Now that fall’s here, homeowners in colder regions are wondering if their heating systems can run smoothly for another fall and winter. As most HVAC equipment lasts no more than 20 years, it’s wise to replace a system reaching the end of its shelf life with a more efficient model. For example, here’s a closer look at why a geothermal heat pump is well worth the investment.

How Geothermal Heat Pumps Work

Whereas many heating systems draw air from outside to warm interiors, geothermal pumps source heat from a few feet underground. In fall and winter, the temperature below the earth’s surface is higher than the air temperature.

Units are available in closed- or open-loop systems. With closed-loop operation, a plastic tube is placed in the ground to circulate antifreeze. Heat is transferred between the antifreeze and the refrigerant in the pump via a heat exchanger. People who live near bodies of water often install open-loop systems, in which water is sourced from a well and flows through the pump to transfer heat to the house. 

How Homeowners Benefit 

Approximately 70% of the energy used to operate a geothermal heat pump is renewable. Since the system doesn’t burn fossil fuels, it releases fewer greenhouse emissions that contribute to the depletion of the ozone layer and global warming.

Due to these environmental benefits, there’s a 26% federal tax credit for installation. Some states allow homeowners to combine this credit with state tax exemptions for geothermal and solar heating and cooling. Additionally, since one unit provides heating and cooling for year-round comfort, you may only have to worry about half the repairs and maintenance costs. 

How to Maintain Equipment

Reducing the strain on heat pump components is the best way to care for the system between professional HVAC maintenance appointments. So the system doesn’t work overtime, install a programmable thermostat and use the “auto” fan setting so that it only operates when needed.

When the unit’s air filter is clogged, parts work harder to pass air through the system, which reduces indoor air quality, increases energy bills, and wears down parts. Most experts recommend changing the filter every six months, though if you have shedding pets or issues with allergies, it may be wise to replace it every two to three months.
