4 Reasons Why Your Furnace is Malfunctioning

You should be able to count on your furnace for reliable heating all winter long. Unfortunately, issues with the pilot light, filter, motor, and other various components can leave your system blowing cold air. Here are a few common causes behind malfunctioning heating systems in San Antonio, TX.

1. Dirty HVAC Filter

When your furnace filter fills with dust, hair, and grime, it prevents air from entering the heating system. Continuing to use a dirty air filter typically results in longer heating cycles and the motor overheating. You may also find your daily comfort decreasing as your utility costs increase.

2. Dirty Pilot Flame Sensor

Many older gas furnaces have pilot lights that are key to starting heating cycles. The flame sensor will detect if you have an active pilot that can ignite the fuel. A dirty or worn-out sensor won’t be able to perform effectively, resulting in system inefficiencies and potential safety concerns.

3. Thermostat Issues

Your heating system’s issues could also relate to an outdated thermostat. Thermostats act as the command center for your home’s heating and cooling system. Have a professional check for internal wiring issues or power concerns.

4. Leaking Ductwork

One of the biggest factors contributing to your home’s energy waste is likely your leaky ductwork. When heated air leaks out of existing cracks and holes, it forces your furnace to run longer to make up for it. This creates large amounts of internal strain that may lead to frequent heating repairs and a shorter lifespan.
