Are there any benefits in going with R22 systems at this point? The unit is a Trane 14i heat pump. The air handler is going to be installed in a second story attic. The lineset will not be replaced (flushed). One of my main concerns is the cost of R22 going up. Trane gives a pretty decent warranty, but it does not cover refrigerant costs. The other downside to an R22 system is that there is an option to replace just the condenser in the future if I go 410a. This shouldn't be that much of a concern though. By the time the warranty runs out, the air handler will need to be replaced. There are situations, however, where the whole condenser would need to be replaced (hurricane damage, etc.).
Are you guys still installing a lot of R22 systems? I just wanted to see what the pluses and minuses are.
