Improve the AC by Unleashing Its Full Potential 

Air conditioners in the area have to work hard all summer long to keep everyone cool and comfortable. Over the years, it has been common for air conditioners to lose efficiency. As the air conditioner gets older, it costs more and more money to run each year, likely leaving home feeling warm and humid. 

Luckily, there is a simple way to restore lost efficiency to an air conditioner and slow down the aging process of AC systems. Springtime AC maintenance is crucial for homeowners who want to get the most from their air conditioners. This quick article focuses on one aspect of AC maintenance: coil cleaning. Coil cleaning may be the most crucial step in AC maintenance. Here's what that means. 

What Do Evaporator Coils Do?


For most people, all they want to know about an air conditioner is if it blows cold air. But where does the cold air come from? Knowing some of the basic principles of how an AC works can help homeowners troubleshoot their system and appreciate its complexity. 

To make cold air, the warm air in the house is blown across a very cold coil called the "evaporator coil." The evaporator coil is cold because it has refrigerant that expands and pulls heat out of the warm air being blown across it. Over time, the evaporator coil can become fouled with dander and dust. This limits the amount of heat that one can pull out of warm indoor air, so the whole system loses efficiency. 

Where are Condenser Coils Located?

coilThe other half of the air conditioner's coil system is challenging at work outside the house. Once refrigerant absorbs heat from the evaporator coil, the heat is "pumped" outside, where it is blown off by fans that cool the condenser coil. This is why the air coming from the condenser unit outside is always hot; that's the heat from home's inside!

The condenser coil is very sensitive to dirt and debris that block its airflow as the evaporator coil. Because air is constantly moving across it, it can get filthy in a cooling season. Additionally, it has no filter to keep grime from getting into it. 

Don't Forget the Rest of the AC Maintenance

Professional AC coil cleaning is a common part of any good AC maintenance program. During the coil cleaning process, a technician will use chemicals to clean dust and grime built up on the air conditioner's coils. The inside coil takes a foaming cleaner that sits on the coil and gets washed off as moisture condenses on the coil while the AC cycles. 

The outdoor coil will probably get hosed off once it has been cleaned. The cleaning result is a highly-efficient air conditioner that will save the owner money in the coming season. In addition to coil cleaning, AC maintenance will cover things like:

  • Lubrication of moving parts
  • AC filter changes
  • Cleaning of the blower wheel
  • Topping off refrigerant levels
  • Visual and electrical inspection
