10 Most Common Heating Issues

technician fixing a furnace Midwest winters demand a reliable heating system. Whether you rely on a furnace, heat pump, or boiler, unexpected problems are an inconvenience; some are easy to fix, others require professional care for a lasting solution. A+ Derr Heating & Cooling is here to guide you in understanding and addressing common heating problems. We’ll highlight 10 common heating issues, their causes, and solutions to keep your home cozy. Let’s dive in.

Heating System Won’t Turn On

If your heating system won’t start, the problem might be as simple as a tripped circuit breaker, loose furnace panel, or a thermostat issue. If the breaker is fine and the thermostat is set correctly, the issue may be a faulty control board or transformer. If you’ve inspected accessible parts and don’t notice anything, call in an expert for a closer look.

Inconsistent or No Heating

Uneven heating or cold spots often result from dirty filters, blocked vents, or duct leaks. In some cases, poorly insulated rooms can also add to the problem. Clearing obstructions and replacing filters are simple fixes, but leaky ductwork or imbalances typically require professional attention.

Blows Cold Air Instead of Heat

A heater blowing cold air could have a thermostat set incorrectly, a pilot light that’s out, or malfunctioning heating elements. For gas systems, reigniting the pilot light might do the trick, but if the system still won’t heat, it’s time for a professional diagnosis, since the issue could stem from more complex issues like a broken ignitor or improper gas flow.

Frequent Cycling (Short-Cycling)

Short-cycling, where your heating system frequently turns on and off, wastes energy and stresses components. It’s often caused by clogged air filters, poorly placed thermostats, or oversized systems. Replacing filters can help, but persistent issues may need professional evaluation to resolve mechanical or sizing problems.

High Energy Bills

A sudden spike in energy bills can point to an inefficient heating system. Again, culprits range from clogged filters to dirty ducts or outdated equipment. Regular maintenance, like filter changes and sealing visible duct leaks, can help maintain efficiency. If your system is old, upgrading to a modern, energy-efficient model may be a wise investment.

Unusual Noises

Banging, rattling, or whistling sounds from your heater often point to mechanical issues. The cause could be loose parts, dirty burners, or restricted airflow. Tightening screws or replacing air filters may resolve some noises, but if weird sounds persist, they should be addressed by an HVAC technician.

Pilot Light or Ignitor Problems

For gas furnaces, the pilot light or ignitor helps control heat production. Dirt or debris buildup, faulty thermocouples, or drafts can extinguish the pilot or disrupt the ignition process. You might try relighting the pilot light, but if that doesn’t resolve the issue, call a technician to inspect the system.

Thermostat Isn’t Working

A thermostat misreading temperatures or failing to respond will disrupt your entire heating system. Dead batteries, poor wiring, or calibration errors are often to blame. Replacing batteries may resolve the issue, but wiring and calibration should be left to a trained technician to ensure safety and comfort.

Low or No Airflow

Weak airflow through vents usually indicates a clogged filter, blocked ducts, or blower motor problem. Where possible, try replacing filters and clearing visible obstructions to restore airflow. If things persist, a pro can inspect the motor or ducts and identify the root source of the problem.

Carbon Monoxide Concerns

Carbon monoxide (CO) leaks from a cracked heat exchanger or blocked vents are a major safety concern. They can induce dizziness, headaches, or alarms from a CO detector. If you suspect a leak, immediately leave the house and call for emergency assistance.
