• Proper installation protects eligibility for manufacturer warranties and local rebates, many of which require certified installers and documented permits.

Common Heat Pump installation types and when to choose them

• Ductless mini-split and multi-split systems
• Best for homes without existing ductwork, additions, or rooms needing independent temperature control.
• Pros: zone control, high seasonal efficiency, minimal disruption during installation.
• Considerations in Sammamish homes: wall placement to avoid prevailing wind and moisture exposure; aesthetic concerns in neighborhoods with HOA rules.
• Central heat pump (air handler with ductwork)
• Ideal for homes with existing ductwork in good condition or during whole-house HVAC replacements.
• Pros: even whole-house conditioning, often lower upfront cost for large spaces when ductwork is adequate.
• Considerations: duct leakage, insulation, and balancing are common issues in older Sammamish homes and should be corrected to realize promised efficiency gains.
• Hybrid systems
• Combine a heat pump with a gas furnace for cold-climate backup or intermittent extreme cold.
• In Sammamish this is less often required, but may be chosen for redundancy or to preserve existing heating equipment.

Initial site assessment and load calculations

• Accurate sizing begins with a Manual J load calculation performed for your specific Sammamish home. This evaluates:
• Square footage, ceiling heights, insulation levels, window types and orientation, air infiltration, and local design temperatures.
• Site assessment includes:
• Exterior space for the outdoor unit with clearance for airflow, service access, and consideration of prevailing breezes and snow accumulation.
• Interior locations for air handlers or indoor units that provide optimal distribution and minimize run lengths for refrigerant lines.
• Electrical service review to check panel capacity, breaker sizing, and whether an upgrade or subpanel is necessary.
• Duct inspection for central systems assessing leakage, insulation R values, and proper sizing for desired airflow.
• A careful assessment ensures correct heat pump capacity, prevents short cycling, and maximizes seasonal performance metrics like HSPF and SEER.

Selecting the right heat pump equipment

• Match capacity to heat load, not room size alone. Heat pumps operate most efficiently when running steadily to meet a load they are sized to handle.
• For Sammamish winters, prioritize:
• Cold climate heat pumps with efficient low ambient performance and robust defrost cycles.
