Geothermal heat pumps require less maintenance than gas, oil-fueled systems, and air-to-water heat pumps.
Here’s a quick look at why “low maintenance” applies to geothermal heat pumps.
- Fewer moving parts – Geothermal heat pumps use fewer moving parts compared to conventional heating systems. Fewer moving parts means less wear and tear, without compromising efficiency.
- Rust-free components – Made of PEX pipe, the outdoor/underground components of geothermal systems are unsusceptible to rust and corrosion that shorten the lives of outdoor compressors in traditional air conditioner and modern air source heat pumps.
- Stable operating conditions – Geothermal systems operate in relatively stable temperature conditions. The ground temperature several feet below the surface remains consistent throughout the year, which means the system doesn’t experience the thermal stress and extreme temperature fluctuations that conventional systems experience.
- No combustion process – Conventional heating systems burn fuel. The resulting soot, ash, and other byproducts often necessitate regular cleaning and maintenance. Rather than burning fuel to create energy, geothermal systems transfer energy in the form of heat from one place to another.
- Reduced electrical load – A geothermal heat pump doesn’t have to work as hard as an air-source heat pump does, reducing wear.
These factors also lead to a longer lifespan for your geothermal system. An underground loop can last 50 years or more. Geothermal heat pumps can last between 20 and 25 years.
Maintenance to Expect
What maintenance will your geothermal system require? Here’s a rundown:
If your unit has an air handler, replace the filter every 1-3 months. Radiant heating requires no filter change.
An annual inspection of your system by a professional is a good idea. This should include:
- Checking the unit’s refrigerant level, coils, and electrical connections.
- Checking and calibrating your thermostat.
- Checking the pressure in your ground loops to ensure efficient heat transfer.
Additional Tips
- Monitor your energy bills and system performance. Unusual increases in energy consumption can indicate a problem.
- Pay attention to any unusual sounds coming from the heat pump or ductwork, as these can signal maintenance needs.
While the day of “no maintenance” home heating and cooling is yet to come, geothermal systems are pointed in the right direction. Reduced maintenance costs play an important part in system savings and convenience.
