What Makes a Geothermal HVAC System Worth It?

January 16, 2021

Using heat pumps, geothermal HVAC systems transfer heat from the Earth into a building. It’s an Eco-friendly and cost-effective way to heat your North Myrtle Beach, SC, home. However, the worthiness of a geothermal HVAC system depends on how you weigh the pros and cons.

Financial Pros and Cons

Geothermal HVAC has upfront costs of $10,000-$20,000. But significantly reduced energy bills, low maintenance costs and fewer repairs mitigate these high upfront costs. In fact, renewable, solar energy makes geothermal HVAC the most cost-effective heating system.

Efficiency Pros and Cons

Electricity fuels geothermal heat pumps, but geothermal HVAC still uses less electricity than other HVAC systems.

Geothermal systems that use wells also need large amounts of water. This could increase your water bill.

However, geothermal is a renewable energy source. Its HVAC systems are 300% to 500% efficient and becoming more efficient every year.

Energy Safety Pros and Cons

Generally, geothermal energy doesn’t overuse natural resources or emit greenhouse gases. It’s a clean, green energy source that reduces air pollution. Geothermal heat also dehumidifies the air and reduces allergens and other respiratory irritants.

Like all HVAC systems and energy sources, geothermal heating has some safety issues. For example, well-pump geothermal systems discharge silica, sulfur dioxide and other toxins into the Earth. Geothermal HVAC can also damage underground loops, leading to complex and costly repairs.

Reliability and Convenience Pros and Cons

Geothermal HVAC systems come with long warranties and typically last longer than conventional systems. Since they have fewer moving parts and no parts outside, geothermal systems experience less wear and tear and require little maintenance. But if there’s an issue, this structure can make it difficult to perform a quick inspection.

Although these systems are compact, they can heat large spaces. They’re also quiet. If you’re swayed by the advantages of geothermal HVAC or have more questions, call Warren-Hay Mechanical for a consultation.
