What happens when only one component of your split-system A/C starts acting up? Although you may think that you can simply replace the failing unit, there’s more to it than that. By taking the time to understand why a correct match is important, you’ll save yourself a lot of stress and expensive problems down the road.
A mismatched air conditioner means trouble
When the indoor coil and outdoor condensing units of your split-system A/C were manufactured, they were designed to work as a team. This team is what ensures that your air conditioner operates at maximum efficiency. When the team is split up, however, serious problems can ensue.
Here are two primary reasons why a mismatched system can cause so much trouble:
- Refrigerant — Your current air conditioner probably relies on R-22 as its refrigerant. New A/Cs, however, use non-ozone depleting refrigerants such as R-410A. Unfortunately, two components that use different refrigerants aren’t compatible. Attempting to force them to work together will result in a reduction in system efficiency and the stress could lead to premature system failure. And because installing a poorly-matched until will invalidate any warranties you may have, you could end up with a lot of out-of-pocket expenses.
- Efficiency ratings — As of 2006, all air conditioners must have a SEER (seasonal energy efficiency ratio) rating of at least 13. If your current equipment was installed before this deadline, it may have a lower efficiency rating than the new minimum standards. Installing a high-SEER component to work with a low-SEER unit is a bad idea. As the two units struggle to work together, overall system performance levels will drop and undue strain will be placed on the equipment. This can lead to higher utility bills and costly repairs.
By working with your HVAC professional for a proper match, you can avoid these complications and be eligible for tax credits and rebates.
