Overall, I had a good experience. The repair turned out to be much more complicated than anyone expected, and in the end my air conditioner needed to be replaced rather than repaired. While it was frustrating to be without A/C during an extreme heat wave, the team was responsive, kept me informed, and worked to get everything resolved. The new unit is working great, and I'm very happy with the final result. I appreciate their professionalism and would recommend them.

We had persistent humidity and mold issues in our bathrooms and the team assessed the whole ventilation system. They upgraded the exhaust fans and tied them into proper exterior venting. the moisture problem is completely gone

Excellent service from start to finish. The team was professional, punctual, and completed the air conditioning installation quickly and efficiently. They took the time to explain everything clearly, kept the work area clean, and made sure the system was working perfectly before leaving. Very friendly and easy to deal with. I’m very satisfied with the overall experience and would definitely recommend them to anyone looking for reliable HVAC service.

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.
