Geothermal Heat Pump Problems? Troubleshooting Tips

A geothermal heat pump is one of the most trouble-free ways to heat and cool a home in the Delaware area. On rare occasions, though, something may go wrong and you find your system won’t run or isn’t producing the temperatures it should. Although some problems require professional care, others you can easily correct yourself. Troubleshooting your heat pump before you call a technician saves you time and money.

Check the power supply

If the system won’t run, check your home’s electrical panel for tripped circuits. Reset any tripped circuits, but if the circuit trips again, call a technician. You may have an electrical problem. Check the fuse for signs of wear and replace the fuse if necessary. Look over other visible electrical connections for wear.

Check the water supply

No water or too little water flowing through the heat exchanger can lead to pressure problems that cause your geothermal heat pump to malfunction. Check that your loop pump’s running and that your water valve’s operating as it should be and the settings are correct. Take a look at your water flow and adjust it to the correct flow rate.

Inspect the air filter

A dirty air filter interferes with airflow and can reduce your system’s performance or even completely shut down the system. Check your filter monthly and replace it when dirty, which will be every one to three months in most homes. Also, check your registers to ensure they’re not blocked by furniture or other items.

Check loop pressure

Look at the pressure gauge on your system pressurizer to ensure the loop pressure is at the level the manufacturer recommends. If your loop pressure’s low, call a technician to have the system pressurized to avoid damaging your geothermal heat pump components. If none of these troubleshooting steps help, call an HVAC expert.
