Rich Todaro

I can’t say enough good things about this HVAC company, especially Danny. He was truly exceptional and went far above and beyond what I expected. From the moment he arrived, he was professional, knowledgeable, and took the time to clearly explain what was going on and what my options were. Danny didn’t rush the job, made sure everything was done right, and even checked a few extra things to ensure the system was running efficiently. It’s rare to find someone who genuinely cares about the quality of their work and the customer experience, but Danny absolutely does. If you’re looking for an HVAC company you can trust, this is it—and if you get Danny, you’re in great hands. Highly recommend.

I wrote a review in April 2025 describing how extremely please I was with the job that Stevenson did for my family. Now I can address their service after the original sale and installation. This company has quickly responded to all of my questions regarding warranty as well as day to day operation and maintenance of my unit. This matters, this was a big expense and service AFTER the sale is critical to ensure I get the most for my investment. They are a locally owned business with a great reputation. Now I know why. From the office staff to the technicians, just good people. Thank you.

This is the best company ever! We have been very pleased with our furnace and air-conditioning unit that they installed years ago. Whenever we’ve needed something serviced, they have quickly met our need. Art Stephenson, the owner even answered the phone on a Sunday night at 9 PM and listen to our concern about our air conditioner and they were out the very next day and helped us get it serviced and back up and working properly. This is a company that you can depend on. They are very professional and all of the employees go above and beyond to help provide the best customer service possible. We highly recommend giving them a call for any of your furnace or air conditioner needs.
