What is a ductless mini split system?

A ductless mini split system is a heating and cooling solution that conditions individual rooms or zones without using ductwork. It typically includes an outdoor unit connected to one or more indoor air handlers.

How do I choose the right size ductless mini split?

Sizing depends on room size, insulation quality, ceiling height, sun exposure, and overall heat load. A professional load calculation is the best way to determine the correct BTU capacity for efficient performance.

Can I install a ductless mini split myself?

While some DIY kits exist, professional installation is recommended to ensure proper sizing, safe electrical work, correct refrigerant handling, and manufacturer-compliant installation for reliable performance.

What are the benefits of a ductless mini split?

Ductless mini splits offer energy efficiency, zoned comfort, quiet operation, and flexible installation without ductwork—making them a great option for additions, older homes, and rooms with hot/cold spots.

How much does it cost to install a ductless mini split?

Costs vary based on the number of zones, equipment selected, and installation complexity. Many installs range from about $3,000 to $5,000, but multi-zone systems or complex installs can be higher.

How long does a ductless mini split installation take?

Many ductless mini split installations can be completed in one day. Multi-zone systems or more complex setups may take longer depending on layout and access.

What maintenance is required for ductless mini splits?
