Geothermal Heating and Cooling, and its Pros and Cons
August 20, 2024
As we continuously seek energy-efficient and environmentally friendly options, geothermal heating and cooling systems are becoming more popular. These types of systems use the Earth's natural heat to regulate indoor temperatures, offering a sustainable alternative to traditional HVAC methods. But before you make the switch, it’s essential to understand both the advantages and potential drawbacks of geothermal technology. Here’s a comprehensive look at geothermal heating and cooling, and its pros and cons.
What is Geothermal Heating and Cooling?
Geothermal heating and cooling systems use geothermal energy, or the Earth's stable underground temperature, to heat and cool your home. A geothermal heat pump circulates a fluid through underground pipes, absorbing heat from the ground. This process transfers heat to or from your home, depending on the season. During winter, the system extracts heat from the ground and transfers it inside. In summer, it reverses the process, removing heat from the home and transferring it to the ground.
Pros of Geothermal Heating and Cooling
- Energy Efficiency: Geothermal systems are among the most energy-efficient heating and cooling solutions available. They can achieve efficiencies of 400% or more, meaning for every unit of electricity used, they produce four units of heating or cooling.
- Environmentally Friendly: By using the Earth's natural heat, geothermal systems significantly reduce greenhouse gas emissions compared to traditional fossil fuel-based systems. They also have a lower carbon footprint, contributing to a more sustainable environment.
- Big Savings: Although the initial installation cost is higher, geothermal systems can help save you money over time. Lower operating costs and energy bills usually offset the upfront investment.
- Longevity and Low Maintenance: Geothermal heat pumps are known for their durability and long lifespan, often lasting 20-25 years for the indoor components and over 50 years for the ground loops. They require less maintenance than conventional HVAC systems since there are fewer moving parts, and no outdoor units exposed to the elements.
- Consistent Comfort: Geothermal systems provide consistent and even heating and cooling, reducing temperature fluctuations and improving overall comfort.
Cons of Geothermal Heating and Cooling
- High Initial Cost: The biggest downside of geothermal systems is the high installation cost. The high price tag is due to the installation process requiring drilling in the ground and installing ground loops, which must be custom fit to each home. However, this cost is typically recovered over time through energy savings.
- Installation Process: Installing a geothermal system requires a lot of space for the ground loops, digging or drilling. This can be difficult or impractical in certain locations, especially in urban areas with limited space.
- Limited Retrofit Opportunities: If your home isn’t already equipped for a geothermal system, retrofitting might be challenging or expensive. Retrofitting refers to changing from one heating system to another. It’s important to determine whether your home’s structure and location are suitable for this type of system.
- Geographical Limitations: The effectiveness of geothermal systems can vary based on geographic location and soil conditions. In regions with poor thermal conductivity or areas with rocky terrain, the efficiency of the system might be impacted.
- Possible Noise Concerns: While generally quiet, some geothermal systems can produce noise, particularly from the circulating pump or compressor. This is usually minimal but worth considering if noise is a concern for you.
Is Geothermal Heating and Cooling Right for You?

When the temperatures drop, a broken furnace can quickly turn into a major headache. Before calling for professional help, there are a few simple checks you can perform to potentially identify and resolve the issue. Here are some common furnace problems and what you should check when it’s not working. 1. Check the Thermostat The thermostat is the control center for your furnace, and often, furnace issues can stem from a simple thermostat setting or power issue. Here’s what to do: Ensure it’s on and set to “Heat”: Double-check that the thermostat is powered on and set to the heating mode. Check the temperature setting: Make sure the temperature is set higher than the current room temperature. Replace the batteries: If your thermostat uses batteries, low power could cause it to malfunction. 2. Inspect the Power Source Your furnace won’t work if it’s not receiving power. Take these steps to make sure it’s properly connected: Check the circuit breaker: Look for any tripped breakers in your electrical panel and reset them if necessary. Examine the furnace switch: Many furnaces have a dedicated power switch near the unit. Ensure it’s in the “On” position. 3. Replace the Air Filter A clogged air filter can restrict airflow, causing your furnace to shut down or operate inefficiently. Follow these steps: Locate the air filter, which is usually near the return air duct or the furnace itself. Check if the filter is dirty or clogged with debris. Replace the filter with a clean one, ensuring it’s the correct size and type for your furnace. 4. Check the Pilot Light or Ignition System If you have a gas furnace , your furnace uses a pilot light, which needs to stay lit for the system to function. For newer models with electronic ignition, the ignitor may need troubleshooting. Here’s what to check: Pilot light: If it’s out, carefully follow your furnace’s instructions to relight it. If it won’t stay lit, there could be a problem with the thermocouple. *Most furnaces that are older than 35 years will have a standing pilot light and thermocouple. Ignition system: For electronic ignitions, you may need to reset the system or call a professional if it’s not sparking properly. *Most furnaces that are 30 years old and newer will have an ignition system that either sparks or glows to light the pilot or burners. Try shutting the power off and turning it back on to reset the system and the furnace will try the ignition sequence again. 5. Ensure the Furnace Door is Secure Many furnaces have a safety switch that prevents them from operating if the access door isn’t properly closed. Ensure the door is securely latched. 6. Look for Blocked Vents or Registers Blocked vents can disrupt airflow and cause your furnace to stop working or overheat. Inspect all vents and registers to: Make sure they’re open and unblocked by furniture or other objects. Remove any visible dust or debris obstructing airflow. 7. Examine the Furnace’s Drainage System If your furnace is a high efficient model that vents to the exterior with PVC pipe, then the condensation from your furnace needs to drain properly. A clogged condensate drain line can trigger safety mechanisms that shut down the system. Check: For water pooling near the furnace . If the drain line is clogged or frozen and clear it if necessary. 8. Examine the Furnace’s exhaust pipe If your furnace is a high efficient model that vents to the exterior with PVC pipe, then the pipes may be covered by a snow drift or be frosted over outside. You can check the type that vent out the sidewall and clear the area as necessary. If your furnace termination vent is on the roof then leave that inspection for a professional as roof access is dangerous, especially during the winter. Once the exhaust and inlet pipes are clear, please shut the power off to furnace and turn back on to reset the control board and re-start the ignition sequence. 9. Listen for Unusual Noises Strange noises can signal specific problems: Banging or rattling: Could indicate loose parts or lack of airflow due to plugged filter or vents. Whistling or squealing: Might point to airflow restrictions or a worn blower belt. Grinding or metal on metal scraping: combustion blower/inducer assembly may be failing, or blower motor / assembly may be failing. While these checks can help address minor issues, some furnace problems require professional attention. If you’ve gone through this list and your furnace still isn’t working, it’s time to call the experts.
