Farah Pierce8 June 2026
I had AC issues and I called Northstar. The guy who came was friendly he checked the unit and said there’s something wrong and j repairing it would cost over $3000, but best would be to replace the unit which would be over $12,000.
For my own satisfaction I called another company they came in they check the system and were able to fix the AC for a few hundred dollars. Please do not work with this company they are liars. I’m sorry if someone believed them and spent thousands of dollars replacing the unit which probably wasn’t needed. -

Charles arrived early. Was very knowledgeable and did a great job diagnosing the problem, and fixing it. He also gave advice on preventing this and other problems.

Tech Andrew Ramos was pleasant, professional and able to fix the issue with my water heater. I recommend him to anyone.
