It doesn’t do you any good to turn on your car’s air conditioner if it blows hot air. Summer is upon us, and you’re ready to stay nice and cool inside your automobile. Advantage Auto Service advises that there are common problems that can cause your air conditioner to blow hot air instead of cold air. One of these problems may prevent your air conditioner from working at all. What are these problems? We’re going to list all four reasons why your car’s AC is blowing hot air below.
1. Low Refrigerant Levels
The most common reason why the AC blows hot air instead of cold air is a problem with the refrigerant. It could be that you have low refrigerant levels, especially if you haven’t had your vehicle’s air conditioner serviced in a long time. The refrigerant starts in gas form and is compressed to liquid form to cool the air before it is blown into your vehicle’s cabin. If there isn’t enough refrigerant, the air will not cool down.
2. Malfunctioning Compressor
Another common problem is a malfunctioning compressor. The compressor can break down if it isn’t used enough. This sounds strange, but it’s true. If you haven’t run your air conditioner in a long time, it’s possible that the compressor needs to be replaced. The compressor is what compresses the gas refrigerant into liquid form. Your air cannot be cooled down without a functioning compressor.
3. Malfunctioning Condenser
The condenser can malfunction because it can be damaged easily by road debris. This is because the condenser is located directly behind your vehicle’s grille. It gets pelted by any road debris that can fit through the slats. This debris cannot only dent the condenser and cause it to malfunction, but it can also clog the condenser, which will also result in hot air blowing through the vents.
4. System Electrical Problems
Finally, your air conditioning system might be having electrical problems. There may be a problem with the wiring, the relays, or even the fuses. This can prevent your air conditioner from turning on it all. In fact, one common problem is the button that you push to turn on the AC has died. Electrical system problems can also prevent the air conditioning fans from working. Instead of getting hot air blowing through your vents, you may not get any air blowing through your vents.
