I rarely write reviews, but my experience with OSS HVAC absolutely deserves one. I was having trouble with my furnace and heater, so I reached out to OSS on Yelp. Within minutes, I received a personal response from the owner, Alberto, who offered to stop by the same day to diagnose the issue. That level of responsiveness alone is hard to find these days. What stood out immediately was that Alberto is not just the owner—he’s the one who actually comes out and does the work. You can feel the pride he puts into his business from the moment he arrives. He took his time walking me through what he was checking, what the potential issues could be, and the different options I had. No pressure, no upselling—just clear, honest, knowledgeable guidance. When it came to the repair itself, the quality of the work was outstanding. Alberto was extremely thorough, made sure everything was working perfectly before he left, and even took extra time to explain how I could maintain the system to avoid problems in the future. It’s rare to find someone who cares about doing a job right rather than rushing to the next appointment. Their pricing was also very fair, especially given the expertise and care that went into the work. I genuinely felt like I was getting premium service without the inflated HVAC company prices. Overall, my experience with OSS HVAC was exceptional from start to finish. If you’re a homeowner looking for someone honest, skilled, responsive, and trustworthy, I highly recommend OSS HVAC. Alberto has definitely earned a lifelong customer.

Worked with Alberto from OSS HVAC to resolve some issues with had with our heater. He was helpful and helped us identify other items that would need a plumber. Extremely personable and fast, especially around the holiday.
