"I just bought a house and the AC unit and furnace were the originals from 1983 and inoperable. I requested a few quotes and Bill came out from Cool Air the next day. He was very friendly and knowledgeable and provided the most detailed quote. I chose Cool Air because I felt like I knew exactly what I was paying for and would not be surprised with additional costs. I also mentioned wanting a smart thermostat and he made a recommendation. They scheduled me right away and the installation went seamlessly and they even installed my smart thermostat. Bill came by afterwards to walk me through proper maintenance and warranty information. Overall professional service and I was very happy."

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."
