So what is the current status of being able to repair A/C systems that are R22? If the compressor or coils were to go out, could I replace them or would I HAVE to buy a whole new systems that is R410A? My home was built in November 2005 and I assume it is R22. Any easy way I can confirm this? (Edit: I verified my system is R22)

Knowing that my system is 12 years old, I am trying to plan for possible repair costs in the upcoming years. I was assuming the worse case scenario might be a $2000 repair to replace the compressor in the next few years. But, a friend was saying that I might have to replace the whole system because you can not get parts for R22 systems any more. Is this true?

If I did have to replace the whole system, what is a general cost for an average A/C system for a 2500 sq ft house?

There should be a label on the outside unit that specifies refrigerant type, among other things. 2005 was around the tipping point where 410a really started to take over.

We have a service which can help make that 12-year-old system more efficient than it was new and possibly add a few extra years to it.

OK, I confirmed my system is R22. So does this mean the next time I have a major repair that I might as well replace the whole system?

I just replaced my system. Previous system had R22 and was leaking.

Artic Air (Mike Waters - 281-222-5224) replaced it with a new 4 ton condenser and coils for ~$4500.

Others quoted my $7k+ for a new 4 ton and $4k to replace the coils and pump full of R22 with no guarantee it would work and just guessing how much R22 I would need ($100/gallon).

Replaced both my r22 heat pumps with r410a ones in the last couple years due to leaks. R22 phase out is real and will make recharging impossible in a few years. You may be able to get r22 parts but not recharge the system once they're installed or recharge after a leak.

One of Obama's last gifts to us was his support of the Kigali amendment to the Montreal Protocol. This adds HFC's such as r410a to a phasedown schedule similar to r22 but not a complete phase out. Hopefully Trump will be able to stop a possible phasedown of refrigerant we're all switching to.
