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

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

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

Technology upgrades—There have been abundant recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these perks throughout the year when you upgrade the complete system.

Improved heating and cooling efficiency—Efficiency levels are formed on corresponding unit performance. While adding one new unit will result in better performance, efficiency will be lower 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 dated. Changing both means you’ll enjoy a lot of of years of efficient comfort, whatever the weather.

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

At first glance, getting only a new cooling system or heating system may seem like a smart decision. But it’s not quite a good choice when you include reduced efficiency.

Getting an entirely new system could cost more, but you receive much higher efficiency, reliability and comfort for long into the future in Calgary.
