Heating Oil questions, answered by experts

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system.

If you have an incredibly small yard, however, you may not have enough space for this type of system.

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

Yes, including optimizing settings and suggesting upgrades if needed.
