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

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

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

Technology advancements—There have been many 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 update both units.

Higher heating and cooling efficiency—Efficiency rankings are formed on matched unit performance. While adding a single new unit will improve 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 a matched system.

Equipment age—If your AC is 10 years old (or older), your heater is likely just as dated. Replacing both means you’ll enjoy a lot of of years of efficient comfort, no matter the time of year.

Updated warranty—A new set of units also means you’ll receive updated system warranties. You’ll receive peace of mind when you realize the warranty defends your total system for the same time period.

On the surface, replacing only your cooling system or heater can seem like a smart decision. But it’s not a very good choice when you consider reduced efficiency.

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