5 Things to Check If Your Furnace Isn't Working after Des Moines' Recent Blizzard
As the residents of Des Moines and surrounding areas reel from the recent blizzard and significant snowfall, many homeowners are faced with the challenge of a malfunctioning furnace. In such extreme weather conditions, having a reliable heating system is more crucial than ever. Before you call a professional, there are a few things you can check if your furnace isn't working. Here's a guide to help you troubleshoot during these challenging winter conditions.
1. Check the Thermostat
Ensuring Proper Settings and Power
First, verify that your thermostat is set to "heat" mode and that the temperature setting is high enough to trigger the furnace. Sometimes, power surges or battery issues can reset or turn off thermostats. Ensure your thermostat has power, and if it's battery-operated, consider replacing the batteries.
2. Inspect the Furnace Filter
Clearing the Path for Warm Air
A clogged furnace filter can restrict airflow and cause your heating system to struggle or shut down. Check your furnace filter and replace it if it's dirty. This simple step can be particularly crucial after a blizzard, as the increased usage of your furnace may accelerate filter clogging.
3. Examine the Furnace Switch and Circuit Breaker
Restoring Power to the System
Sometimes, the furnace switch (usually located on or near the furnace) can accidentally be turned off. Ensure that this switch is on. Additionally, check your home's circuit breaker or fuse box to ensure the furnace hasn’t tripped a breaker or blown a fuse, a common issue during heavy snowfall and blizzards due to increased electrical demands.
4. Inspect the Furnace Vents
Preventing Blockages from Snow and Ice
The blizzard may have caused snow and ice to block your furnace's vents outside your home. A blocked vent can cause the furnace to shut off as a safety measure. Carefully clear any snow or ice from around these vents to ensure proper venting.
5. Evaluate the Furnace's Pilot Light or Ignition
Ensuring the Flame is Lit
For older furnaces with a pilot light, check if the pilot light is out. If so, follow your furnace's instructions to relight it safely. For newer furnaces with electronic ignition, a reset may be necessary. Refer to your furnace manual for instructions on how to reset the ignition system.
Conclusion
While these checks can resolve some common furnace issues, it's important to recognize when to call a professional. If your furnace still isn’t working after performing these checks, or if you’re uncomfortable performing any of these steps, contact a qualified HVAC technician. In the aftermath of a blizzard, prompt and efficient furnace repair is critical for the safety and comfort of your home. Remember, regular furnace maintenance can prevent many of these issues and is key to ensuring your furnace can withstand the challenges of extreme winter weather in Des Moines. Stay warm and safe this winter!
