Central Ac / Heat

[Maria Car]

One of my rentals needs a new central ac unit installed , Need some opinions on a new or used

1) New Central  ( 4k)

2) Used Central ( 3 years old ) 2k

Has anyone had experience on having installed a used central ac on there Rentals. The Unit I have now is 20 years old , I got a quote on a new one for 4k and I  also got a quote  on a  used one that is only 3 years old.  Half the price.   Looking for advice if a used one is worth the money if its only 3 years old. I figure it may last 17 years , planning on keeping house for 5 years . I hate to cut corners , I am highly considering it because its a good brand that is only 3 years old. Anyways feedback is appreciated. thanks

Just a thought... If you know you will only hold this for 5 years, then a 3 year used unit is probably fine.  Don't count on 17 years, though, if it's based on your old unit.  You'll probably get as many say new as old, so spend my two cents carefully!  ;)

If you have an existing home warranty, you can get a repair or replace for almost nothing.  If not, you might want to consider one to cover your major systems.  For only $450 or so annually, it will probably pay for itself in the next 5 years.  

Good luck
