Trusted Reviews From Your Neighbors!

  • Ethan M. They are a local company who is very responsive to their customers. They communicated with us often throughout the process. We received bids from numerous HVAC companies prior to choosing Bell. Mr. Bell estimated the job and gave us numerous equipment and budget options. He explained the various options and answered all of our questions unlike some of the other companies. After speaking to customers we selected Bell over the other bidders. The installation crew was prompt, neat and professional. All safety / Covid measures were taken.

  • Charles B. I am happy to recommend Bell to anyone. I don’t have a Google Account and don’t want to set up one so I couldn’t complete your request.

  • Manuel & Flor Arbelaez We have used Bell for a long time. They are always are on time and do the repairs for our satisfaction.

  • Peter K. It certainly rang loud and clear when my neighbor had a new air/heat unit installed. Ours was 33 years old and headed for scrap metal heaven. Got a good estimate. The back office and technicians were marvelous. They live by a motto, "Reliability. professionalism, product knowledge and courtesy". Space was tight for a filter. George provided a sleeve for the filter to be inserted easily. Kudos George! Thank you all!

  • Vinny C. Based on 2 phone calls and a diagnostic visit, I highly recommend Bell. Daniel the technician was courteous, knowledgeable, professional, and an advocate for resolving my problems in the most cost efficient manner. I am keeping their number handy.

  • William P. Bell HVAC is a fantastic, green-thinking company that treats customers like family.

  • Jeff R. We have a Geo Thermal HVAC system. Our system crashed during the hottest part of the summer. Chris & Ethan at Bell figured out what the issues where (there were several), made the necessary repairs and even got most of the cost covered through a warranty even though our system was 10 years old and installed by another vendor. Great team, service and repairs.

  • Kain G. Great and prompt service! Technician was fantastic. Pricing was very reasonable.

  • Anthony G. We had a great experience today with the service given by Bell. From the expedited service given by the office staff in particular Flo, to their technician (Stephen) then literally within an hour the plumbers (Chris and Ben), they turned what could have been a disaster into a very, very positive outcome. Our central air system is now functioning as it should. I can not praise them enough for their expert professionalism. We have been with Bell for three years now and will always stay with them. Thank you again to the supervisors and staff of Bell for your devotion and five star service to your customers especially during this pandemic and recent power outage.
