So, my HVAC died just when summer began. Who knew, right? I called O'Brien to check it out, and they informed me they could fix it, but at the cost I would pay, installing a new unit would be better and more cost-efficient in the long run, and I agreed. The sales rep arrived on time for our appointment, completed a full measure of my house, and then explained exactly what kind of unit I needed. I was given a choice of three units (due to the limited space in my property, the options were kind of limited - no fault to O'Brien). I chose the unit I wanted, and was scheduled for install two weeks out. This was followed by a pre-install inspection which lasted all of 5 minutes, again, the inspector was on time. Two weeks later, two techs from O'Brien arrived and completed the install in just under 6 hours. They powered up the unit and didn't leave until they were sure everything was working as it should. The next week was the final inspection and was completed without incident. Everyone from O'Brien was punctual, professional, friendly, and overall great to work with. If you need a new HVAC unit or service, I highly recommend O'Brien.” – Alex C.
