What Is a Package HVAC Unit?
A package HVAC unit combines all the heating and cooling components into one cabinet. This unit is typically installed outside, either on the ground next to the building or on the roof. Inside, it contains the compressor, condenser, evaporator coil, and air handler, making it a true all-in-one system.
Because everything is self-contained, package HVAC systems connect directly to ductwork. They’re common in commercial buildings, mobile homes, and houses with limited indoor space.
Key Features of Package HVAC Units:
- All-in-one design with both heating and cooling in one cabinet
- Outdoor installation (ground-level or rooftop)
- Easy connection to ductwork
- Often available in gas/electric or all-electric models
What Is a Split HVAC System?
A split HVAC system separates the heating and cooling components into two units: an outdoor unit and an indoor unit. The outdoor unit houses the compressor and condenser coil, while the indoor unit contains the evaporator coil and air handler. Refrigerant lines connect the two.
Split systems are the most common residential HVAC choice in the U.S. They can be paired with a furnace or a heat pump, offering flexibility for homeowners.
Key Features of Split HVAC Systems:
- Two-part design (indoor and outdoor units)
- Indoor unit located in a basement, attic, or closet
- Outdoor unit installed on a concrete pad
- Can work with a furnace or heat pump
Package HVAC Units vs. Split Systems: The Main Differences
-
1. Space Requirements
- Package Unit: Ideal for homes without basements or attics, since everything is outside.
- Split System: Requires indoor space for the air handler or furnace but offers more flexibility. 2. Installation
- Package Unit: Simpler installation; all-in-one cabinet connected directly to ductwork.
- Split System: More complex installation; requires connecting indoor and outdoor units. 3. Energy Efficiency
- Split System: Typically, more energy-efficient, with better insulation and performance.
- Package Unit: Convenient, but sometimes less efficient in extreme climates. 4. Maintenance and Repairs
- Package Unit: Easier to access since all parts are in one place, but more exposed to weather.
- Split System: Indoor components are protected, but maintenance requires servicing two areas. 5. Lifespan
- Split System: Often lasts longer since indoor components are shielded from outdoor weather.
- Package Unit: Still durable but more exposed, which can shorten lifespan. 6. Cost
- Package Unit: Usually less expensive to install due to simple design.
- Split System: May cost more upfront but can save money over time with better efficiency.
Which HVAC System Is Right for You?
Choose a Package Unit If:
- You have limited indoor space
- You want a quick, simple installation
- You’re replacing an existing package system
- You prefer all components outdoors
Choose a Split System If:
- You have attic, basement, or closet space available
- You want higher energy efficiency
- You plan for long-term investment in HVAC
- You prefer quieter indoor operation
Final Thoughts
When comparing a package HVAC unit vs. a split system, the right choice depends on your home’s space, budget, and energy efficiency goals. Package units save space and simplify installation, while split systems offer flexibility and long-term performance advantages.
