When it comes to furnace and AC installation in Washington, we consider the unique weather patterns. The damp, cooler climate west of the Cascades means heating is often a priority, while eastern Washington experiences hotter summers that necessitate effective cooling. The age and type of housing stock also play a role; many homes have older ductwork that might need upgrades for optimal performance.
