Furnace Not Keeping Up with the Cold? Here’s What to Do

Published by Luke Weiden

Experiencing a furnace failure during Chicago’s harsh winters can be daunting. When your heating system struggles to maintain warmth, it’s essential to quickly identify and address the issue. In this blog post, we identify what to do if your furnace stops working in winter. If following these steps fails, contact us for emergency heating repair.

Understanding Common Furnace Issues

Several factors can cause your furnace to underperform in cold weather:

  • Thermostat Malfunctions: An incorrectly set or faulty thermostat can disrupt your home’s heating.
  • Improper Furnace Size: A furnace that’s too small may not effectively heat your space during extreme cold.
  • Clogged Air Filters: Dirty air filters restrict airflow, forcing the furnace to work harder.
  • Ignition Problems: Issues with the pilot light or electronic ignition can prevent the furnace from producing heat.
  • Poor Insulation: Inadequate insulation allows heat to escape, making it challenging to maintain desired temperatures.

Immediate Troubleshooting Steps

If your furnace isn’t keeping up with the cold, consider the following actions:

  1. Replace or Clean Air Filters: Dirty filters can impede airflow. Regular air filter replacement can enhance efficiency.
  2. Inspect the Thermostat: Ensure it’s set to “heat” and the temperature is appropriately adjusted. Replace batteries if necessary.
  3. Examine the Power Source: Check your circuit breaker for any tripped switches and reset them.
  4. Assess the Pilot Light or Ignition System: For gas furnaces, verify that the pilot light is lit. If it’s out, consult your furnace’s manual for relighting instructions.
  5. Evaluate Home Insulation: Seal drafts around windows and doors and consider adding insulation to retain heat.

When to Seek Professional Assistance

While some issues can be resolved independently, certain situations require expert intervention:

  • Persistent Heating Problems: If troubleshooting doesn’t restore warmth, there may be underlying issues.
  • Unusual Noises: Sounds like banging or screeching could indicate mechanical problems.
  • Frequent Cycling: If your furnace turns on and off repeatedly, it may signal a malfunction.

In such cases, it’s advisable to contact a certified HVAC technician to diagnose and rectify the problem.

Preventative Measures for Optimal Performance

To ensure your furnace operates efficiently throughout the winter:

  • Schedule Regular Maintenance: Regular furnace maintenance can identify and address potential issues before they escalate.
  • Upgrade Your Thermostat: Modern, programmable thermostats offer precise control and can enhance energy efficiency.
  • Maintain Clean Filters: Regularly replacing or cleaning filters promotes better airflow and system performance.

By proactively managing your heating system, you can maintain a comfortable home environment even during Chicago’s coldest months.
