What happens if you run a compressor with no oil?
At that point you’re running the compressor with little to no oil. You may get it to accept a charge, but you may have already damaged the compressor before the system reaches full charge. NEVER try to bypass the low pressure switch. Doing so will force the compressor to run with inadequate oil and can destroy the compressor.
How much does it cost to replace an AC compressor?
A new AC compressor with parts can cost anywhere from $400 to $2,550. To get the full compressor replacement cost, you have to add the labor costs of an HVAC technician that is paid anywhere between $50/h to $150/h. Labour represents 40% to 60% of the final AC compressor replacement cost.
Is there a warranty on an AC compressor?
Generally, you do get a warranty for parts; a warranty for an AC compressor is separate from the warranty for parts. You have 2-year, 5-year, 7-year, or even 10-year AC compressor warranties. However, the important part to note is this: AC compressor warranty includes only the compressor; not the labor.
How can I tell if my compressor is running or not?
Not really. DIY kits come with a low pressure side gauge and they’re designed to provide a static pressure (engine not running or AC off) and a running pressure. Static low side pressure won’t give you any idea of system charge. You could have a low side target range of 50-psi and see that static pressure on your gauge.

What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
What should I do if my compressor clutch is not working?
If you’re not getting battery voltage, pull the compressor clutch relay and check for power and ground on the relay control coil terminals in the socket. Wiring varies by make, model, and year. Some car makers trigger the relay control coil ground through the PCM or ECM.
