Is your air conditioner struggling to keep your home cool? If so, a faulty evaporator coil might be to blame. The evaporator coil is responsible for absorbing heat from your indoor air and helping your AC function properly.
When it goes bad, your cooling system won’t work efficiently, leading to higher energy bills and poor comfort. But how much does it cost to replace an evaporator coil? Let’s break it down.
Average Cost of Replacing an AC Coil
The cost of replacing an evaporator coil typically ranges between $627 and $2,700, with most homeowners paying around $1,350 on average. This price includes the cost of the coil, labor, and refrigerant. However, if your AC is still under warranty, you may only have to pay for the labor and additional materials.
What Factors Affect the Cost?
Several factors influence the final cost of replacing an evaporator coil:
- Type of Coil – A-coils, N- or Z-coils, and slab coils all have different price points. A-coils, the most common type, cost around $1,300, while N- or Z-coils cost $1,550, and slab coils are the most affordable at $1,200.
- Size of the Unit – The larger your AC unit, the more expensive the replacement will be. For example, a 2-ton coil replacement might cost between $550 and $2,000, while a 5-ton coil replacement could range from $900 to $2,700.
- Labor Costs – HVAC technicians typically charge between $75 and $150 per hour. If your coil is difficult to access, expect higher labor fees.
- Location – Prices vary based on where you live. Urban areas tend to have higher labor costs compared to rural regions.
- System Age – If your AC system is older, replacing the coil might not be enough—you may need to replace other components as well.
When to Replace vs. Repair Your Evaporator Coil
Not sure if you should repair or replace your coil? Here are some signs to consider:
- Repair if: Your system is under 10 years old, the damage is minor, and repairs cost less than 30% of a full replacement.
- Replace if: The coil is significantly corroded, leaking refrigerant, or your system is outdated (10-15 years old). If your AC uses R-22 refrigerant, which is being phased out, replacing the coil may not be cost-effective.
Final Thoughts
Replacing an evaporator coil is a significant investment, but it’s essential for keeping your home cool and comfortable. If your AC isn’t performing well, it might be time to inspect the evaporator coil and consider replacement.
