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

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

Paired design—Your furnace is designed to run with a paired air conditioner. This may help enhance energy efficiency and performance.

Technology upgrades—There have been a lot of recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll receive these perks year-round when you improve the full system.

Improved heating and cooling efficiency—Efficiency levels are based on corresponding equipment performance. While getting a single new unit will enhance performance, efficiency will be lower from what it was designed to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your cooling system is 10 years old (or older), your furnace is likely just as dated. Switching both means you’ll enjoy lots of years of efficient comfort, whatever the weather.

Updated warranty—A new system also means you’ll receive new system warranties. You’ll get peace of mind knowing the warranty protects your whole system for the same period of time.

At first glance, installing just a new air conditioner or heater can feel like a bargain. But it’s not a very good decision when you consider lower efficiency.

Installing an entirely new system may be costlier, but you earn much better efficiency, reliability and comfort for years to come in Raleigh.
