As the snow starts to dust the Wasatch Range and the chill creeps into the air, Utah residents rely heavily on their furnaces to keep their homes cozy.
But what happens when your trusty furnace starts acting up? A malfunctioning furnace can leave you feeling cold and uncomfortable, not to mention potentially lead to higher energy bills.
Learning to troubleshoot basic furnace problems can save you a service call and ensure your home stays warm throughout the winter. This article will equip you with the knowledge to identify common furnace issues and take appropriate steps to get your heating system back on track. However, it’s important to remember that some repairs are best left to the professionals.
If you suspect a complex issue or lack the confidence to tackle the problem yourself, Nebo Comfort is here to help! Our team of qualified technicians in Utah can diagnose and repair your furnace quickly and efficiently, ensuring your home stays warm and safe all winter long.
Now, let’s delve into some common furnace problems and how to troubleshoot them:
The Furnace Won’t Turn On
The most obvious sign of trouble is a furnace that refuses to turn on. Don’t panic! Here are some steps you can take:
- Check the Thermostat: Ensure the thermostat is switched to “heat” and set to a temperature higher than the current room temperature. Also, make sure the batteries haven’t died (if it’s a battery-powered model).
- Inspect the Power Supply: Verify that the furnace is plugged in and the circuit breaker hasn’t tripped. If you locate a tripped breaker, reset it cautiously. However, if it trips again immediately, seek professional help.
- Check the Fuel Supply: For gas furnaces, ensure the gas supply valve is open. If you have a fuel oil furnace, check the fuel tank gauge and refill it if necessary.
- Change the Air Filter: A dirty air filter can restrict airflow and prevent the furnace from igniting. Replace the air filter with a clean one according to the manufacturer’s recommendations.
The Furnace Turns On and Off Frequently (Short Cycling)
Short cycling describes a situation where your furnace kicks on, runs for a brief period, then shuts off prematurely without completing a full heating cycle. This repeated on-and-off pattern can be inefficient and put strain on your furnace.
Here are some potential causes of short cycling:
- Dirty Air Filter: As mentioned earlier, a clogged air filter can restrict airflow, causing the furnace to overheat and shut off.
- Dirty Burner: Over time, burners can become clogged with soot and debris, hindering their ability to generate heat efficiently. This can lead to short cycling as the furnace struggles to reach the desired temperature.
- Faulty Limit Switch: The limit switch helps regulate furnace temperature. A malfunctioning limit switch might cause the furnace to shut off prematurely.
Uneven Heating Throughout Your Home
One of the primary functions of a furnace is to provide consistent heat distribution throughout your home. If some rooms feel significantly colder than others, it might indicate several issues:
- Blocked Ducts: Furniture or debris blocking air ducts in specific areas can prevent warm air from reaching those rooms. Check your ductwork for any obstructions.
- Closed Vents: Ensure all vents in your home are open and unobstructed.
- Zoned Heating System Issues: If you have a zoned heating system, it’s possible that the zone control settings may not be calibrated correctly.
The Furnace is Making Strange Noises
A healthy furnace typically produces a low hum when operating. However, unusual noises can be a sign of potential problems. Here’s a breakdown of some common noises and what they might indicate:
- Banging or popping: This could be caused by expanding and contracting air ducts or a dirty burner.
- Rattling: Loose components or debris inside the furnace or ductwork might cause rattling noises.
- Squeaking: High-pitched squeaks might indicate problems with the blower motor or belt.
- Grinding: Grinding noises could signal worn-out bearings in the blower motor.
Addressing Unusual Odors
While a slight burning smell might be noticeable during the first few hours of operation after a new furnace installation, any persistent unusual odors should raise red flags:
- Burning smell: This could indicate overheating components or a dirty furnace. Turn off the furnace and address the issue promptly to prevent potential fire hazards.
- Gas odor: The smell of natural gas is a serious concern and should be addressed immediately. If you suspect a gas leak, turn off your furnace, evacuate your home, and call a qualified technician or your gas company.
When to Call a Professional
While some furnace issues can be addressed with basic troubleshooting, it’s important to recognize when to seek professional help. Here are some instances where it’s best to call a technician:
- Complex Issues: If you’ve tried troubleshooting and the problem persists, it’s time to consult a professional.
- Safety Concerns: Gas leaks, electrical problems, or signs of carbon monoxide poisoning are serious safety hazards and require immediate attention from a qualified technician.
- Lack of Expertise: If you’re unsure about troubleshooting steps or feel uncomfortable working with electrical or mechanical components, it’s safer to leave the repairs to a professional.

- Schedule Annual Inspections: Have a professional technician inspect your furnace annually to identify potential issues and perform necessary maintenance.
- Clean the Exterior: Remove dust and debris from the exterior of the furnace to improve airflow and prevent overheating.
- Keep the Area Around the Furnace Clear: Avoid placing objects near the furnace that could block airflow or create fire hazards.
