What Maintenance Does a Geothermal System Need?

Efficiency and reliability are hallmarks of a geothermal system. They are also known for their long lifespan. A primary benefit is that they require less maintenance than traditional heating and cooling systems. However, they still require some degree of maintenance. Protecting your investment and providing peak performance for decades is possible with a few essential upkeep tasks.

You can enjoy consistent comfort and savings by understanding the needs of your system. This guide covers the simple home tasks of a homeowner and the important professional services required to keep your system in optimal condition.

Key Maintenance Tasks for Homeowners

A technician should deal with most geothermal maintenance. However, there are a few important things you can do to support your system’s health. These simple steps are important for its day-to-day performance.

Regular Air Filter Replacement

Like a conventional furnace or air conditioner, your geothermal system’s indoor unit uses an air filter to capture dust, pollen, and other airborne particles. A clean filter is vital for your indoor air quality and the system’s functioning.

A clogged filter restricts airflow, forcing the fan motor to work harder and consume more energy. This strain can reduce efficiency and may eventually lead to component failure. We recommend checking your filter monthly and replacing it every one to three months, depending on your filter type and household factors like pets or allergies.

Keep the Indoor Unit and Vents Clear

Your geothermal system’s indoor unit needs adequate space for air to circulate. Avoid storing boxes, furniture, or other items directly around the unit. It’s a good practice to walk through your home periodically and keep all air vents and registers open and unobstructed.

The Importance of Professional Annual Maintenance

Your geothermal system’s core components, including the heat pump and underground loop field, are complex. Annual professional inspections are necessary to keep every part functioning correctly. A trained technician has the expertise to discover subtle issues before they become serious problems.

During a professional tune-up, our team performs a comprehensive system check. This proactive service is the best way to maintain reliability and efficiency. Regular geothermal system maintenance you get the most comfort from your system.

• Inspecting and cleaning indoor unit coils
• Checking and tightening electrical connections
• Lubricating motors and moving parts
• Inspecting the condensate drain
• Testing thermostat calibration and controls
• Measuring fan motor performance
• Checking for energy-wasting ductwork leaks

Inspecting the Geothermal Loop System

The buried ground loop is the center of your geothermal system and is responsible for transferring heat to and from the ground. This component is very durable, with a potential lifespan of over 50 years. While problems are rare, periodic checks are essential to confirm its integrity and performance.

Our technicians are experts in servicing all types of geothermal loops, from horizontal and vertical to pond loops. During an inspection, we focus on the key indicators of the loop field’s health.

Loop Pressure and Fluid Levels

The ground loop is a closed system containing a mixture of water and antifreeze that circulates continuously. A technician will check the pressure and flow rate of this fluid. If the pressure is low, it could indicate a leak somewhere in the system. We check that the loop is properly pressurized for optimal heat exchange.

Antifreeze and Water Solution Quality

Over time, the fluid inside the loop can degrade. During a maintenance visit, a technician will test the quality of the antifreeze solution. This ensures it still provides adequate freeze protection and that its pH levels are correct to prevent corrosion within the system’s components.

Why You Should Never Skip Geothermal Service

It can be tempting to skip maintenance on a system that seems to be running well. However, professional service is an investment in your home’s comfort and your system’s future. Regular tune-ups protect your system’s efficiency, prevent unexpected breakdowns, and help it reach its maximum lifespan.

Most manufacturers require proof of annual professional maintenance to keep the warranty valid. Skipping service could leave you responsible for the full cost of a major repair that would have otherwise been a covered benefit.
