What Types of Furnaces Overheat?
Any furnace can overheat in Alabama. Sometimes, homeowners neglect annual furnace maintenance inspections, but other times, the gas line is to blame. To avoid an overheating furnace, homeowners must pay attention to the warning signs.
What Happens When The Furnace Overheats?
Furnace fires are not the only dangers of overheating. While it is a common issue if overheating is ignored, other damages can also wreak havoc. Furnace overheating can cause the unit to malfunction or completely shut down. Typically, this happens when cracks form in the heat exchanger. The heat exchanger is responsible for keeping toxic gases away from heated air. Even a small amount of damage can cause carbon monoxide to spread throughout the home.
Carbon monoxide poisoning affects the entire household and can cause memory problems, dizziness, and even death. Discolored wiring and corrosion inside the unit usually indicate prior overheating and should never be ignored. If a homeowner suspects overheating, they must call a professional before using the furnace.
3 Signs The Furnace Might Be Too Hot
Furnaces are usually located in the basement or garage. Most furnace fires are detected by smell unless homeowners are inside the same room.
Even if smoke is not visible, homeowners often report a burning smell from the vents. This does not necessarily mean the furnace is on fire, but it does mean it must be turned off immediately. For safety reasons, calling a professional is advised.
Overheating furnaces also make strange noises. A light humming noise in the background is usually normal, especially for older furnaces, but banging or clanking noises are not. Depending on which component is affected and how, these sounds can be high-pitched squealing, rattling, or popping.
Uneven heating cycles are another way to tell if the furnace is too hot. If the furnace repeatedly turns on and off, the safety function is consistently activated. If this occurs, it can also cause energy bills to fluctuate.
Prevent Overheating This Fall
Annual maintenance is necessary to ensure the entire heating system is working. Trained technicians will check for cracks in the heat exchanger and faulty ductwork. Although ductwork is accessible to homeowners, it can be extremely dangerous, especially if the insulation is made from fiberglass.
Homeowners can help reduce the chances of overheating by turning down the thermostat and opening the vents. Hot air trapped inside the ventilation system puts undue pressure on the furnace. Opening the vents will help with circulation, easing the work necessary to heat the home (and reducing energy bills).
Furnace filter replacement also prevents poor airflow. Air filters are easy to replace and can be purchased online or at a local hardware store. Most households will need air filter replacement once every three months unless they have pets. Homes with multiple pets will likely need to change their filters once every other month.
The condensate drain line is an important part of heating. Without proper cleaning, it is prone to becoming clogged. A mixture of vinegar and water can help flush excess debris from the line to prevent water backup from damaging the unit.
