Our HVAC system was installed (new construction) by a Charlotte area company that has been in business for over 30 years. We have had an annual service agreement with that same company since 2004. Our second floor unit stopped working last night and I called at 7:30AM this morning (Tuesday) to request service. However, I was told they could not send someone out until Saturday. After some research, I then called Tier 1 and was told they would work us in today, but that it might be after 5PM. I completely understood since they did not have any prior service relationship with us. We received a call at 3:20PM that a technician was on the way. Cody arrived promptly and had our system up and running within the hour. He was also very courteous and competent. Excellent service from a company that had no service relationship with us until today. We will be moving our business to Tier 1!
