How to Replace an AC Compressor?

AC compressor replacement  Tucson, az is a complex errand that requires cautious arranging, information on HVAC frameworks, and the right apparatuses and gear. It’s fundamental to take security safety measures and producer rules into account to guarantee the substitution is done accurately. Here’s a step-by-step guide on how to replace an AC compressor:

Turn off the Power:

Before beginning any work, turn off the control to the AC framework at the circuit breaker or disengage the switch. This will anticipate the chance of an electrical shock while working on the compressor.

Release Refrigerant:

If the AC framework still contains refrigerant, it must be appropriately cleared some time after recently replacing the compressor. This ought to be done by a certified HVAC professional utilizing specialized hardware to capture and reuse the refrigerant in accordance with natural regulations.

Disconnect Electrical Connections:

Disconnect the electrical connections to the compressor, counting the wires associated with the terminal box or capacitor. Name each wire or take a photo to guarantee appropriate reconnection later.

Remove Get to Panels:

Remove the get-to boards covering the compressor unit. This may require evacuating screws or jolts to secure the boards in place. Set the boards aside in a secure location.

Disconnect Refrigerator Lines:

Carefully detach the refrigerant lines from the compressor using a torque or attachment set. Be arranged for any leftover refrigerant to elude as the lines are disconnected.

Remove Compressor:

Using fitting apparatuses, such as torques or attachments, evacuate the mounting jolts or brackets securing the compressor to the base or outline of the AC unit. Lift the compressor out of the unit and set it aside.

Before introducing the unused compressor, guarantee it is consistent with your AC framework and matches the details of the ancient compressor. Exchange any essential components, such as mounting brackets or electrical associations, from the ancient compressor to the modern one.

Install the Unused Compressor:

Carefully put the unused compressor into position in the AC unit, adjusting it with the mounting gaps or brackets. Secure the compressor in place by utilizing the mounting jolts or brackets.

Reconnect Refrigerator Lines:

Reconnect the refrigerant lines to the unused compressor, utilizing unused O-rings and fixing them safely with a torque or attachment set. Take care not to overtighten the associations, as this can harm the fittings.

Reconnect Electrical Connections:

Reconnect the electrical wires to the modern compressor, coordinating each wire to its comparing terminal. Guarantee all associations are secure and tight to anticipate electrical issues.

Replace Get to Panels:

Replace the get-to boards covering the compressor unit, securing them in place with screws or jolts. Guarantee the boards are appropriately adjusted and situated to anticipate and discuss leaks.

Vacuum and Charge System:

Once the modern compressor is introduced, the AC framework must be vacuumed to eliminate any dust and dampness. After vacuuming, the framework ought to be energized with the appropriate amount of refrigerant according to producer specifications.

Test System:

After completing the substitution, turn the control back on to the AC framework and test it to guarantee the compressor is working appropriately. Screen the framework for any abnormal clamors, vibrations, or execution issues.

Professional Inspection:

It’s fitting to have a proficient HVAC specialist assess the AC framework after compressor substitution to confirm legitimate establishment and execution. They can also perform any fundamental alterations or fine-tuning to optimize framework operation.


Remember, replacing an AC compressor is a complex assignment that ought to be endeavored by experienced people with knowledge of HVAC frameworks. If you’re not comfortable performing the substitution yourself, it’s best to contract a certified HVAC professional to guarantee the work is done securely and accurately.
