Your geothermal system is like the quiet genius of your home's comfort — efficiently heating and cooling your space while keeping energy costs low and the planet happy. Sometimes, your geothermal system might act up. When trouble strikes, One Hour Heating & Air Conditioning® is ready to get your system back in shape.

Geothermal systems use the Earth’s steady underground temperature to move heat through a buried loop — sealed underground piping that circulates a heat‑transfer fluid — and an indoor heat pump. These reliable, long-lasting systems deliver quiet, even comfort year‑round and can help lower energy costs. They also come with lower emissions and reduced maintenance needs since they do not burn fuel. Homeowners with geothermal systems enjoy consistent indoor temperatures all year long.

Top Geothermal Problems to Look Out For

If your geothermal system is showcasing some issues, don't panic! Call One Hour Heating & Air Conditioning® if you notice any of the following:

Unusual Noises

Geothermal systems are usually quiet, so if yours starts sounding like a garage band warming up, something's off. Grinding, banging, or hissing noises could point to issues with the heat pump, a refrigerant leak, or other internal components. If your system starts making sounds you only hear in nightmares, give us a call at (855) 487-0097.

The Geothermal Unit Is Not Cooling or Heating Evenly

A functioning geothermal system should keep your home consistently comfortable. If you're sweating in one room and shivering in another, something is wrong. Uneven temperatures or a system that struggles to maintain the set temperature might mean problems with the ground loop, compressor, or airflow. Contact the experts if your geothermal AC is not cooling your space on a hot day.

Energy Bills Climbing

Geothermal systems are known for their efficiency, so if your energy bills suddenly spike, it might be a sign your system is working overtime to make up for hidden issues. Faulty components, refrigerant leaks, or loop system problems can cause your unit to drain more energy. 

Suspicious Puddles Around the Unit

If you notice water pooling around your geothermal unit, this could signal trouble. Leaks might come from the condensation drain, internal connections, or even the ground loop. Addressing leaks quickly prevents water damage and keeps your system running as it should. 

Your System Is Short Cycling

Is your system turning on and off like it's indecisive? That means it's short cycling. There could be an issue with the thermostat, a clogged filter, or another malfunction. Frequent cycling wears out components faster and leads to inconsistent heating and cooling — so it's worth giving us a call to check it out.

Frozen Ground Loop

A frozen ground loop can stop your system in its tracks. Since the loop is buried underground, this is a job for the experts. If your system suddenly stops working, frozen geothermal system pipes may be the culprit. A professional repair is the fastest way to get things flowing again.
