is this exclusively for R410A systems or can I use it on my vacation house R22 system

This can be used on either R410a or R22 systems.

How long should we wait before adding R410a to my AC?

Until it can hold the pressure from the sealer am I fat

How difficult or dangerous would be to add R410a to your own AC?

If your existing AC system is R-22 it would be very dangerous. If your existing system is R-410A, I recommend having a certified technician adjust the R-410A charge in your system to OEM specifications.

After 4 years my system started leakign again,13 degrees across the coil instead of 20+. Can I recharge and add another can again?

YOU CAN ADD ANOTHER CAN BUT THIS ONLY GOES SO FAR. TAKE YOUR BLACK LIGHT & SEE HOW MANY AND WERE YOUR LEAKES ARE. IT MAY BE TIME TO BITE THE BULLET & REPLACE THE UNIT!
