When substituting the outdoor system, should the indoor unit also be replaced?

Our reply is, it’s a wise idea. Here's why.

Matched design—Your furnace is designed to run with a corresponding air conditioner. This can help better energy efficiency and performance.

Technology enhancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these perks all year when you upgrade both units.

Improved heating and cooling efficiency—Efficiency rankings are based on corresponding equipment performance. While adding a lone new unit will improve performance, efficiency will be lower from what it was envisioned to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your air conditioner is 10 years old (or older), your furnace is likely just as old. Changing both means you’ll have a lot of of years of efficient comfort, regardless of the weather.

Up-to-date warranty—A new set of equipment also means you’ll get updated equipment warranties. You’ll get peace of mind when you know the warranty covers your whole system for the same amount of time.

It would appear getting only a new air conditioner or furnace might seem like a smart decision. But it’s not a great choice when you include reduced efficiency.

Getting an entirely new system may cost more, but you earn much more efficiency, reliability and comfort for many years in Memphis.
