Why mini-splits make sense for Kirkland homes

Kirkland’s climate presents unique comfort and efficiency challenges: wet, cool winters; mild but humid summers; and many properties that benefit from zoned temperature control rather than ducted systems. Mini-splits deliver efficient heating and cooling directly to living spaces, avoiding the energy losses of ductwork in older houses. They also allow precise temperature control for individual rooms, which is ideal for Kirkland families who want warm living areas without overheating the whole home. For waterfront or near-lake properties, minimizing the need for interior ductwork decreases the risk of moisture-related issues.
