Some simple maintenance tasks, like replacing air filters or clearing debris from around the unit, can be handled on your own.

In an ideal world, homeowners would not have to worry about their heating systems making any strange sounds. However, this is not always the case and it is important to know what types of sounds are normal versus those that should be a call for service. Whether you are a new or experienced homeowner, knowing what your system is supposed to sound like can help you determine when it is time to seek professional assistance with your heater.

Loud banging noises are usually the biggest indicators that something is not right with your system. This sound often occurs when the ignition system or pilot light experiences a hiccup when starting up. The system is supposed to spark the gas immediately when it gets the green light from the thermostat, but this doesn’t always happen and the gas hangs out in the combustion chamber until it is ignited again. This can result in a loud banging sound that is heard throughout the home.

Other common sounds that may be heard from your furnace include humming and clicking. A soft hum is a normal sound that can be heard from most heating systems when they are running and this should not be cause for alarm. However, if the sound becomes louder during operation or it appears to be occurring at times when it is not normally present then this could be an indication of a motor issue and should be looked at by a technician.

Rattling sounds may also be a sign that the system is in need of repair. This can be caused by loose screws and panels that have begun to rattle as the system runs. This is typically a minor problem that can be resolved with a quick heater repair visit and the replacement of some small parts.

Screeching sounds can also occur from the heater and this is usually a sign of a problem with the motor bearings. This is a common symptom of wear and tear on the components within a forced air system and should be looked at by a qualified technician as soon as possible to avoid the need for more costly repairs later.

Yellow Flames

If your furnace’s flames are yellow or orange, that’s a clear sign you need to schedule immediate heater repair services. These flames indicate incomplete combustion that can leak carbon monoxide into your home. The presence of carbon monoxide poses serious health risks, especially to children and seniors.

The most common reason for a yellow burner flame is dirty burners that need to be cleaned. Over time, dust and other contaminants can build up on the burners, interfering with the proper balance of fuel and oxygen necessary for a blue flame. A professional technician can clean the burners to remove these contaminants and restore the blue flames.

Another potential cause of a yellow burner flame is a malfunctioning gas valve. This part of the heating system controls the flow of gas to the burner assembly, and it’s essential for ensuring the correct mixture of fuel and air for proper combustion. A technician can assess the gas valve for problems and repair or replace it as needed.

A yellow or orange flame can also be a sign that the heating system isn’t supplying enough oxygen to the combustion process. This condition may require the installation of a new air filter to ensure proper airflow.

Finally, a yellow flame can be caused by an electrical problem with the heating system’s ignition switch or thermostat. These parts of the system are responsible for turning on and off the burners, so if they’re malfunctioning, it can cause an improper mixture of fuel and air and produce yellow or orange flames.

A steady, blue flame is the hallmark of a healthy furnace. A professional inspection and maintenance can keep your system running as intended, reducing energy bills, lowering your risk of a fire, and minimizing carbon monoxide leaks in your home.

Unusual Temperatures

If your heater starts heating up erratically, it could indicate problems with the system’s thermostat or even a problem with the system itself. A thermostat that malfunctions can lead to inconsistent heat distribution in your home, and a damaged heater might also prevent the ductwork from properly distributing air.

When temperatures plunge to extremely low levels, your heater may have to work overtime to maintain a comfortable indoor temperature. This extra strain can place unnecessary wear and tear on the various components in your unit. Over time, this can cause them to fail, which is why it’s so important to take notice of any unusual heating issues as soon as they crop up.

A well-functioning heater should operate quietly, producing only a soft hum or the sound of blowing air. Unusual noises like rattling, banging and creaking are sure signs that something is amiss with your heater. These sounds are often caused by loose or damaged parts inside the unit, and ignoring them can exacerbate the issue and lead to more costly repairs.

Uneven heat distribution in your home is another indication that you need a heater repair expert to visit your house. This could be caused by a variety of things, from faulty thermostats to blocked or dirty ductwork. It’s essential to get this issue addressed as quickly as possible to avoid a cold and uncomfortable winter.

Your heating system is supposed to provide warm air throughout your entire home. If you notice that some areas feel warmer than others, it’s a sign that the system is not working as it should be. Uneven heat distribution can occur for a number of reasons, including insufficient heating at the thermostat level, poor airflow through the ductwork, or dirt and debris accumulation in the ducts and air filters.

When a heater isn’t working, it can create dangerous fumes that might leak into your living space. These fumes can make you sick and lead to a range of health complications. It’s important to have any leaking gases, such as carbon monoxide, checked and repaired right away. In most cases, these gases can be detected with a simple carbon monoxide detector, which you should have in your home. If the detector detects high levels of carbon monoxide, you should immediately leave the building and call 911.

Low Fuel Levels

If your heater turns off, it is always a good idea to check to make sure that the problem isn’t related to a low fuel oil level. Most tanks have a gauge that lets you know how much oil is left, and if it’s below half a tank, it’s a good idea to call for a home heating oil delivery service.

If the tank is full, and your heater just seems to be acting up, try opening the panel on the front of the burner and pressing the reset button (if there is one). It may dump a little extra oil into the system, and get it working again. Just be careful not to push the reset button more than once, as it can cause your system to flood, which will require a costly repair.
