Top Signs You Need Furnace Repair

You need to know that your furnace is operating safely and reliably. Many different issues can affect your heating system, so being familiar with the signs of trouble can help you head off problems. Here are some clear indicators that you may need Cartersville furnace repair.


Inconsistent Temperatures

Is your furnace struggling to maintain warm temperatures on cold winter nights? Do you find that temperatures vary between rooms or at different times of day? These signs point to furnace performance issues that require repairs before they lead to a complete shutdown.


Frequent Cycling

Your furnace maintains consistent temperatures by cycling on and off as needed. You should expect it to cycle a few times per hour, depending on how cold it is outside and your thermostat settings. More rapid cycling leads to increased wear and potential damage.


Rising Energy Bills

Some furnace problems aren’t noticeable until you open your monthly energy bill. Deterioration and damage can cause your furnace to run inefficiently. It may be able to keep your home warm for a while, but it uses more energy to do so.


Strange Noises

Modern furnaces are fairly quiet, but you are likely familiar with the sound your heating system makes. Any new noises can point to potential damage. Rattling, banging, grinding, and squealing can indicate mechanical problems that will only get worse.


Foul Odors

You shouldn’t notice any odors coming from a properly functioning furnace. Burning smells can indicate overheating or even a cracked heat exchanger. The distinct rotten-egg smell of a gas leak means that you should quickly exit the area and call emergency services.


Pilot Light Problems

The pilot light can be an early indicator of furnace problems. It should be a steady blue. Any yellow in the flame or flickering points to incomplete combustion, which can produce carbon monoxide.
