Hey guys, I'm hoping to get an informed opinion on how long you think R22 outside units will be available to add to an existing system.
My house and a/c system are 11 years old. I replaced the coil in November 2007. Yesterday, my system was not cooling. Our A/C tech came out and found that all the components were in working order and that the outside unit just didn't kick on likely due to a dirty/pitted contact.
While he was here, he informed me about the R22 phase out and suggested that if I want to keep the Trane coil I recently put in, I should go ahead and get a new Trane R22 condenser unit now before supplies run out. Apparantly Trane is no longer making them. The alternative would be to wait until my current 11 year old condenser/compressor fails, risk having no R22 replacement units available, and then have to spend more to replace both condenser and coil with R410a units.
So the choices seems to be either spend X dollars now for a non-heat pump R22 outside unit or possibly spend a higher amount for condenser/compressor and coil at some point in the future. What I am trying to figure out is how long I can wait to replace the outside unit before dealers run out of the R22 units.
