How Much Does an Evaporator Coil Cost?

November 4, 2019

An evaporator coil is a key component of an air conditioning system, and replacing it can be a challenging and expensive proposition. Understanding the role that the evaporator coil plays in your air conditioning system, the additional parts and pieces that are necessary for a quality installation and the overall costs can help you make an informed decision.

What is an Evaporator Coil?

The evaporator coil is one of three major components of your air conditioning system. It is located inside the air handler or attached to the heater. The evaporator coils main function is to absorb the heat from the air inside the home. The heat is than transferred to the condensing unit and released outside.The two most common types of evaporator coils use in the Houston area are A-shaped box coils and the traditional horizontal slab coil designed for an attic installations.

We have found slab coils to have a lesser propensity to leak freon overtime and to be substantially more reliable. They are also easier to maintain because of the ability to provide in duct access doors for improved serviceability and regular cleaning tasks. A-shaped coils are not as serviceable and in most cases cleaning will require the complete removal of the coil. A coils are used in a great number of newly built homes in the Houston area because it is cheaper to install an air conditioning system in this manner, but overall system performance is compromised and life expectancy of boxed A-coils is half that of its slab counterpart.

What Is Needed For A Quality Installation?

Whether you’re replacing just your evaporator coil or the entire heating and air conditioning system, you’ll want to make sure you’re relying on professionals to do the job right. A/C repairs and evaporator replacements are not an amateur or do it yourself proposition. It’s important to protect your home from water damage that can be caused by the faulty installation of the evaporator, the drainage system to the evaporator, or the inevitable drain blockage of the system.

In most cases the replacement of the evaporator coil will require the replacement of the interconnecting ductwork i.e. “Transition and Plenum”, an auxiliary drain pan, and possibly the replacement of the main drainage system. The coil will need to be installed in a manor to allow for proper drainage and will need safety protection to protect your home from water damage in the event of drain failure. If the installation is in and attic, it’s important to install an auxiliary drain pan that has a separate drain under the evaporator coil. This extra drain pan can help you avoid problems if your primary drain malfunctions. Finally, be sure to select a reputable brand that provides a good warranty as well as a licensed, professional HVAC company that has a proven track record of doing this kind of work and standing behind the warranty over an extended period of time.
