I'm looking to change out my whole A/C system. Since I'm in Texas, I'd like to do it in the winter or, at least in the next couple of months, would rather be recommended, or should I wait until summertime?

Still need parts and to buy a vacuum pump for said repair

It's hard to test for correct function if it's too cold, and it can be hard to get the orings in when they're cold and stiff, but being Texas I'm guessing your cold isn't that cold.

It'll be fine.

Oh yeah that's fine. I'm from the mountains so "cold" is anything under 30 lmao A/C doesn't work that cold. But at 60 it'll be fine.

If you're going off the gauges instead of just dumping in the required amount of refrigerant for the system as designed, you might have to top it up in full summer as the ambient temperature may not allow you to charge the system without getting it overcharged. It's tricky aiming for the right pressure at lower temperatures, easy to under/overshoot.

Also, if the system has been at ambient pressure for long, replace the reciever/dryer as it might be saturated. And replace the test port schraders, they're very often the source of leaks in AC systems.
