Keeping this in consideration, why does my car AC not get cold?
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
Similarly, why is AC not cooling enough? Improve air flow. In addition to the air filter, your AC may have other types of air flow problems. If the evaporator coil is dirty, not enough air moves across it and your home doesn't cool off as well as it should. If the condenser coil is dirty, it won't dump enough heat to the outside.
Simply so, why is my AC blowing warm air in my car?
Hot air coming from your car AC vents can mean that you have low levels of refrigerant. It can also be due to a problem in the condenser, the compressor, the cooling fan, or the electrical system of your car.
Is it better to leave AC on auto or on?
The fan only runs when the furnace tells it to. On cooling, the fan will run only when the air conditioner is running. Pros. The "auto" setting means less energy usage, because it keeps the fan running the least amount of time at the slowest speed needed for heating and cooling.
