Cased Evaporator Coils

Cased evaporator coils are factory-enclosed indoor HVAC coils designed for central air conditioning and heat pump systems. Housed in a protective metal cabinet, these coils are installed directly with air handlers or furnaces to absorb heat from indoor air and support efficient cooling and dehumidification throughout the home.

Because they come pre-cased, these coils are easier to install, better protected from airflow leakage, and more consistent in performance compared to uncased coils. They are widely used in residential split systems where reliability, efficiency, and proper system matching are essential.

What you’ll find here

  • Vertical and horizontal cased evaporator coils
  • AHRI-matched coil and condenser combinations
  • R-32 and R410A compatible coil systems (model dependent)
  • High-efficiency coils for SEER2-rated systems
  • Coils designed for air handlers and gas furnace pairings
  • Multi-position compatible cased coil units

How to choose

  • Match coil tonnage with your outdoor condenser (critical for system efficiency)
  • Ensure compatibility with refrigerant type (R-32, R410A, etc.)
  • Choose correct orientation (upflow, downflow, horizontal) for installation space
  • Verify cabinet size compatibility with your furnace or air handler
  • Look for AHRI-rated matched systems for validated performance
  • Consider coil design for better heat transfer and reduced pressure drop
  • Check condensate drain pan design for proper moisture handling

Cased vs Uncased Evaporator Coils

  • Cased coils: Fully enclosed in a metal cabinet, easier installation and better airflow control
  • Uncased coils: Installed inside furnace or air handler cabinets, more flexible but require precise fitting
  • Cased coils: Better protection against air leaks and physical damage
  • Uncased coils: Often used in custom or tight-space installations

FAQ

What is a cased evaporator coil?
It is an indoor HVAC coil enclosed in a metal cabinet that works with your air conditioner or heat pump to cool indoor air.

Do cased coils improve performance?
Yes. Their sealed design helps reduce air leakage and improves overall system efficiency.

Can cased coils be used with heat pumps?
Yes. Many cased coils are compatible with both heat pump and central AC systems.

Are cased coils easier to install?
Yes. The pre-built casing simplifies installation and alignment with other HVAC components.

How long do evaporator coils last?
Typically 10–15 years depending on usage, maintenance, and environmental conditions.

Do I need professional installation?
Yes. Proper installation ensures correct refrigerant charging, airflow matching, and system performance.
