Geothermal Heat Pump Service & Repair in Seattle

Geothermal heat pumps are some of the most efficient heating and cooling systems a home can have, but only when they're running right. Greenwood Heating and Home Services repairs and maintains geothermal systems of all makes and ages for homeowners across Seattle and King and Snohomish counties, including older WaterFurnace systems such as Envision and Synergy3D models.
How Geothermal Heat Pumps Work
A geothermal (or ground-source) heat pump circulates water or an antifreeze solution through a loop of pipe buried in the ground, where the temperature stays fairly steady all year. In winter, the heat pump inside your home pulls heat from that fluid and delivers it through your ductwork or radiant floors. In summer, the process reverses, moving heat out of your home and into the cooler ground. Many systems also help heat your water.Because the indoor heat pump does the hard work year-round, it needs the same regular care as any other heating and cooling system.
Our Geothermal Services
Geothermal Repair
When your geothermal system stops heating or cooling, short cycles, or shows a lockout or fault code, our technicians diagnose the indoor heat pump, compressor, blower, controls, and thermostat, and get your system running again.
Geothermal Maintenance
An annual tune-up keeps your geothermal system efficient and catches small problems early. Our maintenance visits include inspecting and cleaning key components, checking system pressures and temperatures, testing safety controls, and replacing your air filter.
24/7 Emergency Service
Geothermal systems can fail on the coldest night of the year, just like any other heating system. Our team offers 24/7 emergency service throughout the Seattle area.
Signs Your Geothermal System Needs Service
- Not enough heat or cooling: The system runs, but your home never reaches the temperature on the thermostat.
- Lockouts or fault codes: The heat pump shuts itself off or shows an error on the unit or thermostat.
- Backup heat running often: If your auxiliary or emergency heat runs much more than usual, the heat pump may not be keeping up.
- Rising energy bills: A geothermal system that's suddenly costing more to run usually has a problem worth checking.
- New noises: Grinding, buzzing, or banging from the indoor unit points to a part that needs attention.
- Short cycling: The system turns on and off every few minutes instead of running full cycles.

Frequently Asked Questions About Geothermal Service in Seattle
Do you install geothermal systems?
No. We service and repair all geothermal heat pump systems, but we don't install new geothermal systems or ground loops.
Do you work on older WaterFurnace systems?
Yes. We service WaterFurnace systems, including older Envision and Synergy3D models, along with geothermal heat pumps from other manufacturers.
How often does a geothermal heat pump need maintenance?
Once a year is a good rule of thumb. Regular maintenance helps the system run efficiently and catches small problems before they turn into breakdowns.
How much does geothermal repair cost?
It depends on the part that failed and how easy it is to reach. We'll diagnose the problem and give you an upfront price before any work begins. A diagnostic or trip fee may apply, depending on your Club Membership level.
What's the difference between geothermal and a regular heat pump?
An air-source heat pump exchanges heat with the outdoor air. A geothermal heat pump exchanges heat with the ground, which stays at a steadier temperature, so it usually runs more efficiently, especially on the coldest and hottest days.
Do Club Membership benefits apply to geothermal systems?
Yes. Club Membership covers geothermal heat pumps, with benefits based on your membership tier.
