Do ductless mini splits work in Oregon’s cold climate?

Yes. Modern ductless mini splits, especially Daikin and Ruud models, are designed for efficient operation in cold Oregon temperatures.

How long do ductless systems last?

Most ductless mini splits last 12 to 20 years with regular maintenance and proper installation.

How many rooms can one ductless system heat or cool?

A single outdoor unit can support between one and eight indoor zones, depending on the size and design of the system.

How often should a mini split be serviced?

Ductless mini splits should be professionally serviced once per year to maintain peak performance and energy efficiency.

Are ductless mini splits more efficient than traditional HVAC systems?

Yes. Ductless systems use inverter-driven compressors, allowing them to run more efficiently and maintain more consistent indoor temperatures.
