We had a great experience! The technician arrived on time and was very detailed in his review of our situation (a tree had fallen and knocked our unit in its side). We appreciate being an O’Callaghan customer!

I will NEVER use another company besides you guys again. Yall are absolutely amazing!!! My air conditioning has been not running properly since last summer. It’s been awful. I had another company come out and they did absolutely nothing and charged me so much. I can’t even begin to THANK YOU ENOUGH!!! Your technician Bobby was so polite so professional so informative and is just a great guy!!! I’m so pleased I will be telling everyone to CALL YOU to get the job done right the first time. WOW!! I have air 🙌🏼 Best company by far. And will always get my business!!!
