Heating Oil questions, answered by experts

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

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
