A gas furnace is highly efficient at heating a home in Moreno, California. But like any other appliance you depend on for comfort and convenience, it can experience problems. If your furnace starts malfunctioning in the middle of winter, it can cause distress and discomfort. Here are four warning signs that your gas furnace requires a professional repair:

Continuous Operation

The good news is that your furnace turns on. But the bad news is that it won’t turn off. If your furnace operates continually, it’s likely because it has a faulty limit switch. A professional service technician can replace it quickly.

Frequent Cycling

Frequent cycling wastes a lot of energy and strains your furnace. As a result, you end up with higher energy and repair bills. If your furnace turns on and off frequently, it’s probably because of a clogged filter or an incorrect thermostat setting. If fixing these issues doesn’t resolve the problem, you’ll need a professional to check your furnace’s airflow.

Yellow Pilot Light

We all know the dangers of excess carbon monoxide. If your furnace’s pilot light is flickering or burning yellow, you must turn off your furnace and contact an HVAC contractor. Otherwise, you risk exposing your family to carbon monoxide poisoning. When it’s operating correctly, your furnace’s pilot light should always burn blue.

High-Pitched Squeal

It’s normal for your gas furnace to make sounds as it turns on and off and during operation. But these sounds should be relatively quiet. If you hear high-pitched squealing, it’s because the furnace has a slipped or frayed blower belt. Don’t worry, though. A professional HVAC service technician can replace this furnace component easily.

Some gas furnace issues are repairable, while others signal the need for a complete replacement. To schedule a gas furnace repair or installation, contact Magnolia Heating and Cooling at 951-595-4737 today.
