Upflow / Downflow

Upflow / Downflow Cased Evaporator Coils

Upflow and downflow cased evaporator coils are versatile indoor HVAC coils designed to work in vertical airflow configurations, making them ideal for residential split air conditioning and heat pump systems. These coils are installed inside or with air handlers and furnaces, where they absorb heat from indoor air to support efficient cooling and humidity control.

The key advantage of this category is installation flexibility—upflow coils are used when air moves upward through the system, while downflow coils are used when air moves downward, such as in attic or rooftop installations.

What you’ll find here

  • Vertical cased evaporator coils (upflow configuration)
  • Vertical cased evaporator coils (downflow configuration)
  • AHRI-matched coil and condenser combinations
  • R-32 and R410A compatible coil models (system dependent)
  • High-efficiency coils for modern SEER2 systems
  • Coils designed for furnace or air handler integration

How to choose

  • Match coil tonnage with your outdoor condenser for proper system balance
  • Select upflow or downflow based on your installation orientation
  • Ensure compatibility with refrigerant type (R-32, R410A, etc.)
  • Verify cabinet size compatibility with your furnace or air handler
  • Look for AHRI-rated matched systems for verified performance
  • Consider coil design for optimal heat transfer and low airflow resistance
  • Check drain pan design for proper condensate management

Upflow vs Downflow Coils

  • Upflow coils: Air moves upward through the coil, commonly used in basements or lower-level installations
  • Downflow coils: Air moves downward, typically used in attics or rooftop systems
  • Upflow systems: More common in residential HVAC setups
  • Downflow systems: Used where ductwork is installed above the unit

FAQ

What is an upflow evaporator coil?
It is a coil designed for systems where air flows upward through the furnace or air handler.

What is a downflow evaporator coil?
It is a coil designed for systems where air flows downward through the HVAC unit.

Can one coil work for both upflow and downflow?
Some models are multi-position, but most are specifically designed for one airflow direction.

Do I need to match the coil with my condenser?
Yes. Proper matching is essential for efficiency, performance, and system reliability.

Where are these coils installed?
They are installed with air handlers or furnaces inside the home, depending on airflow direction.

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