Why Seattle Geothermal

Wrong installer means ground loop failures and years of wasted energy dollars

Undersized systems leave rooms cold in winter. Poorly installed ground loops leak refrigerant. You need IGSHPA-certified professionals who size systems for Seattle's marine climate and handle ground loop work in glaciofluvial soils.

Common Challenges

Heating bills spiking with outdated gas furnace
Old gas furnaces operate at 80% efficiency while ground-source heat pumps deliver 300-400% efficiency. Seattle homeowners waste $1,200-$2,000 annually on heating costs that geothermal systems eliminate through ground heat exchange.
Unclear total price with ground loop work
Quotes that omit ground loop excavation depth, piping length, or Seattle permit fees leave homeowners facing surprise costs mid-project. Glaciofluvial soil conditions in Seattle require site-specific loop sizing that generic quotes miss entirely.
Yard disruption from digging ground loops
Ground loop installation requires excavating 4-6 foot trenches or drilling 150-300 foot boreholes. Without clear timelines and restoration plans, homeowners face weeks of torn-up yards and delayed landscaping projects.

How We Help

40-60% lower heating bills year-round
Ground-source heat pumps extract stable 50-55°F ground heat in Seattle's mild climate, delivering 3-4 units of heat per unit of electricity consumed. Typical Seattle homes save $800-$1,400 annually compared to gas furnaces.
Ground loops last 50+ years with minimal maintenance
High-density polyethylene ground loop piping carries 50-year warranties and requires no maintenance once installed. Indoor heat pump units last 20-25 years with annual filter changes, outlasting conventional HVAC by a decade.
30% federal tax credit plus Seattle City Light rebates
Federal tax credit covers 30% of total installation cost including ground loop and indoor unit. Seattle City Light offers additional rebates up to $1,500 for qualifying systems, reducing net cost by 35-40%.
Systems sized for Seattle's marine climate
IGSHPA-certified professionals calculate heating load based on Seattle's 8,000 heating degree days and high rainfall patterns. Proper sizing prevents short-cycling and ensures consistent comfort in Queen Anne Hill single-family homes and Ballard multi-unit properties.
Clear quotes covering ground loop depth and permits
Upfront pricing includes ground heat exchanger excavation or drilling, piping length for your property size, indoor unit capacity, ductwork modifications, and Seattle permit fees. No hidden costs from site conditions discovered during installation.

Frequently Asked Questions

Common questions about geothermal heat pump installation in Seattle

Clear answers on costs, timelines, and what to expect during installation.

Total installation cost ranges $25,000-$45,000 for Seattle single-family homes, including ground loop excavation, indoor heat pump unit, ductwork modifications, and permits. Ground loop work accounts for 40-50% of cost. Federal 30% tax credit and Seattle City Light rebates reduce net cost by $8,000-$15,000.

Delaying costs $1,200-$2,000 annually in wasted heating expenses as old furnaces operate at 80% efficiency vs 300-400% for geothermal. Emergency furnace replacement in winter costs 20-30% more than planned installation. Missing federal tax credit windows leaves $7,500-$13,500 on the table for typical Seattle homes.

Federal tax credit covers 30% of total installation cost including ground loop, indoor unit, ductwork, and labor through 2032. Credit is claimed on your tax return the year installation is completed. For a $35,000 system, you receive $10,500 credit. Seattle City Light offers additional rebates up to $1,500.

Ground loop excavation takes 1-3 days depending on soil conditions and loop type. Indoor unit installation and system commissioning take 2-3 days. Total project timeline is 1-2 weeks including Seattle permit approval. Yard restoration adds 1-2 weeks after backfilling trenches.

Ground loops require excavating 4-6 foot trenches or drilling boreholes, temporarily disrupting landscaping. IGSHPA-certified installers restore topsoil and grade after backfilling. Piping is buried below frost line with no surface impact. Established trees and hardscaping are avoided during loop layout planning.

Ground-source systems pay back in 8-12 years through $800-$1,400 annual energy savings in Seattle's mild climate. Ground loops last 50+ years and indoor units last 20-25 years, outlasting conventional HVAC. Federal tax credits and rebates reduce net cost by 35-40%, shortening payback to 5-8 years.

Seattle requires mechanical permits for heat pump installation and excavation permits for ground loop work. IGSHPA-certified installers handle permit applications and ensure compliance with Seattle building codes. Permit fees range $500-$1,200 depending on system size and property type.

Most Seattle homes with forced-air systems can use existing ductwork with minor modifications. Ground-source heat pumps deliver air at 90-105°F vs 120-140°F for gas furnaces, requiring larger ducts in some cases. IGSHPA-certified professionals assess duct sizing during site visit and quote any necessary upgrades.
