🔥 Common Heating Problems & How to Fix Them | Orange County Furnace Guide

When the cooler nights hit Orange County, the last thing you want is a heater that isn’t working. If your furnace or heating system is not blowing hot air or refuses to turn on, the problem could be easier to fix than you think.

At GoTech Air Conditioning & Heating, we service all major heating systems, from gas furnaces to heat pumps. Here are the most common heating problems we see—and what you can do about them.

⚠️ Top Heating Problems Homeowners Face

1. Furnace Not Blowing Hot Air

If your system is running but the air isn’t warm, it could be:

  • A dirty air filter blocking airflow

  • Incorrect thermostat settings (set to “heat” mode and higher than room temp)

  • A failing blower motor that can’t push air properly

2. Pilot Light or Flame Sensor Issues

For gas furnaces, a faulty flame sensor or dirty pilot assembly can shut down the system. If the flame sensor is covered in soot or corrosion, it may not detect the flame—causing the furnace to turn off for safety.

3. Gas Valve Problems

If your furnace isn’t igniting at all, a gas valve failure could be the culprit. Since this involves your gas line, it’s best handled by a licensed HVAC technician.

4. Blower Problems

If you hear the furnace running but no air is coming through the vents, the blower motor or control board may be failing. This requires professional testing and repair.

5. Thermostat Malfunctions

Sometimes the issue isn’t the furnace at all. A faulty or old thermostat can prevent the system from kicking on—or cause short cycling. Upgrading to a smart thermostat can solve control issues and improve efficiency.

🛠️ DIY Checks Before Calling a Pro

  • Replace or clean your air filter

  • Check thermostat batteries and settings

  • Inspect the furnace switch and circuit breaker

  • Make sure your gas supply is turned on

If the problem continues, it’s time for a professional inspection.
