What Our Clients Say

A woman enjoying her AC - O'Leary Air in Hillsboro, OR

Katie C.

Bought a home that had an air pump installed by O’Leary Air the year prior. I found there was a whirring noise and called Kevin to see if he could check it out. Kevin made it out to my house to quickly troubleshoot the issue. He was thorough in determining what the source of the noise was and then fixed it without charging me for the ...

Rick W.

Kevin was quick to answer my after-hours voicemail, asked for a brief description of the problem, and showed up on time ready to address the issue. He worked through his steps to diagnose the problem and had it figured out in about 10 mins, and repaired in about 20. All this is for what I consider a very reasonable price. When I have future HVAC needs ...

Richard W.

Kevin was phenomenal. I was looking for someone local to assist with a refrigerant leak and found Kevin. Boy am I glad I did. Kevin responded immediately to my call and set up an appointment for the next day. He arrived on time and helped find the leak. He even took care of all the warranty work on my unit to get a new part. I ...

Our HVAC was down and Kevin responded with a service call the next day. He fixed the problem quickly. Thanks again, Kevin.

Kevin is solid. I have had to use him for a couple of things and he is on time, professional, funny, and gets the job done. I give him 5 stars and highly recommend to anyone in his service area.

Kevin and his crew are simply the best. They know their stuff, are kind, and professional. Would recommend them to anyone. We appreciate you!

Kelsey R.

Kevin absolutely saved the day- our AC stopped working during the heatwave. I contacted him on Friday and he was able to get to us on Monday afternoon! Was friendly, and was in and out in maybe 5 minutes. Could not be happier! Thank you! 🙂

Skippy N.

Hottest day of the year my Air conditioning Unit went on the fritz. Kevin was here the next day (July 29th) and fixed it in 15 minutes! Extremely kind, professional, and courteous. I will always call O’leary Air from now on!!

Casey H.

Kevin came out to do an emergency repair of some very poor work that had been done by another service. He was willing to jump in and take over where the other service was stuck and told me I needed a complete replacement of a 6 year old system. Kevin quickly and accurately diagnosed and fixed the problem saving me thousands of $. Highly recommend you ...

Hugo S.

I called Kevin @ O’Leary Air on a Tuesday regarding a last-minute repair that needed to be done at one of the properties that we were purchasing. Kevin was very responsive and immediately scheduled a walkthrough and service installation for the following Tuesday and Wednesday. He was very responsive and cognizant of the deadlines associated with our real estate transaction. His prices are competitive and fair. ...

Alexander O.

Kevin is awesome to work with! Great communication, he let me know what was going on and he would text too which is my preferred method for communicating. Thank you, Kevin! Got my house cooling again!!!

Armen P.

This is 2nd time we have used Kevin and O’Leary Air. First time was to repair a water heater and this time they installed a new furnace. Would highly recommend. They had the best price and fastest turn around. He diagnosed the problem yesterday afternoon. By 3pm today we had a new furnace installed. Great service, great prices, knowledgeable and friendly. 5 stars all the way.
