- Room Temperature Air. One of the most characteristic symptoms of low freon is the presence of room temperature air blowing from the vents.
- Visible Leaks. Of course, another sign of low freon levels is a visible leak.
- Clutch Doesn’t Engage.
- Ice on Compressor.
How much does it cost to put Freon in your car?
Freon is one of the core components in the air conditioning systems of many older cars, and will need to be replaced on a regular basis to keep the AC functioning properly. Freon replacements costs between $187 – $261 at most garages, with the freon itself costing between $57 – $120.

How much does it cost to refill freon in car?
The cost is luckily not extreme, nor should your Freon need to be replaced on a regular basis. For between $100 and $150, you can get a refill which should last for many years. Usually when a professional refills the Freon, he will also check to make sure the system is functioning properly.

The refrigerant starts out as a gas in the low pressure side of the system, and is converted into a liquid in the high side. The constant circulation of refrigerant through the high and low pressure sides of the system is what keeps the vehicle cool.
Why is my car air conditioner blowing hot air?
Like having a blocked condenser, having broken cooling fans can cause a lack of cooling at your condenser and could cause your car AC blowing hot air. These small leaks can cause your air conditioning system to stop blowing cold air.
