The AC Evaporator Coil plays a crucial role in the proper functioning of an air conditioning system. As an essential component, it is responsible for cooling the air that circulates within the unit, allowing us to enjoy the comfort of a cool indoor environment during scorching summers. However, like any mechanical part, the AC unit coil is subject to wear and tear over time, leading to potential malfunctions. In this blog, we will explore the importance of the HVAC Evaporator Coil, reasons why its replacement might become necessary, and delve into the HVAC coil replacement cost associated with this essential repair.
Let us delve in & find out what are AC evaporator coils are & is it worth replacing evaporator coil.
Understanding AC Evaporator Coils
The AC evaporator coil is a vital component of your central air conditioning system. Positioned inside the air handler of the indoor AC unit, it circulates cool liquid refrigerant from the compressor. As indoor warm air passes over the coil, it gets cooled and returned to your home. Meanwhile, the now-hot refrigerant is expelled outside, initiating the cycle once more. This efficient process ensures your home stays comfortably cool during hot weather. Regular maintenance and cleaning of the AC unit coil are essential for optimal AC performance.

Is it worth replacing evaporator coil?
Replacing coils in air conditioner can be worthwhile under specific circumstances. If your AC system is relatively new, and the evaporator coil is the only major issue, it might make sense to replace it rather than investing in a whole new unit. However, if your AC is aging, has frequent breakdowns, or other components are failing, it may be more cost-effective to replace the entire system. Consulting with a professional HVAC technician is crucial to determine the best course of action based on your specific situation and budget.
The Average Cost to Replace AC Evaporator Coil
Replacing central air conditioner evaporator coil typically costs between $600 and $2,000. The coil itself ranges from $180 to $1,600, and professional installation adds an additional $400 to $1,000. The total HVAC coil replacement cost depends on several factors:
Brand: High-end air conditioner brands may have a higher ac coil replacement cost.
Style of Coil: The shape and encasement of the HVAC evaporator coil affect the price.
Unit Size: Larger air conditioners require larger evaporator coils, increasing the cost to changing evaporator coils.
AC Evaporator Coil Replacement Cost Breakdown
Replacing evaporator coil in air conditioners is an essential maintenance task that ensures your air conditioning system operates efficiently. However, it's important to be aware of the associated costs and factors that can influence the final price. The total ac coil replacement cost can be broken down into two main components: the air conditioner coil price itself and the labor required for the replacement.
HVAC Labor Cost
HVAC contractors typically charge between $75 to $150 per hour for repair and replacement work. For an AC unit evaporator coil replacement, the labor can take anywhere from two to four hours, resulting in a labor cost of approximately $150 to $600.
Evaporator Coil Style
There are three main styles of AC unit evaporator coil available, each with its own price range:
- A-coils: These triangular-shaped coils are the most common style and are designed to work with vertical airflow. The average cost for A-coils is around $1,300.
- N- or Z-coils: Shaped like an N or a Z, these coils can handle both vertical and horizontal airflow and have an average cost of $1,500.
Slab units
Also known as horizontal units, these coils are exclusive to AC systems with horizontal airflow. They have the lowest average cost at approximately $1,200 but are less commonly used.
It's worth noting that uncased coils are available at lower prices, but they are more difficult to install and may be more prone to damage. HVAC experts usually recommend cased coils for better performance and longevity.
By Brand
For optimal fit and efficiency, it's advisable to purchase a replacement HVAC evaporator coil from the same brand that manufactured your air conditioning unit. While generic replacement parts may save you money (costing as low as $150 to $300 for a new coil), using non-branded components may pose a risk of long-term damage to your system.
Other Services Provided
Replacing a faulty air conditioning evaporator coil promptly is essential to avoid potential strain on other components, such as the compressor. Replacing an AC compressor can cost around $1,800, significantly impacting the overall repair expenses. If other expensive components are in need of replacement, it might be more cost-effective to consider installing a new air conditioning system.
Total AC Replacement
In certain cases where multiple components are malfunctioning or the system is old and inefficient, it may be more practical to replace the entire air conditioner rather than just the coil. The cost of a new central air installation can vary, but it typically amounts to around $5,700.
Permits
When installing a new HVAC system, acquiring a permit is usually required. However, for smaller projects like evaporator coil replacement, a permit might not be necessary. Your HVAC technician can advise you on whether a permit is required, and if so, the cost of AC coil replacement is generally minimal, ranging between $50 and $200.
Warranty
If your HVAC system is still under warranty, you may not have to bear the air conditioner coil price, only the labor charges. Even if your warranty has expired, check your home warranty plan (if you have one) to see if it covers your HVAC system.

AC Evaporator Coil Replacement Cost by Unit Size
When it comes to air conditioning units, the size of the AC system plays a significant role in determining the AC unit evaporator coil replacement cost. AC units are measured in tons, with each ton representing 12,000 BTUs, a unit of heat. As a general rule, larger AC units tend to have larger and more expensive air conditioner coils compared to smaller ones.
If you reside in a spacious home equipped with a powerful central AC system, you can expect to spend more on replacing the home AC evaporator coil than if you lived in a smaller living space with a less powerful unit.
Below is a table showcasing the average HVAC coil replacement cost based on the size of the AC unit:
| AC Size | Average Evaporator Coil Cost |
| Run Capacitor | $9 - $32 |
| Dual-run Capacitor | $18 - $45 |
| Start Capacitor | $8 - $28 |
| Heat Pump Capacitor | $15 - $25 |
| Blower Capacitor | $9 - $15 |
As seen in the table, the HVAC coil replacement cost in AC varies depending on the type of capacitor needed for replacement. Whether you require a run capacitor, dual-run capacitor, start capacitor, heat pump capacitor, or blower capacitor, the prices will differ within the mentioned ranges.
