Perhaps you’ve found yourself in the following situation: You turn on your vehicle’s air conditioner, only to find that it’s blowing warm air, or no air at all. Not only is this frustrating, but it can be very uncomfortable. Problems with a vehicle’s air conditioning system can present themselves in a number of ways. Here are some of the questions we frequently receive:
Why is my car’s air conditioner blowing warm air?
This is likely happening because the air conditioning unit is low on refrigerant. When your system’s refrigerant is low, not only could it overheat, but it’s also not getting the lubrication it needs to function efficiently. Running a poorly functioning air condition system can cause serious damage, so be sure to leave it off until you can take your vehicle to a qualified Best-One® Tire & Service technician.
My air conditioner is working, but it produces a strange odor. Why?
Air conditioners, like most equipment, must be clean in order to function properly. Over time, bacteria and mold can accumulate in your system. When this happens, your local Best-One retailer can help you rectify the problem with a good cleaning.
When I turn on my air conditioner, I hear it running, but no cool air comes out.
This could be caused by a number of reasons: Your system could be low on refrigerant, or there could be a problem with the evaporator. Your local Best-One dealer can run specialized diagnostics tests to determine the problem’s source.
My car’s air conditioner is producing cold air, but it’s coming out the wrong vents.
When there is a problem with your car’s air distribution controls (which is the system that directs the air to either the dash, floor, or defrost vents), the air is directed to the floor or defrost vents by default. Typically, this happens when a vacuum line is loose, broken, or missing. A Best-One technician can help get your air conditioner running smoothly once again.
Do I need to recharge my A/C?
A car’s air conditioning system only needs to be recharged when the refrigerant is leaking. Over time, seals can dry out or break, especially if you do not use your air conditioning year round. It’s important to remember that your air conditioning unit should not leak, and if a leak is found it needs to be addressed immediately.
How do I make sure my car’s air conditioner is ready for the summer?
Regular maintenance is key. In order to avoid air conditioning problems before they start, have your air conditioning system checked on a routine basis—roughly every two years. Call your local Best-One retailer today to schedule an appointment to keep your car’s air conditioner running smoothly.
