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 created to work with a paired air conditioner. This might help improve energy efficiency and performance.

Technology upgrades—There have been abundant recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these perks year-round when you improve the whole system.

Better heating and cooling efficiency—Efficiency rankings are based on matched unit performance. While installing a lone new unit will result in better performance, efficiency will be lower from what it was engineered to be. And your savings will not be as much as they’d be with matching equipment.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as old. Switching both means you’ll enjoy many years of efficient comfort, regardless of the weather.

New warranty—A new system also means you’ll receive valid system warranties. You’ll get peace of mind knowing the warranty covers your whole system for the same time period.

It would appear installing just a new air conditioner or furnace can appear to be a good decision. But it’s not a very good choice when you include lower efficiency.

Replacing an entire system could cost more, but you earn much higher efficiency, reliability and comfort for many years in Kitchener.
