Washington State's climate, with its extended periods of rainfall and moderate temperatures, presents unique considerations for ductless AC installation. While the primary demand is often for cooling during the warmer summer months, the increasing popularity of ductless heat pumps for efficient winter heating cannot be overlooked. Our installations are meticulously planned to comply with Washington's building codes, ensuring that all work is performed to the highest safety and performance standards. System sizing is a critical component; accurately calculating the cooling and heating loads based on building envelope characteristics and the specific microclimate of the Seattle area is essential for optimal efficiency and comfort. The prevalent housing stock, including many older homes and newer, highly insulated residences, makes ductless systems an ideal solution for providing targeted, zone-controlled comfort without the extensive infrastructure of traditional ducted systems.
