"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan! "

"AirStars Corp was absolutely amazing! They were very professional and really knew what they were doing. They changed the insulation and fixed the pipes, which had been connected wrong before and were starting to leak. Any other company would probably have told me to replace the whole system, but AirStars took the time to do things right. You can tell they care about quality and their customers. I’m so impressed with their work, highly recommend them! "
