Dealing with a heater that blows cold air can be frustrating, especially during the chilly months in Los Angeles. Addressing the issue quickly can prevent costly repairs or replacements. Here are common reasons for this problem and tips on what to check.
Common Issues and Solutions
1. Thermostat Settings
A common culprit behind cold air is incorrect thermostat settings. Ensure your thermostat is set to ‘auto’ instead of ‘on.’ In the ‘on’ mode, the fan continues to run even when the heater isn’t producing warm air. Adjusting this setting could immediately fix the issue.

2. Pilot Light Problems
For gas heaters, a pilot light that has gone out will prevent the system from producing heat. Relight the pilot light if needed and check that the gas valve is open. If your home has an electric furnace, inspect the connections to ensure it’s receiving adequate power.

3. Clogged Air Filters
Dirty or clogged air filters can restrict airflow, causing the heater to overheat and shut down its burners as a safety measure. Inspect your filters and clean them monthly, replacing them every three months to ensure optimal airflow.
Routine maintenance is crucial for system efficiency. Check out our HVAC Maintenance Services to keep your heater in top shape.
4. Duct Leaks
Leaking ducts can make it seem like your heater is malfunctioning. Cold air from crawl spaces or attics can seep into your home, reducing the warmth from your heater. Inspect your ductwork for holes or cracks and seal any leaks.
If the issue persists, calling a professional may be necessary. Remember, some HVAC problems are better left to experts to ensure safety and efficiency.
