Why AC Coil Cleaning Is Important? Tips & Guide

Air conditioning systems are crucial in keeping our homes and workplaces comfortable, especially during the hot summer. However, regular maintenance is essential to ensure optimal performance and longevity of these systems. One aspect of AC maintenance that often goes overlooked is cleaning the coils. This blog will explore why AC coil cleaning is important and provide tips and guidance to help you keep your AC coils in shape.

Introduction

AC coil cleaning is a critical maintenance task that many homeowners and business owners neglect. The coils in an air conditioning system, namely the evaporator coil and condenser coil, are responsible for heat exchange. The evaporator coil absorbs the heat from indoor air and the condenser coil releases heat to the outdoor environment. When these coils become dirty or clogged with debris, their efficiency is significantly compromised, leading to various problems.

How AC Coils Work

To learn the importance of AC coil cleaning, it is important to have a basic informations of how these coils work. The evaporator coil inside the indoor unit cools and dehumidifies the air by removing heat. On the other hand, the condenser coil in the outdoor unit releases the heat absorbed from the indoor air. This heat exchange process allows the air conditioner to create a comfortable indoor environment.

Effects of Dirty AC Coils

When AC coils become dirty, several adverse effects can occur, impacting both the performance of the system and the indoor air quality. Firstly, dirty coils reduce the cooling efficiency of the air conditioner. As the coils become coated with dirt, dust, and grime, the transfer of heat is hindered, resulting in reduced cooling output and longer cooling cycles. This inefficiency compromises comfort and leads to increased energy consumption and higher utility bills.

Additionally, dirty AC coils contribute to poor indoor air quality. The accumulations of dirt and debris on the coils creates a breeding ground for mould, bacteria, and other allergens. When the air conditioner operates, these contaminants are circulated throughout the space, potentially causing respiratory problems and allergies.

Benefits of AC Coil Cleaning

Regular AC coil cleaning offers several significant benefits. 

Firstly, it improves the cooling performance of the air conditioning system. Clean coils facilitate efficient heat exchange, allowing the system to cool the air more effectively. This results in faster cooling, reduced strain on the system, and a more comfortable indoor environment.

Secondly, AC coil cleaning helps save energy. Clean coils enable the air conditioner to operate at its optimal efficiency, reducing the amount of energy required to cool the space. This result into lower energy bills and a more environmentally friendly operation.

Furthermore, AC coil cleaning enhances indoor air quality. Removing dirt, dust, and contaminants from the coils minimises the circulation of allergens and pollutants. This benefits individuals with allergies or respiratory conditions, as clean coils contribute to a healthier living and working environment.

Signs that AC Coils Need Cleaning

Recognizing the signs that AC coils need cleaning is crucial to prevent further damage to the system. One common indication is reduced cooling output. If you notice that air conditioner is not cooling the space as effectively as before, dirty coils could be the culprit. 

Additionally, frequent breakdowns or malfunctions may indicate the need for coil cleaning.

Another sign is to look out for is strange odours coming from the air conditioner. Dirty coils can produce unpleasant smells due to mould and bacteria accumulation. If you notice a musty or stale odour when the AC is running, it indicates that the coils need attention.

DIY AC Coil Cleaning

While professional AC coil cleaning is recommended for optimal results, there are some steps you can take to clean the coils yourself. Before attempting DIY maintenance, ensure you have the necessary tools, such as a soft brush, a fin comb, a coil cleaner, and a vacuum cleaner.

Start by turning off the power to the air conditioner. Next, remove any debris or vegetation that may have accumulated around the outdoor unit. Carefully clean the coils using a coil cleaner, following the manufacturer’s instructions. Rinse the coils thoroughly and let them dry completely before reassembling the unit and turning it back on.

Professional AC Coil Cleaning

While DIY cleaning can be effective to a certain extent, professional AC coil cleaning is highly recommended for optimal results and to avoid any potential damage. Professional technicians have the expertise and specialized equipment to thoroughly clean the coils, ensuring the removal of all dirt, grime, and contaminants. Moreover, they can identify any underlying issues requiring repair or maintenance.

Hiring experts for AC coil cleaning offers several benefits. Professionals can assess the system’s overall condition, identify potential problems, and provide appropriate solutions. Additionally, they can perform a comprehensive cleaning that reaches all areas of the coils, maximizing the efficiency and lifespan of the air conditioning system.

How Often Should AC Coils be Cleaned?

The frequency of AC coil cleaning depends on various factors, such as the environment, usage, and the presence of pets or smokers in the space. As a general guideline, cleaning the coils at least once a year is recommended. However, more frequent cleaning may be necessary for dusty or high-pollution areas or spaces with heavy usage.

Regular maintenance, including coil cleaning, can significantly extend the air conditioning system’s lifespan and ensure optimal performance throughout its service life. Consult the manufacturer’s guidelines and consider professional advice to determine the ideal cleaning frequency for your situation.

Conclusion

AC coil cleaning is a crucial aspect of air conditioning maintenance that should not be overlooked. Keeping the coils clean can improve cooling performance, save energy, and enhance indoor air quality. Whether you choose to perform the cleaning yourself or hire professionals, regular maintenance will contribute to the longevity and efficiency of your air conditioning system.
