5 Common Gas Furnace Problems (and Solutions)

When the temperatures start to drop, it is essential to ensure your gas furnace is in tip-top condition, ready to keep your home cozy and warm. However, even the most reliable gas furnaces can run into problems. Recognizing these issues early can save you from cold nights and unexpected repair bills. Here are 5 common gas furnace problems and solutions. If you find these issues too challenging to tackle on your own, remember, that the heating professionals at Fante’s are just a call away for furnace services you can depend on.

Typical Furnace Issues and Solutions

1. Furnace Not Producing Enough Heat

Problem: One of the most common complaints is that the furnace isn’t heating enough. This can be due to a dirty filter restricting airflow or incorrect thermostat settings.

Solution: First, check and replace your furnace filter if it’s dirty. Next, ensure your thermostat is set to “heat” and the temperature is set higher than the current room temperature. If the problem persists, it might be due to a more complex issue, like a malfunctioning blower motor or a problem with the furnace’s burner. In such cases, it’s best to contact Fante’s heating professionals to diagnose and fix the problem.

2. Furnace Not Turning On

Problem: Several issues can prevent a furnace from turning on, including problems with the thermostat, power supply, or the furnace’s pilot light or ignition system.

Solution: First, ensure that the thermostat is set correctly and that there’s power to the furnace. If your furnace has a pilot light, check if it’s lit. Newer furnaces with electronic ignition systems might require a professional’s touch if they fail to ignite. If you’re unsure, it’s safer and more efficient to call in the experts at Fante’s.

3. Frequent Cycling

Problem: If your furnace turns on and off more frequently than normal, it might indicate a clogged filter, improper airflow, or a faulty thermostat.

Solution: Begin by checking and replacing the air filter if necessary. If that doesn’t solve the problem, inspect the thermostat for issues and ensure that all vents in the house are open and unblocked. If the problem continues, this could indicate a more serious issue that requires professional attention.

4. The Furnace Blows Cold Air

Problem: A furnace blowing cold air can be due to a variety of reasons, including a problem with the thermostat setting, the pilot light, or the furnace’s flame sensor.

Solution: Ensure your thermostat is set to “auto” and not “on,” which keeps the fan running even when the furnace isn’t heating air. Check the pilot light in older furnaces or the flame sensor in newer models. Sometimes, cleaning the flame sensor can resolve the issue, but if you’re not comfortable doing this yourself, Fante’s professionals are here to help.

5. Unusual Noises

Problem: Strange noises coming from your furnace, like banging, whining, or grinding, can indicate mechanical problems, airflow reductions, or a clogged burner.

Solution: Some noises can be fixed by replacing the air filter or adjusting the belt tension. However, if the problem is related to the internal components, like the heat exchanger or blower motor, it’s crucial to get professional help. Ignoring these sounds can lead to more significant issues down the line.
