For a furnace to fully operate and function with minimal failure, the owner must carry out preventive care for each part of the system at the appropriate time. The most important elements include the burners, pipes, blowers, lubrication system, electric arc, and filter area.

Burners, Pipes, and Filter areas

The furnace burners require an inspection every three months to ensure that the ignition rod is working correctly and that no leaks could affect the ignited flame. Additionally, this ensures that temperatures are regulated perfectly.

Furnace preventive care recommends cleaning the piping system to prevent blockages from dirt, soot, and debris. Also, it’s necessary to clean out the pipes in the areas where high temperatures occur.

The filter areas require change since filters wear out quickly, and over time, they no longer perform the same function; thus, it is necessary for change. The air filters accumulate smoke and debris that can block the fan motors, preventing the release of hot air.

While cleaning out the filters, please remove them and immerse and soak them in boiling water that adds baking soda and dish soap. Then rub the areas with stuck dirt, dry them, and put them back into the heating system.

Regular Cleaning

Furnace preventive care professionals recommend performing a thorough deep cleaning at least once a year to clean out the accumulated dirt, debris, soot, and other unwanted materials from the furnace. However, regular cleaning for about three to four months a year is essential to reduce excessive damage.

During cleaning, you can use a humid dump cloth to wipe off the dust. Ideally, use a vinegar-soaked material to wipe off the dust. It is necessary to clean out the packaging area of the furnace. Additionally, clean through the glassy areas and remove the accumulated excess dirt with a damp cloth around the glass.

A little degreaser can remove the soil thoroughly if the glass contains excess dirt or soot. However, avoid using abrasive fibers and cloth that can get stuck in the furnace system and cause clogging or become a barrier to the functioning of the appliance.

Lubricate the Fan Motor

The fan motor is a critical element of the furnace as it controls and regulates the release of hot air during the performance. Therefore, cleaning the engines with oil at least twice a year is vital to keep the internal temperatures constant.

However, furnace preventive care measures suggest lubricating the motor when the air filters are clean. Moreover, different furnaces have specific manual guidelines; thus, check out the manual to know how to proceed while lubricating.

Check For Defects

When the furnace is not heating correctly or may experience faultiness, it is necessary to solve the issues quickly to prevent the problem from accelerating further to cause severe damage.

The temperature degrees of the furnace should be five degrees above the house temperature.  Another way is to read the appliance manual to know how to recalibrate or find information concerning your specific model on how to fix the temperature issues.

Inspect the Gas Line 

Another furnace preventive care is to inspect the gas line from the central interior up to the furnace burners. You can achieve this by switching off the furnace or the gas chamber, standing close to the stove, and following the gas line. Perform inspection to ensure that the gas line remains open. 

Additionally, if the furnace consists of a pilot light, check if it is on and if not, follow the manual to re-light it. Suppose the pilot light fails to stay on after a few times; call a repair technician to handle the situation.  Moreover, inspecting the gas line allows early detection of gas leaks that, if left unattended, can cause great harm when the furnace heating system is on. 

The furnace can blow out, hurting anyone in the house, and in severe cases, the house may catch fire, which damages more properties. Thus, regular gas line inspection is essential as a preventive care measure.

Clean the Heat Pumps or Intake and Exhaust Vents

Furnaces installed to vent outside the house attract most leaves, dirt, and debris, which can block the intake and exhaust process. So to ensure quality furnace preventive care, ensure that a mesh hardware cloth of half an inch covers the pipes with a screen mesh. 

If the pipes are clogged, the system may run slowly and cause many fluctuations; thus, clean the lines to avoid blockage. In some scenarios, ice may block the pipes: clear it out and call a technician to help diagnose why it’s forming and its source.

Ensure the grass and leave from the outdoor compressor unit for the heat pumps and exhaust vents is well cleared. Additionally, use a hose pipe and gently remove and rinse the dirt and debris out of the fan housing.

Also, check out the vents by walking through the house to ensure that nothing is blocking them and no material is preventing the heat flow and release.

Know the Age of Your Furnace

It’s essential to know the furnace’s age since they all have a given period of operation. Also, this helps you to avoid high maintenance costs and utility bills to lower energy efficiency. On the other hand, it helps you know which measures and preventive care you will adopt to extend the functionality and operation of the furnace.

Also, since most of these appliances have a warranty period, it is necessary to know when the warranty expires to ensure that you receive the needed heating productivity. Additionally, you will know whether to continue with repairs or purchase a new appliance.

Flame Sensor Cleaning

The flame sensor is a vital safety element in the furnace since it safeguards the furnace from unsafe fuel burning. A dirty flame sensor can result in improper functioning of the stove hence the need for cleaning as a preventive measure.

Poor cleaning of the flame sensor can result in the buildup of oxidation and carbon that can prevent the sensor’s ability to perform correctly, resulting in the furnace malfunctioning. While this process is challenging, a furnace repair technician’s presence helps clean out the dirt and complete a diagnostic procedure.
