Everyone was communicative and very respectful of my space. They did a great job. I would give them 10 stars if I could!
We needed to have our furnace replaced. We compared estimates from 3 different places. After comparing the reviews, the price, the furnace model, and the warranty, we decided to go with O’Leary Air. We are happy with our choice. Thank you for a job well done!

Our heat pump system had several problems that needed to be fixed : 1. Install new drain pan & new liquid line filter drier. 2. Install a surge protector for outdoor unit 3. Replace the control board that ensures proper defrost operation of the heat pump. 4. Clean and flush pipe that drains the condensate from indoor unit 5. Install condensate trap that can be cleaned They arrived right on time and all of this in about an hour. The work was perfect.

I had an excellent experience with Ashton from O’Leary Air. He was professional, knowledgeable, friendly, and took the time to explain everything clearly while servicing my air conditioner. He was thorough, respectful, and made sure everything was taken care of properly. I also want to give a quick shout-out to Trevor, who was a pleasure to work with as well. Both of these young men represented O’Leary Air extremely well. It’s refreshing to see such professionalism, great communication, and genuine care from a team of polite young men. I would absolutely recommend Ashton, Trevor, and O’Leary Air to anyone needing heating or air conditioning service. Great experience from start to finish!

As usual, an excellent job. Both of the guys who came were extremely nice and professional. I’ve been using O’Leary Air LLC Heating & Cooling since they installed a new HVAC unit about six years ago and it works perfectly. Highly recommend them.

I called this morning around 7:15 AM and Trevor was here to fix my heat pump before 8 o’clock. He knew exactly what the problem was and it was a seamless experience. I am so appreciative.
