When Some Parts of Your Split-System A/C Need Replacing, Proper Matching Is ImportantIs one of the components of your split-system A/C giving you trouble? Though the idea of swapping out the ailing unit for a new one may seem more economical than upgrading your whole system, you should think twice before doing so. Here’s why carefully matching your equipment is imperative in achieving maximum performance levels.

Mismatching your split system A/C: A mistake you can’t afford to make
Both the indoor coil and outdoor condensing units of your A/C system were manufactured to work together as a team in order to achieve optimal efficiency and effectiveness. By replacing only one of these units, you have split up the “team.” Ultimately, this could lead to a lot of frustration and expenses down the road. Here’s a closer look at why:

  • Refrigerant – Like most older systems, your current air conditioner probably utilizes R-22 freon. The cooling equipment being manufactured today, however, is designed to rely on non-ozone depleting refrigerants like R-410A. Unfortunately, two systems that utilize different refrigerants will not work well together. Efficiency will be reduced, and undue stress will be placed on both system components. This may result in expensive repairs, or even premature system failure.
  • SEER – What’s the seasonal energy efficiency ratio (SEER) rating of your current equipment? If it’s lower than 13, it will be impossible for you to find a replacement unit with a compatible rating. As of 2006, all cooling equipment must have a minimum SEER rating of 13. And installing a high-SEER outdoor unit to work with a lower-SEER indoor unit (or vise versa) will not raise the overall efficiency rating of your system. In reality, the difference in efficiency ratings will cause your equipment to struggle, reducing efficiency and increasing the likelihood that you’ll need repair work.

Working with an HVAC professional to properly match your equipment will boost system performance and longevity. You could even save extra money by qualifying for rebates and tax credits.
