Furnace Heating Repair: Common Problems and Solutions
Furnace Heating Repair: Common Problems and Solutions
While modern furnaces are built to last and keep your home warm during the cold months, they require regular maintenance and occasional repairs to function effectively. Without proper care, furnaces can develop issues that affect heating efficiency or cause complete breakdowns. Here, we cover some common furnace problems, troubleshooting tips, and guidance on when to call in a professional for furnace heating repair.
Clogged or Dirty Air Filter
Over time, filters accumulate dust and dirt, which restricts airflow, reduces heating efficiency, worsens indoor air quality, and can even cause the furnace to shut off. To keep your furnace running smoothly, check the air filter every 30 days. If you hold the filter up to a light and can’t see through it, it’s time to clean or replace it. Make sure to follow the manufacturer’s instructions when installing a new filter.
Thermostat Issues
After checking the air filter, the thermostat should be your next point of troubleshooting. Sometimes, the thermostat is not set correctly, or it may simply need fresh batteries.
To test it, set the thermostat to “heat” and increase the temperature by five degrees above the room temperature. If this doesn’t turn on the furnace, check for other issues. Make sure the thermostat isn’t affected by external heat sources like sunlight or space heaters, as this can cause inaccurate readings.
Furnace Flame Color
The color of your furnace flame is an indicator of proper operation. A healthy gas furnace flame should be blue with a small yellow tip. If you notice other colors—such as yellow, red, or green—there may be an issue with fuel combustion or even a gas leak.
Never attempt to adjust the flame on your own. If you see anything unusual, call an HVAC professional immediately for an inspection.
Pilot Light and Gas Valve Issues
In gas furnaces with a pilot light, an extinguished pilot can prevent the furnace from producing heat. You can relight it yourself if you follow the instructions in your furnace manual carefully. Before you do, turn off the gas and wait for about 10-15 minutes. If you continue to smell gas, evacuate the building immediately and contact your gas company, as this could indicate a dangerous leak.
Proper Panel Placement
Modern furnaces have safety features that prevent them from operating if the front panel isn’t secured correctly. If you’ve recently had maintenance done or changed the filter, double-check that the access panel is firmly in place.
Unblocked Vents and Registers
In some situations, your furnace may be running, but your rooms may not feel adequately heated. Check that all vents and registers are fully open and free from obstructions. Items like rugs, furniture, or curtains can block airflow and reduce heating efficiency.
