I had Airflow Service Company install my heating and air conditioning system about 4 years ago. I have used them since then for routine service work, and repairs when necessary. They recently came out to diagnose and repair a malfunctioning starter on my gas furnace, and do some filter work. In my experience, their workers show up on time, and are friendly and polite people. They are tidy, and put booties on over their shoes to keep the house clean. They do good work, and are competitively priced. They also go above and beyond for their customers. When they were installing my furnace, there was an eight week factory backlog on getting the 80% efficient furnace I paid for. Airflow Service Company kicked me up to the 90% efficient furnace at no extra charge, just to keep me from having to wait eight weeks. I really appreciated that!
