summer approaches, people are doubly motivated to make sure their car's air conditioning system is working properly. In some cases, they may have noticed problems months ago and postponed repairs due to budget constraints or inconvenience. With the warm months around the corner, however, fixing the A/C is understandably given a higher priority.
One of the most common complaints people have regarding their air conditioner involves a lack of cold air coming from the vents. Below, we'll approach the issue step by step. First [link widoczny dla zalogowanych], I'll describe the difference between a lack of cool air and low air volume (many people confuse the two issues when describing the details to their mechanics). Then, we'll take a look at whether a lack of refrigerant is the culprit [link widoczny dla zalogowanych], or if other factors are to blame.
Lack Of Cold Air Versus Lack Of Volume
A lack of cold air coming from your car's vents is caused by different circumstances than a lack of air volume. For this reason, it is important to not only discern which problem you're experiencing, but to describe it accurately to your mechanic. Otherwise, he may waste time trying to troubleshoot an issue that doesn't exist.
If the air from your vents feels warmer than it should, the reason may be due to an obstruction within the system or a failing component (e.g. the compressor). The job of your compressor, for example, is to pump refrigerant through your car's air conditioning system. If it fails [link widoczny dla zalogowanych], the A/C will be unable to cool the air.
Many people instinctively assume the issue occurs because of a lack of refrigerant. In reality, while refrigerant can leak (the A/C does not consume or "use it up"), other factors are just as likely to be the cause.
As a side note, if you're experiencing a low volume of air coming out of your vents, the problem is likely a failing blower motor or a blockage in the system.
Should You Recharge The A/C System?
As noted earlier, your vehicle's air conditioner does not consume refrigerant. Nor does it simply "lose it" in the same way your tires lose air pressure over time. If the level is low, a leak exists somewhere in the system. Recharging the A/C will not solve the underlying issue; the leak will continue until your air conditioner is unable to blow cold air (again).
Finding an A/C leak is difficult unless you have access to the appropriate equipment. This is a compelling reason to let your mechanic handle the job. He'll introduce a special dye into the air conditioner's path, and follow it with his diagnostic tools. As the dye moves from the compressor to the condenser, and then to the receiver dryer to the expansion valve, leaks show up on your mechanic's equipment.
If you would like to do this on your own, you can purchase a freon leak detector online for under $150. Most people, however, will be better served taking their car to a trained technician.
Other Reasons Automotive Air Conditioners Fail
Aside from compressor failures and refrigerant leaks (typically, from deteriorating hoses and O-rings), your car's A/C may fail for other reasons. For example, dirt can enter the air conditioning system, causing the compressor and expansion valve to malfunction. Dirt may also cause the refrigerant to break down over time.
Another common problem is the accumulation of moisture on the evaporator. It comes from the air and condenses on the component's surface. It can contribute to the formation of corrosive acids that eventually cause the A/C to fail. The receiver-drier and accumulator are tasked with removing moisture from the system, but may fail to do so if too much collects.
Your air conditioner may also malfunction if the drive belt that connects the compressor to the engine breaks or becomes loose. This can happen from prolonged exposure to heat and normal wear.
If your A/C is blowing warmer-than-normal air, have your mechanic find and fix the problem. With the summer months approaching, the investme
