EXCELLENT Based on 403 reviews Posted on Christopher KrolTrustindex verifies that the original source of the review is Google. ABSOLUTELY the BEST HVAC company I have ever dealt with. I have replaced multiple systems in the past and I could not have asked for a better experience! Their customer service is superior and they care about the customer. I had an emergency HVAC RTU replacement at one of my businesses and from the time I sent the email requesting a quote, I received a call back within minutes. Tommy their Service manager is one of the best and offered multiple solutions and reached out to his network of dealers to provide the best and most timely option for the replacement with very little to no interruption to the business. He was EXTREMELY knowledgeable as was their entire team. Peggy and Kevin are the owners of the company and they worked diligently, communicated professionally, and ultimately worked me into their already hectic schedule. Both of them communicated personally throughout the entire process to make sure the project was up to my satisfaction. UNBEATABLE customer service!!! Julio and one of his team leaders onsite were extremely professional and knowledgeable. The old unit was removed and the crane operator clearly marked off the area so as to not interrupt customers. On installation day, the crew worked extremely hard, efficiently, kept everything neat/safe, and treated our business with respect. They even stayed afterwards to make sure I understood how to use the new system and answered all my questions. The system has had no issues since installation documenting the quality of their work. We are thankful that we met this company and will absolutely recommend them to our neighbors and fellow business owners. They earned a customer for life.

Stuck with us until he figured out the problemPosted on Ray JohnstonTrustindex verifies that the original source of the review is Google. I had a recent fantastic experience with TopTech . They showed up quickly and right on time, carried out a very thorough evaluation of the problem, and walked me through everything in a way that was easy to understand. What stood out most was their professionalism—no pushy sales tactics, just honest answers and genuine patience in addressing all of my questions. After shopping around, I found their pricing to be better than competitors, and it was clear they weren’t trying to upsell unnecessary work. You can tell the people running this business are fair, honest, and truly care about their customers.
