Debunking 7 Common Geothermal HVAC Myths in Knoxville, TN

Geothermal energy offers a more efficient, environmentally friendly alternative to traditional HVAC systems in Knoxville, TN. Instead of pulling heat from the air around your house, geothermal systems use liquid-filled pipes to draw warm air from the ground, reducing your energy usage and generating consistent warmth. However, myths about geothermal energy, like the ones below, make some homeowners reluctant to switch.

Geothermal HVAC Is Expensive

It’s true that geothermal energy is typically more expensive initially than heat pumps. However, the government offers tax rebates that help you offset the cost. Ask an HVAC professional how much state and federal programs could help.

Once your new system starts running, you’ll notice lower energy bills. Geothermal systems use less fuel than heat pumps and work more efficiently, providing a gradual return on your investment.

For more savings, ask if your property is compatible with an open-loop system. Open loops use groundwater to move heat, while closed-loop systems require water and antifreeze. However, you might need a closed loop system if you don’t have a nearby groundwater source or the local water contains contaminates.

Geothermal Energy Is Overly Complicated

While they might appear complex, geothermal systems have a simple design that’s easy to maintain. Breakdowns are rare because geothermal HVAC has fewer parts than traditional heating equipment and avoids exposure to the elements. Typically, installation takes no more than a few days.

Geothermal Systems Are Geographically Limited

Some people believe the pipes require a lot of space, ruling out geothermal systems for homeowners who live in the city or own small properties. Service technicians can accommodate the layouts for your property size. Vertical loop systems need only a few square feet of space, and properties with aquifers have even more flexibility.

Another myth is that geothermal energy only works in places with year-round heat. Unlike the air outside, which can fluctuate rapidly, the underground temperature remains consistent. Virtually anyone in the United States can invest in a geothermal system.

Geothermal HVAC Is Inefficient

Some people claim that geothermal energy uses lots of water. However, open-loop systems don’t consume water; instead, they circulate water through the system and return it to the ground. Likewise, closed-loop systems circulate water and antifreeze without drawing fresh water from the Earth.

Others believe that geothermal HVAC isn’t environmentally friendly because it uses electricity. This type of system requires power, but compared to furnaces and heat pumps, it burns a smaller amount of fossil fuels.

Plus, geothermal energy is renewable. We might eventually run out of oil, but we’ll never run out of underground heat. These systems also don’t generate greenhouse gases that contribute to climate change.

Geothermal Systems Are Noisy

One myth is that geothermal energy creates more noise than heat pumps. Geothermal HVAC systems run quietly and efficiently, making them suitable for suburban neighborhoods. Low noise pollution promotes better health and concentration.

Geothermal Energy Suits Newer Homes Only

Contrary to popular belief, older houses and modern residences can support geothermal systems. Part of the system is underground, and you don’t need fancy smart home technology to operate geothermal energy. However, geothermal systems can be more challenging to install on older properties, so request a professional consultation before investing.

Geothermal Systems Wear Out Quickly

Despite the myth that heat pumps last longer than geothermal energy, with regular maintenance, a geothermal system could last for decades. The pipes could operate for a century because being underground protects them from damage. Exposed equipment has a shorter lifespan, but you could still get 30 years out of it before purchasing a replacement.
