Luis was such a life saver. Our A/C was recycling hot air late at night. Luis responded immediately and even showed up in the middle of the night to fix the problem. Thank you so much!

I can't recommend this HVAC company highly enough. On a Friday night, my AC unit started turning on and off repeatedly. When I went downstairs to shut it off manually, I discovered water leaking all around the unit. I had never used Thumbtack before, but after submitting my request, I received a phone call within 30 seconds. What impressed me immediately was that he was willing to come out on a Friday night. He arrived quickly, was professional, and took the time to thoroughly investigate the issue. This wasn't a simple repair—he performed multiple tests and carefully worked through several possible causes until he identified the root of the problem. Instead of recommending an expensive repair, he found a smart solution and installed an additional component that resolved the issue and saved me a significant amount of money. His knowledge, attention to detail, and troubleshooting skills were truly impressive. Beyond his expertise, he was friendly, honest, and very easy to work with throughout the entire process. It's clear that he genuinely cares about helping his customers and doing the job right. If you're looking for someone who is responsive, thorough, and highly skilled, I would absolutely recommend 56 Heating and Cooling.
