4 Possible Causes of Your Geothermal System Issues in Midland, NC

Geothermal systems make both heating and cooling your home more efficient in Midland, NC. However, like any HVAC system, over time, they may have a problem. Here are the top four possible causes of geothermal system issues you may encounter.

1. Circulating System Leaks

Your system must be able to circulate the refrigerant or water to continue heating or cooling your home. A leak anywhere in the system means there’s not enough of the circulating medium to absorb and transfer the needed heat.

A leak will make your home uncomfortable with improperly conditioned air coming from your vents. You may also notice wet or muddy areas in your yard, even if it hasn’t rained recently. A professional technician will inject a special dye into the system to find the leak’s location.

2. Inadequate Ground Loop Pressure

In order to transfer the heart appropriately, the refrigerant or water running through the ground loop must maintain a certain pressure. If the pressure drops, you will experience inadequate heating and cooling inside. Not only will the air not feel properly conditioned but your system will have longer run cycles.

As your system runs and ages, it may require more fluid to fill it even without leaks. A technician will check your system’s pressure and will recharge it to keep it at its optimal level.

3. Dirty Air Filter

There’s so much focus on geothermal-specific problems that you may forget about the problems around every HVAC system. The most often neglected one is the air filter. You’ll feel less air coming from your vents when you have clogged filters.

For a standard 1-inch filter, plan to replace it about every 90 days with average air quality. However, check it every month to catch it early, and gently vacuum the intake side to extend its life.

4. Mechanical Problems

Aside from a dirty air filter, you may encounter some mechanical problems that will prevent your system from operating properly. The symptoms of a mechanical failure may include:

  • Unusual and loud sounds
  • Low air volume
  • Improperly conditioned air
  • Long or short cycle lengths

These problems include a bad circulating fan motor, a faulty capacitor or contractor or even a clogged condensate drain. The best way to stay on top of these is to stay current on your routine HVAC maintenance.

Make sure your geothermal system is running properly by taking care of small problems quickly. Call to schedule your geothermal service with one of the experts at Dulin Mechanical Services, Inc today.
