Mini-split systems are heating and cooling units that allow you to regulate the temperature in specific rooms or areas. A split system is a combination of an indoor air-handling unit and an outdoor condensing unit. The indoor air handling unit can be a gas furnace with a coil or heat pump air handler. The outdoor condensing unit consists of a compressor and a condenser coil.

Mini-splits have become increasingly common in recent decades. This is a cost-effective way to heat and remarkable homes where conventional HVAC systems aren’t practical, such as additions and older homes without ductwork.

They’re a good option for room additions where expanding or adding distribution ductwork isn’t an option and for energy-efficient new homes with only a limited space conditioning system.
