Geothermal Heat Pump Problems? Tips to Try Before the Pros Arrive

Despite the reliability of these systems, geothermal heat pump problems do occur. If the geothermal system in your Delaware-area home isn’t working as it should, the problem may be something you can take care of yourself. Other issues require help from a professional, but a little quick troubleshooting can make your technician’s job easier.

Check your control panel

Your system’s control panel has indicator lights to alert you to problems. If none of these lights are on, the system may not be receiving electricity. If either the HP (high pressure) or LP (low pressure) light is on, you may need a technician to pin-point the cause. Check the power If your control panel lights are out, make sure the system is plugged in and the main power switch is on. Look for power disconnect switches that have been shut off. Check your home’s electrical panel for blown fuses or tripped circuit breakers. Look for airflow problems A clogged air filter can interfere with airflow enough to shut down your system. If your filter is clogged with dust and debris, replace it. Also make sure no registers are blocked by furniture, curtains or other items.

Check the loop pressure

One of the more common geothermal heat pump problems, incorrect loop pressure can cause insufficient heating and cooling or shut down your system completely. The pressure gauge on your system pressurizer should display the manufacturer’s recommended pressure, usually between 50 and 75 psi. If the pressure is incorrect, call an HVAC technician. For low pressure, a technician can repressurize your system and check for leaks that may have caused the drop in pressure. If the pressure is sufficient, make sure the loop pumps are operating. Although many geothermal heat pump problems have simple solutions, all require immediate attention to prevent any permanent damage.
