GEOTHERMAL HEAT PUMPS

How does your geothermal system actually work?

A geothermal heat pump moves heat between your home and the ground through a buried loop of pipe. The ground stays at a much steadier temperature than outdoor air, so the system does not have to work as hard in a heat wave or a cold snap.

WHAT TO LOOK FOR

Signs you might notice.

Loop pressure or flow that has changed
Auxiliary heat running more than it used to
Equipment approaching 20+ years old

WHAT WE DO ABOUT IT

We service the loop side and the air side, measure performance, and give honest repair-or-replace numbers when the indoor unit nears end of life.
