Evaporator Coil Replacement Cost Range
Replacing an HVAC system’s evaporator coil can cost anywhere from $910 to $2,460, with most homeowners spending an average of around $1,340.
Listed below, is what most HVAC companies include in the total cost when they replace your HVAC system evaporator coil.
Diagnosing Current System: Inspection of the HVAC system to identify the need for an evaporator coil replacement and to determine the correct size and type of coil needed.
Removal of Coil: Safely dismantling and removing the existing evaporator coil from the HVAC unit.
Replacement Parts and Supplies: Choosing the evaporator coil that matches the HVAC system’s specifications, including size, capacity, efficiency and type.
Installation of New Coil: Carefully installing the new evaporator coil into the HVAC unit, ensuring it is correctly positioned and secured.
Handing of Refrigerant: This may include evacuating the existing refrigerant from the system, recharging the system with the correct type and amount of refrigerant, and ensuring there are no leaks.
Completing Installation: Reconnecting all necessary electrical connections, ductwork, and other components that were disconnected during the replacement process.
Testing: Running the system to check for proper operation. This includes testing the airflow, temperature output, and ensuring the system cycles on and off correctly.
Cleanup and Disposal: Properly disposing of the old evaporator coil and any other replaced parts according to local regulations, and cleaning up the work area.
Warranty and Documentation: Providing warranty information for the new evaporator coil and possibly updating the HVAC system’s service records.
Evaporator Coil Cost Factors
HVAC Unit Size: The size of the evaporator coil needs to match the HVAC unit’s capacity, which is measured in tons or BTU. Larger HVAC units require bigger evaporator coils, which can be more expensive.
Warranty Coverage: If your unit is still covered under a manufacturers warranty and you’ve kept annual maintenance records, the factory will usually cover the parts cost, leaving you with only the labor cost.
Replacement Labor: Labor costs typically make up about 40% of the total replacement cost. The complexity of the replacement and the time it takes to complete the installation can influence this factor.
Refrigerant Type: The type of refrigerant the system uses can affect the price, especially if it requires a specific type or more expensive refrigerant.
Type of HVAC Unit: The model and type of your HVAC system can impact the cost. Certain systems might need specialized coils like slab coils, N-coils, A-coils etc, that may be more costly than standard ones.
SEER Rating: The Seasonal Energy Efficiency Ratio (SEER) rating of your system can play a role in the cost. Higher SEER ratings may require more advanced, and thus more costly, coils with TXV systems.
Coil Type and Brand: Different brands and styles of coils vary in price. Premium brands often charge more for their parts, including evaporator coils.
