The Importance of Regular AC Maintenance: AC Service

Keeping Your System Running Smoothly All Year Round

In order to keep the AC running all year round, it is important to take care of it regularly. The main action that every AC owner should follow, is to check on and regularly replace the system’s filters. In this blog, we will discuss some important factors related to the maintenance of your AC system. And understand how you can provide an effective AC service, to your system by professionals or by yourself.

Regular AC maintenance

Regular check-ups of your system will help you track the dirty filters and change or clean them. This is because the AC filters tend to collect dust and other various particles that lower the efficiency of the AC work. Eventually, if the filter is not changed or taken care of, it harms the system, since the clogged filter doesn’t let in enough air to the system and causes its malfunction.

Here’s how it happens. With the obscured airflow, the air bypasses the filter and deposits dirt right into the evaporator coil, impairing the coil’s heat-absorbing capacity. Furthermore, the clean filter absorbs a minimal amount of air and reduces energy consumption.

Typically, the AC filters are positioned in the walls, ceilings, or the conditioner. The central air conditioners usually have the filter located around the return duct’s length.

The types of AC filters

AC filters are an integral part of any HVAC system, which stands up for Heating, Ventilation, and Air Conditioning.

There are many types of AC filters, that are diverse in sizes, materials, and designs. Each of these has one single purpose, which is to meet and maintain various filtration needs. Thus, let’s get acquainted with some types of filters, to understand what suits your AC system.

  • Fiberglass filters: These are the most popular and affordable options among all the AC system filters. They have layered fiberglass strands that are made to keep the dust and debris away from the inside of the house. They protect the house from large particles, however, they are not suited for smaller ones, including allergens.
  • Pleated filters: These types of filters are made of polyester or cotton paper. They come in a pleated design the purpose of which is to have a larger surface area and capture airborne particles. Compared to fiberglass filters, pleated ones provide better filtration and are able to trap even smaller particles, for example, pollen, pet dander, and mold spores.


  • High-efficiency particulate air (HEPA) filters: It is safe to say, that HEPA filters are the gold standard among AC filters. They are being produced from tightly woven glass fivers and are able to trap 99.97% of earlobe particles even the ones of 0.3 microns in size. They are a preferred choice especially for the ones with allergies and respiratory conditions, since they effectively clean the air from allergens, bacteria, and various viruses.
  • Washable filters: These are also called reusable filters and are made of foam or aluminum mesh. They can be cleaned and reused multiple times, which is helpful both financially and environmentally. However, they offer less effectiveness compared to regular AC filters.
  • Activated carbon filters: These filters have highly porous activated charcoal and clean the air from odors, gases, and volatile organic compounds. They are widely used with other filters and are able to improve the quality of air in areas with high levels of smoke, cooking, odors, and chemical fumes.

Regardless of the filter type, they all need regular inspection and replacement in order to keep the AC system in check. Why? Because in case the filter is dirty or clogged, the system reduces its efficiency, and over time develops malfunctioning. It is recommended to seek professional help from an AC service company, to clean or replace the filter, as well as get the system checked.

The frequency of filter replacement

There are a few factors that influence the frequency of AC filter replacement, for example, the filter type, usage patterns, environmental conditions, manufacturer’s recommendations, and so on.

Starting from the filter type. Some types, such as disposable ones and fiberglass ones, have a limited lifespan and require to be replaced every now and then. Washable filters can be used longer due to their ability to be washed and reused. The HEPA filters serve longer, though, they still need to be replaced in order to maintain optimal performance.

In some areas, air pollution is comparably higher, for example, in construction areas, or kitchens. This is a huge factor that can decide the filter type able to capture more pollutants from the air.

And last but not least, it is highly important to follow the system’s manufacturer’s guidance. This will help decide the exact filter type supported by the system, the factors to consider when cleaning them, and so on.

Ensuring the smooth operation of your AC system

Ensuring the smooth operation of your AC system involves more than just regular filter replacement. It’s essential to conduct comprehensive maintenance checks to address any potential issues before they escalate. This includes inspecting the ductwork for leaks, assessing the thermostat’s accuracy, and lubricating moving parts to prevent friction and wear. By addressing these aspects of your AC system, you can enhance its efficiency and prolong its lifespan.

Additionally, maintaining proper airflow is crucial for optimal AC performance. Ensure that vents and registers are free from obstructions and dust buildup, allowing air to circulate freely throughout your home. Blocked vents can lead to uneven cooling and strain on your AC system, resulting in increased energy consumption and potential breakdowns. Regularly vacuuming and dusting vents can help maintain consistent airflow and improve indoor air quality.

Regular professional maintenance

Regular professional maintenance from an AC service company is highly recommended to ensure the longevity and efficiency of your AC system. Experienced technicians can identify and address any underlying issues. That may affect performance, such as refrigerant leaks, electrical faults, or compressor problems. Professional maintenance can also help prevent costly repairs. And extend the life of your AC system, ultimately saving you time and money in the long run.

In addition to professional maintenance, homeowners can take proactive steps to optimize their AC system’s performance. This includes scheduling regular tune-ups, adjusting thermostat settings for energy efficiency, and investing in programmable thermostats or smart HVAC systems. By implementing these measures, you can maximize comfort, minimize energy consumption, and reduce the risk of unexpected breakdowns or malfunctions.

Outdoor Condenser Units

It’s also important to keep outdoor condenser units clean and free from debris, such as leaves, grass clippings, and dirt. Regularly inspecting and cleaning the condenser coils. Fan blades, and surrounding area can prevent airflow restrictions and ensure efficient heat transfer. Additionally, trimming vegetation and maintaining a clear space around the condenser. Unit can optimize airflow and prevent overheating during peak summer months.

By prioritizing regular maintenance and taking proactive measures to optimize your AC system’s performance. You can enjoy reliable cooling comfort throughout the year. Whether you choose to perform DIY maintenance or enlist the help of a professional AC service company, investing in the care of your AC system is essential for long-term performance and efficiency.


Regular AC maintenance is the main key to keeping the system running all year round. By inspecting the system’s and filter’s condition, you will able to detect any obstacle that will eventually influence the smooth work of your AC system and remove it.
