It does you no good to have your car, truck, or SUV’s AC blow hot air out of the vents. Sellers Automotive can inspect the air conditioner each spring to ensure it will perform flawlessly throughout the summer. We can look for the problems we are going to list below, so you can avoid hot instead of cold air in the passenger cabin. Here are the reasons why car ACs blow hot air.
Dead Compressor
The compressor is a workhorse that will malfunction if it isn’t used frequently. The compressor takes the original form of the system’s refrigerant, gas, and turns it into a liquid by compressing it. Once the refrigerant is a liquid, the compressor will circulate the refrigerant through the air conditioning system. If the compressor has died due to non-use, you will end up with no liquid refrigerant circulation. The refrigerant is what makes the air cold as it blows through the vents.
Damaged Condenser
The refrigerant gets hot after it absorbs the air’s heat to cool it off. Once it is hot, it is circulated into the condenser where it is cooled off by a fan and air inlets. The air flowing through the grille flows through the inlets because the condenser is right there. The fan also reduces the refrigerant’s temperature. The condenser can be damaged and clogged by road debris and dirt.
Faulty Condenser Fan
The condenser fan can also be damaged by road debris, and if this happens, it may not turn on to cool off the refrigerant. You may hear the fan turn on and off as needed while your car’s air conditioner is running. If you have hot air and no fan sounds, the condenser fan is malfunctioning.
Electrical System Problems
Electrical system problems could be to blame for the malfunctioning condenser fan. If there is a short, blown fuse, or another problem in the electrical system, the condenser fan may not run at all. In fact, your vehicle’s air conditioner may not turn on at all if the electrical system has failed.
Low Refrigerant Levels
Finally, you will not get cold air flowing out of the vents if the AC’s refrigerant levels are too low or non-existent. This is why we recommend an AC check each spring. The inspection gives us a chance to add refrigerant to the system if it needs it and to confirm the system is not leaking.
