Which AC Unit Parts Require the Most Maintenance?

AC unit parts

As the seasons change into fall and then winter, we are frequently tasked with home maintenance tasks that are designed to make the colder months comfortable. One of the essential tasks includes maintaining the air conditioning unit which keeps us cool in the summer and warm in the winter. The better maintained it is, the more enjoyment you will get from your home. In this blog, we will zero in on the importance of maintenance, focusing on the specific parts that need it most. Read on to learn how you can prepare your home for this year’s fall and winter. 

Make Sure to Maintain These AC Parts

Though it is important to maintain the entire HVAC system as a whole, there are some parts that require attention more often than others. Proper maintenance of the AC unit parts outlined below will ensure the following:

  • Proper indoor air quality
  • Optimal energy efficiency levels
  • Consistent temperatures 
  • Reliable unit
  • Less need for repairs
  • Longer lifespan of the unit

Air Filters

One of the most critical parts of the air conditioning unit is the air filter. Normally, there is a set of two filters for an average-sized home. They tend to accumulate dust, dirt, and debris over time, which leads to a decrease in airflow through the system. As a result, you won’t get those heating or cooling temperatures you need throughout the home. 

We recommend checking your air filters every one to three months, depending on how much you use the air conditioning unit. 

Condenser Coils

The condenser coils are found in the outdoor unit of the AC. The role of these AC unit parts is to dissipate heat from the refrigerant. As with many other parts, these coils become dirty with dust and debris. If the dirt isn’t cleaned off the condenser coils on a regular basis, the heat transfer will not be as efficient as required. Luckily, you can get away with cleaning the condenser coils just once a year and ensure that your AC runs as smoothly as possible. 

Evaporator Coils

The evaporator coils are located in the indoor unit and are responsible for cooling the air. Like condenser coils, they can accumulate dust and dirt, leading to reduced efficiency. Cleaning the evaporator coils annually helps ensure proper cooling and airflow.

Drainage System

The air conditioning system is built with a drainage system that removes condensate that is produced during the cooling process. As the drainage system works to perform this essential task, it is prone to becoming clogged with algae, mold, or debris. These accumulations cause water leakages which can severely damage the unit. The best way to avoid this problem is by inspecting and cleaning the drainage system. This AC unit part is always looked over during a maintenance service, providing the opportunity for that necessary cleaning to take place. 

Fan and Fan Motor

If the fan or fan motor do not work, the airflow and overall system performance will be hindered. Thus, it is essential that both of these parts are periodically cleaned and lubricated. Doing so about once a year will allow you to experience those warming or cooling temperatures you desire, depending on the season outside. 

Electrical Components

It is not a secret that all air conditioning units on the market today are mostly made with electrical components that have their own maintenance needs. Capacitors, contactors, and relays all wear out with time and must be repaired when necessary. When an AC repair tech inspect the unit, they ensure to clean and replace them when needed, ensuring a reliable system for the homeowner to use. 

Refrigerant Levels

Another vital AC unit part is the refrigerant fluid flowing through the coils. This fluid is responsible for cooling air in the AC system. Over time, refrigerant levels can deplete due to leaks or other issues. If you notice any such leaks, notify your local AC repair tech and allow them to investigate the underlying issue. Inadequate levels of refrigerant will affect the cooling and airflow performance of the AC.
