AC Coil Replacement

The evaporator coil is the central component of an air conditioner. This system uses a blower to flow cool air through your home or business. However, an ac coil can fail after many years of use and cause costly damage if you don’t replace it in time.

An ac coil replacement costs more than just the price tag on the part itself. We will discuss all factors that affect its total cost below, so you know what to expect when replacing an ac coil, yourself, or hiring someone else to do it for you.

Factors That Affect Evaporator Coil Replacement Cost

Here are some things that may affect how much does an ac coil replacement cost:

The evaporator coil’s initial cost generally ranges from $65 to $125 for residential homes and up to $1000 for industrial business premises. However, the evaporator coil replacement cost rises depending on the above factors.

How Evaporator Coil Works 

The AC evaporator coil is designed to control the distribution of air in the building by transferring heat from a liquid to a gas. The condenser coil is responsible for removing the latent heat of the refrigerant gas, which then causes a refrigerant vapor and liquid to form. Heat will be transferred to the cold air outdoors through this process. The heat is then transferred back indoors when it moves into the evaporator coil, which cools the refrigerant vapor back down into a liquid in order for it to cool again.

When You Will Need AC Coil Replacement

AC coils are made of aluminum and copper, which tend to corrode over time. The coil is also exposed to dust, lint, and dirt that can lead to coil failure. If you notice your coil dripping or not cooling properly, then coil replacement might be necessary. 

Moreover, you may need a new coil for HVAC when you notice:

  • High utility bills
  • High pitched squealing or humming
  • A strong musty odor or visible coil leaks
  • A coil that is corroding, feels loose on the air handler or vibrates excessively.
  • Another indication that you may need a coil replacement is if you have already turned the thermostat down but still find your home feeling warm. 

What Can Cause Coil Failure?

Many other factors can lead to coil failure like:

  • Improper coil installation
  • Mold and mildew accumulation
  • Broken coil fins from age
  • The coil freezing and blistering due to improper refrigerant charge
  • Low-quality coil options
  • Dust and dirt accumulation

Maintaining your HVAC system ensures it is getting the most out of energy and working to its fullest potential. HVAC coil inspections should be performed every year in order to prevent coil corrosion, coil failure as well as other issues.
