When Replacing Units of Your Split-System A/C, Parts Should Match
Are you thinking about replacing part of your split-system A/C? Before going forward with any plans, it’s important to understand why finding the perfect match is necessary. Here’s a closer look at the value of performance matching and how to go about replacing your equipment.
Why are matched parts such a big deal in split-system A/Cs?
The manufacturer of your air conditioner took the time to precision-match its indoor and outdoor units for three reasons: efficiency, effectiveness and system longevity. If one unit begins to fail before the other, it may seem more economical to simply replace the problematic component, but unless you find a replacement unit that’s 100 percent compatible with your current equipment, the results could be disastrous.
How can I ensure that the components of my system are matched?
Because multiple factors go into finding a good match for your system, it’s smart to work with an HVAC contractor. Generally, however, refrigerant type and efficiency ratings must be identical in order for two units to be compatible with one another. Here’s why:
- Refrigerant — Attempting to put together two units that use two different refrigerant agents will put a lot of stress on your equipment. Ultimately, this results in decreased efficiency and could even lead to premature system failure. But finding a component with matching refrigerant may not be as easy as you think. Your current equipment probably uses R-22 refrigerant, whereas new units are being manufactured to rely on eco-friendly R-410A. If you can’t find a match, you’ll likely need to upgrade the whole system.
- Efficiency ratings — If your indoor unit has a low efficiency rating and you attempt to install an outdoor component with a high seasonal energy efficiency ratio (SEER), you’ll experience some problems. Contrary to what you may believe, the high SEER of one unit won’t increase system performance. In fact, the difference in efficiency ratings will create a struggle between the two system components, lowering efficiency or possibly leading to costly repairs.
