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

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

Matched design—Your furnace is created to function with a corresponding air conditioner. This may help improve energy efficiency and performance.

Technology upgrades—There have been many recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these benefits year-round when you update the full system.

Improved heating and cooling efficiency—Efficiency ratings are formed on corresponding equipment performance. While installing a single new unit will result in better 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 a matched system.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as outdated. Changing both means you’ll enjoy many years of efficient comfort, whatever the season.

New warranty—A new system also means you’ll have updated product warranties. You’ll receive peace of mind when you realize the warranty protects your whole system for the same time period.

On the surface, getting only a new AC or heating system can feel like a bargain. But it’s not quite a good decision when you factor in reduced efficiency.

Replacing an entire system could cost more, but you get much better efficiency, reliability and comfort for years to come in the Wasatch Front region.
