An Old AC Unit is Inefficient

• If you fix your air conditioner, either yourself or by paying a paid professional, then you are left with an unreliable, inefficient machine. The air conditioning will likely break down in the future, leaving you without air conditioning while you wait for repair or unit replacement. A new AC unit can pay for itself in energy savings and is much less likely to break down.
  
  

An Old AC Unit Works

• Perhaps you do not have the money to purchase new air conditioning. If you live in a small space, the cost of air conditioning may be minimal, making energy savings take longer to build up. An old unit may also have a large life of operation ahead of it. The initial cost of the unit must be considered when making this decision.
  
  

Bottom Line

• If you use air conditioning to cool a large space, its worth the initial down payment because the energy saved will pay for the new unit's cost. If you are low on money or a unit has a long operational life ahead, it will benefit you more to fix the old unit.
