What a Service Kit Typically Includes

Kit contents depend on the compressor and the maker. For example, Emerson describes its Copeland service compressor kits as including parts such as the items below, packed with certain single-phase residential compressors.

Included part

Notes

Capacitors

Run capacitor, and on some models a start capacitor and relay

Filter drier

Captures moisture and contaminants in the refrigerant circuit

Contactor

Switches power to the compressor

Molded plug and mounting parts

Electrical connection and mounting hardware

Copper tubing and Comfort Alert module

Included on certain models only

Always check the listing to see exactly what a kit contains.

After a Compressor Burnout

If the old compressor failed because the motor burned out, installing the new one is only part of the job. These steps follow a trade article on replacement after burnout, and your equipment maker instructions take priority.

Step

What to do

Test

Use an acid test kit, check winding resistance for an open circuit and note any burnt smell

Recover and remove

Evacuate the system with approved recovery equipment, take the electrical system offline and remove the old compressor

Remove driers and valves

Pull filter drier cores, check valves and reversing valves, or bypass them before flushing

Flush

Flush with solvent in short bursts, then blow out residue with nitrogen

Install new driers

A suction line drier protects the compressor, and a liquid line drier protects the metering device and other components

Oil, vacuum and charge

Evacuate to about 500 microns, check for leaks, then charge refrigerant and oil to the manufacturer specification

The same article notes that a new compressor failing within about three months is most often caused by an incomplete flush.

How to Choose a Compressor Kit

Check

What to compare

Refrigerant

The refrigerant on the old nameplate, such as R-134A, R404A or R407C in these listings

Capacity

BTU rating or horsepower of the original compressor

Voltage and phase

115V, 208/230V single-phase or 460V three-phase

Oil

The oil specified for the compressor and refrigerant. Several Copeland items here are polyol ester (POE) oil.

Connections

Tube sizes, flare or sweat service valves and adapters

Model number

The compressor model on the nameplate, so a kit or component set fits that exact model

Frequently Asked Questions

A complete compressor kit typically comprises all essential components required for a comprehensive air conditioning (AC) system repair or installation. While specific contents may vary based on the application, a standard kit often includes:

  • Compressor: The primary component responsible for pressurizing and circulating the refrigerant.
  • Filter drier: Captures moisture and contaminants in the refrigerant circuit.
  • Electrical parts: Capacitors, a contactor and, on some models, a start capacitor and relay.
  • Mounting and connection parts: Molded plug, mounting hardware and sometimes copper tubing.
  • Compressor Oil: Lubricates the compressor and other moving parts within the system.

Contents differ by compressor and maker, so read the listing.

Signs indicating a failing or malfunctioning AC compressor include:

  • Insufficient Cooling: The AC system is unable to maintain desired temperatures.
  • Unusual Noises: Grinding, squealing, or rattling sounds emanating from the compressor unit.
  • Compressor Clutch Issues: The clutch fails to engage or disengage properly, affecting compressor operation.
  • Refrigerant Leaks: Visible signs of refrigerant leakage around the compressor or associated fittings.

Before you replace the compressor, rule out cheaper causes such as a failed capacitor or contactor, and check winding resistance. A technician can confirm whether the compressor itself has failed.

Installing a complete compressor kit involves handling refrigerants, precise calibration, and adherence to safety protocols. Due to the technical nature of the task and regulatory requirements concerning refrigerant handling, it is strongly recommended to hire a licensed HVAC professional to perform the installation. This ensures the system operates efficiently and safely.

Replace the filter drier, since the suction line drier protects the compressor and the liquid line drier protects the metering device. After a motor burnout the system must also be flushed, and the oil and refrigerant charge must match the maker specification. Skipping the flush is the most common cause of a new compressor failing early. See compressor parts & accessories.

The oil has to be compatible with the refrigerant, so use the one named on the compressor nameplate or in the maker data. One service guide pairs mineral oil with R-22 and polyol ester (POE) oil with refrigerants such as R-404A and R-410A, and Copeland POE oil is listed here. Check with the manufacturer before using a different oil.

Complete compressor kits are designed for specific makes and models of AC systems. It's essential to verify the compatibility of the kit with your particular system before purchase. Consulting with the supplier or a professional technician can provide clarity on the appropriate kit for your needs. Match the refrigerant, capacity, voltage and phase, and the compressor model number.
