Orion is awesome. The technician came to my house right the way and worked very efficiently. Only charged me a service fee. In a hot day like today, can't thank enough for good service and value to bring cool air back in the house!

We've called Orion twice now (at 2 different places ) after our AC went out. Both times they came out on the same day and fixed the issue. Yuri is extremely friendly, knowledgeable, and happy to explain what the issues are. I will definitely call them again next time our AC needs service.

Had a great experience with Orion Air , never thought that it could be so easy to get my air condition work again. Same day appointment , 20 min diagnostics and 20 min repairs, that it, 40 min and my ac is working again. Thank you Guys, from now I'll call only you

They gave me an honest appraisal without charging for unnecessary tests, and did the installation quickly, in the middle of an epic heat wave. They might be newer than some of the other folks around, but they are building a stellar and well-deserved reputation. Don’t hesitate!

Orion HVAC responded to my service request within minutes. They were able to fit me into their schedule right away and were punctual to the job. They were able to locate the problem and fix it in less than 30mins. Punctual, professional, clean and affordable; I will be calling them back for any future HVAC needs!
