Why does my car AC not work in hot weather?

The hotter it is outside, the harder the air conditioning in your vehicle has to work. Rising outside temperatures put extra strain on your entire vehicle and its cooling system, from the battery and belts to hoses and fluids, requiring each part to work overtime to keep your vehicle cool.

How can I make my car AC colder?

Why doesn’t my AC get cold when it’s hot?

This happens when your air filter is unclogged and can do its job correctly. However, if the airflow is low, or if it isn’t blowing over the evaporator coil at all, none of that heat is absorbed. Instead, the home gets hotter and hotter, and the refrigerant in the coil (which has no heat to absorb) won’t warm up.
