How do you know when your car needs Freon?
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.
Is Freon the same as coolant?
Key Differences Between Coolant and Freon Instead, coolant is designed to keep your engine cool and will remain in a liquid state within its system. On the other hand, Freon is a gas that is converted into a liquid and then back into a gas before creating the cool air you feel in the cabin when your car’s A/C is on.
Does it matter which Freon I use?
So, a good rule of thumb is if you own a vehicle that is newer than 1995 your engine should take R135a refrigerant, but if you have a vehicle older than 1995 you are going to be purchasing R12 refrigerant. If you are still concerned you might be using the wrong refrigerant, look under the hood.
Why is my BMW air conditioning not cold enough?
One of the most common reasons your BMW’s air conditioner isn’t working is because of an A/C leak. The fluid that is used to cool your car, freon, could be leaking out of your car, or there might be a bigger leak in the A/C system.

How long does Freon last in a car?
Most AC systems can last around five years without a Freon top-up, unless you live in a very hot climate. Freon is a kind of refrigerant that is recirculated in your vehicle in a closed system to cool down the interior. So, your car won’t really run out of Freon since it is reused inside the sealed system.
Why is AC recharge so expensive?
SUPPLY & DEMAND Much of the Freon you can buy today is actually reclaimed, meaning it was extracted from an old system before disposal. Since the supply is so low, but demand still remains fairly high, Freon prices are jaw-dropping.

What happens if Freon is low?
A low Freon charge can lead to compressor damage and overall inefficiencies of the air conditioning unit. This problem happens when the low refrigerant causes freezing on the evaporator coils. Eventually, the ice build-up leads to the insulation of the coils and slows the cooling process.
What are the symptoms of low Freon?
- It takes much longer than it should to cool off your home.
- Your utility bills are higher than usual.
- The air coming out of your vents isn’t cold.

How long is Freon supposed to last?
Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
How often do you recharge Freon?
In fact, most units only need to be recharged once every two to five years โ and sometimes even longer than that. The main exception to this rule is if there’s a leak in the system, which will cause the refrigerant level to drop over time.
