I have a 98 Toyota Tacoma with 270k miles. Some guy that had this truck before me. He rebuilt the ac compressed on the truck and he said it blows cold, but it was during the winter time when he was fixing it. By the way he did say be a mechanic. Then summer hit. It does take while to start blowing cold, but it doesn’t blow ice cold. I was thinking it needs refrigerant, but I want to make sure that what it needs. 😊

What are the high and low system pressures?
The only way to really know that you have the correct amount of refrigerant is to evacuate and recharge it with the manufacturer specified amount by weight.
You can open the hood and start the truck on a hot day. Put the AC on max. If you hear a clicking sound when you walk in front of the truck, the refrigerant is probably low. Take it to a mechanic who specializes in HVAC systems. Air conditioners are quite dangerous if the proper steps aren't taken. I did a job working on my air conditioner, but it took all day, and I read everything I could before starting. I'm an aspiring engineer. A normally functioning AC system has around 250 PSI on the high side, which is a lot of pressure, and most of the internals are made of metal.
So I did not hear any clicking when I went by my truck any other suggestion you have
Hooking up your manifold gauges and knowing the ambient temperature should help us understand what's going on.
