Do you need backup heat with geothermal?

• <div><p>If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a <a href="https://www.angi.com/articles/furnace-and-heating-basics.htm">furnace</a> 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.</p></div>

How long do geothermal systems last?

• <div><p>You can expect a geothermal system to last for years. According to the <a href="https://www.energy.gov/sites/prod/files/guide_to_geothermal_heat_pumps.pdf">Department of Energy, </a>the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.</p></div>

Q: Are there downsides to using a geothermal heat pump for floor heating?

• <div><p>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. </p></div>

Q: How often should I have my HVAC system serviced?

• <div><p>For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement. </p></div>

Q: What are the benefits of geothermal heating and cooling?

• <div><p>Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.</p></div>

Very responsive staff. Arrived on time and were able to get replacement part pretty quickly to repair hot water problem (did not need to buy new tankless water heater). Work looked to be done very well. Best of all, their cost was much lower than other estimates I received.
