Common Questions

Is the Carrier 48TM400755 compatible with R-22 or Puron systems?
This evaporator coil is specifically designed for use in modern Carrier package units utilizing Puron (R-410A) refrigerant, which operates at higher pressures than legacy R-22 systems. Always verify your unit's data plate before installation.

What are the signs that a 48TM series evaporator coil needs replacement?
Common indicators for Carrier evaporator coil failure include visible refrigerant leaks, excessive fin corrosion that restricts airflow, or a significant drop in cooling capacity and increased energy consumption on the rooftop unit.

How can I ensure the longevity of this replacement coil?
Regular maintenance is key. Technicians should perform seasonal cleanings with approved commercial coil cleaners, flush the condensate pan, and ensure filters are replaced to prevent debris buildup on the fin surfaces.
