours inspecting everything and discovered the previous company had recommended a massive amount of unnecessary equipment and failed to mention that the actual issues were caused by their own poor installation. The best part? Cool Willy's didn't charge us a dime for the visit, calling it a "re-evaluation." The next day, they sent an estimate for the actual repairs that was less than half the price of the original quote. It's rare to find this level of integrity.

They are not only available by phone on weekends, but will do emergency repairs then, which I needed recently. Being on a maintenance contract with them is the best investment a homeowner can make.
