What Kind of Repairs Should I Expect for a Geothermal System?

One of the major advantages of having installation of a geothermal heat pump in your home is the incredible longevity of these systems. According to the U.S. Department of Energy, the indoor elements of a geothermal system can last 20+ years, while the in-ground coils (the most expensive part of installation) can last 50+ years. That’s an enormous amount of time for you to get the full benefits of the energy-efficient performance of geothermal power.

However, durability doesn’t mean invincibility, so you can expect occasional repair needs for your ground source heat pump. Here are some repairs you might encounter from your system. Call on experts in geothermal repair in Pooler, GA when you need assistance: look to AAction Air, where our technicians are on-call 24-hours a day.

Some geothermal repair needs you might have

  • Leaks in the pipes: The underground pipes that run through your property, carrying the crucial water and antifreeze mixture needed for heat exchange, rarely develop leaks (unless they were poorly installed). But accidents from extreme weather conditions, construction, or age can still lead to leaking, and this will cause your indoor heat pump to lose efficiency. A technician can put a dye into your system and then trace where it emerges on the surface to find leaks. This allows the least amount of excavating necessary for repairs.
  • Broken reversing valve: If your ground source heat pump seems to only provide heat when need cooling, or vice versa, the problem could be refrigerant leaking… but it could also be a failed reversing valve, which means the refrigerant going through the heat pump will only go one direction and therefore you cannot switch between modes. Thankfully, this repair requires no digging: the technician needs only open up your indoor unit and replace the broken reversing valve.
  • Replacing the indoor heat pump: We mentioned above that the indoor unit has a lower life-expectancy than the in-ground elements. Normally, “replacing the heat pump” for an air-source heat pump wouldn’t count as a repair, it would be a full new heat pump installation. With geothermal, however, the underground coils will remain in place, and the unit that contains the air handler, compressor, and reversing valve is replaced if it has worn down too much. You can expect this repair to happen eventually—but with proper annual maintenance it should be many years off.

Make sure you take excellent care of your geothermal heat pump so that the repairs you do need will be few and far between. When it is time for geothermal repair in Pooler, GA, contact our experts at AAction Air.
