Heating Oil questions, answered by experts

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

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

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
