Why is my geothermal not blowing cold air?

If your geothermal is not cooling your home, it may have dirty air filters. Dirty filters lower the efficiency of your HVAC system. They allow in dirt, dust and other biological contaminants that restrict proper airflow in your house.

How do you troubleshoot a geothermal heat pump?

Geothermal Heat Pump Problems? Troubleshooting Tips

  1. Check the power supply. If the system won’t run, check your home’s electrical panel for tripped circuits.
  2. Check the water supply.
  3. Inspect the air filter.
  4. Check loop pressure.

Why is my geothermal heat not working?

Check the air filter and coils to be sure they are not dirty. If air cannot flow through the system, the heat pump can’t do its job. Clean the coils, replace the filter, and if the unit is outside, clear away any debris or plants that could be inhibiting air flow.

What does purge mean on a geothermal?

“Purging” is the process of clearing an air conditioner’s (AC’s) unit’s internal lines and hoses. This is frequently done before recharging freon but. many newer model AC units, such as Honeywell units, purge the system on startup.

Why does my geothermal blowing cold air?

If your geothermal HVAC system is blowing cold air on a frigid day, the emergency heating system may have an electrical problem, such as a malfunctioning capacitor.

How do you fix a low pressure lockout?

A low pressure alarm indicates the controller has received an open signal from the normally closed low pressure switch circuit. Three active alarms within one hour will trigger a compressor lockout to protect the refrigerant circuit. The lockout can be cleared by power cycling the controller.

What can go wrong with ground source heatpump?

Typical problems could include low refrigerant levels, scale or fouling of the heat exchanger or a problem with the reversing valve. Warm air not warm enough. A common cause of this problem is that the flowrate of the air through the system is too high.

What can go wrong with geothermal systems?

However, you should stay alert for common geothermal heat pump problems, including leaks, water contamination, and ductwork issues.

Why is my geothermal blowing cold air?

What temp does geothermal stop working?

Geothermal offers many benefits over traditional air-source or combustion-type heating systems. Using the in-ground loop field, a geothermal unit (or “ground-source heat pump”) is able to pull heat energy from the 45°F-70°F earth to heat your home at efficiencies of over 400%.
