Mr Cool Packaged Gas Electric Systems — AC Units for Less

What Is a Mr Cool Packaged Gas Electric System?

A mr cool packaged gas electric system is an all-in-one HVAC unit that combines gas heating and electric cooling inside a single outdoor cabinet.

A packaged gas electric system puts the whole thing outside, the compressor, the evaporator coil and the gas furnace in one complete unit, instead of a split system with indoor and outdoor parts. 

It connects directly to your home's existing ductwork through the wall or rooftop, making it a clean, space-saving solution for homes without an indoor mechanical room.

At AC Units for Less, we carry the full Mr Cool Signature Series packaged gas electric systems lineup—from 2-ton up to 5-ton, with gas furnace options ranging from 60,000 to 115,000 BTU.

How a Gas Electric Package Unit Works

A mr cool package unit uses two separate energy sources for heating and cooling—natural gas for heat and electricity for cooling.

In summer, the electric cooling side runs the compressor to pull heat out of your home and release it outside. In winter, the gas furnace ignites to deliver fast, powerful heat through your existing ductwork.

This dual-fuel approach makes packaged gas electric systems a strong choice in colder climates where gas heating is more cost-effective than electric heat strips or a heat pump alone.

Why homeowners choose a gas electric package unit:

• No indoor air handler or furnace needed — everything is outside
• Gas heat delivers faster warm-up times than electric alternatives
• Ideal for homes on slab foundations or with crawl space access
• Direct replacement for existing packaged rooftop or ground-level units
• Multi-position design — installs horizontal or downflow

Mr Cool Packaged Gas Electric vs. Other System Types

Not sure which system type fits your home? Here's a quick breakdown.

A Mr Cool packaged heat pump heats and cools using refrigerant alone—no gas line required. It's the right pick for mild-to-moderate climates where temperatures rarely drop below freezing for extended periods.

A mr cool packaged gas electric unit is better suited for colder climates where gas heat is more efficient and cost-effective during harsh winters. If your home already has a natural gas line, this system takes full advantage of it.

A Mr Cool split air conditioner pairs an outdoor condenser with an indoor air handler for cooling only — a different setup entirely from a packaged unit.

If you're replacing an existing ground-level or rooftop packaged unit, the mr cool package unit Signature Series is a direct fit in most cases.
