The chemical freon or simply you can call it coolant is the reason why the ac cools hot air quickly. The ac compressor pumps refrigerant around in the ac system for it to cool properly.

The most common cause of a car air conditioner blowing hot air sometimes is due to a refrigerant leak. If your car ac is blowing hot air, you can safely assume that one of the components is faulty. A refrigerant leak is unique in the sense that refrigerant evaporates instantly into a gas once it isn't under the pressure of your closed loop a/c system.

That’s why our team wrote this helpful guide to figuring out what’s going on with your car’s ac, regardless of whether it’s a honda or not. My car ac only works for about an hour and it starts blowing warm air thereafter, the first ac guy said it needed recharging which i did recharge, yet the problem persisted, another said there is a leakage in the evaporator,from much research i believe my air vent had accumulated a lot of leaves and other organic debris that probably have clogged my evaporator. A refrigerant is a liquid that circulates into the air conditioner system by expanding and contracting to eliminate heat in the cabin.

Over time, small parts in the a/c wear down or are damaged, causing leaks in the system. The other two reasons for blowing hot air in the condenser are blockage in the pipe and broken condenser. However, this could also be a result of a problem with your car’s electrical system.

The blockage in the pipe or anywhere in the tube can result in the improper operation of the condenser. I have a toyota corolla 2003. Generally speaking, a lack of refrigerant is the most common cause of your ac system only blowing warm air.

Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system. If the ac compressor fails, you often have to flush the whole ac system afterward because there might be metal pieces everywhere. In this way, hot refrigerant remains to be hot.

Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. Tim’ll fix it tim shallcross used to train aa patrols to fix cars. If there is an insufficient amount of refrigerant is circulating through the system, then excess heat won't be properly extracted from the air.

The refrigerant passes into a part called compressor, which pumps it. Why is my car ac blowing hot air? Low refrigerant level due to leaking.

Similarly, the fluid refrigerant continues to remain hot in the passenger compartment too. Sometimes, it’s the cooling fans that are broken. The most common cause of an ac system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser.

If the fan is faulty, the system may still blow cold air when the car is moving, because air is flowing through the radiator. Three signs your a/c is malfunctioning. But it is not the only cause;

Like having a blocked condenser, having broken cooling fans can cause a lack of cooling at your condenser and could cause your car ac blowing hot air. Other reasons could be a faulty compressor and/or condenser. The fans could actually be broken, like a burnt out motor, bad mount a chipped fan blade, or they could simply have an electrical problem like a blown fuse or burnt out relay.

The most common comfortable temperature people want inside their car goes anywhere between 20 to 22c (68 to 72f). The lack of refrigerant is the major reason why your car ac could be blowing hot air. For your ac to work effectively, it must receive its fuel, which is the refrigerant.

Your car’s air conditioner is supposed to provide you comfortable cool air inside the cabin, but if your car’s a/c is blowing hot air, there must be something wrong with the system. Let's look at some of the potential reasons why your air conditioning isn't blowing cold. Thus, ac would not work, as there is no freon in the system.
