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.

I want to take this opportunity to thank you all for such a great job you all did with my recent purchase of a new complete heating and cooling system in my home. I am more than satisfied that I chose Oasis after investigating other companies. I am very pleased with the office personnel who worked on my paper work and billing. I would like to thank Brandy Grinnell my salesperson for sitting down with me and going over all the information related installation and for presenting me with I feel a fair price for the system. I would also like to thank the two installers' Carlos And Daniel for the great job they did, they worked without stopping for breaks or lunch until the job was completed. They were very professional, courteous and very personable,I would hire them anytime. Two other employees had to come back to check the system and they were also of the same quality, Ian and his helper (Dominic)? Two fine young men. So, thank you all for such a great experience which is hard to fine these days Albert and Sally Le Page
