Replace Air Conditioner Compressor or AC Unit? A Cost Guide.

old unit in need of HVAC system upgrade

When an AC condenser unit stops working, the air compressor may be the cause of the malfunction. It’s time to decide whether you should replace your air conditioner compressor or buy a new AC unit?

Signs of wear and tear could mean it’s time to purchase a new air conditioner. In some instances, maintenance and repair may provide more value and increase the lifespan of the air compressor and other parts.

Replacement costs vary based on product warranties and the age and condition of the unit. Continue on to explore the cost to replace an air conditioner compressor, the significance of Seasonal Energy Efficiency Ratio (SEER) ratings, and the value of hiring a qualified HVAC professional for regular seasonal maintenance.

Cost to Replace Air Conditioner Compressor

The average cost to replace an air conditioner compressor in 2023 is around $1,200 nationally.

Prepare as many details as possible to present to an HVAC professional when scheduling service for repair. This information may help you save money on AC air compressor replacement costs.

  • Identify the brand and model of your HVAC or AC unit. It may be compatible with multiple AC compressor brands. A generic option may be available at a lower cost.
  • Note the age and condition of the cooling unit and determine if warranty protection covers it. Some warranties may cover the cost to replace an air compressor.

Contact an HVAC specialist with this information in hand. They can help you select the best part for replacement.

Factors Affecting Air Conditioner Compressor Replacement Costs

HVAC equipment parts can be expensive. When an air compressor fails, it may be difficult to replace the faulty part. Specialized tools and equipment may be necessary to complete the repair.

The average cost of an AC compressor, including parts and installation, can vary based on several factors.

  • HVAC System Type: The type of air conditioning system can affect the cost of replacing an air conditioner compressor. For instance, replacing the part in a central air conditioner can be more expensive than a window air conditioner unit.
  • Air Conditioner Brand and Model: The AC brand and model can affect cost. Not all air conditioner parts are compatible with other product lines. Choose a brand that works with your current air conditioner.
  • Property Location and Labor Rates: HVAC repair and installation fees vary by location. Parts and labor costs may be higher in some areas than others.
  • Additional Components: Installation may require replacing other parts, including mounting brackets, new refrigerant lines, or coils.


An HVAC specialist can help with all of this.

According to Angi, the range for parts and labor on an AC compressor is between $800 and $2,800 for a central air conditioning unit. In some cases, it may make more sense to do a total condenser unit replacement.

Warranty Coverage

Home and manufacturer warranties can often offset the expense of replacing an air conditioner compressor. If failed components cause electrical tripping issues, a manufacturer warranty may cover a condensing unit replacement.

Some warranties may require an expert HVAC service provider. Check your warranty status and contact your coverage provider before moving forward with any repairs.

Cost to Replace an AC Unit

When deciding whether to repair or replace AC, consider the age of the broken AC unit. Frequent repair issues, poor airflow, and shifting temperature changes can indicate that you need to replace an AC unit.

The $5,000 rule involves multiplying the age of the broken AC unit by its estimated repair cost. If the result exceeds $5,000, consider replacing your AC unit.

The Value of Professional Installation

Hire a qualified technician for the job. Professional installation can reduce the risk of issues related to incorrect setup or faulty components. An experienced HVAC specialist will inspect your existing unit and install a new AC unit or compatible air conditioner compressor part for replacement.

SEER-Rated Savings

Make an informed AC unit decision by researching SEER ratings. If your current AC unit has a low SEER score, replacing the compressor may not be enough to get the desired outcome. Consider purchasing a new AC unit with a high SEER rating.

The Guide to Home Heating and Cooling recommends a SEER rating of at least 14 for air conditioning systems. An 18 SEER rating uses 20% less energy than a 14 SEER system.

The U.S. Department of Energy has set efficiency requirements for households using central air conditioners or heat pumps. Based on the DOE calculations, homeowners can collectively save $2.5 billion to $12.2 billion on energy bills between 2023 and 2052.

Higher rated air conditioners can be worth the investment. Upgrade to a model with a high SEER rating to save money and use less energy as you cool your home.

Regular Maintenance Checks

Increase the lifespan of your unit through regular maintenance. Identify potential repairs before they become big problems.

Schedule routine maintenance with a certified technician to save on the cost of parts and equipment repair.

Regular HVAC maintenance with coil cleaning, filter changes, and central air fan motor lubrication can help prevent system failure or damage. A qualified HVAC technician will inspect your AC system and may also consider replacing other aging parts.

Benefits of HVAC Maintenance

Heating and cooling systems may break down during periods of high energy use. Aging parts can also lead to expensive repairs. Preventive maintenance is the key to avoiding an unexpected breakdown at a later date.

HVAC preventive maintenance can help a heating and cooling system operate more efficiently. Professional HVAC service can improve energy use, extend the lifespan of equipment, and help you save money in the long run.

Factors determining how often to schedule HVAC maintenance may vary depending on the size of an HVAC unit. Contact an experienced HVAC technician for a detailed cost estimate.

Hire an HVAC Professional to Replace an Air Conditioner Compressor or AC Unit

A broken compressor will cause an HVAC system to fail. If your air conditioner compressor is broken, consider a replacement. In many cases, replacing the air compressor can be more cost-effective than purchasing a new AC unit or constantly calling for repairs.
