This is the place to go. I was almost swindled by Honest AC. Craig did a great job and got me fixed for 5x less than the other guys. This is the one to pick.

Miko did an excellent job on maintenance of our 2 units. He is very knowledgeable and very thorough in his assessments. His advice and recommendations were very reasonable and appreciated. We would like to maintain continuity with Miko’s service.
