Geothermal heat pumps are popular systems for heating and cooling Cincinnati homes. Now's a good time to check your geothermal system for potential problems. Some geothermal issues can be fixed with simple maintenance and easy do-it-yourself projects. Other concerns are more complicated and may be best left for professionals to handle.

If your geothermal unit isn't working properly, be sure to check the system's air filter, water supply and electrical supply. Make sure those necessities are working properly before searching for a deeper problem.

Here are some of the most common geothermal issues, along with suggestions on how best to handle them:

  • The unit doesn't operate in cooling mode - This could be caused by a number of issues, including low refrigerant, defective valves or exchangers, or an improperly located thermostat. Because there could be so many different causes to the problem, it's a good idea to have a professional handle this one.
  • Not heating or cooling sufficiently - Subpar performance could be caused by dirty air filters, a defective fan motor or leaky ductwork. This could be an easy fix if the unit simply needs new filters. Beyond that, it's best to call in professional service.
  • High humidity - This can be caused by either airflow that's too high or an oversized unit. You can check the fan motor speed to see if it's set too high before calling a service person to look at the unit.
  • Only the compressor runs - This could be caused by a number of issues, but they mostly involve wiring or issues with the fan motor. This problem is best handled by a pro.
