Auto AC Repair in Denver, CO | Rev Auto & Truck Repair

Q: How often should Freon be changed?

Never, at least not in the way you think of your oil being changed. Your car's AC system is a sealed unit. No new Freon needs to be added unless there's a refrigerant leak. Over time as your vehicle ages small cracks may form in your AC system parts such as the compressor, condenser, evaporator, receiver-dryer, expansion tube and connecting hoses allowing Freon to escape. If this occurs, you need to replace the failing part and have your Freon recharged.

Q: How long should a Freon recharge last?

If your car's AC system was recently repaired and required a Freon recharge it should not need to be replaced again. Your AC system is a closed or sealed system that does not allow Freon to escape. Freon is not like gasoline; it does not get depleted. If Freon is escaping after your car's AC system has been repaired, then additional work may need to be done to find the leak.

Q: How many cans of Freon does a car take?

Don't guesstimate your car's refrigerant needs! Most use 28-32 ounces (2-3 12oz cans), but larger vehicles and rear A/C can be different. Check your manual for the exact amount to avoid overfilling.

Q: Can I leave my car running when adding Freon?

It is advised to have your engine running while recharging your car's A/C system. This is essential as the A/C compressor, powered by the engine, must be active to facilitate proper refrigerant circulation and ensure an effective recharge.

Q: Why is my car blowing hot air after adding Freon?

A refrigerant leak can lead to a loss of pressure in the AC system, resulting in a failure to produce cold air. This is frequently the primary reason a recharge may prove ineffective. It is crucial to inspect the system for leaks and address any issues before proceeding with a recharge.

Freon Recharging FAQs

How often should Freon be changed?

Freon in your car's AC system doesn't need regular replacement like engine oil because the system is sealed. However, over time, as your vehicle ages, small cracks might develop in components like the compressor, condenser, or hoses, leading to Freon leakage. In such cases, the damaged parts should be replaced, and the Freon should be recharged.

How long should a Freon recharge last?

A properly repaired and recharged car AC system shouldn't need new Freon unless there's a leak. Unlike fuel, Freon doesn't deplete with use but can escape through leaks. If you find the Freon level dropping after a repair, it's crucial to check for and repair any leaks.

How many cans of Freon does a car take?

The amount of Freon required varies by vehicle. Typically, a car needs between 28-32 ounces of Freon, which equates to about 2-3 standard 12oz cans. However, larger vehicles or those with rear AC systems may need more. Always refer to your vehicle's manual to ensure the correct amount and prevent overfilling.

Can I leave my car running when adding Freon?

Yes, your car's engine should be running when you recharge the AC system. The AC compressor operates by using the engine which circulates the refrigerant and is essential for a successful recharge.

Why is my car blowing hot air after adding Freon?

If your car is still blowing hot air after adding Freon, it likely indicates a leak which causes a drop in system pressure and inefficacy in cooling. Before adding more Freon, it's advisable to thoroughly check for leaks and repair any found to ensure the system can maintain proper pressure and function effectively.
