Understanding these problems can help you identify when a DIY solution is possible or when it's time to call in the experts at Klee's Climate Control.

Dirty Filters

• Cause: Clogged air filters restrict airflow, forcing the furnace to work harder. This can lead to overheating and automatic shutdowns.
• Fix: Regularly replace or clean your furnace's air filters every 1-3 months to ensure efficient operation.

Wear and Tear

• Cause: Over time, components of your furnace wear out, affecting its ability to heat your home effectively.
• Fix: Schedule annual maintenance with us to keep your furnace in top condition and replace worn parts before they cause breakdowns.

Ignition or Pilot Control Issues

• Cause: A faulty ignition or pilot can make it difficult to heat a home. This could be due to a malfunctioning ignition system or a dirty pilot light.
• Fix: For newer furnaces, resetting the ignition might help. For older models, cleaning the pilot light or calling a professional for furnace repair may be necessary.

Malfunctioning Thermostat

• Cause: A faulty thermostat can lead to problems with the fan or comfort levels.
• Fix: Check the thermostat's batteries and settings. Sometimes, simply replacing the batteries or adjusting the settings resolves the issue.

Insufficient Maintenance

• Cause: Neglecting routine maintenance can lead to unexpected failures and inefficient performance.
• Fix: Enroll in a maintenance plan with Klee's Climate Control to ensure your furnace operates efficiently year-round.

Continuous Running Blower

• Cause: A blower that won't stop running could indicate a problem with the limit switch.
• Fix: The limit switch may need adjustment or replacement by a furnace repair technician in Mesa, AZ.

Noisy Furnace

• Cause: Rumbling, squeaking, or banging sounds can signal airflow reductions, a clogged burner, or mechanical issues.
• Fix: An inspection by our technician can identify and resolve the source of the noise.

Frequent Cycling

• Cause: Cycling between the on and off modes too frequently could be caused by a bad thermostat setting, improper airflow, or a clogged filter.
• Fix: Check the filter and thermostat. If the problem persists, professional furnace repair may be needed.

The Furnace Doesn’t Heat at All

• Cause: This could be due to several issues, including problems with the power, gas, thermostat settings, or pilot light.
• Fix: Ensure the furnace is powered, the thermostat is set correctly, and the pilot light is lit. If these don’t work, call Klee's Climate Control for assistance.

The Furnace Heats Poorly

• Cause: Insufficient heat could result from a clogged filter, improper gas supply, or incorrect ductwork.
