Geothermal Longevity is Real

You’re interested in ground source technology, but you don’t know anything about geothermal longevity. Will these units last for years or will you be lucky if you get a few months of operation?


Geothermal Longevity Extends for Decades


If you make a substantial financial investment in technology for your home, you want to be certain that investment is going to pay off. Ideally, it will pay off and keep paying for years to come.


When it comes to investing in a new heating, ventilating and air conditioning system for your home, it doesn’t matter how energy efficient the design is if the machine itself is poorly made and breaks down after only a few short years of operation. Choose geothermal and you won’t have to worry. 


In addition to their unrivaled energy efficiency, geothermal heat pumps are among the longest lasting HVAC systems available. A geothermal heat pump uses the ground as a heat reservoir. This means the Earth itself protects substantial portions of the unit. Such protection prevents a lot of wear-and-tear a traditional outside unit outside would sustain. Years of sun damage and harsh weather corrosion will negatively affect operation. Geothermal heat pumps avoid that altogether.


As a matter of fact, geothermal heat pumps are so durable the U.S. Department of Energy estimates the internal components will typically last up to 25 years. Even better, the current best estimate for a ground loop is over 50 years!


Of course, a ground loop could last much longer than that. We can’t say for sure, since there hasn’t been enough decades since ground source tech was invented to adequately test it. At the very least, you can reliable estimate a half century of operation from your ground loop, which is far more than can be said for a conventional HVAC coil.
