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

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

Paired design—Your furnace is created to run with a paired air conditioner. This might help better energy efficiency and performance.

Technology upgrades—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these advantages throughout the year when you upgrade both units.

Better heating and cooling efficiency—Efficiency levels are determined on corresponding unit performance. While installing a single new unit will result in better performance, efficiency will be decreased from what it was designed 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 heating system is likely just as dated. Switching both means you’ll enjoy many years of efficient comfort, regardless of the season.

Up-to-date warranty—A new set of units also means you’ll have up-to-date equipment warranties. You’ll have peace of mind knowing the warranty defends your complete system for the same amount of time.

At first glance, getting only a new AC or heating system might appear to be a smart decision. But it’s not a very good decision when you include lower efficiency.

Installing an entirely new system could be more expensive, but you get much higher efficiency, reliability and comfort for long into the future in Voorhees.
