I recently bought a house but had my external AC/heat pump unit stolen on the night of closing. Now the house has an 06-07' Carrier with model number FA4CNF042 for the air handler in perfect shape (R-22/TXV) with a factory installed heater as well. I was hoping to figure out two things. (1)Can I get any brand heat pump for the missing outside unit (2) What is the recommended tonnage for the heat pump that goes with this air handler for a house that has 1900 sq ft living space. Any other specs I should be looking for as I start my search on Craigslist and elsewhere...
I also found this document online that is the product data sheet. Of course, I wasn't sure of the info as a lay person but was hoping this will help you decipher my question.
Kind regards and thank you all for your time!
