2 Vital Charleston Geothermal Heating and Cooling Considerations

1.     Starting Costs vs. Payback

No doubt about it: replacing your existing HVAC system with a geothermal heating and cooling system is a costly proposition. Starting costs here in Charleston can run anywhere from $10,000 to $30,000 – or higher. Lot size, site accessibility, system configuration, ground conditions, and other issues account for that. So too does the amount of excavation that has to be done and what type of ductwork modifications are needed. And if you’re building a new home? It’s not as pricy, generally, but it’ll still cost roughly 40 percent more than a more common HVAC system will cost you.

Okay, you wanted the bad news first. Now, for the good news. First off, certain incentives and rebates may be available at the federal, state and local level to assist you with installation costs. What’s more, the energy savings you could experience with your new geothermal heating and cooling system will start returning your initial investment in no time. The upshot is, you could recoup your investment in as little as four years. But , then again: Local utility rates and the total cost of your installation may hold up full repayment for as long as 15 years. Because geothermal systems often endure for upwards of 30 or 50 years, though, you’ll still come out ahead. You merely have to decide early on what your finances can tolerate … and how patient you are.

2.     Geothermal Benefits Can Easily Override Worries About Up-Front Costs

Let us list the most important benefits:

  • Compared to conventional heating and cooling systems, geothermal heating and cooling could clip as much as 30 to 60 percent off your heating bills. And it could lower your cooling costs by as much as 20 to 50 percent.
  • Geothermal systems use renewable energy – heat transferred from the ground.
  • Geothermal heat pumps don’t operate by combustion, so you’re not troubled by greenhouse gas emissions (carbon dioxide, carbon monoxide, etc.) and you have no fire safety or air quality concerns.
  • Since no outdoor fans or compressors are necessary, geothermal heating and cooling systems run much quieter than ordinary systems.
  • The absence of many complex moving parts and the fact that geothermal systems are protected from the elements ensure many decades of low-maintenance, top-performance use. Indoor components may last about 30 years, ground loops, about 50.
