Versatile HVAC Systems for Endless Comfort Possibilities
Ductless systems are becoming an increasingly popular HVAC choice across North America. They heat and cool homes and businesses without the need for traditional ductwork, often referred to as "mini-splits." These systems connect a single outdoor unit to one or more indoor units via flexible refrigerant tubing, making them simple to install almost anywhere. Because ductless units are placed directly in the room, they offer precise temperature control, better energy efficiency, and cost-effective comfort year-round.

Viessmann ductless systems use inverter technology that continually adjusts compressor speed based on changing conditions for consistent comfort and lower energy usage. They provide powerful low ambient heating and cooling down to -22°F (-30°C), with 100% heating capacity at 5°F (-15°C).
Challenges Ductless Systems Can Solve
- Older buildings with baseboard heating or no ductwork
- Rooms that are difficult to heat or cool
- Attic or garage buildings
- Tight quarters
