When the temperatures dip in Baton Rouge, having a dependable heating system is more than just a luxury—it’s a necessity. But what happens when your heater stops working properly? Before panic sets in, it’s helpful to understand the most common heating problems and how to troubleshoot them.
At Shield Mechanical, we’ve helped countless homeowners in Ascension Parish, Livingston Parish, and beyond stay warm by addressing these exact issues.
1. No Heat Coming from the Vents
If your heater is running but there’s no warm air coming out, it could be a simple fix—or a sign of a larger issue. First, check your thermostat settings and make sure it's on “heat” mode. Then verify that the temperature is set higher than the current room temperature. If that checks out, inspect your air filter—clogged filters can restrict airflow and make your system work harder than necessary.
Still cold? The problem might be with the pilot light, gas supply, or ignition system. These components should be checked and repaired by a licensed HVAC technician.
2. Uneven Heating Throughout the House
Do some rooms feel like a sauna while others are freezing? Uneven heating is a common problem in older Baton Rouge homes, especially those with outdated ductwork or poorly sized systems. Make sure vents are open and unblocked in all rooms. If the issue persists, you may have a problem with your ductwork, insulation, or zoning system.
Our team at Shield Mechanical can assess your entire setup and offer tailored solutions that ensure consistent warmth in every room.
3. Strange Noises or Odors
If your heater makes banging, rattling, or squealing sounds, it’s time to call in a professional. These noises can indicate anything from loose parts to a failing blower motor. Similarly, musty or burning smells coming from your vents may suggest mold buildup, electrical issues, or dust burning off after months of inactivity.
Don’t ignore unusual sounds or odors—these are your system’s way of telling you something’s wrong.
4. Short Cycling or Constant Running
Short cycling—when your heater turns on and off rapidly—is inefficient and stressful on your system. It’s often caused by dirty filters, malfunctioning thermostats, or overheating components. On the other hand, if your system never seems to shut off, it might be struggling to reach the set temperature due to a faulty thermostat or insufficient insulation.
Both problems can drive up your energy bills and shorten the lifespan of your equipment.
