With cold weather heading your way, you will be using your furnace often soon. The last thing you want is for the system to stop working entirely on a frigid day. That is why it is important to recognize early warning signs that your furnace is not working the way it should and is in need of an HVAC repair.

If your furnace has been making whistling noises, the belt may be loose. Have an HVAC professional inspect your furnace soon to determine what the issue is.

Either way, it is important to call an HVAC professional immediately to repair the problem. You don't want to be sitting in a freezing cold house all winter.
Higher Electricity Bills
If your electricity bills have been much higher than normal lately, it can be alarming. If you haven't used more electricity than you normally do, the problem could be your furnace. If one of the components isn't working properly, it could force your furnace to to work harder, driving up your energy bills.
Reduced Air Quality
A furnace can affect the air quality in your home more than you think. If something is wrong with your furnace, it may move dust, dirt and other particles throughout the air. This may cause coughing, sneezing and other unpleasant symptoms among those who have allergies. Have an HVAC professional thoroughly clean your furnace to rectify this issue.
It is not normal for furnaces to produce bad odors as they operate. If you have noticed a strong odor coming out of your furnace recently, there is likely an issue, like a gas leak or too much dust inside the appliance. It is crucial to have an HVAC professional look at your furnace and determine why it is producing foul smells.
If your furnace has been displaying any of these signs, you should call an HVAC professional as soon as possible. If you wait too long to address the issue, it will only get worse and may result in total system breakdown.
