Best Energy Rebates in Austin TX

So incredibly disappointed. I paid $100 for a diagnostic to be told that I need to get my whole ac unit replaced. I was told my free-on was basically empty and that it would cost me $2,000 to refill it. They recommended that I instead replace the whole unit.... I trusted that they were truthful when mentioning my free-on was low and almost moved forward with replacing the entire unit for $10,000...Luckily, my friend sent me the contact information for another repair man. I called them up and they came by and checked my free-on levels. They said my free-on levels were normal and laughed when I told them I was previously told my free-on was empty. He proceeded to show me the free-on meter and I could see that it was in fact not empty....They said my motor needed to be replaced and that I could still get a few more years from my unit. It cost me $400 to change the motor....And yes, after getting the motor replaced, my ac has been working perfectly FINE. It's going strong and clearly has no issues with the free-on.I wouldn't trust this place. They are very salesy and will immediately tell you that you need a new ac unit when there could be another solution. Apparently they will also just blatantly lie about your free-on levels and god knows what else. I'm just annoyed I paid a $100 diagnostic fee to get lied too. Thankfully, I didn't spend thousands of dollars on a new unit and only had to spend a few hundred. It's frustrating that my ac issue could have been fixed faster if they didn't lie. This weather without ac is brutal...
