We had an issue with poor airflow and uneven temperatures throughout our home, so we contacted Superior HVAC Cambridge for ductwork repair. They identified leaks in the ducts and sealed everything properly. The improvement was immediate — every room now feels comfortable. The team was punctual, professional, and very tidy. Highly recommend Superior HVAC Cambridge for any airflow or duct issues!

Superior HVAC was awesome start to finish. They replaced our 20 year old furnace with their new product. Ryan was professional and left the work place very clean! I highly recommend!
