All reviews for O'Leary Air

Trevor was such a trooper with our four year old shadow asking him all about his work. The service was excellent, timely and well communicated! He caught future repairs/maintenance we’ll need and didn’t upsell on anything. We felt immediately comfortable signing up for their routine maintenance loyalty program.

We had another fantastic experience working with the O'Leary team. From the beginning, their team was responsive, transparent, and professional. They clearly care about their customers and take pride in the quality of their work.

What stood out to us most was their honesty and commitment to delivering what they promised—on time and without any hidden surprises. In a world where it’s hard to know who to trust, they proved to be reliable and ethical, time and time again!

We highly recommend them to anyone looking for a company that values integrity, communication, and customer satisfaction. We and our friends all use them . From our a/c to our tankless water heater we are so happy we have Ol'eary Air to always help us!

Wonderful experience from start to finish with O’Leary Air! Trevor gave an accurate and informative quote, answered all questions and install was the very next day! Blake and Walker were kind, professional, skilled and thoughtful! They were thorough and did an absolutely wonderful job! Great company, great service and great people. Couldn’t ask for more!

Blake and Craig were great throughout the install process. The process was explained up front, all questions answered quickly, and a final walkthrough to make sure operation was understood. They left the garage and outside area cleaner than when they arrived. I would definitely recommend O’Leary Air!

I can’t say enough good things about O’Leary Air, I’ve used them to install furnaces and air-conditioning units in two houses of mine and they’ve done a great job every time. And after five years, and having my first service call, still stellar service! I’m a very happy customer and would recommend that you give them a call!

We had "vent cleaning" done by O'Leary Air. They have this machine that's like a huge vacuum cleaner with a brush on it and they use it to clean all your air vents & returns. They did an excellent job of cleaning and provided photos of the debris that they found in the vents.

Very responsive staff, friendly demeanor, and knowledgeable technician. However, while walking in/out to the condenser he accidently tore my patio shade (photos attached). Generally seems competent, I would just like to see a little more care as they are working.

EDIT: Company followed-up and replaced the screen. Timely and clearly cares about the customer. 5/5.

O’leary air installed our system and were extremely knowledgeable when it came to replacing my old system that died. They did diagnostics first and determined it would be cheaper to replace the unit. O’leary Air came to my rescue within a week of requesting service and installed a new system in time for winter. A few seasons later and we still love our system!

Thank you O’Leary Air fam!

Technician Trevor was very informative, went far and beyond to get the job done. Your company alsi got me a same day appointment! I will be recommending your CO. To people i know! Thank you 😊

All of our experiences have been pleasant! The maintenance performed was done in a timely and efficient manner, no garbage or parts left behind.

Thank you. Great job cleaning all our duct work. Everything was covered and explained in detail. Very clean and efficient. Didn't take very long. Thanks again. ~J

Older Nest unit was replaced with Ecobee. Trevor with O’Leary Air was knowledgeable and great to work with. Fast and efficient.

I left a voicemail at 7pm, and they came the very next day! Fit me into the schedule, troubleshooted the system, and fixed it!
Could not be happier with the service provided by Tanner! Thank you!

Had a different issue arise, and just like last time Tanner showed up and fixed the issue!
O’Leary Air Has now done two service calls to my home in both times they have shown quality work.

5 stars for the technicians that came to the house today, both were very friendly and really knew their job. I highly recommend O'Leary Air for you next home improvement projects.

I definitely recommend them, customer service is amazing, they came really fast and fixed the issue within an hour! Trevor and Ally Thank you so much!

Over some very hot days last weekend, I had a Central Air unit stop working. After calling a number of different HVAC companies, Allison with O'Leary Air was able to get me a same day appointment.

I ended up meeting with Tanner at the residence and he provided excellent service throughout the appointment. Tanner went above and beyond to explain the diagnostics steps, walk me through the required fix (Capacitor Replacement) and further test the performance of the system once it was back up and running.

Tanner also had extensive knowledge of replacement systems and the associated tax benefits/credits available to offset upfront costs if I replace the system in the future. Overall, I was very impressed with the service O'Leary provided from start to finish - they provided a great experience getting my central air unit back up and running.

As a property management company, we work with a wide range of vendors at Profound Properties—and we can confidently say O’Leary Air stands out from the rest. In an industry where reliability and professionalism can be hit or miss, they’ve been consistently responsive, punctual, and fairly priced.

Whether it’s routine service or a full HVAC replacement, they’ve handled every job with care and clear communication. They’ve been respectful to our residents, helpful with our team, and mindful of our owners' needs. That kind of well-rounded service is rare.

We don’t hand out recommendations lightly, but O’Leary Air is one of the very few HVAC companies we trust across our portfolio. They’ve made our jobs easier, and that’s not something we say often. Highly recommend.

Trevor was great! We had a disconnect and reconnect of an A/C unit for pavers to be installed. He was friendly and knowledgeable. I highly recommend this company.

The young man from your company was very thorough and explained how everything works. I was impressed with his respect and kindness. Glad to find a company I can trust.

O’Leary’s staff were professional, competitive costs with several rebates for heat pumps, and installed a quiet system with WiFi controls! Thank you O’Leary team Trevor, Blake and Craig!! I highly recommend O’Leary heating and cooling!!!

Great experience with O'Leary Air installing new heat pump and furnace! They were very professional, knowledgeable, quick to respond and friendly.

Spoke with Kevin on the weekend and he got me an appointment. Trevor came out on Monday to diagnose our old system. He showed the issues with the old AC, explained what options we have with repair or replacement and answered all my questions.

We decided to replace with new heat pump and furnace. Jeremiah and Walker showed up on time, they cleaned the ducts, removed the old system and installed new one in just one day! They were very thorough, did a great job with the install and walked me through the setup after finishing.

Highly recommended, great company and great people!
