Hey guys, this is my first thread after the introduction thread. This is my first home that I'm looking to turn into a rental property so I can make a few bucks to supplement my income. On one hand I don't want to get the nicest available because I won't be paying the bill; on the other hand I may choose to live in the house at some point and I still want to have it be a nice place to live for people and not have them have to worry about things breaking down. The house is about 1600 sq. feet with a 2007 3-ton Rheem/Weatherking heat pump/air handler. I'm just now learning these terms, so please be gentle with me. The HVAC was only barely running, so after several visits from different companies it was determined that we need the TXV/expansion valve replaced. This costs anywhere from 900-1500 to replace. However, since the whole unit is basically near the end of it's life (could die tomorrow, could go a few more years) I'm not sure what the best route to take is. We could: -replace the valve for $1000 and hope for the best -replace the whole 3 ton shebang for about $4000 -buy a used unit and pay someone to replace it. There are several on Craigslist from new to 6 years old: https://richmond.craigslist.org/ppd/d/new-heat-pumps-air/6735882938.html https://richmond.craigslist.org/fod/d/30-ton-heat-pump-system/6728226443.htmlhttps://richmond.craigslist.org/app/d/bryant-preferred-3-ton-16/6741217404.html https://richmond.craigslist.org/app/d/carrierbtu-3-ton-ductless/6702914998.html I assume I should just go through a company and get the $4000 dollar complete package/install and add a $500 10-year warranty on parts/labor. Any advice or guidance is Greatly Appreciated!
