Packaged HVAC Systems: All-in-One Heating and Cooling
Understand how a packaged unit combines heating and cooling in one outdoor cabinet.
A packaged HVAC system houses the heating and cooling components in a single outdoor cabinet, usually placed on the roof or beside the home. This guide explains how packaged systems work and where they make sense.

What to know about packaged systems
- All heating and cooling components in one outdoor cabinet
- No indoor air handler taking up closet or attic space
- Common on homes with flat roofs or limited indoor space
- Connected to ductwork that runs to and from the unit
- Available as cooling-only, heat pump, or gas/electric combinations

Is a packaged system right for your home?
- Your home’s roof type and available ground space
- Existing ductwork layout and where it currently runs
- Whether your home already has a packaged unit
- Indoor space constraints for an indoor air handler
- Access for installation and future service
