Are you dealing with a car AC that seems to be blowing only hot air? Don’t worry – this is a common problem, and there are a few things you can do to fix it. In this blog post, we’ll discuss the reasons why your AC may be blowing hot air, as well as some tips for getting back the refreshing cool air you’re used to. So if you’re experiencing an issue with your AC in car blowing hot air, read on to learn what you should do!
How Does My Car AC Work?
The air conditioning system in your car helps to keep you cool and comfortable when driving, regardless of the temperature outside. It does this by drawing in warm air from the inside, cooling it down, and then blowing it back into the cabin. The AC system works by using a combination of special gases and a compressor that circulates refrigerant throughout the system. The compressor circulates the refrigerant to help absorb heat from the inside of your car, cooling it down before blowing it back into the interior. By understanding how your car’s AC works, you’ll have a better idea of why your car is blowing hot air instead of cool air.
Understanding Why Your AC in Car is Blowing Hot Air
If your car’s AC is blowing hot air instead of cool, there could be a few potential issues that need to be addressed. Here are some of the main causes of an AC in car blowing hot air – and how you can identify them.
Lack of Refrigerant
One possible cause for an AC in car blowing hot air is a lack of refrigerant. Over time, refrigerant can leak out through tiny cracks or holes in the system, which can lead to an insufficient level of coolant within the car’s AC system.
Low refrigerant levels usually occur due to a leak, but they can also happen as a result of improper installation or manufacturing defects.
The most common sign that you’re dealing with low refrigerant levels is if your AC in car is only blowing hot air, or if it takes longer for the cabin to cool down after starting up your engine. You may also hear strange noises or smells coming from the vents when the AC is running.
Issues with the Compressor
Another potential issue causing your AC in car to blow hot air is an issue with the compressor. The compressor helps circulate refrigerant throughout the system and allows cold air to flow through your cabin – so if it fails, your passengers will likely feel uncomfortable and hot inside your car!
Compressor failure typically occurs due to lack of lubrication or overuse, but it can sometimes happen unexpectedly due to faulty wiring or components that were improperly installed during manufacture.
In addition to feeling cooler air coming from the vents than usual, you might notice strange noises coming from under the hood while using the AC in car – such as hissing or grinding sounds. These noises could indicate that something’s wrong with the system’s compressor. Additionally, if you smell burning near where the compressor should be located when you’re running your AC, this could also mean that there’s a problem that needs to be fixed.
Clogged Air Filters
The air filters in your vehicle are responsible for keeping dirt and debris out of your ventilation system. However, over time these filters can become clogged with grime and dust particles, which can impede airflow and cause poor cooling performance from your vehicle’s A/C unit.
Clogged air filters are often caused by neglecting regular maintenance checks on them. However, they may also be caused by outside pollutants such as pollen or industrial pollutants entering your vehicle’s interior through open windows or doors while driving down unclean streets or highways without any protective barriers like screens on them.
The main sign that you may have clogged air filters is reduced airflow coming from vents while operating A/C mode within your vehicle. Additionally, you may experience weak cooling performance even when set at high fan speed settings indicating that something else may need attention within the climate control system itself in order to function properly.
The condenser is an important part of the AC system in your vehicle and helps to remove heat from the refrigerant before it enters the evaporator. If it’s damaged, it can reduce airflow and cause cooling problems.
A damaged condenser can be caused by a variety of things, including road debris, dirt and dust buildup, corrosion, or even physical damage due to an accident or collision.
The main sign that you may have a damaged condenser is reduced airflow coming from the vents while using A/C mode in your car. Additionally, you may experience weak cooling performance even when set at high fan speed settings indicating that something else may need attention within the climate control system itself.
Electrical issues can also lead to poor performance from your vehicle’s AC system. If there’s a problem with any wiring or connections, this can prevent the compressor or other components from working correctly and decrease the amount of cool air coming through your vents.
Electrical problems typically occur due to loose connections, corroded wires, or faulty parts; however, they can sometimes happen unexpectedly due to manufacturing defects or improper installation.
If you’re experiencing decreased airflow from your vents while using A/C mode within your car, this could indicate a possible electrical issue with either the compressor or another component within the system. You may also hear strange noises coming from under the hood when running AC, which could mean that something’s wrong with one of its electrical connections.
Broken Cooling Fans
Cooling fans help draw in outside air into your car’s engine bay. If they’re not working correctly, then they won’t be able to properly circulate air around your vehicle and cool down its interior temperature as efficiently as they should!
Broken cooling fans are often caused by a lack of lubrication or overuse. However, they can also sometimes occur due to faulty wiring or parts that were improperly installed during manufacture.
As well as feeling cooler air come out less strongly than usual when using A/C mode in your vehicle, you might notice strange noises coming from underneath the hood when running AC, which could mean that one (or more) cooling fans have failed. You may also smell burning near where these fans are located if there’s something wrong with them.
Dirty Air Filter
Dirty air filters allow dirt and debris into your car’s ventilation system. This impairs airflow and decreases the cooling performance of your AC unit.
Dirty air filters are usually caused by neglecting regular maintenance checks on them. However, they can be increased by contaminated outside pollutants such as pollen entering into your vehicle’s interior through open windows or doors while driving down unclean streets or highways without any protective barriers like screens on them.
The main sign that you may have dirty air filters is reduced airflow coming from vents while operating A/C mode within your vehicle. Additionally, you may experience weak cooling performance even when set at high fan speed settings indicating that something else needs attention within the climate control system itself for the issue to get fixed.
What to Do When Your AC in Car is Blowing Hot Air
Feeling the heat while driving? Your car’s air conditioning system may be blowing hot air instead of cool. Here’s what you can do:
1. Check for Simple Solutions
Before panicking and looking for an AC specialist, start with the basics. Check if the AC switch is turned on and verify that the air is flowing properly. Sometimes, the air ducts may be blocked, so make sure they’re clean and clear.
- Check Your Thermostat Settings. Another possible cause for hot air blowing out of your car’s AC is incorrect thermostat settings. Make sure you have set the temperature to Cool and the fan to Auto. Also, check your car’s manual to understand the thermostat settings better.
- Inspect Your AC’s Air Filters. Clogged air filters can cause warm air to circulate instead of cooling the air in the car. Check your AC’s air filters and replace them if necessary. Clean air filters also make your car run more efficiently.
- Check Your Car’s Fuses. If none of the above solutions work, move on to checking the fuses. If a fuse is blown or damaged, the AC won’t work correctly. Replace the fuses if necessary, but if you’re not confident doing this, take it to a mechanic.
2. Get a Professional AC Inspection
If you have exhausted all options above, it’s time to call a professional. Here’s what to expect during an AC inspection:
Questions to Ask Your AC Technician
