As the weather becomes colder, you depend on your furnace to keep your home warm and comfortable. While furnaces are typically very reliable, they can occasionally break down and eventually must be repaired. Common problems include cracked heat exchangers, clogged burner assemblies, and faulty igniters. There are several signs your furnace needs to be fixed sooner than later.
The Furnace is Making Strange Noises
If your furnace produces unusual noises, it’s essential to take action immediately. These noises can indicate a serious issue that, if left unaddressed, could lead to a complete breakdown of your furnace. Some of the most common strange noises furnaces make are hissing, banging, popping, and humming. Sometimes, these noises can be caused by simple issues like loose parts or restricted airflow. However, they can also indicate more severe problems like cracks in the heat exchanger or pilot light issues. Qualified HVAC technicians can diagnose the problem and perform a furnace repair if needed.
The Pilot Light is Yellow Instead of Blue
One of the essential components of your furnace is the pilot light. This small flame is responsible for igniting the burners, which heat your home. A properly functioning pilot light will be a steady blue flame. If your pilot light is yellow, it signifies something is wrong. The most common cause of a yellow pilot light is a dirty burner. When the burner is dirty, it doesn’t get hot enough to vaporize the gas entirely. This causes the gas to escape unburned, leading to a yellow flame. In some cases, a yellow pilot light may also be caused by a draft. Whatever the cause of your yellow pilot light, it’s essential to have it checked out as soon as possible. Ignoring a problem with your furnace can lead to expensive repairs down the road.
The Furnace Produces Insufficient Heat
Furnaces can sometimes break down, leaving homeowners struggling to stay warm. One common problem is that the furnace doesn’t produce enough heat. This can be caused by several factors, including a dirty filter, incorrect thermostat settings, or a faulty heating element. Fortunately, a qualified technician can quickly and efficiently resolve most furnace problems. By getting to the source of the matter, they can ensure that your furnace runs efficiently and keeps your home nice and warm.
The Furnace is Emitting Strange Smells
If you notice your furnace emitting strange smells, it’s crucial to take action immediately. While some smells may indicate that your furnace needs a good cleaning, others could indicate a more serious problem. A burning smell could mean that there is dust or debris caught in the blower fan. If left unchecked, this could finally cause the fan to overheat and break down. Alternatively, if you notice a musty smell, it could be a sign of mold or mildew growth. If mold or mildew is present, it’s essential to have the problem addressed promptly, as it could cause respiratory issues for you and your family.
Uneven Heating in the Rooms
One of the most prevalent furnace issues is uneven heating. This means that some rooms in your home are warmer or cooler than others. Several factors can cause uneven heating, but one of the most common is a faulty blower motor. The blower motor helps circulate air throughout your home, and if it isn’t working correctly, it can make your furnace overheat or underheat certain areas. Another possible cause of uneven heating is an issue with your ductwork. If your ducts are leaky or poorly insulated, they can cause your furnace to work harder to heat your home, leading to uneven temperatures. If you note that some rooms in your home are warmer or cooler than others, it’s essential to have a professional inspect your furnace to determine the cause of the problem.
Your Energy Bills Have Skyrocketed
An increase in your energy bill is often one of the first signs that something is wrong with your furnace. As the furnace overworks to heat your home, it uses more energy and drives up your utility bills. This problem has several potential causes, from a dirty filter to a faulty thermostat. If you notice an unusual spike in your energy bill, it’s essential to take action immediately. A qualified HVAC technician can inspect your furnace and diagnose the problem. In many cases, a simple repair can resolve the issue and restore your furnace to normal operation.
The Furnace is Over 15 Years Old
The typical lifespan of a furnace is 15 to 20 years. If your furnace has more than 15 years, it is likely nearing the end of its useful life. At this time, you may be wondering whether you should repair or replace your furnace. There are several factors to consider when making this decision, including the age and condition of your furnace, the cost of repairs, and the efficiency of newer models. If your furnace is outdated or inefficient, replacing it with a new model can help you save money on energy bills.
The Furnace Runs Continuously
A furnace that runs non-stop is not only inefficient in energy use but could also indicate a more significant problem. Furnaces are designed to cycle on and off to maintain a consistent temperature. If the furnace runs continuously, it could be overcompensating for a drop in air pressure. This drop in air pressure can be caused by several factors, including leaks in the ductwork or a clogged air filter. In some instances, the issue can be with the thermostat itself. Regardless of the cause, it’s essential to have the issue diagnosed and repaired as soon as possible.
The Furnace Kicks On and Off Frequently
If your furnace is short-cycling, it means that the furnace is turning on and off more frequently than usual. Various factors can lead to this, but the most common cause is a dirty or clogged air filter. When the air filter is blocked, it causes the furnace to overheat. The furnace will then turn off to prevent damage, but it will turn back on again once it has cooled down. This cycle will continue, provided the air filter remains dirty. In some cases, short cycling can also be caused by a faulty thermostat or an oversized furnace. If you suspect that your furnace is short-cycling, it’s essential to have it inspected by a qualified technician. If left unchecked, short cycling can lead to significant wear and tear on your furnace, resulting in costly repairs.
A faulty furnace can lead to several issues, including carbon monoxide poisoning and fires. As a result, it is essential to have your furnace regularly inspected by a qualified technician. Additionally, you should be well informed of the signs that your furnace needs repair, such as strange noises or decreased efficiency. Being proactive about maintaining your furnace can help keep your family safe and warm all winter.
