Cost To Replace An Air Conditioner Compressor

Facing a malfunctioning air conditioner can be stressful, especially when you learn that replacing the compressor—one of the most crucial and expensive components—might be necessary. In Portland, the cost for a new AC compressor typically ranges from $1,000 to $3,000, and sometimes even higher. Given these significant expenses, you might wonder whether it's wiser to replace the entire unit instead of just the compressor.

Why is a compressor replacement so costly? In this article, we’ll break down the factors that influence the price of a new compressor, including:

  • Type of compressor
  • Capacity and efficiency
  • Labor costs
  • Warranty and brand
  • Additional repairs and upgrades

If you’re concerned about your AC’s performance and suspect the compressor might be the issue, it's essential to consult with a qualified HVAC professional who can accurately diagnose the problem and guide you through your options. This way, you can make a financially sound decision based on expert advice.

Type of Compressor

Modern residential AC systems run on one of two basic types of compressors: reciprocating or scroll. In a reciprocating compressor, pistons move up and down to provide compression for the refrigerant, returning it to liquid form. A scroll compressor moves in an orbit around a stationary center, much like a scroll. Scroll compressors are generally more energy-efficient, quieter, and expensive.

The choice between a reciprocating or scroll compressor often depends on system compatibility. In many cases, you'll need to replace the existing compressor with the same type, so you won't be able to choose an affordable or more energy-efficient alternative. If your unit can use either type, your budget will likely drive the final decision. Scroll compressors can cost three times more than reciprocating compressors.

Capacity and Efficiency

Bigger is better when it comes to compressors. A larger compressor is more energy efficient and better able to produce cooling, but it's more costly to buy. However, the improved energy efficiency makes these units cheaper to run, which means a larger size may save you money in the long run. Discuss the options with your technician. Most units have a recommended size from the manufacturer that will determine the price. But in general, the greater the unit's cooling capacity, the more you should expect to pay for a compressor.

Labor Costs

Labor costs typically account for at least half of the cost of AC compressor replacement. The more complex the job, the more you should expect to pay in labor, though hourly rates can vary dramatically based on location and the contractor's expertise. At Four Seasons Heating & Air Conditioning, we strive to offer the best service, which means we work with NATE-certified technicians with lots of experience. You may pay more per hour, but we get the job done right the first time so you don't need to worry about costly repeat visits.

Additional factors that can impact labor costs include:

  • Compressor accessibility: Repairs will likely take longer if it's on the roof or a difficult-to-reach location.
  • System age and condition: If your system is older, we may need to install an after-market part or make other repairs in addition to replacing the compressor.

When comparing AC compressor replacement costs, it's important not to look only for the lowest price; instead, look for reliable service and a good reputation from the company doing the work.

Warranty and Brand

The warranty offered by the compressor manufacturer and the brand's reputation are also important considerations. A compressor with a longer warranty period may have a higher initial cost, but it provides better protection and peace of mind against potential future issues.

Similarly, reputable brands known for quality and reliability often command higher prices for their compressors. However, investing in a trusted brand can lead to fewer maintenance issues and longer-lasting performance.

Additional Repairs and Upgrades

During the compressor replacement process, HVAC technicians may identify additional repairs or upgrades necessary or beneficial for the system's performance and longevity. Leaking or damaged refrigerant lines are common causes of compressor failure, so these should be addressed at the same time. You may also want to have filters replaced to protect your new compressor, or we may recommend sealing your ducts to help reduce the load on your air conditioner.

While these additional repairs and upgrades add to the overall cost, they can deliver significant benefits in terms of comfort, efficiency, and system reliability.
