Here are 6 signs your furnace needs repairs this winter

#1. Your utility bills are getting more expensive

If it feels like your energy bills are significantly more expensive than last winter, this may be a sign of impending trouble. An inefficient heater may be caused by a variety of problems, from a simple dust buildup to a serious malfunction. Keep an eye on the cost of your electric bills as they come in each month, and call Southern if they’re starting to increase rapidly.

#2. There is not enough heat

The purpose of a furnace is to keep your home warm when you need it. If you are not adequate getting heat from the heater, this is a clear sign that something’s up. A lack of heating from your vents could signal an issue with the motor, blower fan, heat exchanger, or pilot light. All of these are reason enough to call in the professionals.

#3. Dust and dirt are coming out of the vents

Check the air ducts for any dust or dirt. This could be a symptom of a furnace failure. The technicians at Southern Air can inspect your HVAC system to determine the cause of the problem.

#4. Strange noises are coming from the furnace

When you turn the heater on, it should emit a basic blowing sound that eventually becomes white noise that you hardly notice. You shouldn’t hear anything out of the ordinary when you use the furnace. If you hear any rattling, banging, or whistling sounds, you should get it checked out. Also, listen for the sound of the system constantly starting and stopping. This could indicate that your furnace is consistently cycling on-and-off repeatedly, burning extra energy and adding wear-and-tear to the system.

#5. Abnormal smells

Furnaces may have a slight smell, especially when you use it for the first time in months. However, most odor goes away as it continues to run. If you smell something that appears suddenly or doesn’t go away, there may be a problem. Smells commonly occur because of gas leaks or excessive dust.

#6. Your carbon monoxide detector goes off

Your furnace and home are equipped with carbon monoxide detectors to alert you of toxic gas leaking into your home. If the unit starts beeping, make sure you turn your furnace off and leave your home. You’ll want to call in emergency authorities to confirm that your home is safe to return to, and then give your HVAC professionals a call to diagnose issues with your system.
