MRCOOL mini split heat pumps can provide both heating and cooling, just not at the same time. The mini split air conditioners or AC units cannot heat.

Mini split systems typically last between 10-15 years but you can find some that last 20-30 years. This can depend on the manufacturer or specific unit as well as where you live. In coastal areas, the lifespan may be shorter.

Mini split systems control the temperature in a single or multi-zone space. This means they work best to cool individual rooms instead of an entire home or building. Mini splits provide precise cooling in each room. If you live in a home or apartment without existing ductwork, mini splits offer a more affordable cooling system than central air.

Central systems can control the temperature of an entire home or building. They use ductwork to transfer this air. They typically use a single thermostat to control the temperature in an entire home and often work along with a heating system like a furnace.

Package terminal air conditioners, also called PTACs, install directly through the wall. As a single unit, a PTAC requires only the unit itself. They do not require ductwork. Traditionally, they work in hotels, but they can also see use in dormitories, senior centers, and other similar locations.

MRCOOL offers both package terminal heat pumps and air conditioning units. Their package terminal AC ranges from 9K BTU per hour to 15K BTU per hour. Their package terminal heat pumps range from 7K BTU per hour up to 15K BTU per hour.
