What Stillwater homeowners ask about "Heat Pump Installation" — quick answers
- Why does a geothermal heat pump cost so much more than an air-source one?
- Most of the extra cost is the ground loop — trenching a horizontal field or drilling vertical bores. That buried loop is what gives geothermal its low operating cost and long life, but it makes the upfront price site-dependent. Get the loop type and footage in writing before you compare bids.
- What credentials should a geothermal installer have?
- Beyond an HVAC license and EPA 608, look for IGSHPA accreditation and a manufacturer authorization such as WaterFurnace GeoPro or ClimateMaster. The loop drilling is separately licensed in many states — often under well-driller rules — so confirm who holds that credential.
- What inspection and paperwork should be included after a heat pump installation in Stillwater?
- The final deliverables should include the permit closing documentation (final inspection sign-off), a signed inspection report, the Manual J or load calculation, equipment warranties (advertised), and commissioning notes detailing charge and airflow adjustments.
