My 12 year old ruud package unit has been leaking Freon for 3 years off and on and no one can solve the problem. I am not sinking anymore money into it. Does anyone have any info to offer on the following 2 replacement units I am looking at. I live in southeast TN and run the ac 9 months a year. The house is 3200 sq ft with 3 levels. The old unit was a 4 ton. We have always had problems keeping the top level cool without freezing some people on the middle level, but hay, I like it cold. I have asked two companies if I could go to a 5 ton and after visually inspecting my ducts they both said they thought I could.
Carrier 48VL 14 seer variable speed
Trane XL14 14 seer variable speed
There is only $200 difference in the price of these 2 units after rebate and tax credit. Does anyone have any experience with either of these units and is one better than the other?
