Can I replace refrigerant myself?

Aside from the dangers of handling refrigerant if you aren't familiar with it, replacing your own freon is also illegal. That's right. Due to the rise in popularity of “huffing,” or recreationally inhaling refrigerant to get high, improper handling of freon is an offense punishable by law.

Where do you add refrigerant?

Locate the refrigerant fill port on the low pressure side of the system. This will have a small plastic lid with an L printed on the top. Unscrew this cap to reveal the port.

Do you add refrigerant to the high or low side?

Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.

How often do you need to add refrigerant to AC?

Never. You shouldn't have to “add” refrigerant to a central air conditioner because it doesn't “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.

Can I add Freon to my AC unit myself?

It's possible to add Freon to your air conditioner unit yourself, but you'll need some general knowledge about ACs and a few specific tools to do it correctly. The process can be dangerous, so hire a qualified professional if you feel unsure about what to do.

What happens if you run out of refrigerant?

Alternatively, you can continue to run your air conditioner on low levels of refrigerant, and put your cooling system at risk. Your air conditioner will lose too much cooling power, and the compressor will suffer damage as it tries to function without the assistance of refrigerant.

What happens if you run your AC without refrigerant?

Although an air conditioner can still function at lessened cooling power after it loses refrigerant, it will start to sustain serious damage that will eventually lead to larger repair needs and possibly a full system breakdown.

How much should it cost to replace refrigerant?

High discharge temp.
High subcooling in the condenser.
High pressures in the condenser.
Higher condenser splits.
Normal-to-high evaporator pressures.
Normal superheats.
High compression ratio.

What happens if you put AC recharge in the high side?

The damage from trying to charge on the high side would be to you - not the system. More than likely the pressure would back up into the can and explode it like a grenade. If you don't know what you're doing, seriously get someone to help out. You ALWAYS want to connect to the low side.

Which refrigerant line is which?

Refrigerant Lines The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.
