The compressor basically has two tasks. One is to make sure that the refrigerant flows into the system. Another is that it pressurizes the system. It turns on and off in a continuous manner in order to keep the cabin cool. Due to this manner of functioning, it is inevitable for the unit to wear and tear. Here are signs to take note of to know when it is time to replace the unit, particularly that of your Volvo A/C compressor.
Moisture Leaking Around the Unit
When leaks are present on an air conditioning unit, there is reason to be alarmed. There are times when this can be caused by clogged or simply dirty coils. But there are instances that a failing compressor can also result in a leaking refrigerant. Take note that the refrigerant contains Freon, a substance that not anyone should come into contact with as it can result in severe headache, irritated eyes, cough, nausea, and a whole lot more.
The potential risks that come with leaking refrigerants should be enough reason for you to call an A/C repair technician for help. When the leak is ignored then the compressor can possibly run out of refrigerant. This can dry up the compressor which will later on stop it from working. This will dictate replacement which can be very costly but it will be best to do so right when you spot any problem that hinders it from working.
Unusual Noise from the AC System
Turning on the car's A/C system will bring much comfort to you. Imagine how cold air flows into the cabin and how it refreshes you thereafter. What if you suddenly hear a noise coming from the A/C system after switching it on? You need to take a second look to find out what can be causing the problem. Commonly, this is caused by a bad compressor, where it struggles to do its job and work as usual.
The strange noise produced by the AC system can be caused by loose bearings. This creates a grinding noise that is so irritating to the ear. A leaking bearing can also be indicated by a squealing noise. Any type of noise that you hear when you turn on the system must be a reason to send it off to an auto repair shop for inspection.
Air Flow Changes
Air flow output is one of the reasons why compressors are parts of an AC unit. When the quality of air coming out of the vents diminishes, then it can be taken as a sign that the compressor has started going bad. Once the air flow changes, you must call an A/C repair company to look into the problem and see what else can be done about it.
Changes in Temperature
Another change that is common with a bad compressor is change in temperature in the cabin. This happens when instead of cold air coming out from the system, warm air comes out of it instead. This happens because the compressor has failed to regulate the flow of the refrigerant in the system. With this, you need to replace the compressor right away.
