Also to know is, do you add refrigerant to the high or low side?
The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY'S SAKE.
Also, how do you know if your central air needs freon? Here are 5 things to look for that might tell you that your AC needs more refrigerant.
- Your AC runs all day and never cools your home.
- High energy bills.
- Air coming out of vents isn't very cold.
- There's ice on your refrigerant lines.
- Hissing/bubbling noise.
- Note: Don't forget to fix the leak.
In respect to this, how often does Freon need to be added to AC?
If everything is working properly, your AC should never need refrigerant. In fact, a central air conditioner should never need refrigerant added unless there's a refrigerant leak.
