With eight different models to choose from, packaged heating/cooling systems from Lennox offer easy installation and maintenance. Benefits of packaged units include:
- Space savings – Packaged units have no indoor components, saving you storage room inside your home. Depending on the model, they can be installed on your roof or on the ground.
- Energy efficiency – These systems are designed to reduce energy usage.
- Ease of repair – Because all of the components are housed together, getting to the affected parts of a packaged unit and fixing them can be less complex than with traditional separate units.
