For the most part, air conditioner servicing is not usually top of mind when car owners are planning for car maintenance. As a result, this leaves many car air conditioners susceptible to repair issues, which develop over time due to neglect. Faulty car air conditioners can lead to hot car interiors, especially on sunny days. Here is a breakdown of repair issues associated with car AC systems:
The primary job of the condenser unit on your car's AC is to cool hot refrigerant (the working fluid in your AC system) so that the air supplied to your car interiors is cool enough. Over time, however, your condenser may get clogged with dirt and debris, and this will affect its ability to cool hot refrigerant. This will, in turn, undermine the cooling efficiency of your entire AC system. If your car AC is blowing hot air while your AC is turned ON, your condenser is one of the top culprits.
Bad cooling fan
If your car air conditioning system isn't cooling properly yet the temperature settings seem okay, your cooling fan could be failing. The cooling fan is typically found on the condenser, hence it is also known as the condenser fan. It is designed to blow cool air across the condenser unit, which needs to be kept cool so as to ensure efficient cooling within the entire air conditioning system. Issues with the cooling fan mean the cooling efficiency of your AC system will be compromised, so be sure to seek professional assistance if you notice that your AC isn't cooling as efficiently as it should.
Your car's AC system comprises many components and reduced cooling performance could also be due to problems with any other car AC system component. Problems with the compressor, valves, pressure switch, and fan belts will affect the operating efficiency of your AC system. If both your condenser and cooling fan are in good working condition, a qualified mechanic will diagnose the exact cause of the problem and provide the right solution.
There are many different things that can cause your car's AC to stop working efficiently. But proper auto AC system maintenance can go a long way towards ensuring the system keeps working reliably and keeps you cool for a long period. If you encounter any problems with your car's AC system, it is always best to inform a qualified mechanic right away.
