Nothing is more uncomfortable than riding around town in a car with a broken A/C. The air conditioning system is one of the most complex systems in the vehicle. There can be several causes for your air conditioning system blowing warm air. Take a look at these common causes.
A refrigerant leak is one of the most common causes of an air conditioning system blowing warm air. Refrigerant is a liquid that circulates through your car’s air conditioning system. As it moves through the system, it removes heat and humidity from the cabin. When it doesn’t have enough refrigerant, the system won’t work properly. As a result, it will blow warm air. A refrigerant leak can be caused by several things, so it’s best to have an auto technician check to identify the cause of the leak.
Your air conditioning system has a condenser that is responsible for keeping refrigerant cool so that the system can pull heat and humidity from the cabin. If the condenser is broken and can’t do its job, it means that your cabin will remain warm. Condensers can be blocked or clogged by road debris, and as a result, air can’t reach them, and the refrigerant can’t cool correctly. This problem can be fixed by looking through your vehicle’s grate to look for any debris. If none is present, it can mean that the condenser has broken.
Clogged Air Filter
Did you know that clogged air filters can result in your air conditioning system blowing warm air? Air filters are responsible for filtering out insects, dust, sand, and other debris from reaching the engine and ensuring a good mixture of air and fuel is available to support performance. Air filters need to be cleaned or swapped out regularly. So if you can’t remember the last time you changed your filter and your air conditioning system is blowing warm air, try cleaning the air filters first.
If all the A/C components are in working order, your car may be blowing warm air because of an electrical problem. Frayed wires or a blown fuse can prevent a healthy air conditioning system from working properly. If it is an electrical issue, you’ll want to bring your car to a trusted local auto mechanic so they can inspect your car’s fuse box and wiring.
