Troubleshooting Your Geothermal HVAC System in Maumelle, AR

Geothermal HVAC systems provide ultra-efficient heating and cooling in Maumelle, AR. However, they’re not immune to occasional malfunctions, like any other type of HVAC system. Here’s how to troubleshoot your geothermal HVAC system when it isn’t working properly.

Check Your Air Filter

If your geothermal system turns on but isn’t supplying adequate airflow throughout your home, its air filter may need replacement. Most systems require a new filter every 30 to 90 days as part of their ongoing maintenance. If yours gets too dirty and you don’t replace it, it will restrict airflow through the system.

Check Your Thermostat

Check your thermostat settings if your geothermal HVAC system isn’t turning on when you think it should. First, check whether your thermostat is in heating or cooling mode. If someone inadvertently switched it to the wrong setting, it can explain the behavior you’re seeing.

Also, you may want to check your home’s temperature with a separate thermometer. Your thermostat may misread your home’s temperatures, particularly if it’s near windows, doors or heat-generating appliances. You may also have a mis-calibrated thermostat, in which case you’ll need a professional to fix the issue.

Check Your Loop Pump

Check your loop pump if your geothermal system is blowing air but not as cold or warm as you expect. It’s the part that circulates the working fluid through your system’s ground loops. If the pump fails, your system won’t function as expected.

You can usually tell if your pump turns on by the telltale hum it emits while running. You may need to replace it if it’s making any unusual noises or not running at all. Otherwise, the unusual noises may indicate a pressure issue in your ground loop.
