Deciding whether to repair or replace your malfunctioning air conditioner is not an easy decision to make. Replacing an old conditioner with a new one takes a large initial outlay of money. On the other hand, repairing an air conditioner that continues to break down needing repeated repairs can cost even more in the long run. While most homeowners invest in a replacement of their air conditioner if the cost of the repairs is more than 50% of a new air conditioner there may be other things to consider when faced with repairing or replacing your current air conditioner.
