Home AC Compressor Cost Factors

The cost of a replacement compressor for your home AC system is going to depend on a few factors. Most important, is whether or not the compressor is still covered under the manufacturer warranty, since the parts cost and labor are really are you’ll be paying for.

Type of Compressor

There are various types of HVAC compressors installed in residential systems. Reciprocating, scroll, screw, and rotary are the most common, with some being more efficient and thus more expensive.

Compressor Size or Capacity

The cost varies with the compressor’s size, often measured in tons or BTUs, as larger compressors have higher capacities and costs.

System Brand and Quality

Higher end brands like Trane, Carrier, American Standard or Lennox are known for long term durability and efficiency, and when OEM parts are used they may have higher prices, impacting the overall compressor replacement cost.

Refrigerant Type

The type of refrigerant (e.g., R-22 vs. R-410A) can affect the cost, especially if a refrigerant retrofit is required.

Local Labor Costs

Labor costs vary by city, state and region, installation complexity, and if the system needs modifications to bring it up to code. This may impact total costs.

Unit Accessibility

Hard-to-reach units like those on a roof or in a crawl space, attic etc, may lead to higher labor costs due to additional time and effort required by the HVAC technician.

System Warranty

If your system is still covered by the manufacturers warranty, they may cover the cost of the compressor and parts. They will not generally cover the labor expense and you’ll pay labor costs.

Season and Demand

Costs are generally higher during peak cooling season due to increased demand for HVAC technicians. While you may not have the luxury of waiting until the off-season to replace your compressor, it could save you money on labor and installation costs.

Additional Parts and Repairs

It’s common and may be required that you replace additional parts, such as capacitors, refrigerant or filter driers. These parts may add to your overall cost.

Urgency of Replacement

Replacement or services that are provided after normal hours or on weekends can incur higher costs due to the expedited nature of the service.

Central Air Conditioner

A central HVAC system that cools the entire house with the use of an air handler or furnace and uses a network of ducts to distribute cooled air.

Heat Pump

Similar to a Central AC Unit, a Heat Pump system provides both heating and cooling for a home, transferring heat between the indoors and outdoors and commonly distributed via an HVAC duct system.

Ductless Mini-Split

Provides heating and cooling without the need for ductwork and is suitable for room additions or homes without existing ducts. New ductless mini split systems are able to be installed much easier by a do-it-yourself homeowner.

Window Air Conditioner

A compact unit installed in a window to cool a single room or area. Commonly available in sizes from 2,500 btu up to 18,000 btu which are designed to cool up to 1,000 square feet.

Portable Air Conditioner

A mobile unit that can be easily moved from room to room, venting through a window or a vent port built in to the side of a structure.

Packaged Terminal (PTAC)

Often found in commercial settings, hotels or apartments, these units are installed through a wall and serve individual rooms.

Compressor Replacement Costs by Brand

The brand name on the side of your central air conditioner has an effect on the cost of replacing your compressor. While most manufacturers use similar parts, not all are the same. Higher quality brand simple cost a bit more.

Permits, Inspection, Installation Labor Costs and Time

Not all states require permits and/or inspections for repair of HVAC units like this. If they are required, your HVAC contractor will let you know and schedule according to your availability.

  • $0  | Mechanical and Other Inspections
    Since this is a part repair, versus complete system change-out, you are not likely to need a permit or inspection for replacing your home compressor.

Home AC Compressor Installation Labor Cost and Time

Even when a compressor is covered through your manufacturer warranty, its rare for them to cover the labor cost of an HVAC technician labor and/or diagnostic fees, unless it occurs within the first year of ownership. You can expect to pay an average of $830 in labor costs, or somewhere between $420 – $1,400 in labor cost to replace the ac compressor at your house.

  • $830 | Average Labor Cost for an HVAC company to replace your air conditioner compressor.
  • $59 – $129 | Service and diagnostic fee to determine compressor was bad. (May be credited back to you after repair)
  • $60 – $90 per-hour | Service Technician Labor Fee
  • $60 – $75 per-hour | Service Helper Labor Fee

Completed Installation Time

In most cases, an HVAC repair technician can determine that a compressor is faulty within the first hour of a service call. While some might carry an assortment of 3-5 replacement compressors on their parts truck, many will need to go to a parts supply house to get a specific replacement for your home ac unit. If the compressor is covered by warranty, the part must come from an approved manufacturer supply house.

  • 2-4 hours | Diagnose, repair with part already on service truck.
  • 4-6 hours | Diagnose and have replacement compressor delivered from the repair company parts runner.
  • 6 hours or more | In cases where it takes the service technician longer than 6 hours of labor to complete your repair. It’s likely that they had to run to the parts house themselves, removed and replaced broken compressor, etc.

DIY or Hire a Pro

In 90% of cases, this is a repair job you’ll have to hire an HVAC professional to do for you. If the unit is under warranty, a licensed HVAC service company may be required to perform the repair for you in order to handle the warranty paperwork and return the parts. While a DIY’er might be able to handle some of this job, there is simply too many tools and procedures that a handy homeowner is not going to be be prepared for.

  • Requires refrigerant certification. (And refrigerant)
  • Requires trade-specific tools and skills. (vacuum pump, high temp torch, brazing, etc)
  • Must be able to process warranty claims when applicable.

I consider myself an 8/10 on the handyman scale, and I would hire a pro to do this job every time.
