    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!

    If it's an older unit, you are most often better off not throwing good money after bad. Get several quotes in writing and spec the unit you want so everyone's bidding Apple's, not oranges.

    A 2007 heat pump is near the end of its designed life span, since a heat pump operates year round.
    $1000 to replace a TXV is a bit high.
    I'd go with Trane, Carrier ... well-known brands, made in the USA.
    I'm not really keen on Goodman .. They're ok for the price, but can be a bit troublesome.
    Since you might live there someday, put in the highest efficiency unit that you can afford ... soon.
    The high-efficiency machine will cost your tenant a lot less to operate, making it possible for you to charge a higher rent.
    Be sure to install a good surge protector on the outdoor unit, and the indoor air handler.
    Powerline surges are the biggest killer of motors (including compressors) that I know of.
