Our Happy Clients

Testimonials

I had a fantastic experience with Sean Patrick HVAC! I reached out for an estimate and Sean was able to come out later that same day; he was friendly and gave a thorough breakdown of our options. The entire AC unit needed to be replaced and with all the current heatwaves I was worried we would be without relief for a while, but the Sean Patrick team had it done within a couple of days. All the technicians were extremely friendly, knowable, and kept a very clean workspace. Joseph and Sean were excellent with overall communication, which was very important to me. I would use their services again and highly recommend them to anyone!

I contacted Sean for an a/c estimate and I texted a pic of my old unit. He very quickly sent me a quote. We set a date for immediate installation. His team arrived on time and did a great job. They were professional and work very diligently. I would definitely recommend.

I had gotten quotes from four different companies prior to this. Both Sean and Joe Are very professional. Neither one of them wants to haggle with you and will give you the best deal they can. They told me what products are good what products are mediocre and what I can get for my money. They also set up the time their workers showed up, removed my old air-conditioning system, and Placed a a system within five hours. Fantastic I would highly recommend these gentlemen. They were also willing to work with third-party products, but did not recommend it as the warranty would not be as good, but they gave me as good as a price As I would’ve gotten on a direct sale.Highly recommend this company.

Improved air quality in your home or business!
