Winter Furnace Guide: Troubleshooting Tips For a Warm and Cozy Home

Learn about troubleshooting tips to help keep your furnace running smoothly & your home comfortably heated during the winter season.

In winter, there's nothing quite like coming home to a warm and cozy house on a chilly day. But what happens if your furnace decides to act up, leaving you shivering in your own home? Don't worry, we've got you covered! In this blog post, we'll walk you through some troubleshooting tips to help you keep your furnace running smoothly and your home comfortably heated throughout the winter season.

1. Check the Thermostat:

Is your thermostat set to the desired temperature? It may sound obvious, but sometimes a simple adjustment can solve the problem. Ensure that the thermostat is set to "heat" mode and that the temperature setting is higher than the current room temperature. If the thermostat is battery-operated, replace the batteries to rule out any power issues.

2. Inspect the Air Filters:

Clogged air filters can hinder proper airflow and put unnecessary strain on your furnace. Take a moment to locate your air filters and check if they are dirty or clogged. If so, it's time for a replacement. Clean air filters not only improve the efficiency of your furnace but also enhance the air quality in your home.

3. Check the Condensate Drain:

In mid- and high-efficiency furnaces, a condensate drain is responsible for removing excess moisture that is produced during the heating process. If the condensate drain becomes clogged or blocked, it can lead to issues with your furnace's operation.

Signs of a clogged condensate drain include water pooling around the furnace or a shut-off safety feature that prevents the furnace from turning on.

To address this issue, it's best to contact a professional HVAC technician who can safely and effectively clear the condensate drain.

4. Check the Circuit Breaker:

A tripped circuit breaker can cause your furnace to stop working. Head over to your electrical panel and check if the breaker for your furnace is in the "on" position. If it has tripped, reset it and see if that resolves the issue. If the breaker continues to trip, it's recommended to consult an experienced HVAC technician.

5. Ignition Issues:

For furnaces with electronic ignitions, listen for the sound of the ignition system. If you don't hear a click or see a spark, there might be an issue with the ignition system that requires professional attention. One common component of electronic ignition systems is the hot surface igniter. This small, fragile part is responsible for igniting the gas in your furnace. Over time, it can become worn out or damaged, leading to ignition problems. If you suspect an issue with the hot surface igniter, we recommend that you reach out to a reliable HVAC company to inspect and replace it if necessary.

By following these troubleshooting tips, you can save yourself from the discomfort of a malfunctioning furnace during the winter months. However, if you've tried these steps and your furnace still isn't working properly, it's time to call in the experts. A professional HVAC technician from HVAC-Group can diagnose and resolve complex issues, ensuring your home stays warm and cozy all winter long.
