Air Filters

The filter keeps dust and other contaminants out of the system while allowing clean air to circulate. Due to its impact on the furnace’s overall performance, fuel efficiency, and lifespan, the filtration system needs to be given top priority during maintenance.

You must change the air filters at least once a month to guarantee that your appliance is operating properly. If you’re not sure what kind of filter your furnace has, get in touch with your neighborhood Lennox manufacturer. These experts will assist you in making the right filter selection for your appliance.

To prevent any equipment problems in the future, it is important to choose the appropriate component. Additionally, if you have pets and your furnace runs continually, the filter needs to be maintained frequently because it can be vulnerable to dust and fur accumulation.

Take Out the Dust and Grime

In order to keep the furnace clean and functioning correctly, regular checks for dust and grime are required. When a significant amount of dirt has gathered, vacuum the air registers to remove the dust.

Examine the Burner’s Flames

The efficiency of the heating system is indicated by the flame color. The presence of blue flames indicates a healthy furnace and pure, uncontaminated gas. When the combustion system is yellow or orange, it is inefficient. It might imply that there is debris or pollution.

Since carbon monoxide could be present in the circulating air, it is best to stop utilizing the system. The best course of action is to consult with and have the issue assessed by a specialist.

Clean the Burner

Heat is provided to the home using burners. It’s possible that accumulated dirt will keep the furnace from operating properly.

Step 1: Disconnect the furnace’s electricity completely.
You have two options for turning off the appliance: the switch or the breaker.

Step 2: Take apart or take out the furnace doors.

Step 3: Determine the location of the burners.
Depending on the furnace, different burner locations exist. They are easier to find because some are protected by a shielded box while others are not. Keep in mind how the burner was installed within the appliance before removing it.

Step 4: Either open the burner box or remove the burner bracket.
To remove the screws, you can use a power drill or a tiny wrench. In some instances, you might need to disassemble other parts of your appliance to get to the burner.

Step 5: Remove the furnace’s burners.

Step 6: Start cleaning the burners.
Use a brass brush to clean each burner’s surface. This may need to be done more than once, depending on how much dirt there is. Make sure that all of the trash has been removed. Finally, blow out any leftover debris and dust using compressed air.

Clean the Blowers

Hot air is brought into the house using fans or blowers. The heat is greatly diminished when they don’t work properly.

The ideal tool to use to clean the blades and motor housing is either a paintbrush or a toothbrush. The dirt that is still there can then be removed with a vacuum.

Make the Flame Sensor Clean

The heating system’s sensor is a safety measure. You can reach the sensor next to the panel opening once the power has been turned off. Avoid coming into contact with the porcelain base with your cleaning tools; only the metal rod component needs to be cleaned.

Sand the rod until the bare metal is visible by removing the carbon buildup. The residual dirt can then be removed with wire wool.

Examine and Clean the Flue Pipe in Your Furnace

Check the owner’s handbook before beginning with the flue pipe to determine if there are any special cleaning instructions for this component or if there are any acts that may void your unit’s warranty.

Find the vent pipe for your furnace after doing this. Before cleaning the pipes, it’s crucial to switch off the electricity.

After that, use a dust brush to remove any dust and dirt accumulations inside the flue pipes. Then, use a handheld vacuum to remove as much debris as you can.

Use a clear mat or soft towel to clean the area. Remember to clean the area around your vent pipes as well. Remove any obstructions to the airflow by trimming any branches or clearing the area of any items.

Has Lennox Ever Provided A Warranty?
