I think you can still get the r22 outside units but they are not pre-charged.
you can convert the inside unit to r410 if you can change the metering device. easy to do if you have a TXV, you just change the head.

we had a compressor changed at work, the guy put in a 410 comp that was previously r22. just change metering head and pressure switches.

I would also be leery of the "maybe 2 leaks' in the cond. get someone else out there,
have them show you the leak. they should either be able to show you with a leak detector or soap bubbles,


I put in a new HEIL system at my house. 4.5ton along with new duct. I think it was around 7-8K. I called my AC guy about the R22 to 410 swap they did at work and he said it was OK.

I think AC guys are some of the most crooked people out there, not saying all are. they can get away with it because most people no absolutely NOTHING about AC.
one of the guys I work with worked on AC before coming here. he said their company made them "up sell" work the customers did not need.

I do AC work but not for a living.

Good info, thx.
