“We had a problem with excess humidity in one of our rooms and thought it was a torn duct. We called O'Brien who performs our HVAC Service and within a day, Mike, a service technician came out and do a thorough inspection of our HVAC system.
He discovered an open window in that room covered by interior shutters which we did not notice-it had been open for at least a week during really high temperatures.
He was very kind and understanding even though I felt like a complete idiot (which I was).
There was no charge!
I am staying with O'Brien and will use them when it comes time to replace our system.”

“We really appreciate the service rendered by 2 O'Brian employees: Chris and Delia. They arrived on time, they were professional and polite, they checked everything thoroughly, worked efficiently and fast but without fussing. They explained to us the cause of the leak and removed it quickly without making a mess. Chris even looked into the state of the repaired drain in the crawl space to make sure the floor doesn't need repairs.
We will definitely use the company to solve any problems with plumbing or AC/heating (which we did have as positing experience as this latest servicce). Thank you very much, Chris and Delia!”

“Jordan came today and serviced our unit (it was installed fall of 2025) for the very first time. He was so pleasant and engaging and knowledgeable. We have always been very pleased with everyone from O'Brien Heating and Air. I hope the next time we need any service that Jordan will be sent to help us out! Thanks to this great company and thanks to Jordan!”

“I called for an "installation of an under the sink water filter." The water filter company claims it is a DIY and will probably take no more than one hour . I checked with Chat GBT for the cost to have a professional install this filter and it was $150-$300. I thought it may be worthwhile to have it installed so as to not to bother with doing it myself, so I called OBrien's. When the O'Brien serviceman arrived, the cost was going to be $904.00. Are you kidding me? A surgeon makes between around $211.00 per hour. Your company should be ashamed! You are never to be on my list as a fair and credible organizatio.”

“Rich Rozanski, lead install technician, along with his team, Lucas and Jet, that installed my new HVAC system did an exceptional job! They were thorough and systematic in their process, along with being very professional and courteous throughout the task. Rich worked with Mike Bennett to ensure optimal performance from my unit. Everyone along each step of the process did an incredible job! I would highly recommend your company and especially the team that completed my installation!”

“Rich Rozanski and is team came in here and got the job done . I am a local superintendent for a contracting firm, and I have never experienced such Professionalism.

“We are very pleased with the installation of a mini split unit in our garage. Matt gave a competitive quote, and Eric, Jackson, and Jed did a great job with the installation. They were courteous, efficient, and made sure you were satisfied. Thank you!”

“OBRIEN and service tech RYAN are AMAZING!! Always had great experiences with O’Brien, but this service went ABOVE and BEYOND!! My parents had a crisis of 2 inches of water leaking from a busted hot water tank. When I placed the service call the nice lady on the phone was compassionate and understood the issue. My parents are elderly and needed immediate help. RYAN showed up within 30 minutes!! Not only was he professional, sympathetic, and had a sense or urgency, he had a solution!! Not only were we dealing with the tank crisis but also a potential big purchase issue for my parents on fixed income. But RYAN worked with his supervisor Stacy and they both created a path forward! The new unit was delivered within about an hour. RYAN did an awesome detailed careful job of installing! My parents immediately had hot water again! But this isn’t the end of this story – I am 55 years old and never experienced in my life the customer service, humanity, and compassion that everyone involved displayed. We I said above and beyond, I mean RYAN was on his hands and knees with me wiping up a lot water in the garage. RYAN even was concerned about a big wasp nest at the garage door that I didn’t notice, but he was concerned they would have stung dad. I mean come on – NO other service company would have done above and beyond! OBRIEN thank you!! Stacy THANK YOU for your heart! RYAN a huge THANKS and hugs to you my man!!! I highly recommend them!!!”
