i have an agreement with a contractor to install two units in my colonial style house originally we were talking about Carrier units then he told me he could save me some money with York units. I now have a new estimate for Luxaire units TCJF30S41S3A and AHE30B3X21A which are supposed to be made by Johnson Controls & York. My concern is the quality i just would like an honest opinion before i sign and commit with payment. Thanks Tom
