7 Tips for Maintaining a Geothermal Heating System 7 Tips for Maintaining a Geothermal Heating System

A geothermal heating system, while initially expensive to install, is energy efficiant and easy to maintain. Maintenance is key in keeping the system working properly. Specific instructions can be found in an owner's manual, but here are a few basic tips. 

Tip 1: Keep an eye on the thermostat. 

The thermostat should be checked at least once a month. If it uses batteries, keep them fresh to ensure that the thermostat works at its full potential. 

Tip 2: Air filters

There are several air filters available. These fall into two basic categories, disposable and non-disposable. Disposable filters should be thrown away after their first use. Do not try to remove the dust or reverse the filter. That will only cause dust to get further into the unit. Different types of disposable filters have different lifespans. Refer to the owner's manual or filter packaging. If you have someone with allergies, pets, or a high level of activity you will need to change the filters more frequently. You can clean non-disposable filters. Be sure you check them every few months and clean them according to the manufacturer's instructions. Like disposable filters, you should not reverse the filter instead of cleaning it. 

Tip 3: Condensation Pans

Condensation pans should be checked at least once a year, preferably during heavy cooling periods. You should also check the drain pain if the drain light turns on. Drain any excess fluids, clear any clogs and check for algae. If you find algae you should have the system professionally treated. There are ways to prevent mold forever. During your yearly check, mix a capful of chlorine bleach in a quart of water and pour it down the drain. 

Tip 4: Check the Ducts

Loose ducts can cause future problems for your system. In order to find and stop any problems you should check the ducts at least once a year. Find every visible duct and check that they are all connected. You should also examine the registers in every room. Ensure that they are open and have adequate airflow. 

Tip 5: LED lights

Your unit may have LED lights that show the status of different parts of the system. If you have any problems, check these lights first. They will give you a general idea as to where to find the problem. There should be a guide to the lights' meanings in the owner's manual. The manual will also tell you the potential problems in each system and how to fix them. 

Tip 6: Accessories

This may seem obvious, but you should occasionally check your system's visible accessories. These accessories play a role in how well your system works and should not be ignored. 

Tip 7: Sounds

Finally, if you cannot find anything wrong with your system, listen to it. There may be parts underground or in your walls that need attention. If your system begins to act unusually and is making strange sounds it may be time to call in a contractor to look at the unit. They will be able to find any hidden problems.
