I could not be more pleased with both the quality of the work and the professionalism of the install team. I had a complete duct replacement and new air conditioning system installed. The crew: Will, Jedd, Nick and Ottavio; were all very pleasant and hard working. The started each day on time, and always cleaned up at the end of the day. This level of service is rare in today’s world, and I greatly appreciate it.
I’ve been an O’Brien customer for over 15 years and have been pleased with them since day one

Dillon Battles, the tech, was very diligent and communicative in his approach to the issues we were having. Took his time to explain everything and did a great job in the overall maintenance of our systems.

Very professional company. From Sales (Chris) to installation (Chris, Cameron, Jet and Mike) to the ladies in the office (Abby and LeeAnn), we couldn’t be more pleased with this company. They went above and beyond to ensure we were well informed through every aspect of installation. We highly recommend and look forward to an ongoing relationship. It’s nice to have a company you can truely depend on from start to finish. Thank you to owner, James Williams. You have a dedicated and loyal team. Strong leadership pays off and you have customers for life!

We recently purchased a new home that needed maintenance on the heating and AC systems. We signed up for an annual review and had our first review done. The technician was prompt and he did the service in a professional and friendly manner. We followed his recommendations and installed a new thermostat while he was here. He had the other parts so all was done in one visit!
