You can find a replacement for your outside AC unit at most home improvement stores. Be sure to get one that is the same size and type as your old one.

There are a few places you can look for a replacement AC unit. If you have an HVAC contractor, they may be able to sell or install a new AC unit for you. You could also check with home improvement stores like Lowe's or Home Depot - they may have AC units available for purchase or rental. Finally, you could check online retailers like Amazon or Ebay to see if there are any available units that would work for your home.
