Hello, my vehicle started blowing hot air through all the vents yesterday. I wanted to try recharging my A/C. I looked under the hood and said the refrigerant charge my car uses is HFC-134A. I wanted to know if I use RF-134A would that cause any damage?

Using RF-134a in your Subaru's A/C system should be safe and compatible. Here is a video of how the job is done and I have included where the service port is so you can check the refrigerant levels.
