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

Our answer is, it’s a wise method. Here's why.

Coordinated design—Your furnace is created to function with a corresponding air conditioner. This can help enhance energy efficiency and performance.

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

Better heating and cooling efficiency—Efficiency ratings are determined on matching system performance. While adding a single new unit will enhance performance, efficiency will be lacking from what it was engineered to be. And your savings will not be as much 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Equipment age—If your cooling system is 10 years old (or older), your heating system is likely just as outdated. Replacing both means you’ll have lots of years of efficient comfort, no matter the time of year.

New warranty—A new system also means you’ll get updated equipment warranties. You’ll get peace of mind when you realize the warranty protects your total system for the same period of time.

On the surface, replacing only your cooling system or furnace can appear to be a good decision. But it’s not a very good decision when you include decreased efficiency.

Installing an entirely new system could be more expensive, but you receive much higher efficiency, reliability and comfort for years to come in Charlotte.
