Geothermal systems provide efficient heating and cooling, but like any HVAC system, they can develop issues. While some minor repairs are manageable for homeowners, others require professional expertise. Understanding what you can and can’t fix yourself helps maintain system efficiency and avoid costly damage. Here’s a guide to DIY geothermal repairs in Baltimore, MD.
1. Changing Air Filters
Geothermal systems use air filters that need regular replacement to maintain airflow. Dirty filters reduce efficiency and strain the system. Check and replace filters every one to three months.
2. Resetting the System
If your geothermal unit stops working, try resetting it using the thermostat or breaker. Power surges and minor system errors can cause temporary shutdowns. A simple reset often restores normal operation.
3. Checking for Leaks
Inspect visible pipes and connections for leaks or condensation buildup. Small leaks in above-ground components may be fixed with sealants. However, underground loop leaks require professional repair.
4. Cleaning Coils and Fans
Dust and debris can accumulate on coils and fans, reducing system efficiency. Turn off the power and gently clean components with a soft brush or vacuum. Avoid using excessive force to prevent damage.
5. Avoiding Refrigerant and Electrical Repairs
Geothermal systems rely on refrigerant and electrical components that require specialized tools and expertise. Handling these yourself can lead to serious safety hazards. Always call a licensed technician for refrigerant or wiring issues.
Some geothermal system repairs are simple DIY fixes, but complex issues require professional intervention. Attempting advanced repairs can lead to higher costs and system failure.
