I have a 19 year old Carrier furnace and AC.
The AC has failed - tech says low coolant.
Rather than pay for him to hunt down and repair the leak on a 19 year old unit I have decided to replace it with a Carrier 24APA530A31
I have some questions concerning the new indoor coil.
My current furnace (also 19 years old but still working) is the Carrier Infinity 58SXB80. It is 17 inches wide.
I will likely replace it with a new Carrier Infinity when it eventually fails. I'm hoping to get another 5 years out of it.
My Carrier dealer says the furnaces in the current Carrier line with 80,000 BTUs are typically 21 inches wide. Hard to say what the "typical" width will be when my furnace is evantually replaced
If I put a new 17 inch coil on my current 17 inch furnace, what do I do when I replace the furnace with a 21 inch wide unit? Can I put the 17 inch coil on a 21 inch furnace? what are the pros and cons?
Can I put a 21 coil on my current 17 inch furnace? This would likely "future proof" it. What are the pros and cons to this approach?
Should I put a 17 inch coil on my 17 inch furnace now and change it out for a 21inch coil (or whater the appropriate size is at that time) when I eventually replace the furnace. What are the pros and cons?
Thanks in advance
