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

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

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

Technology enhancements—There have been many recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these advantages year-round when you improve both units.

Higher heating and cooling efficiency—Efficiency ratings are determined on matched system performance. While adding one new unit will enhance performance, efficiency will be decreased from what it was envisioned to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as dated. Replacing both means you’ll have lots of years of efficient comfort, regardless of the time of year.

Updated warranty—A new system also means you’ll get updated product warranties. You’ll receive peace of mind when you realize the warranty defends your whole system for the same amount of time.

At first glance, replacing only your AC or furnace may feel like a good decision. But it’s not quite a good decision when you consider lower efficiency.

Getting an entirely new system may be more expensive, but you earn much better efficiency, reliability and comfort for years to come in Fort Worth.
