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 is designed to run with a matching air conditioner. 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 perks all year when you update the full system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matched system performance. While installing a lone new unit will improve performance, efficiency will be lacking from what it was engineered to be. And your savings will not be as large as they’d be with matching units.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as old. Switching both means you’ll receive a lot of of years of efficient comfort, no matter the season.

Updated warranty—A new set of units also means you’ll have valid product warranties. You’ll have peace of mind knowing the warranty defends your entire system for the same period of time.

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

Replacing an entire system could be more expensive, but you receive much better efficiency, reliability and comfort for long into the future in the Niagara Region.
