Always Clean Your Air Filter
Your air filter will accumulate dust and dirt, just like your AC unit at home. To make sure that your AC works at its best, do the following:
- Clean the air filter at least once a month
- Check your car user manual for instructions on how to remove the air filter
- Clean with soap and water and then replace
Repair Small Leaks With An Ac Leak Sealer
These products usually cost between $30 to $50 and are great for smaller leaks. They come in a compressed can with a nozzle that connects to the low-pressure port. They remain a liquid until they encounter a leakage point, at which point they seep out and form a seal. Unfortunately, they can also lead to issues, like decreased AC performance or clogs in the receiver drier.
- Clutch Cycling Switch Failure
As mentioned earlier, the clutch is in charge of engaging the compressor, which converts the refrigerant from gas to liquid. Usually, when you turn on the AC, you will hear a clicking sound, followed by cold air. If this doesnt happen, its likely the clutch. However, this usually stems from further issues, such as a faulty compressor or a fuse that has blown.
Sadly, replacing a compressor clutch is somewhat complicated. It is possible to do it yourself, but it might be better to take it to a professional if you dont have any mechanical experience. Expect to spend between $700 to $800 for the entire replacement .
- Blocked/Broken Condenser
If you read through our explanation of how your AC system works, then you understand how significant the condenser is. If its clogged or faulty, then the refrigerant wont convert from gas to liquid, which is a vital step in the process.
If it turns out you need a new condenser, the cost of hiring a professional range from about $450 to just under $1,000 .
- Fan Motor Failure
- Compressor Issues

Reason #1 You Have A Leak
Your A/C system in a car is very similar to the cooling system in a refrigerator, and the refrigerant is a liquid coolant that helps the system cool the air and keep your A/C blowing cold. Sometimes an A/C system can get low on refrigerant and cause your A/C to blow only cool or warm air. This can happen over time as your car gets older and the system becomes well used. However, the A/C system is a self contained system and most of the time should not lose refrigerant at all, and if it does, it should lose it at an extremely slow rate. Therefore, most often if your vehicle is low on refrigerant, it means you have a leak.
Sometimes refrigerant leaks are very very small and difficult to detect, and for very small leaks there is no need to replace the entire system. You can simply apply a sealant to the leak to eliminate the problem. Professional mechanics can help you identify and fix leaks in your A/C system and will do a complete drain and recharge procedure on your A/C to identify and fix the leak and then refill the system with new refrigerant. This can be more expensive, but a good option if you know you have a major leak. Or you can fix a leak yourself using self recharge kits, like Mr. Freeze, which have sealant in the product to help seal off micro leaks.

Is Your Condenser Dirty
The outdoor part of your air conditioner is called a condenser. When dirt and debris get in there, it interferes with the process.
Your air conditioner will have to work much harder to pull in air and cool it. Its very similar to the problem youll experience with a clogged filter.
Luckily, cleaning up your condenser is something you can do on your own but you have to be very careful not to bend of break anything.
We recommend using soap and water to gently wipe away the dirt. You can also use a hose with a gentle pressure.
To minimize dirt and debris in the future, invest in a good weatherproof cover for when your air conditioner is not in use. You should also keep the area around the condenser weeded, trimmed, and clear of overhanging branches and other plants.

No : Your Car Has A Refrigerant Leak
This is one of the most common causes of car A/Cs not working. Leaks can originate from a number of different places it could be the result of rubber seals and hoses breaking down over time, and that allows the refrigerant, Freon, to escape. The bigger danger when this happens goes beyond not having cool air in your car, but those weak spots can also allow moisture to get inside your cars cooling system and mix with the refrigerant. When moisture and Freon mix together, they create a dangerous acidic combination that can corrode your A/C system and cause permanent damage.
As with any type of leak, you want to get this fixed quickly so it doesnt continue causing problems for your car.

Either way, the malfunction will need to be corrected to get the system operating properly again. This job can be easy or difficult depending on ones mechanical ability and tool availability. It is likely for a qualified mechanic.

No : Your Cooling Fans Are Broken
Just like you need blowers to push the air conditioning through the vents in your home, your car uses cooling fans to move the refrigerated air into your vehicles cabin. When theres a problem with the fans, you wont feel any air coming out of the vents.
Cooling fans can stop working properly for a number of different reasons they might have blown fuses, an electrical short, or could have been cracked by debris from the road. Fortunately, this is fairly simple to fix your mechanic should be able to replace it quickly and get you back on the road.
How An Ac System Works
Your AC system consists of a compressor, a compressor clutch, a condenser, a drier, a blowing fan, and an evaporator. While Freon used to be the primary refrigerant, it was discontinued in the US in early 2020 due to being bad for the environment. In its place is Puron , which is a safer alternative that doesnt deplete the ozone .
The refrigerant starts out in a gaseous form in the compressor. When you turn on the AC, it tells the clutch to engage the compressor. The compressor raises the temperature and pressure of the refrigerant and sends it to the condenser. The condenser then condenses and cools down that gas , converting it into a liquid state.
This liquid then gets sent to the receiver drier, which removes harmful contaminants and moisture. It does this by using a material known as Desiccant, which absorbs moisture that may have found its way into the AC system from the humidity in the air.
The refrigerant is still in a liquid state when it leaves the drier. But before it reaches the evaporator, it passes through either an orifice tube or an expansion valve. An orifice tube is a fixed nozzle that converts refrigerant from liquid to gas . An expansion valve, however, has moving parts that adapt to readings sent from the evaporator.

Common Reasons Why Your Cars Ac Is Not Blowing Cold Air
- Low on Refrigerant Steps to Refill
The most common reason your cars AC is not blowing cold air when its hot outside is due to a lack of refrigerant. If youve read through our explanation of how the system works, then you understand how crucial it is to the process. A full tank usually lasts for a few years, depending on how often you run the AC.
Thankfully, adding more is simple. The first thing youll need is an AC manifold gauge, which costs around $40 and can be found either online or at a local auto supply shop. You can complete the job without one, but you are likely to over or under fill the compressor. The other thing youll need is a can of refrigerant, which costs between $50 to $100.
If your cars AC is still not blowing cold air after a recharge, its likely a clog in the system or a faulty part.
- Refrigerant Leak
Faulty Ac Pressure Switch
There are two AC pressure switches in your car that monitor the high-pressure side and the low-pressure side of the air condition system for safety reasons.
If the pressure gets too high it will stop the AC compressor from cooling the system anymore because of safety reasons.
If the pressure gets too low, it will also shut off the function of the AC compressor.
If this AC pressure is faulty, it can give the AC compressor faulty signals to stop even if it shouldnt, and this will cause your AC system not to function at all.

Car A/c Not Blowing Cold Air After Recharging The System
Skip to the good stuff:
Hi my name is Matt.
The other day I found that the AC in my car not blowing cold air like it used to when I bought it. So I figured Id write a quick article to help any of you that may be dealing with a vehicle AC not blowing cold air after recharge.
It used to be that car air conditioning systems were standard equipment only in expensive luxury marquees. But nowadays, even the cheapest small cars are equipped with standard A/C from the factory. If the A/C in your vehicle is well-maintained and serviced regularly, you can expect it to continuously cool the cabin when you need it most.
But there are times the air conditioner will not blow cold air even after recharging the system. What could have gone wrong? In order to fully understand the possible cause of charged ac still warm, it is important to understand how an air conditioning system works.
The Condenser Device Is Obstructed
The condenser units exterior features a huge outdoor coil that stretches the majority of the way around the unit. The coil is made up of a number of thin metal fins that are very closely spaced.
A jammed or clogged condenser coil could be the cause of your air conditioner running but not dropping temperatures inside. The condenser fan pulls air into the outside device through the condenser coil to extract heat energy from your home while its working properly.
Dirt, grass, and other airborne particles will clog the coil by accumulating between the fins.
A dirty coil may result in lower energy efficiency, a loss of cool air at the registers, or, in the worst-case scenario, a full system shutdown or compressor damage due to overuse.
Clearing dirt, properly vacuuming the coil with a brush attachment, or softly rinsing the coil with a hose are all options for cleaning the coil.
