How Much Does It Cost to Replace Your AC Coils?

According to national averages, the typical AC coil replacement cost is between $1,200 and $2,500 for evaporator coils and $1,500 and $3,000 for condenser coils. These large ranges account for factors such as how convenient a system’s coils are to access, differences in parts costs across different HVAC brands, and regional labor rates.

Average Cost to Replace Evaporator Coils
Replacing the evaporator coils, which are located indoors in the furnace or air handler, is often less expensive than replacing the condenser coils. However, while the parts themselves are less costly, they can be challenging to access, driving up labor costs. On average, parts and labor rates range between $1,200 and $2,500.
Your HVAC system may be under a warranty if it is relatively new. This could significantly cut down on what you have to pay for the repair or even take care of the cost of the repair altogether. If your system isn’t under warranty, you may have financing options. At Comfort Systems, we make it easy for you to get the repairs you need on your schedule through our convenient financing plans.
Factors That Affect Evaporator Coil Replacement Cost
The wide AC evaporator coil replacement cost range reflects a variety of factors. These include:
- AC unit size and energy efficiency rating. Units that are larger or have a higher SEER2 rating generally use more expensive coils.
- What the coil is made from. The coil material affects the cost of the part, with aluminum coils costing less than copper coils.
- The complexity of the job. If the furnace or air handler is hard to access, labor costs will be higher.
- The type of refrigerator needed. If your system is older and uses a refrigerant that’s in limited supply, such as R-22, the total cost of the repair will increase.
Average Cost to Replace Condenser Coils
Condenser coils, which are located on the outdoor part of your air conditioning system, tend to cost more to replace. They’re often larger, and they have to be constructed of more durable materials because they’re exposed to a wide range of weather conditions.
According to national data, households typically spend between $1,500 and $3,000 to replace condenser coils. While the AC condenser coil cost is a significant investment, it’s often more cost-effective than replacing the entire outdoor unit.
Factors That Affect Condenser Coil Replacement Cost
When determining the cost of replacing the condenser coils, we consider several factors:
- The brand of the AC unit. Some AC units use coils that are compatible across multiple brands and systems, while others use proprietary parts that are more expensive.
- The AC unit’s size. The larger the AC unit is, the larger the condenser coil is and the more it costs to replace.
- Ease of access. If the outdoor unit is in a place that’s hard to access, such as on a roof, labor costs run higher compared to units that are at ground level.
- Typical labor rates. Labor rates, which can vary by location and season, impact the total cost of the replacement.
Signs Your Coils Need Replacement and How to Decide Between Repair or Replacement
Replacing your coils is a significant investment; in some cases, spending that money toward upgrading the entire system may make more sense. If you notice warm air coming from your vents, ice buildup, refrigerant leaks, or unusual noises coming from the air conditioner, a full replacement may make more sense. This is especially true if the unit is older than 10 years.
Minor issues can be fixed, but severe corrosion or leaks often require replacement. At Comfort Systems, we bring honesty and respect to every job to help you decide the best option.
