Your Split A/C System: Why the Right Match Is Crucial

Posted by Paul Wadsworth on Mon, Apr 29, 2013 @ 12:05 PM

Your split A/C system needs to operate in perfect harmony for optimal efficiency and performance. If one of the components is out of tune, the entire system — and your household cooling costs — will suffer.

pk wadsworthA typical split A/C system consists of an indoor unit composed of the air handler and evaporator coil and an outdoor unit that houses the compressor and condenser coil. The outside components are connected to the inside ones with an engineered set of copper tubes called the refrigeration line set. Though separated both physically and by function, these components are designed for each other and engineered to work as a team. When upgrading your split A/C system, the temptation to economize by replacing only one part of the system while leaving older equipment in place is understandable. However, that’s actually an example of false economy that usually produces substandard results.

Here are some reasons to replace all components in a split system:

  • New A/C components usually incorporate advanced technology not fully compatible with components in the existing system. By only replacing some parts and not others, the system may continue to deliver outmoded efficiency and performance, preventing you from enjoying the benefits of improved technology.
  • Unmatched components may work against each other and cause excess wear and tear on both the new and the old components. This can increase the likelihood of expensive repairs and reduced service life.
  • Recent changes in refrigerant standards for air conditioners require that environmentally-friendly R-410A refrigerant must be incorporated in all new units. None of the major components in old air conditioners that utilize R-22 refrigerant are fully compatible with R-410A. This means that upgrading some elements of an R-22 split system requires replacement of all components.  
  • Federal minimum SEER (seasonal energy efficiency ratio) ratings for new air conditioners were increased to 13 in 2006. To meet this new standard, all components in a system should be upgraded. Upgrading the whole system is the only way to ensure that you’re operating at the new minimum efficiency standard, as well as getting all the performance benefits of the higher SEER rating.
