Signs That Your Gas Furnace Needs Repair

With winter right around the corner, it’s more important than ever to ensure your furnace is working correctly. Since this appliance is not used for a majority of the year, it can fall into disrepair without you even noticing. Before the cold weather arrives, be on the lookout for these five warning signs that your furnace needs to be inspected and repaired.


Trouble Starting Up

Old furnaces have more difficulty turning on than newer units. If you find yourself needing to start and restart the unit multiple times throughout the day, contact an HVAC professional. This problem is typically caused by a damaged thermostat or damaged wiring. No matter the cause, a professional can assess the situation and repair the damage.


Not Enough Heat

This is an obvious sign that your furnace is not working as well as it should. Schedule heating services in Atlanta as soon as possible if your furnace is not producing heat or is only producing a low level of heat unrelated to the setting of the thermostat. Often, this issue occurs because of a defective thermostat or a leaking air duct.


Unusual Smells

After a long summer of rest, many homeowners notice that their furnace smells like fuel the first time they turn it on. Typically, these smells dissipate as the furnace continues to run. These odors can also signify a deeper problem. Watch out for scents that don’t go away over time, strong fuel odors, and smells that appear suddenly. These can be signs of anything from a dusty unit to a gas leak. Be sure to contact a professional to determine the root of the scent.


Consistent Noise

Though no furnace is totally silent, constant noise can suggest that your unit needs repairs. Take note of the sounds you hear so you can describe them to the repair professional when they arrive to inspect your unit. Banging and groaning noises can be caused by loose or broken internal pieces. Whistling and squealing sounds can indicate a problem with the fan or belt.


Pilot Light

Look at the color of the pilot light. If the unit is fully functional, the pilot light should be blue. If the light is yellow, it can mean the furnace has a ventilation problem. The color of the light changes when carbon monoxide and other gases don’t dissipate as they should, which can lead to health problems for your family or even cause the unit to become more combustible. If you notice any of these five common signs, be sure to contact an HVAC contractor immediately to get the problem repaired.
