MINI-SPLITS

A mini-split, also known as a ductless air conditioning system, is a compact HVAC system that can efficiently heat and cool single rooms, small apartments, and other spaces where ductwork isn’t practical or feasible. Like standard heat pump-based systems, a mini-split consists of two primary components: an outdoor compressor/condenser unit and one or more indoor air handlers.

Mini-split systems are ductless, compact solutions ideal for small spaces or individual rooms, offering flexibility and high efficiency without requiring ductwork. Central air systems, on the other hand, use ducts to distribute air throughout an entire home, making them better suited for larger spaces with existing infrastructure. Your choice depends on your home's size, layout, and whether ductwork is already in place. Learn more on mini-splits vs central air: which is right for you?

Yes, a mini-split system can both heat and cool. It cools by extracting heat from indoor air and transferring it outdoors, and heats by reversing the process, pulling heat from outdoor air and bringing it inside. This compact system efficiently handles temperature control without requiring ductwork.

With the right application, mini-splits have some obvious benefits: flexibility and ease of installation, efficiency and cost-savings, improved indoor air quality, multi-zone comfort, and minimal noise.
