Any HVAC system requires regular maintenance, but which HVAC system parts need to be checked each time? Find out in this guide.

Which HVAC System Parts Need to Be Checked?

Have you noticed an inefficient air conditioner, furnace, or air filtration system? If you’re searching for a breakdown of the HVAC system, you’ve come to the right place. Information on all aspects of the heating and cooling system is on this comprehensive list.

Don’t slow down production in your building by not maintaining your system. From the units to the HVAC system parts, everything needs to be inspected, replaced, and cleaned.

Find signs that your system is degrading on this list of HVAC components.


Air Filters

The air filter works like a shield, trapping potential contaminants and debris in the air before they get into the system. If not changed regularly, the air filter can become clogged and can lead to poor airflow. 

This, in turn makes the HVAC maintenance system work harder and less efficiently. This can result in higher power bills and the possibility of repair bills. Making sure to check the air filters regularly is a crucial part of maintaining a well-functioning HVAC system.


The evaporator coil should be checked for signs of corrosion, dirt, blockage, or other damage.

Other electronic components, such as the expansion valve, solenoid valve, and condensate drain line should also be checked regularly to ensure they are functioning correctly.

It’s also important to periodically perform an HVAC system check on the refrigerant level and inspect the ductwork for signs of wear or damage. 

Condenser Coils

The condenser coil is responsible for removing heat from the air. If it is not working properly, it can cause the system to malfunction. To check the condenser coil, one should inspect the area around the coil for dirt or debris.

This may be blocking the airflow. It is also necessary to check for any signs of damage or corrosion and to ensure that the coil is tightly secured.

The insulation and fan blade should be checked for any signs of wear, and if there are any signs of wear, the coil should be replaced. 

Blower Motors

This important component of the system is responsible for providing the unit with the necessary airflow to keep the space at the desired temperature. It’s important to regularly inspect the blower motor to ensure that it is in good working condition.

This can be done visually by checking for any debris that may be stuck in the motor or its blades, as well as listening for any strange noises coming from the motor.

If any issues are found during the inspection, it’s best to contact a professional for expert preventative maintenance plans. Get the best assistance in replacing the part to ensure proper unit operation.
