Phillip Milligan

I had my AC installed a couple of years ago, and Sean and his team were amazing from the start with a quick and professional installation.
Fast-forward to the heatwaves we’ve been having lately, and my system suddenly started shutting down. I called Sean around 10 AM, and even though they were already busy that day, he was able to stop by within the hour. He quickly diagnosed the issue and had my AC back up and running within an hour.
Sean and his team didn’t just install my AC with exceptional care — the service and support I’ve received long after the installation is what truly sets them apart. That kind of reliability and customer service is hard to find.
If you need anything AC-related, I highly recommend calling Sean and his team. You won’t be disappointed!
Thanks again, Sean!

Let me start this review by saying We are in love with the guys that make up the Sean Patrick Hvac team. I work at a Apartment complex with 160 units. We were on a serious journey to seek out help for our ongoing A/C challenges. We had a few companies come out and give us a quote for service and also new installations. I have to say out of all of them SEAN PATRICK Hvac was always our #1 pick. So now it’s been a few months of working together.

Sean is so nice and helpful. The house never had AC, so his team had to install a new system, new ducting, new furnace etc. He was communicative and fair priced. Highly recommend!

Benjamin Effinger

Sean and his crew replaced our entire HVAC system a year ago (August 2025). The system was running great until a manufacturing flaw in the new outdoor a-C unit failed and leaked all of our coolant. Sean was super responsive, squeezing me into his already booked schedule and repairing the unit at no cost. He is disputing the unit defect with the manufacturer/distributor to get reimbursed for the cost of the lost coolant and pressurization. In addition, he’s advocating for my unit and another one that had the exact same issue to be replaced free of charge. He’s honest, trustworthy, and when he gives you his word he delivers. Cannot recommend his team enough! A++++ Contractor!!!
