Dan Donnelly HVAC

When we first moved into our new home, we needed to have our HVAC system checked. One of our neighbors recommended Dan Donnelly. We wound up taking a yearly contract with them. They came out to check our air conditioner, and fix an issue with it. Glad we had the service contract. Also, you can no ask for a better group of people to work with, from the office person to the service techs. They are very knowledgeable, friendly and professional. And very prompt in retuning your emails or calls.

During our decades relationship with the company, their service, timeliness, quality of materials, and professionalism is consistently of the highest standard in their field. Brett, Stephanie, and the team are excellent communicators, exceptionally personable, and unquestionably reliable in all they do. If you want dependability, honesty, fairness, and reliability, don't go anywhere else but to Dan Donnelly HVAC. "Service" is meaningful with this stellar team!

I was waiting to write this until the first “winter” gas bill came so I could do a comparison of what we saved by upgrading our system - it was a good chunk! Donnelly HVAC were incredibly professional and did a great job at our house! They installed a new furnace, A/C, whole house humidifier, and filter. Super clean while they worked. Great quality for the equipment. And super nice.

I hired Dan Donnelly to install two central air systems in my duplex, and they did an outstanding job for a very reasonable price. Overall, I found them to be very responsive, super friendly, always on time, and they finish the job ahead of schedule. The results are wonderful.

We have been using DAN donnelly HVAC for almost 40 years. Always excellent service at good price. Had to write review because of last service. Brett & John did an amazing job at our son's Lakewood home. Converted to forced air and added air conditioning. They worked around lots of contractors in & out and kept to a timeline even with challenges. All contractors in house were amazed at the job they did. Thanks so much Brett, John & Steph!!
