Some homeowners wait until their furnace stops working to start looking for money to replace it. They usually ignore the groans and warning signs that indicate it is about to fail. They don’t realize that a furnace ages gracefully until it kicks the bucket on one of the coldest winter nights.
So, homeowners who don’t want their heating systems to break down when they need them the most should watch out for early warning signs and replace the furnace when the existing one is on its last leg. This article will highlight a few indications the furnace is about to fail.

Sudden Increase in Energy Bills
The furnace accounts for a significant percentage of the monthly energy bill. So, a sudden spike in the energy bill might indicate that the heating system is faulty. Generally, keeping your furnace well maintained ensures it runs efficiently and consumes less energy, especially if it is relatively new.
The furnace needs replacement if a homeowner receives high energy bills without changing the heating patterns. Fortunately, modern furnaces have an energy efficiency rating, which helps homeowners choose the most efficient option that meets their needs.
Old Age
Old furnaces are less efficient than new ones and are likely to fail unexpectedly. If a furnace has been used for a decade or repaired severally, replacing it is the best option. Repairing an old furnace might be too expensive, and ignoring the warning signs might expose the house occupants to hazards.
Old furnaces take longer to warm the house or heat all the rooms. Homeowners with old furnaces can replace them with modern ones to avoid inconveniences and enjoy advanced features.
Dry and Dusty House
A furnace that is near the end of its useful life will struggle to keep indoor air clean and humid. The first signs of breathing dry skin include family members having dry skin and sinuses. However, the same problem could occur if the humidifier is set too low or the warm air is escaping outside.
Excessive dust on furniture and electronics also indicates that the furnace is faulty. The air purifier may not work as usual, or the entire system could be on its last leg. Buying a new air purifier and installing a humidifier could solve the problem temporarily, but replacing the furnace is inevitable in the long run.
Strange Noises
Worn-out parts or loose nuts could cause strange noises from the furnace. These noises could also indicate the furnace is about to break down. Bagging sounds are common in old heating systems and could indicate faulty ignition, heat exchangers, or other components.
Ignoring these signs could cause more damage and increase safety concerns. Issues with the belt, motor, blower, and fan could cause high-pitched noise that makes everybody uncomfortable. If the cost of replacing faulty parts is too high, replacing the entire system might be a much better option.
Weird Smell
Weird smells from the heating system might indicate it is overheating or has frayed wires, a mold infestation, or leaking gas. Since leaking gas could cause fire or affect human health, homeowners should switch off the heating system first.
If the system has been developing this problem often, replacing it is the best solution. Delaying replacement could expose the occupants to fire or health complications.
A good furnace operates quietly and consumes less energy. It supplies warm, quality air throughout the house quickly and efficiently. So, if a homeowner notices these warning signs, they should start planning for replacement.
