2 Major Knox County Geothermal Heating and Cooling Considerations

1.     Initial Costs vs. ROI

It’s an inescapable fact: replacing your existing HVAC system with a geothermal heating and cooling system is an expensive proposition. Initial costs here in Knox County can run anywhere from $10,000 to $30,000 – or more. Lot size, site accessibility, system configuration, ground conditions, and other factors account for that. So too does the amount of excavation that has to be done and what sort of ductwork modifications are required. And if you’re building a new home? It’s not as budget-busting, normally, but it’ll still cost around 40 percent more than a typical HVAC system will cost you.

Okay, you wanted the bad news first. Now, for the good news. To begin with, some sort of incentives and rebates may be obtainable at the federal, state and local level to help you bear the installation costs. Next, the energy savings you could realize with your new geothermal heating and cooling system will start returning your initial investment almost immediately. So you could recoup your investment in as little as four years. But be advised: Local utility rates and the final cost of your installation may delay full repayment for as much as 15 years. Given that geothermal systems often last for upwards of 30 or 50 years, though, you’ll still make out all right. You just have to calculate sooner rather than later what your finances can withstand … and how patient you are.

2.     Geothermal Benefits Can Easily Override Any Anxieties About Starting Costs

Allow us to rattle off the top benefits:

  • Compared to ordinary heating and cooling systems, geothermal heating and cooling could nick 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 taken from the ground.
  • Geothermal heat pumps don’t operate by combustion, so you’re not bothered 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 required, geothermal heating and cooling systems run much quieter than common systems.
  • Since there are so few moving parts and geothermal systems are shielded from the elements, you’re pretty much guaranteed many decades of low-maintenance, top-performance use. Indoor components may last about 30 years, ground loops, about 50.
