The big advantage with the new series of Goodman 2. 5 Ton Air Handler With TXV Model ARPT30B14 is found in the Smart frame sub structure, which adds great durability and lateral stability to the inbuilt chassis. In turn, this not only ensures some extra insulation retention, but also provides a completely new mounting location for its components. Furthermore, with the Goodman , there is no need to fix screws externally, sidewise and on the backside anymore. Another added benefit that is valued greatly by buyers is that of its unique 4 way multi dimensional and positioned airflow directions. For maximum performance, these models are available in paint finish and a factory-mounted thermal expansion valve.
