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

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

Paired design—Your furnace is designed to work with a paired air conditioner. This might help improve energy efficiency and performance.

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

Higher heating and cooling efficiency—Efficiency levels are formed on matched equipment performance. While putting in one new unit will improve performance, efficiency will be decreased from what it was designed to be. And your savings will not be as large 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 dated. Changing both means you’ll enjoy a lot of of years of efficient comfort, no matter the season.

Up-to-date warranty—A new set of units also means you’ll receive new equipment warranties. You’ll get peace of mind knowing the warranty protects your whole system for the same time period.

On the surface, replacing only your AC or heating system might appear to be a smart decision. But it’s not a great decision when you consider decreased efficiency.

Installing an entirely new system may cost more, but you get much higher efficiency, reliability and comfort for long into the future in Edmonton.
