Low freon levels can cause your car’s AC to weaken or even fail altogether. Thankfully, there are a few signs drivers may notice when this issue occurs.
How Does Car AC Work?
Freon is a chemical (refrigerant) designed to provide cool air throughout the cabin. Without the presence of freon, there is no way to circulate this cool air.
Freon begins as a gas on the low-pressure side of your AC system prior to being converted to a liquid on the high side. The car will be cooled by the constant circulation of this refrigerant through the high and low-pressure sides of the system.
Unfortunately, leaks can occur within the system as it ages. Freon and/or pressure levels can begin to decline, which results in a decreased output of the AC system overall. The system can fail if the issue of low refrigerant remains unfixed.
What Are The Signs Your Car Is Low On Freon?
There are three noticeable signs associated with low freon levels in a car. When freon levels are too low, it’s time to recharge the AC. Let’s go over the indicators below.
Hot Air Coming From The AC
One of the most obvious signs of low freon is when your car AC is blowing hot air inside the cabin.
Your AC system operates by circulating this pressurized refrigerant, meaning it will ultimately impact the AC’s performance when freon levels decrease.
Refrigerant Leaks
If you notice a leak that appears thin and greasy, this is likely a result of low freon levels.
In most cases, these leaks will be found under the hood around the compressor, beneath the car, or inside the cabin. It’s always best to take your car to a trusted auto care professional whenever you see leakage.
Clicking Sound When Turning On AC
By listening closely, you may be able to hear a clicking noise when the AC system is turned on. This sound is heard when the clutch is engaged.
The clutch, however, may fail to engage when freon levels fall too low. When this happens, it means there is not enough refrigerant for the compressor to pressurize.
What To Do If Your Car AC Freon Levels Are Low
Your best move is to have the auto care professionals properly diagnose this issue. They will inspect the AC system’s pressures with gauges while actively looking for leaks. The issue will then be repaired and topped off with fresh refrigerant.
