Top 5 Furnace Complaints this time of year:
🔥 Furnace won’t turn on – After months of sitting idle, many units fail to start due to a tripped breaker, dirty flame sensor, or faulty thermostat.
🔥 Weak or no heat – Common causes include clogged filters, blocked vents, or failing igniters that prevent full heating cycles.
🔥 Strange noises or smells – Rattling, banging, or musty/burning odors often point to loose parts, dust buildup, or overheating components.
🔥 Frequent cycling on and off – Usually caused by dirty filters, bad sensors, or thermostat calibration issues.
🔥 Cold spots or uneven heating – Resulting from duct leaks, poor airflow, or malfunctioning blower motors.

If you’re experiencing any of these, call Haertel Heating today!
