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

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

Matched design—Your furnace. This can help better energy efficiency and performance.

Technology advancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll receive these advantages all year when you improve the full system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matched system performance. While adding a single new unit will improve performance, efficiency will be lacking 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 cooling system is 10 years old (or older), your furnace is likely just as old. Switching both means you’ll enjoy lots of years of efficient comfort, regardless of the season.

Updated warranty—A new system also means you’ll have new product warranties. You’ll have peace of mind knowing the warranty defends your complete system for the same amount of time.

On the surface, replacing only your cooling system or furnace can feel like a smart decision. But it’s not quite a good bargain when you consider decreased efficiency.

Replacing an entire system could be costlier, but you earn much higher efficiency, reliability and comfort for long into the future in the Niagara Region.
