The Importance of AC Coil Cleaning

Understanding HVAC: Condensers vs. Evaporators

In the realm of HVAC (Heating, Ventilation, and Air Conditioning) systems, condensers and evaporators stand as fundamental components.

Understanding the Significance of AC Coil Cleaning

In the scorching heat of Texas, a well-functioning air conditioning system is not just a luxury but a necessity. However, many homeowners overlook a crucial aspect of HVAC maintenance – coils cleaning. 

What are AC Coils, and Why Do They Need Cleaning?

AC coils, also known as evaporator and condenser coils, play a vital role in the cooling process. The evaporator coil absorbs heat from indoor air, while the condenser coil releases it outside. Over time, these coils accumulate dirt, dust, and debris, hindering their efficiency.

Dirty AC coils can lead to several issues, including reduced cooling efficiency, increased energy consumption, and even system breakdowns. When dirt builds up on the coils, it acts as insulation, preventing efficient heat transfer. As a result, the system has to work harder to achieve the desired temperature, leading to higher energy bills and premature wear and tear.

Reduced Cooling Capacity

If the cooling power of an AC system appears diminished, it might indicate that the ac evaporator coil is coated with grime. The accumulated dirt hampers the ability of the coil to transfer heat, preventing it from cooling the air efficiently. Therefore, if the air blowing through your vents feels warmer than before, it’s likely time to clean the coils.

The HVAC System Runs Longer

If your air conditioning unit seems to be operating for extended periods, it might be a sign that the evaporator coils are coated with grime. When the coils are dirty, they can hinder the efficiency of heat exchange, leading to a less effective cooling process. As a result, your AC will have to exert more effort and operate for a prolonged time to achieve the desired temperature, compared to its performance with clean, fully functional coils.

Your Coils Have Frost

If you see that your evaporator coil is starting to accumulate frost, this may indicate that the coil is soiled to the extent that it risks malfunctioning. The frost indicates that moisture is condensing on the accumulated grime, and as this frost layer thickens, it will ultimately halt the transfer of heat completely, leading to the failure of the cooling system.

Alternative Reasons for Obstructed Airflow in Your Air Conditioning System

Other issues besides a filthy evaporator coil can result in obstructed airflow within your air conditioning system. Recognizing these possible complications is crucial for effectively diagnosing your HVAC system and identifying the required fixes. Additional causes of airflow obstruction are:

1. Blocked Air Filters: Should your air filters become obstructed with grime and rubbish, they may present issues similar to those of a clogged coil. Whenever you experience diminished efficiency in cooling, your initial step should be to inspect your air filter. Also, ensure you routinely examine your filter during every season.
2. Incorrectly Positioned Air Filter: There are instances where an air filter can be improperly installed so that its arrow faces opposite to the direction of the airflow. If this occurs, the filter’s components may get ripped and accumulate on the coil, leading to obstruction and blockages in the system.
3. Airflow Obstructions: Unnoticed gaps in your air ducts or other kinds of air leaks within your system can hinder the flow of air, leading to reduced efficiency in air distribution. This will lead to an outcome akin to the issue experienced with a clogged evaporator coil. Damaged fins on the coils of an air conditioner, whether on the evaporator or the condenser side, can lead to restricted airflow. However, it is only when the damage is significant that this can result in reduced performance and the formation of ice on the coils.
4. Unclean Blower Fan: When your air handler’s blower fan accumulates a thick layer of dust, particles, and filth, the amount of air that moves over the evaporator coil diminishes. A decrease in airflow may result in the coil freezing over and cause operational issues with your system.

Symptoms of A Dirty Condenser Coils

1. Your air conditioning system is failing to maintain a cool temperature in your house. If a condenser coil in an air conditioning unit becomes coated with grime, it can hinder the unit’s effectiveness in delivering chilled air. As dirt builds up on the coils, it creates an insulating layer that obstructs the interaction between the airflow across the condenser and the heat held in the refrigerant circulating through it. This means that it becomes harder for heat to move from the condenser coils into the surrounding air, leading to a cooling system that doesn’t work as well. Should you observe a drop in the system’s ability to cool, it’s possible that your condenser is in need of cleaning.
2. The unit’s energy efficiency is greatly reduced. One indication that your condenser needs cleaning is a noticeable increase in your energy bills. A condenser coil covered in dirt causes the air conditioning system to lose its efficiency. If the coil is dirty or blocked, it forces the system to exert more effort to maintain the same cooling performance. Decreased performance forces the system to exert more effort, leading to greater electricity consumption and consequently, increased energy expenses. Should you notice your utility bills are elevated beyond the norm, it might be necessary to check your condenser.
3. Your air conditioning unit requires regular and costly maintenance. An unclean condenser coil makes the system exert more effort, leading to quicker deterioration. Tackling the issue of a soiled condenser coil promptly can prevent major consequences; still, the extra stress inflicted on your air conditioner by dirty coils heightens the risk of system breakdown and expensive maintenance. Should your unit often need fixing, it’s advisable to check the coils.
4. Your AC Starts Leaking Regularly. Detecting leaks in the condenser and its coils may be challenging, yet such issues can impact your whole system. The condenser coils are responsible for moving the refrigerant and expelling heat from the air. Minor damage from grime or foreign material can result in leaks. A condenser leak will lead to a decrease in refrigerant amounts, impairing your system’s capacity to chill the air effectively. Should you observe a decrease in refrigerant levels when there should not be one, it is possible you have a leak that requires fixing.

Benefits of AC Coil Cleaning

1. Improved Energy Efficiency: One of the primary benefits of AC coil cleaning is improved energy efficiency. By removing dirt and debris from the coils, the system can operate more efficiently, reducing energy consumption and lowering utility bills.
2. Extended Lifespan of the System: Regular AC coil cleaning can also extend the lifespan of the system. When the coils are clean, the system doesn’t have to work as hard to maintain the desired temperature, reducing wear and tear on components and prolonging the system’s lifespan.
3. Better Indoor Air Quality: Dirty AC coils can harbor mold, bacteria, and other allergens, compromising indoor air quality. By cleaning the coils regularly, homeowners can ensure that their indoor air is clean and healthy, reducing the risk of respiratory issues and allergies.

How Often Should AC Coils Be Cleaned?

The frequency of AC coil cleaning depends on several factors, including the environment, usage patterns, and the presence of pets. As a general rule of thumb, AC coils should be cleaned at least once a year. However, in areas with high humidity or heavy pollution, more frequent cleaning may be necessary.
