Albert Gharbin JR

I've had a couple of job done with advanced air. There response is more than acceptable. Their HVAC tech Herbie is good with repairs and explained the whole process and preventative measure to maintain our system really well. I recommend Herbie Medina highly for all of your service needs.

I had them install a new central air system and they did a great job! Joe was great to work with and stood behind his commitments. The installers were skilled and careful in their work. So far it’s working great. Highly recommended.
