" I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"Prior to hiring Topshelf to install a wholehouse steam humidifier I spoke with several companies. Darrell responded quickly, was knowledgeable and willing to explain and answer all my questions and concerns. His team arrived on time, introduced themselves, followed Covid safety measures, put shoe coverings on everytime they entered my house. When the installation was completed, they made sure I knew how to operate the system. No trace of them was left behind only a house that now is humidified and overall much warmer with a lower temperature setting. I would highly recommend this company!"
