Your Split Air-Conditioning System: Why the 2 Sides Must MatchIf you’ve been thinking about replacing just a single component of your split air-conditioning system, you should re-consider. Although taking a short cut may seem to be the more affordable route now, it will end up costing you big time in the long run. By taking the time to understand the importance of properly matched cooling equipment you can save yourself from a lot of stress and expenses in the future.

What’s wrong with replacing only one component of my split air-conditioning system?

Replacing only the ailing component of your cooling system will only create problems for you. Here are four common complications that arise due to a mismatched split air-conditioning system:

  • SEER compliance – The seasonal energy efficiency ratio (SEER) of your current air conditioning system must be taken into consideration. Starting in 2006, all systems are required to achieve, at minimum, SEER 13. If your current equipment falls below this threshold, you can’t simply hope that the installation of one high SEER component will bring the whole system up to compliance. In reality, the opposite is true, and the overall SEER of the new component will be lowered.
  • Refrigerant – It’s likely that your current equipment utilized R-22 refrigerant. Recently, the federal government issued a directive that calls for the phaseout of R-22 in favor of non-ozone- depleting, EPA-approved refrigerants like R-410A. Integrating components that use different refrigerants will put a great deal of strain on the system, resulting in premature failure.
  • Efficiency – Mismatched equipment is unable to run efficiently which will ultimately cause a significant increase in your monthly utility bills.
  • Rebates & Incentives – If you’re hoping for a utility rebate or federal tax credit, both of your indoor and outdoor components must be properly matched. Often, you will need to prove that this is the case by requesting that your HVAC contractor provide you with a Certificate of Product Performance or a Certified Reference Number through the Air Conditioning, Heating, and Refrigeration Institute (AHRI).
