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

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

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

Technology enhancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll receive these advantages all year when you improve the full system.

Higher heating and cooling efficiency—Efficiency rankings are formed on matched unit performance. While installing a single new unit will improve performance, efficiency will be lower from what it was engineered to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as dated. Replacing both means you’ll receive lots of years of efficient comfort, no matter the weather.

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

At first glance, replacing only your cooling system or heating system can feel like a smart decision. But it’s not a very good decision when you consider reduced efficiency.

Getting an entirely new system may be costlier, but you receive much higher efficiency, reliability and comfort for years to come in Kitchener.
