Should I pull vacuum or just add a can of refrigerant?

[Tracy Ballard]

My 2008 honda accord V6 coupe that I bought 2 years ago with 72k miles has an AC that blows cold air when the weather is not too hot, but not as cool when it gets hotter. It was the same last summer when the weather started getting hot, you can feel a cooling effect, and it’s good enough for one person with both vents blowing on him, but it’s not up to standards. I’m about to work on it, but I can’t find my vacuum pump. Since I don’t suspect a leak of any kind, do I really need to evacuate the system, pull vacuum and do a complete recharge, or do you think just adding a can would fix this up? I would also need to buy a digital scale to do the recharge properly so I hate to do that, but if that’s what it takes so be it. thanks in advance!
