## Home AC Compressor Cost

A home AC compressor costs $600 to$1,200 to replace when under warranty or $1,300 to$2,500 when out of warranty. AC compressor prices are $400 to$1,300 for the unit alone, depending on the size, type, and brand. The labor cost to replace a compressor is $600 to$1,200.

AC Compressor Cost
Replacement Type Total Cost
Compressor Still Under Warranty $600 –$1,200
Compressor Not Under Warranty $1,300 –$2,500

Replacing the whole AC unit or heat pump is sometimes more cost-effective than replacing a compressor out of warranty. Installing a new AC unit costs $2,500 to$7,500, while a new heat pump costs $3,800 to$8,200.

• AC compressors cannot be repaired on-site and require replacing instead.

• Replacing an AC compressor takes 4 to 6 hours.

• AC compressors last 10 to 20 years.

• Many heat pumps use the same type of compressor.

## Average Cost To Replace AC Compressor

The following table shows the average cost to replace an AC compressor that is not under warranty.

### Should I Replace My Compressor or Whole AC Unit?

Because compressor replacement is so expensive, it's sometimes more cost-effective to replace the whole AC unit instead. However, if the unit is still under warranty, most HVAC technicians recommend replacing the compressor.

Consider replacing the whole AC unit if:

• The compressor is no longer under warranty.

• The AC unit is more than 10 years old.

• The unit has a history of other problems.

• The repair cost is 50% or more of the price of a new AC unit.

Before replacing the compressor or entire AC system, have a technician inspect the unit for other problems. Compressor failure symptoms often mimic the symptoms of other issues that cost less to repair.

### How Long Does It Take To Replace An AC Compressor?

Replacing an AC compressor takes 4 to 6 hours on average. The refrigerant must be drained before the compressor is removed and then refilled after installing a new compressor. Jobs may take longer than one day if the technician does not have the correct parts in stock.

## Hiring An AC Compressor Installer

A licensed technician should handle AC compressor replacement. Before hiring an HVAC professional, be sure to:

• Get at least three estimates to compare. Let pros know you’re getting bids from multiple contractors to get the best competitive price.

• Look for a NATE-certified technician with experience installing and repairing air conditioners.

• Confirm the technician is EPA Section 608 certified to handle refrigerants.

• Select companies that are insured, bonded, and have been in business for 5+ years.

• Avoid selecting the lowest quote as quality may suffer.

• Ask for a written contract and warranty.

• Get a full breakdown of all costs involved.

• Avoid making large payments upfront. Come up with a payment schedule for the work completed.

• How many air conditioner compressors have you replaced?

• Are you EPA Section 608 certified to handle refrigerants?

• Are you licensed, insured, and bonded?

• Are these new parts, and do they meet the air conditioner manufacturer’s specifications for quality replacement parts?

• Does the new part come with a warranty?

• How do you handle damages that happen on the job?

• What permits do I need, and will you obtain them?

• Do you guarantee your work? What does your warranty policy include?

• What is your payment schedule?
