At Dixie Electric, Plumbing & Air, we’ve been helping homeowners with their heating needs since 1908. Over the years, we’ve seen just about every furnace issue you can imagine. If your furnace isn’t working right, don’t worry—you’re not alone! Let’s explore the seven most common furnace problems and what might be causing them.
1. No Heat Coming from the Furnace
This is one of the most common furnace problems homeowners experience. If your furnace runs, but there’s no warm air, it could be a problem with the thermostat, a clogged filter, or even a malfunctioning pilot light. Start by checking the thermostat settings and replacing the filter. If those don’t solve the issue, it’s time to call the professionals at Dixie.
2. The Furnace Keeps Turning On and Off
When a furnace turns on and off too frequently, it’s called short cycling. This problem is often caused by a dirty air filter, a blocked vent, or a thermostat that isn’t working properly. Short cycling not only leaves your home feeling uncomfortable but also wastes energy and puts unnecessary wear on your system.
To fix this, clean or replace the air filter and check that the vents are open and unobstructed. If the problem persists, a Dixie technician can take a closer look.
3. The Furnace Isn’t Blowing Air
If your furnace runs but no air is coming through the vents, there may be an issue with the blower motor, fan, or belt. Another possibility is a clogged air filter that’s preventing airflow.
Changing the filter is a simple DIY fix, but blower motor or belt issues require professional attention. Dixie Electric, Plumbing & Air is here to help with those more complicated repairs.
4. Unusual Noises from the Furnace
All furnaces make some noise, but loud or strange sounds like banging, squealing, or rattling are usually a sign of trouble. These noises can indicate loose parts, motor problems, or even something as simple as a slipped belt.
Ignoring unusual noises can lead to bigger problems, so don’t wait to address them. A technician can quickly diagnose and fix the issue to keep your furnace running smoothly.
5. A Pilot Light That Won’t Stay Lit
If your furnace has a pilot light and it keeps going out, it could be due to a dirty or faulty thermocouple, a gas supply issue, or a draft near the furnace.
Relighting the pilot light might work temporarily, but if the problem keeps happening, it’s best to have a professional check the thermocouple and gas lines to ensure your system is safe and functional.
6. The Furnace Isn’t Producing Enough Heat
A furnace that runs but doesn’t heat your home enough might have a dirty filter, a thermostat that needs adjustment, or a problem with the burners.
Start by replacing the air filter and making sure the thermostat is set correctly. If that doesn’t solve the issue, the burners may need cleaning or repair. Dixie Electric, Plumbing & Air can take care of that for you.
7. The Furnace Won’t Turn On
If your furnace won’t start at all, the problem could be as simple as a blown fuse, a tripped circuit breaker, or a dead thermostat battery. In other cases, it might be a bigger issue like a malfunctioning ignition system or motor.
First, check the fuse box or circuit breaker panel and replace batteries in the thermostat if needed. If your furnace still doesn’t turn on, it’s time to call in a professional to diagnose the problem.
How to Prevent Common Furnace Problems
While it’s impossible to prevent every issue, regular maintenance can go a long way in keeping your furnace running smoothly. Here are a few tips:
- Change the Air Filter Regularly: A clean filter improves airflow and prevents many furnace problems.
- Schedule Yearly Tune-Ups: Professional maintenance helps catch small issues before they become big problems.
- Keep the Area Around the Furnace Clear: Make sure nothing is blocking airflow or causing safety hazards.
- Test Your Thermostat: Check that it’s working properly and set to the right temperature.
