A Complete Professional Furnace Tune Checklist With Easy Steps


Every heating system requires yearly professional maintenance to function correctly throughout winter. Professional maintenance is required for all furnaces and boilers once a year; heat pumps require it twice yearly because they provide heating and cooling. 

Professional service is recommended for furnace users to maintain the system’s efficacy and functionality. A Furnace Tune Up Checklist should be completed once a year to keep the furnace in good working order. If you don’t do routine maintenance, you can miss out on essential coverage that might save you money and time.

You can take a few actions to keep your HVAC in good working order as a furnace user. Continue reading to learn more about inspecting and repairing your furnace.

What to Expect at an Annual Furnace Inspection

A Furnace Tune-Up Checklist will cover all the simple DIY activities and some more sophisticated ones that should be left to the professionals. Here are some of the maintenance tasks that have to be completed.

Remove the Oil and Bearings

Cleaning and lubricating HVAC components are essential to extending their life and preventing failures.

Cleaning The Air Filter is Important 

Regularly cleaning the air filters will significantly improve airflow and prevent impurities from entering the interior air.

Make Sure The Thermostat is Working Properly

Check the thermostat for functionality and accuracy at least once a year. You can ask your furnace professionals to recalibrate your thermometer to assist you in saving money on energy.

Cleaning Blowers Components

Because the blower is the most significant component of the furnace, it is critical to clean the blower components to keep the inside air clean. As a result, cleaning them out is critical to ensuring that their performance is maintained.

Check the Flame and Combustion

Your furnace technician will turn them on and off the furnace to examine the ignition and flame condition. If the pilot valve is not operating properly, they can replace it or change the ignitor accordingly.

Examine the Air Circulation

It is critical to inspect the vents for cleanliness for the furnace vents to function properly. Because the furnace vents channel gas away from your house via the flue pipe, the HVAC professionals will check for garbage, leaks, and slopes to ensure optimum ventilation. They will clean up any obstructions in your furnaces, such as rust and water streaks.

Keep Moving Parts Lubricated

Keeping the furnace well-lubricated will ensure that it makes no loud noises while operating and maintains its energy efficiency.

Examine the Belts for Any Cracks

Every belt in a furnace requires some flexibility, but more is needed to guarantee that it will remain crack free. If not maintained, it may develop cracks. Though the fractures in the belt may be visible immediately, a comprehensive inspection is required to ensure that even the slightest damage is identified and repaired.

Drains and Traps Should Be Flushed

During the inspection, the HVAC specialist will flush the furnace’s drains and trap areas and look for leaks. Every furnace system includes at least two drains that link to the unit’s trap. They aid in the cleaning of the heat exchanger and vent locations. Flushing the drains and traps will assist in locating any obstructions or leaks.

Check Whether The Electrical Connections Are Secure

It is possible for the wiring connecting to the furnace to get slack at times, particularly in the heating components, so tighten all connections to prevent short circuits and gas leaks.

The Manifolds Should Be Tested For Gas Pressure

The manifold is where the gas flows from the main burner; therefore, ensure that the pressure is in the correct flow to avoid any gas flow problems.

Examine the Interior of The Vestibule

Because the vestibule acts as an airlock between the interior of the furnace components and the outer door, it must be kept clean to prevent contamination and poor performance.

Panels Must Be Tightened and Polished

The panel units should be snug in position because squished panels might impede energy flow and generate creaking noises when running, which will, in turn, cause system difficulties. A faulty front panel could potentially put the furnace at risk of creating carbon monoxide.


Always perform a furnace checklist once a year since this can lead to various costly complications. Schedule a professional service for your furnace system to improve its performance, efficiency, and comfort. It not only saves money, but it also saves on heating and repair expenditures. Professional assistance will ensure that your furnace operates more efficiently than ever before.
