The Importance of a Matched System
Your cooling system consists of an outdoor unit (the condensing unit) and an indoor unit (air handler). These two components are designed to work together as a coordinated team to provide top performance, maximum efficiency, and comfort. Whenever you install a new outdoor unit, you should install a new, equally efficient “matched” indoor unit at the same time. While replacing the outdoor unit only may initially offer you the lowest price, it may prove more expensive over time.
When your air conditioning components don’t match, your system may still work, but it won’t perform at the promised energy efficiency. In fact, your system could be up to 15 percent less efficient than stated. You may be sacrificing comfort, as well, as a mismatched system may have difficulty keeping up on the hottest days. Finally, if your cooling system’s components aren’t matched, it could create undue stress on your cooling system, resulting in unnecessary, premature failure.
