Three Signs That Evaporator Coils Need Cleaning

Why Get Professional Evaporator Coil Cleaning?

Most home air conditioners have two independent coils, one in the indoor unit and one in the outdoor unit. The evaporator coil is the name given to the inside coil. The evaporator coil includes liquid refrigerant, which absorbs heat and changes into gas to chill the air inside. 

Dust, pollen, and other airborne contaminants are often drawn to the evaporator coils. If the air filter is dirty or there is more dust in the area than usual, such as after a home renovation project, these coils may get dirty quicker. The evaporator coils may stop adequately functioning when excess dirt and debris adhere to them. This accumulation of debris can result in a 40% increase in energy consumption and a 30% reduction in cooling capability. 

The HVAC system may suffer long-term effects from delaying AC coil cleaning, including malfunctions, increased wear and tear, or other problems. Keep reading for three signs that evaporator coils need to be cleaned.

Dirty Evaporator Coils Cause Lower Cooling Functions

Dirty evaporator coils cause reduced heat transfer and energy efficiency. Everything will become hotter as a result of these problems. Mechanical components and electrical systems should not be exposed to excessive heat. Parts also deteriorate quicker as a result of this. 

Remember, the refrigeration system will always work at higher temperature pressures when the outside temperature is high. The compressor will be under a lot of strain as a result. Dirty coils force the equipment to work much harder and significantly reduce the system's efficiency, often resulting in lower cooling capability.  

Dirty cooling coils can also impact indoor air quality. Removing moisture from the air is one of the primary purposes of the AC system. The dehumidification procedure will be adversely affected by dirt and debris on the AC coils. Additionally, water, dirt, and germs are all favorable environments for unwanted biological development and could increase the amount of mildew and mold.

Dirty Evaporator Coils Can Cause Frost

Another sign evaporator coils need to be cleaned is when the evaporator coil or the outside of the unit freezes or is covered in frost. Insufficient airflow is the leading cause of frozen evaporator coils. This is frequently brought on by a dirty or clogged air filter, a backed-up drain, a slow fan, or a dirty evaporator coil. The air conditioner can’t effectively defrost if it can’t keep itself warm enough to prevent ice from forming and moisture around the unit freezes. 

Dirty Evaporator Coils May Keep the AC Running Too Long

One of the most common causes of the air conditioning unit running too long is the evaporator coils being dirty. Mud, dirt, or grass clippings all obstruct the airflow to the unit. Blocked evaporator coils decrease efficiency and may cause the unit to run nonstop to reach the desired temperature.

Homeowners should hire a professional to examine their systems. They will inspect the evaporator coils during the visit and clean them. Professionals have found that the evaporator coil is prone to dust or dirt buildup because it is constantly exposed to airflow circulated by the blower. 

The crucial heat transmission from the air to the refrigerant is less effective when airborne particles stack up on the coil surface. As a result, the system runs longer cycles to maintain thermostat settings, leading to poor cooling performance and increased expenses.
