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

Our reply is, it’s a good approach. Here's why.

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

Technology advancements—There have been abundant recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these advantages all year when you upgrade the full system.

Better heating and cooling efficiency—Efficiency levels are formed on matched equipment performance. While getting a lone new unit will improve performance, efficiency will be lacking from what it was engineered to be. And your savings will not be as big as they’d be with matching units.

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

New warranty—A new set of equipment also means you’ll receive up-to-date system warranties. You’ll receive peace of mind when you realize the warranty protects your entire system for the same amount of time.

It would appear getting only a new air conditioner or heating system could appear to be a smart decision. But it’s not a great bargain when you include decreased efficiency.

Installing an entirely new system could cost more, but you get much more efficiency, reliability and comfort for long into the future in Roanoke.
