Product Picture
The compressor is the power unit of the air-conditioning system
that puts the refrigerant under high pressure before it pumps it
into the condenser, where it changes from a gas to a liquid. A
fully functioning compressor is necessary for the air-conditioning
system to provide peak performance. On most cars, A/C compressors
are driven by an engine-accessory belt. If the belt is worn and
slips, the compressor won’t operate at full strength. Compressors
can also leak refrigerant, resulting in less cold air going into
the interior. Internal parts can also fail, leading to no cold air.
Not all air-conditioning problems are because the system is low on
refrigerant. Some are caused by issues with system parts, such as
the compressor.
Emergency situations
Some emergency indicators that something is wrong with your
compressor include:
- Weird noises: This could be caused by a worn or broken belt/pulley.
There are several other issues that may need to be addressed
immediately.
- Burning smell: The compressor wiring may be damaged or burned.
- Leaking dashboard: It could be caused by a clogged hose or drain.
Age and moisture can also cause your system to leak.
If you notice any of these issues, it's important to fix the
problem as soon as possible.
General system
Each system may vary slightly per vehicle. For example, some may
include an orifice tube whereas others have an expansion valve.
This means the system has up to 7 components including:
- Compressor: compresses cool refrigerant gas into hot refrigerant
gas
- Condenser and fan: converts hot refrigerant gas into a hot liquid at high
pressur
- Receiver Dryer: temporarily stores refrigerant when not needed by
the system
- Expansion (TX) Valve / Orifice Tube: regulates refrigerant flow /
creates pressure drop
- Evaporator: cools air before entering cabin
- Heater Core: warms air before entering cabin (uses engine coolant rather than refrigerant)
- Blower Motor: fans hot or cold air into the cabin
warning sign
- The Compressor Isn't Activating: If your car's AC system is not
producing cold air when it is turned on, the compressor may be the
issue. To check if power is reaching the compressor, use a
multi-meter. If no power is reaching the compressor, it is
recommended to take your car to a mechanic or an auto electrician
for further diagnosis and repair.
- Warm Air Instead of Cold Air: Another common indication of a
failing AC compressor is when the air conditioner starts blowing
warm air instead of cold air. This could be due to a refrigerant
leak or insufficient refrigerant gas levels. In some cases,
replacing the entire AC system may be necessary to resolve this
problem.
- Loud Noises Emanating from the Compressor: A failing AC compressor
may produce loud noises, a clear sign of its deteriorating
condition. These noises could be a result of a faulty clutch or
worn-out bearings. They are often described as grinding sounds
coming from under the hood when the AC system is activated.
- Oil Leak Under the Vehicle: An AC compressor in poor condition can
lead to oil leaks. This occurs due to excessive heat and pressure
within the engine bay, leading to worn-out compressor seals over
time. If you notice any liquid leaking underneath your car, it is
essential to have it inspected promptly to prevent further damage.
