The air conditioning system in your home or office is very similar to how vehicle A/C works. While some of the mechanical components function a bit differently, the A/C in a car, home, or office all serve the same purpose: to cool the air and remove moisture. A car air conditioner “conditions” the air inside the cabin to keep you comfortable.
You may think that the car A/C system creates the cold air that pours from the vents. In reality, it’s more accurate to say that the A/C in cars and trucks removes heat from the existing air inside the vehicle.
If there’s an odd smell coming from your A/C, there may be mold inside the system. The presence of mold likely means there’s water inside the system where there shouldn't be. It may be that you have a damp and dirty A/C filter that needs replacing or a blocked drain inside the evaporator. Bring your vehicle into your nearest Firestone Complete Auto Care to find and eliminate the source of the unwelcome smell.
If your car air conditioner is only blowing hot air even on “max A/C” mode, it could be that there's a refrigerant leak, the compressor has stopped working, or the fans have stopped working. Additionally, there may be widespread internal failure of the system —though this option is the worst case scenario. When moisture mixes with refrigerant, it combines to make a highly corrosive substance that eats away at the inside of your A/C system. The rubber seals will usually be the first parts to fail, which can compromise cooling and let in more moisture.
From there the acid may corrode the compressor and other parts, spreading harmful metal debris throughout the system. Eventually, what started as a little moisture and hot air could result in complete failure of the A/C system. If your vents are blowing hot air, bring your car in for A/C service and repairs before things get worse.
Weak air flow —or no air flow at all —may indicate blockage somewhere in the A/C system, restriction in the evaporator core, or the blower motor is failing.
