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

Our answer is, it’s a smart idea. Here's why.

Coordinated design—Your furnace. This can help better energy efficiency and performance.

Technology advancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these benefits all year when you update the whole system.

Better heating and cooling efficiency—Efficiency levels are based on matching system performance. While putting in a single new unit will improve performance, efficiency will be lower from what it was engineered to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your cooling system is 10 years old (or older), your heating system is likely just as old. Changing both means you’ll have lots of years of efficient comfort, no matter the season.

Updated warranty—A new set of units also means you’ll get updated system warranties. You’ll get peace of mind when you know the warranty covers your complete system for the same amount of time.

It would appear replacing only your air conditioner or furnace could seem like a smart decision. But it’s not a great decision when you factor in reduced efficiency.

Getting an entirely new system could be more expensive, but you receive much more efficiency, reliability and comfort for many years in Shreveport.
