Looking to Replace Your Air Conditioner’s Evaporator Coil?
In a central air conditioning system, the cold chemical refrigerant flows through the evaporator coil. The refrigerant absorbs heat from your home’s air, and moisture condenses out of the air when it comes into contact with the cold coil. A crack, corrosion, or rust might necessitate a replacement of the evaporator coil. Here’s what you need to know about replacing this critical part of your central air conditioning system in Buffalo Grove, IL.
Reasons to Replace the Evaporator Coil
You might consider replacing the coil if your air conditioner has lost efficiency and no longer effectively cools your home. Erosion of the coil, which eventually leads to a coolant leak, is another common reason to replace this part. Some coil cleaners cause corrosion on the exterior, which also leads to the weakening of the coil. Rarely, the coil may crack as a result of an impact, corrosion, rust, or too much pressure from the coolant.
Match the Coil Type
If you’re looking to replace the evaporator coil, you’ll need to consider the age of your central cooling system. Units produced before 2010 typically use R-22 as the coolant. Also known by the brand name Freon, this coolant is no longer produced due to EPA regulations. The coil type must match the type of coolant used in the system, or the system won’t work. For older air conditioners, you may be better off replacing the whole system instead of investing in a new coil.
Consider the SEER
You’ll also need to consider the seasonal energy efficiency ratio (SEER) when replacing an evaporator coil. Today’s minimum SEER is 14. If your air conditioner has a SEER of 10 or 12, a new coil won’t match the rest of the system. This could cause ineffective cooling, high electricity bills and extra wear and tear on the compressor.
