Homer S. (Wilmington, 28405)
"O'Brien Service Company installed a new HVAC system in our condo. It was a great experience from the sale to the installation. Mike R., our design specialist, did an outstanding job of explaining our options and helping us make the choice that was best for us. He continued to be easily accessible throughout the entire process. The installation went smoothly and was completed in a timely manner. Chris, our lead installation technician, did a great job wrapping up the installation by explaining the proper use of the thermostat and our new system. He also answered any questions that we had. We are very pleased and highly recommend O'Brien Service Company." - Homer S. (Wilmington, 28405)
Jerry J. (Leland, 28451)
"O'Brien Service Co. has replaced and installed two Trane HVAC units (3 zones) for us. They did an excellent job, both times (2018 and 2021). Matt C. was a pleasure to deal with. He explained our options and answered our many questions and even helped us with the Trane app set up. Wish we could remember the names of the installation crew but I'm sure you have them on record. They were all great - respectful, polite, professional, and punctual! I highly recommend O'Brien Service Co." - Jerry J. (Leland, 28451)
