Ductless Mini Split Frequently Asked Questions
How does a ductless mini split work?
A ductless mini split system consists of an outdoor compressor unit and one or more indoor air handlers mounted on the wall or ceiling. The outdoor and indoor units are connected by refrigerant lines through a small hole in the wall. The system moves heat between inside and outside—heating in winter, cooling in summer—without any ductwork required.
Can a ductless mini split heat effectively in cold Michigan winters?
Modern ductless mini split systems are designed to operate efficiently at cold temperatures, with many cold-climate models rated to heat effectively down to -13°F or lower. They are a viable heating solution in Michigan, though very old or lower-end mini split systems may be less effective at extreme cold. We can help you select a system rated for Michigan's climate conditions.
How many zones can a mini split system support?
Multi-zone mini split systems can typically support between two and eight indoor units connected to a single outdoor compressor, depending on the system's capacity. Each zone is controlled independently, allowing different temperature settings in different areas of the home or building. Contact us to discuss the right configuration for your space.
