All-in-One Self-Contained Package Units

All-in-one self-contained package units are complete HVAC systems that combine heating and cooling components into a single outdoor cabinet. These systems provide year-round climate control while saving indoor space, making them a practical fit for homes, modular buildings, light commercial properties, and installations where indoor mechanical room space is limited.

Because all major HVAC components are housed in one unit, package systems simplify installation, maintenance access, and system integration compared to traditional split systems.

What you'll find here

  • Packaged air conditioner systems
  • Gas/electric package units
  • Packaged heat pump systems
  • Rooftop and ground-mounted HVAC package units
  • Residential and light commercial all-in-one HVAC systems
  • Energy-efficient packaged heating and cooling solutions

How to choose

  • Select the correct system type (AC-only, heat pump, or gas/electric package unit)
  • Size the unit using a proper heating and cooling load calculation
  • Compare SEER2 and AFUE ratings for efficiency and operating cost
  • Verify electrical, gas, and ductwork compatibility
  • Consider rooftop or ground installation requirements
  • Ensure airflow (CFM) matches your duct system design
  • Choose variable-speed systems for quieter operation and improved comfort
  • Confirm climate suitability for heating performance needs

Package Units vs Split Systems

  • Package units: All HVAC components are housed in one outdoor cabinet
  • Split systems: Indoor and outdoor HVAC components are separated
  • Package systems: Save indoor space and simplify installation
  • Split systems: Often offer greater installation flexibility and quieter indoor operation
