It's difficult to talk about modern heating systems without talking about the heater. But just as it's a source of comfort during the cold winter, it can also be the bane of your problems if it's not well maintained. Luckily for heater owners, there are plenty of ways to spot any defects in your heater before the dreaded cold months.
Here are some of the warning signs that there is a problem with your oven:
- Higher energy bills than usual
A sharp increase in heating costs may be an indication that your furnace needs servicing. The sudden and unexplained increase may mean that the furnace is working harder than prescribed to maintain optimal temperature. Some of the most common causes of these inefficiencies range from a clogged filter to a faulty thermostat to the age of the furnace.
- Uneven heating
Sometimes you may notice different temperature readings in the rooms of your home or that the temperature fluctuates frequently. This is a clear sign of erratic heating, which in turn is an even clearer sign that your furnace may have a problem. In fact, this is one of the main reasons to call a professional to repair your furnace. It is advisable to hire a professional HVAC (heating, ventilation, and air conditioning) technician to diagnose and fix the problems so that your furnace can function optimally again.
The most common furnace defects that cause uneven heating performance include a dirty air filter, a problematic thermostat, and faulty blower motors. Dirty burners, a faulty ignition, or a furnace that is too large for your home can also be the cause.
- Strange noises and smells from the oven
Popping, screeching, or rattling noises coming from your furnace may indicate loose components that need to be tightened. It could also indicate an electrical problem. These are serious causes for concern.
In some cases, the furnace may not be making any strange noises, but it may be making strange smells. These can range from a musty smell to a burning smell. The first smell may be caused by mold growing in the furnace, while the second smell may indicate a faulty motor.
You should not ignore these strange noises and smells in your maintenance routine, as they can easily lead to significant problems if left unattended.
- Yellow flames coming from your oven
A properly functioning furnace should always produce a blue flame. Yellow flames can be a clear indication of a carbon monoxide leak. Carbon monoxide is an odorless, colorless gas that can cause headaches, dizziness, and sometimes death.
If you notice a yellow pilot light (a small, continuous flame that ignites the main burner of a gas furnace or water heater), turn off the furnace immediately and contact a furnace service professional. It is also advisable to have a carbon monoxide detector in your home to alert you in case of a leak.
- Frequent repairs
The need for frequent repairs on your furnace can indicate a number of things, including the furnace's advanced age, poor installation, lack of regular maintenance, overuse, or even substandard parts. If you find that you're constantly having to replace and repair parts of your furnace, have it inspected by an HVAC professional to determine the root cause of these frequent repairs and whether you already need a new furnace.
- Poor airflow
Airflow is the movement of air through the furnace's heating system. Proper airflow means even heat distribution, while improper airflow indicates a defect in your furnace. The most common causes of airflow problems include a dirty air filter, which may be clogged with dirt or debris. This restricts airflow and results in uneven heating. Other possible causes of poor airflow could be:
- Blocked vents or registers: Vents or registers can become inadvertently blocked by furniture or other objects in the home. This can restrict airflow and reduce the efficiency of the furnace.
- Ducting problems: Leaks, holes, or broken ducts can cause air to escape before it reaches the rooms in your home. This can easily lead to uneven temperature distribution in the home.
- Blower Motor Problems: If the blower motor is not working properly or is not operating at full power, it can reduce airflow. This will inevitably cause the furnace to overheat.
- Incorrect fan speed setting: If the fan speed is too low, it can reduce airflow and result in poor heating performance.
In addition to uneven heating, such scenarios can result in reduced heating efficiency and poor indoor air quality. If your fan is having airflow issues, contact a professional to determine the cause and learn about available remedies.
Farewell shot:
If you notice the signs of furnace problems mentioned and discussed above, don't hesitate to contact a heating, ventilation, and air conditioning professional. It could be the difference between having the heat you need this winter or feeling helpless in the cold. Take immediate action to avoid further problems that will only lead to costly repairs.
