My A/C went out but it is under warranty with the manufacturer. Ace came out and wanted to sell me a new unit and were very very persistent that it would really be the only good way to fix this. Since warranty covers the compressor and fan controller, I would only need to come up with the 2000 dollars to cover the labor and refrigerant. 2 months later it is broken again. The same tech came out and again tried to sell me a new unit since mine is after all 8 years old. I told him no and he told me it was the expansion valve which is also covered under warranty. But,, I would need to pay for the 2000 dollars in labor and refrigerant again. I have lost faith in this company to do ethical business since I am sure this was the original problem and should have been fixed the first time. They just want to sell new units. Repairs should be handled with another company.
