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

Our answer is, it’s a wise method. Here's why.

Coordinated design—Your furnace is designed to work with a matching air conditioner. This can help better energy efficiency and performance.

Technology upgrades—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these perks year-round when you update the full system.

Higher heating and cooling efficiency—Efficiency ratings are based on corresponding unit performance. While adding one new unit will enhance performance, efficiency will be lower from what it was designed to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your air conditioner is 10 years old (or older), your furnace is likely just as outdated. Changing both means you’ll enjoy a lot of of years of efficient comfort, regardless of the time of year.

New warranty—A new set of units also means you’ll receive up-to-date system warranties. You’ll get peace of mind when you know the warranty defends your total system for the same time period.

At first glance, installing just a new air conditioner or furnace might feel like a smart decision. But it’s not quite a good choice when you include decreased efficiency.

Installing an entirely new system might be more expensive, but you earn much better efficiency, reliability and comfort for many years in Edmonton.
