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

Our answer is, it’s a wise idea. Here's why.

Coordinated design—Your furnace is made to run with a matching air conditioner. This might help enhance 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 receive these perks year-round when you update the complete system.

Better heating and cooling efficiency—Efficiency ratings are based on matched system performance. While getting a lone new unit will improve performance, efficiency will be lower 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 old. Changing both means you’ll have lots of years of efficient comfort, whatever the season.

New warranty—A new set of units also means you’ll have up-to-date system warranties. You’ll receive peace of mind when you realize the warranty defends your whole system for the same time period.

At first glance, getting only a new AC or heating system might seem like a bargain. But it’s not a great decision when you include lower efficiency.

Replacing an entire system could be costlier, but you get much better efficiency, reliability and comfort for many years in Wheeling.
