I would give Superior HAVAC a 4.5because the service was very good. Our furnace broke on one of the coldest days in the winter and they sent a technician as soon as they were able in the morning after a call to them at 8pm the previous evening. Nick the technicianfrom Superior HVAC was courteous, efficient, professional and provided a clear explanation about what he thoughtthe problems could be and possible solutions. The furnace was about 20 years old so we opted to get a new furnace. Nick spoke to his supervisor to arrange for a new furnace to be installed ASAP on the same day. The furnace was installed during a snow storm but the installers were also very professional and did an excellent job. Fortunately we had heat that evening before another freezing day and another big snow storm.
