Do your evaporator coils need cleaning? At times the evaporator coils can become full of dirt and debris which will interfere with your HVAC cooling systems. Evaporator coils require cleaning in order for the air conditioner to create cool air. Absolute P&M Services will share how evaporator coils gets dirty as well as what signs to look for when your coils need cleaning.

Evaporator Coil Location & Function

The evaporator coils are located in the area designated as the cold side of the air conditioning system. The evaporator coils sit just behind the access panel in the air handler. The job of the evaporator coil is to absorb the heat from the air with the help of the refrigerant. During this cooling process, condensation develops on and around the evaporator coils. These tiny droplets of water make it easy for dirt and other particles to stick to the evaporator coils. Over time more and more dirt and gunk builds up on the evaporator coils to the point they no longer can absorb the heat from the air.

Symptoms of Dirty Evaporator Coil

When the evaporator coils get dirty, it can have a number of effects on the cooling system. One of the first signs the coils are dirty is when warm air blows through vents instead of cool air. This is because the coils are too dirty to do their job. When the evaporator coils fail to cool down the air, it can have a domino effect on the rest of the air conditioning system. Since the air isn’t cooling down, the temperature inside the home remains warm. The thermostat will trigger another cooling cycle until the right temperature is met. When the air never reaches the cooler temperatures, the air conditioner continues to run more frequently and in longer cycles, causing overheating and premature wear. When the evaporator coils are dirty it is important to clean them before they can cause serious damage to the rest of the air conditioning system. This is why it is important to detect signs that the evaporator coils are dirty. Some of the major signs that the evaporator coils are dirty are:
• Warm Air Blowing
• Longer Running cycles
• Increased Power Bill

How to Clean Evaporator Coil

When the evaporator coils need to be cleaned, many people consider it a DIY job and any homeowners will attempt to clean the coils themselves. You can clean evaporator coils yourself, but it is strongly recommended to have the coils cleaned by a professional. The evaporator coils have thin metal blades that create the coils. If these thin blades get bent or damaged the coils will not be able to remove the heat out of the air properly. Additionally, for those who have a warranty on their air conditioning system and you do your own evaporator coil cleaning and damage the coils, the warranty can be voided. By having the evaporator coils cleaned by a professional HVAC service the warranty will not be void even if damage occurs. A professional HVAC service can clean the coils properly and ensure your air conditioning system works at top performance.
