Ductless Mini Split Systems

Efficient, flexible, and whisper-quiet heating and cooling without the need for ductwork.

How Ductless Mini Splits Work

A mini-split pairs an outdoor unit with one or more indoor units to heat and cool rooms without ducts. Refrigerant moves heat between the units, and inverter controls adjust output to demand.

Benefits of Mini Split Systems

Ductless mini splits offer advantages that conventional HVAC systems simply cannot match.

🌡️

Individual Room Temperature Control

Each indoor unit can control its own room or zone, so you can condition spaces as you use them.

🚫

No Ductwork Required

Mini-splits connect indoor and outdoor units through a small wall opening. They work well for additions and homes without ductwork.

⚡

Exceptional Energy Efficiency

Inverter-driven mini-splits adjust output to match demand, which can reduce wasted energy. Savings depend on your home and existing system.

🔇

Whisper-Quiet Operation

Many mini-splits run quietly, making them a good fit for bedrooms and home offices.

🔀

Versatile Installation Options

Choose from wall, ceiling, floor or concealed indoor units to fit your space and style.

🌬️

Improved Indoor Air Quality

Indoor-unit filters capture some dust and airborne particles. Clean or replace them as the manufacturer recommends.

Single-Zone vs. Multi-Zone Systems

Choose the configuration that best fits your space and comfort needs.

Single-Zone Mini Splits

A single-zone system connects one indoor unit to one outdoor unit. It is a straightforward choice for a bedroom, office, addition or other space needing its own temperature control.

Multi-Zone Mini Splits

A multi-zone system connects several indoor units to one outdoor unit. It provides separate temperature control for multiple rooms without adding ductwork.
