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

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

Paired design—Your furnace is designed to work with a corresponding air conditioner. This may 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 running. You’ll receive these perks all year when you update both units.

Higher heating and cooling efficiency—Efficiency rankings are based on matched unit 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 equipment.

Equipment age—If your cooling system is 10 years old (or older), your furnace is likely just as outdated.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

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

At first glance, replacing only your cooling system or heater might appear to be a smart decision. But it’s not a great decision when you consider decreased efficiency.

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