Furnace Troubleshooting | Common Problems & Easy Solutions

When the chill of winter sets in, the last thing you want is a furnace that’s not up to the task. At RK Heating & Cooling, we understand the importance of a reliable heating system. Our expertise in furnace repair and furnace service in O’Fallon and St. Louis, MO ensures your home stays comfortable and warm all season long. In this guide, we’ll walk you through some common furnace problems and their easy solutions, empowering you with the knowledge to keep your heating system in top condition.

Inspect and Replace the Furnace Filter

A clogged or dirty filter is a common culprit behind furnace issues. It can restrict airflow, putting unnecessary strain on your furnace and potentially leading to more serious problems.

  • Check monthly: Regular inspections can prevent blockages and improve efficiency.
  • Replacement: If the filter looks dirty, replace it immediately to ensure optimal airflow and furnace operation.

Our team at RK Heating & Cooling recommends keeping a supply of the correct filter size on hand, making this routine maintenance task even easier for homeowners in O’Fallon and St. Louis.

Verify Thermostat Settings

An incorrectly set thermostat can cause your furnace to behave unpredictably. Make sure the thermostat is switched to “heat” mode and that the set temperature is above the current room temperature.

  • Battery check: Replace batteries annually or as needed.
  • Programming: Consider a programmable thermostat for automatic temperature adjustments, saving energy and enhancing comfort.

As specialists in furnace service in St. Louis, MO, we often find that simple thermostat adjustments can resolve many heating issues, avoiding the need for professional repairs.

Examine the Furnace Flame

The color of your furnace flame can be a strong indicator of its health. A healthy furnace flame is blue with possibly a small yellow tip, signifying complete combustion.

  • Yellow or orange flames: These colors could indicate a problem, such as the presence of rust, dirt, or even a gas leak.
  • Professional inspection: If the flame color is off, it’s time to call in RK Heating & Cooling for a thorough inspection and possible furnace repair in O’Fallon, MO.

Ensure the Front Panel Is Securely Fastened

Modern furnaces have safety switches that prevent the unit from operating if the front panel is not properly secured.

  • Check the panel: Make sure it’s tightly closed. Even a slightly ajar panel can trigger the safety switch, stopping the furnace from running.
  • Listen for clicks: A properly secured panel will typically make a distinct click sound, indicating the safety switch is engaged.

Maintain Open and Clear Vents and Registers

Keeping all vents and registers open and free from obstructions is crucial for maintaining an efficient and evenly heated home.

  • Regular Inspections: Periodically check to ensure that furniture, curtains, or rugs are not covering or blocking airflow through your vents and registers. This not only helps in distributing heat more evenly but also reduces the strain on your furnace, potentially extending its lifespan.
  • Clear Pathways: Make sure there’s a clear path for air to circulate freely in each room. This involves rearranging any items that might hinder air movement and ensuring vents are open and unobstructed.

By following these steps, you can enhance the efficiency of your heating system and enjoy a more comfortable environment in your home.
