A heat pump is the most versatile HVAC system you can install in a Kirkland home — one unit handles heating, cooling, and dehumidification year-round. Kirkland’s climate sits in the efficiency sweet spot for heat pumps: winters hover between 35°F and 50°F, and summers are getting hot enough that central cooling has become essential. We install ducted, ductless, and dual-fuel heat pump systems across Kirkland with proper load calculations, equipment sizing, and full permitting.
Heat Pump Options for Kirkland Homes
Ducted heat pump — connects to your existing ductwork and replaces or supplements your furnace for heating and cooling. The outdoor compressor connects to an indoor coil at the air handler. Best for homes with existing forced-air systems. Cost: $9,000 to $16,000 installed. PSE rebates and the 25C tax credit can offset $1,500 to $2,000.
Ductless mini split heat pump — delivers heating and cooling through wall-mounted, ceiling-mounted, or ducted indoor units without ductwork. Best for older Kirkland homes without ducts, additions, ADUs, and converted garages. Single-zone cost: $3,500 to $6,000. Multi-zone (whole home): $10,000 to $18,000.
Dual-fuel heat pump — a heat pump paired with an existing gas furnace. The heat pump handles heating above 35°F (roughly 350 days per year in Kirkland), and the furnace provides backup for the coldest nights. This configuration gives the efficiency benefits of a heat pump without giving up gas backup. Cost: $10,000 to $16,000 installed.
Air-source versus ground-source — air-source heat pumps are standard for residential installations. Ground-source (geothermal) systems offer higher efficiency but cost $20,000 to $35,000 and require significant yard excavation. For most Kirkland homes on standard lots, air-source heat pumps deliver the best return on investment.
Cold-climate models — standard heat pumps lose efficiency below 30°F and may not keep up below 20°F. Cold-climate models (Mitsubishi H2i, Daikin!”Aurora, Carrier Greenspeed) maintain heating capacity down to -13°F. Kirkland rarely drops below 25°F, so cold-climate models are not strictly necessary — but they provide better performance during the occasional deep freeze and are required for some PSE rebates.
Ducted heat pump installation is the most common HVAC upgrade for Kirkland homes with existing forced-air systems. We remove the old AC condensing unit (or add one if the home only had a furnace), install the new heat pump outdoor unit, connect it to a matching indoor coil, and configure the thermostat for heat pump operation. If the home has a gas furnace, we set up dual-fuel operation so the furnace provides backup heat below a programmable switchover temperature. We install ducted heat pumps from Trane, Carrier, Lennox, and Goodman.
Ductless heat pump mini splits are the go-to solution for Kirkland homes without ductwork. We install Mitsubishi, Daikin, Fujitsu, and LG systems in single-zone and multi-zone configurations. Each indoor unit provides independent temperature control for its room or zone. Multi-zone systems with three to five indoor heads can condition an entire Kirkland home from one outdoor unit. We handle refrigerant line routing, condensate drainage, electrical circuits, and commissioning.
Replacing an aging gas furnace and AC with a single heat pump system simplifies your HVAC and eliminates gas costs. We install heat pump systems sized for your home’s full heating and cooling load. In Kirkland, a properly sized heat pump handles 95% of heating days without backup. For the rare sub-freezing nights, we can include electric strip heat in the air handler or keep the existing gas furnace as a dual-fuel backup.
Heat pump water heaters use the same technology as HVAC heat pumps but apply it to domestic hot water. They are two to three times more efficient than standard electric water heaters and qualify for federal tax credits. We install heat pump water heaters from Rheem and A.O. Smith. The units need adequate space and ventilation — closet installations may require modifications. Kirkland homeowners replacing electric tank water heaters see significant savings on monthly utility bills.
PSE offers rebates up to $1,500 on qualifying heat pump installations. The federal 25C energy tax credit covers 30% of equipment and installation costs, up to $2,000, for heat pump HVAC systems. Washington State may also exempt qualifying equipment from sales tax. We provide all documentation needed for rebate applications and tax credit filing. The combined incentives can reduce the net cost of a heat pump installation by $2,000 to $3,500.
Heat pump installation is a precision job. The system has to be sized correctly for your home, the refrigerant charge has to be exact, and the thermostat has to be configured for heat pump operation — not furnace operation. Mistakes in any of these areas cause efficiency losses, comfort problems, and premature equipment failure.
Manual J load calculations — proper sizing for your specific home.
Cold-climate expertise — we know which models perform best in Kirkland’s damp winters.
Rebate and tax credit guidance — we maximize your savings on qualifying systems.
Full permitting and inspection — King County mechanical permits handled start to finish.
