108. My furnace is only 12 years old but the A/C compressor has to be 20 plus.

I'm waiting for the other shoe to drop. And when it does, I may spend the $3-4k on a highly efficient mini-split. Versus the same amount on an old fashioned compressor ducted system.

I can probably install it myself (hard core DIYer semi-pro here). The 220 power is already on the roof and the minis come pre-charged with refrigerant. Evacuating, testing and purging the system takes some knowledge and specialized tools I would have to purchase. I'll never use those tools again if I have to purchase them. I may go it on my own or find someone with tools that I can trust to do the refrigerant piece for a fee.

We had a handful of super cold days here so a natural gas furnace is nice to have. Even in the absence of a "real" furnace, my understanding is the minis will heat - just not as efficiently. The mini kicks in to "emergency" mode and heats with a heating element.

Do you have a ductless mini-split? Hassin Bin Sober Jul 2012 #65
