Air Conditioning Maintenance Needs Of A Geothermal HVAC System

Maintaining your AC is important if you want to have cooling all summer, and if you have a geothermal AC, there will be some specific maintenance tasks to do. You want to make sure that the fluids in the loop are clean and freely flowing. When you do AC maintenance, you will want to check some of the components of your geothermal HVAC, such as the heated hose. Here are some of the specific maintenance needs that a geothermal air conditioning system will need:

1. Flushing the Ground Loop to Remove Contaminates

Geothermal HVAC systems have a loop of pipes that circulate water or liquid to provide a special type of heat exchanger. The geothermal loop may be an open loop if it takes water from an open well, or a closed loop if it is a cold circuit, which may also include additives to prevent freezing of the water, aid in heat exchange and allow the liquid to flow more freely. Just like with other types of pipes, buildup of grime and debris can cause blockages or reduce the flow of the circuit. Have the system flushed and cleaned occasionally to ensure your geothermal HVAC is working smoothly.

2. Cleaning the Geothermal Coils to Remove Dirt and Dust

With geothermal AC, there are additional coils that aid in cooling the air to reduce energy consumption. Make sure that the coils of the geothermal heat exchanger are clean. The geothermal components may be separate from the conventional air conditioning coils, so when you clean them, make sure you clean all the coils and not just one or the other.

3. Inspecting Water Pump and Geothermal Components

Water pumps are also an additional component of a geothermal HVAC system. The pump is what circulates water from the ground loop, to the system and back; acting as a heat exchanger. Just like with other types of water pumps, like those used for water wells, your geothermal pump will need maintenance to ensure your system is working properly. When you do seasonal maintenance to your AC, also inspect the pump for signs of any problems that need to be addressed. When the water pump is not working, your geothermal HVAC will not be working properly, so it is important to have any repairs done.

When you have a geothermal HVAC system, there is going to be some maintenance that needs to be done when you are using your cooling system. Contact an HVAC repair service to help with the maintenance your geothermal air conditioning.
