A properly working air conditioning system is necessary for keeping cool during the warm summer months. When you get into a hot car without A/C, you'll definitely be miserable. Now imagine getting into your vehicle on a hot day and blasting the A/C, only to find that it only blows hot air - not a pleasant experience!
So, why is your car A/C only blowing hot air? Let's look at some of the potential reasons why your air conditioning isn't blowing cold.
- Low refrigerant levels - this is the most common cause of warm A/C. If there is an insufficient amount of refrigerant is circulating through the system, then excess heat won't be properly extracted from the air. Typically, the only reason for low refrigerant levels is due to a leak.
- Condenser issues - the condenser is the component that actually removes heat from the refrigerant coming from the compressor. This is what cools down the liquid before it turns into a gas and is put through to your cabin. If the condenser is damaged, it prevents the process from working and the refrigerant will stay warm.
- Faulty compressor - the compressor is actually what drives the refrigerant throughout the air conditioning system. If the refrigerant doesn't move, then the system won't work.
- Bad cooling fan - if the cooling fans aren't working properly, they won't be able to remove heat from the refrigerant. The air won't be super hot, but it will be warm.
- Electrical issues - the A/C system actually requires electricity to run properly, so a wiring issue or circuit short can stop the system from working.
Low refrigerant is always the culprit when it comes to a faulty A/C system - you may find that you need a part replaced or are due for a recharge. Here at Honest Wrenches, we are your one-stop-shop for all of your car air conditioning repair and service needs. Stop by or give us a call today!
