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

Our response is, it’s a great approach. Here's why.

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

Technology enhancements—There have been abundant recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll receive these perks throughout the year when you upgrade both units.

Higher heating and cooling efficiency—Efficiency rankings are based on matching system performance. While putting in one new unit will improve performance, efficiency will be decreased 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 dated. Switching both means you’ll enjoy a lot of of years of efficient comfort, whatever the time of year.

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

On the surface, replacing only your cooling system or heating system can appear to be a good decision. But it’s not quite a good choice when you consider decreased efficiency.

Installing an entirely new system might be more expensive, but you earn much higher efficiency, reliability and comfort for many years in Charlotte.
