Top Reasons Why Car AC is Blowing Warm Air
A car’s AC is not only complex but also an important part of a vehicle. The reasons a car’s AC is blowing warm air can be different. Due to hot or extreme weather, a car’s AC can face many issues which can lead to malfunctioning. It can be very unpleasant for anyone facing a similar problem.
Top 7 Reasons Why Car AC is Blowing Warm Air
Following are some of the most common reasons why a car’s AC is blowing warm air instead of cool:
Refrigerant Leak
Refrigerant is a liquid that is found in your car’s AC system. It is responsible for removing heat and humidity by expanding and contracting from the cabin. Leakage in refrigerants can lead to warm air blowing.
Without proper refrigerant levels, AC components will not work properly. An old hose or punctured evaporator can cause a leak. It’s not easy to spot because it evaporates in open space.
Faulty Condenser
The refrigerator absorbs the heat and humidity that the AC system collects from the cabin. It functions as a cooler to keep the refrigerant cool to let the cycle go smoothly. If the condenser is unable to perform its task of keeping the refrigerant cool, the cycle breaks, and it leads to hot air blowing. Because of the condenser’s place, road debris can get blocked or clogged; air won’t reach it, resulting in warm air blowing.
Broken Compressor
Being the heart of your car’s AC, the compressor works as a transporter to circulate the refrigerant through the system. The antifreeze will not reach the condenser and will not cool the cabin if there’s a problem with the compressor.
Compressor issues can happen if AC isn’t used for a long time due to any reason. A broken compressor can lead to the car’s AC warm air blowing, resulting in frustration for the car owner.
Electrical System Problems
If you check and all your AC components are working fine, then it means your car’s electric system is facing a problem. A frayed wire or a blown fuse can cause AC problems if other AC parts are working fine, and it can cause hot air to blow in, turning the AC on. Electrical system problems can occur due to any issue, resulting in AC malfunctioning along with other issues.
Broken Cooling Fans
A damaged cooling fan could be one of the reasons why car AC is blowing warm air. Cooling fans help remove heat from the refrigerant fluid and are a great help in AC functioning. If any one of the two cooling fans leaks or is damaged due to any reason, the refrigerant will not get cooled properly, and your air conditioner will blow warm air.
A broken or damaged pair of fans can happen due to any reason, including flying road debris, that can lead to AC malfunctioning.
Dirty Air Filter
Almost every car has a cabin air filter installed in it. Just like any other filter in the world, it gets clogged with dirt and other materials like debris. Regular filter changing is necessary to let it work properly. Air filter blockage can cause car AC to blow warm air. If you hear loud noises or rusty ones, it means your air filter is blocked.
Wrong Thermostat Settings
The thermostat settings can greatly affect your car’s AC system. Children can be so naughty, and they can surely change thermostat settings when you leave them alone in the car, even for a very short time. This can result in discomfort or even damage to your vehicle’s cooling system. Always check the thermostat settings before making any results. It can save you time going to the workshop, ensuring that your car’s AC is functioning optimally. If you suspect any issues, such as inconsistent cooling or strange noises, it’s wise to schedule a car AC repair appointment promptly to address any potential problems.
Conclusion
There can be a lot of reasons why car AC is blowing warm air. The reasons include refrigerant leaks, faulty condensers, broken compressors, broken cooling fans, or electrical system problems. These problems don’t have any specific reason, but it can happen at any time. Therefore, it’s essential to consider the condition of your car’s AC system and promptly seek assistance from Carglassfixer.com if needed to ensure optimal performance and comfort while driving.
FAQs
Why is my AC blowing warm air in my car?
When your car’s AC blows warm air, there could be several issues, such as refrigerant leaks, faulty compressor or compressor clutch, blocked air vents, faulty thermostats, broken cooling fans, and other issues.
Why is my car’s AC not cooling while running?
Leaks or compressor issues are some of the well-known reasons for broken air conditioning. If your car is blowing hot air, you should check your clogged filter, cooling fan problem, or radiator.
How do you diagnose a car AC problem?
Start your vehicle and turn on the AC with the fan on high. Then, go through your HVAC selector options and feel for cold air from everywhere. Positions that don’t blow cold air could have a temperature sensor issue.
Should I turn off the AC if it is blowing warm air?
You should first try to turn off your car’s AC unit. Running the unit while your condenser is not working well can result in further damage.
