My Geothermal System Stopped Cooling: What to Do Next?


Geothermal systems save power and feel like they last forever, so it’s no wonder you made the switch. But it doesn’t mean geothermal units are without faults, and sometimes that means no cooling. Don’t worry—there’s a fix for that.

With your geothermal not cooling in Fairfield, there are a few things that you can do to fix the issue. If not, you’ll need to hire a professional to come and take a look, but let’s do everything we can to prevent that from happening first.

Check the Thermostat First

Before you do anything else, check the thermostat. We know, it sounds simple, but sometimes we all overthink a problem when the answer is right in front of us.

Is your thermostat working properly? Is it detecting the right temperature? If it thinks that the room temperature is lower than it actually is, it could be telling your geothermal system to stop cooling before it’s supposed to.

Next, Replace Your Air Filter

Airflow is important in any HVAC system. Without proper airflow, your geothermal system has to work harder to heat and cool your home. In fact, if it has to work extra hard, that might be the reason that it’s not cooling in the first place.

If You Can Access It, Check Your Ductwork

Any ductwork that you can access should be inspected to see if there’s tears, holes, or just complete disconnects causing problems. Sometimes ductwork runs through too much of your home (or in too small of spaces) for you to effectively investigate it.

In that case, a professional HVAC technician can inspect your ductwork for you to see if there are any problems. With advanced tools, they can locate issues faster than if you check your ductwork on your own.

It Could Be a Refrigerant Leak

While we don’t want this to be the case, it could be a refrigerant leak. When refrigerant leaks, it can cause serious health problems, which is why you should stop what you’re doing and call for emergency geothermal system repair if you see a leak.

This means that there’s a leak coming from the closed loop system in your geothermal unit. This may be able to be repaired, but the closed loop might have to be replaced depending on the extent of the damage.

When there isn’t enough refrigerant in the line, your geothermal system can freeze and cease operation. That might be what was preventing your unit from cooling your home the entire time.

By the time a leak reaches this level, there could already be a fair amount of damage. There’s a chance that refrigerant has impacted other parts of your system, so be prepared.

It May be Time to Call the Experts
