“Andrew and his crew did a great job installing our central air system. They were able to give us exactly what we wanted for a great price. We had Andrew pull permits for the job and he did it in a timely fashion and handled all the scheduling with the town. Andrew also gave us a great price. Would definitely recommend Active Air for all your heating/cooling projects big or small.”
— Hagen George“Highly recommend Active Air! Andrew responded right away to my inquiry and they came out quickly to fix the problem.
They were very professional and explained everything that was going on and what needed to be done. It’s hard to find companies that are both knowledgeable and genuinely helpful, but they exceeded expectations. Highly recommend this company for fast, honest, and reliable service! Will definitely use them again, if needed!”
— Jodi“Our new HVAC system from Active Air was an excellent investment, thanks to their exceptional service. Andrew's expertise truly stands out; he's knowledgeable, meticulous, and ensures superior quality. Exactly one year after installation, he proactively contacted us for our annual maintenance, just as promised. He didn't just show up; he sent a detailed plan beforehand and then provided a thorough explanation during the appointment. Active Air earns my highest recommendation for their trustworthiness and commitment to customer satisfaction.”
