I had poor indoor air quality and constant dust buildup, so I called for an inspection. They recommended and installed a whole-home air purifier and cleaned the ducts. The difference has been noticeable almost immediately—air feels fresher, and there’s far less dust. Very knowledgeable team and great attention to detail.

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!

I recently had my furnace replaced by Superior HVAC Cambridge and couldn’t be happier with the experience. From the initial consultation to the final installation, the team was professional, knowledgeable, and incredibly efficient. They took the time to explain my options clearly and helped me choose the best system for my home and budget. The installation was completed on time, and they left everything spotless when they finished. My home is already noticeably warmer and more energy efficient. I highly recommend Superior HVAC Cambridge to anyone needing a reliable and stress-free furnace replacement!

I had Superior HVAC Service, Heating & Air Conditioning replace my furnace last week and couldn’t be happier. The quote was fair, and they didn’t try to upsell me on anything I didn’t need. The technicians were skilled and had the job done in just a few hours. My house has never felt warmer!
