The temperature has dropped, and your furnace has gone silent. For homeowners in Lubbock, a furnace failure on a cold day is more than just an inconvenience—it’s a serious problem. Before you panic, there are a few simple troubleshooting steps you can take that might get your system back online. If those don’t work, knowing what to do next is crucial.
At Nugent Mechanical, we’re here to help you stay warm and safe. Here’s a quick guide on what to do if your furnace stops working.
Step 1: Check the Basics First
Sometimes, a furnace problem isn’t a major mechanical failure but a simple issue you can fix yourself.
- Thermostat: Check your thermostat’s setting. Make sure it’s set to “heat” and that the temperature is set at least 5 degrees higher than the current room temperature. Also, check to see if the batteries are dead.
- Power Switch: Look for a light switch near your furnace. It often looks just like a regular light switch but is typically on its own and may have a red cover. Make sure it’s in the “on” position. It’s not uncommon for this switch to be accidentally flipped.
- Circuit Breaker: Go to your electrical panel (breaker box). A tripped breaker is a common culprit. Look for a breaker that is in the “off” position or is between “on” and “off.” Flip it completely off and then back on to reset it.
- Air Filter: A clogged air filter can restrict airflow, causing your furnace to overheat and shut down. Check your filter and replace it if it’s dirty. This is a crucial, easy fix that prevents many furnace issues.
- Gas Valve: For gas furnaces, ensure the gas valve on the supply line is in the “on” position. It should be parallel with the pipe, not perpendicular to it.
Step 2: What to Do If Troubleshooting Fails
If you’ve checked all the basics and your furnace is still not working, it’s time to call a professional. Do not attempt to make a major repair yourself. Working on a furnace can be dangerous due to gas lines, electrical components, and the risk of carbon monoxide.
- Turn the System Off: Turn the power switch near your furnace to the “off” position to prevent any further damage.
- Stay Warm and Safe: If the temperatures are dangerously low, consider staying with family or a friend, or using alternative safe heating methods like a space heater (use caution).
- Call a Professional: Contact a reputable HVAC company like Nugent Mechanical. Be prepared to describe the problem and what you’ve already checked. This will help the technician diagnose the issue more quickly.
