I moved into my home in Spring of 2020, and I was told that I would be due for my first HVAC check up in Sept of that year. By the time September rolled around, I had long forgotten, but Danny called me, and stayed on top of making sure things get scheduled timely. The tech that came out was wonderful & I have no complaints whatsoever. Check-up #2 just rolled around, and on-the-spot, Danny called to get me scheduled. The same tech came out for routine maintenance for my furnace, and he was just as friendly and thorough as last year. So far, so good!

Our pilot light wouldn't stay lit and we had another local company come out to troubleshoot and said we need a new furnace that would run $5,500. We called Sterling for a second opinion. The technician was extremely knowledgeable and showed us the blower motor was just clogged and dirty, he cleaned it and it was good as new. That's just the type of people they are, they don't try to upsell you or try to sell you something you don't really need. Truly honest and professional. Definitely will never use anybody else! STERLING FOR LIFE!

After calling at least 5 local HVAC professionals in the area, Sterling genuinely outperformed my expectations on price, quality of work and speed. Paul, Tim, Jordan and Mike worked diligently to listen to my needs, my budget, and my expectations. I went with the Bosch unit and it must be the most quiet, yet powerful system I have ever witnessed. I got several estimates and really did my homework.

I was amazed at the price of the unit compared to much more inferior equipment. I feel these guys are honest and genuinely do their best to make you happy. I now know much more about HVAC and feel I have a proficient working knowledge of the brands and their capabilities. I am hopeful their ongoing service will keep me this satisfied. Thanks Guys! Mark

Sterling Heating & Air Conditioning has been a great company to work with. They provided competitive pricing on a new equipment install, did great work, and have been very responsive to any questions I had. If you are thinking about HVAC work, definitely consider them you will not regret!
