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

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

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

Technology upgrades—There have been a lot of recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these advantages year-round when you update the whole system.

Better heating and cooling efficiency—Efficiency rankings are based on matched unit performance. While adding a lone new unit will enhance performance, efficiency will be decreased 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 time of year.

New warranty—A new set of units also means you’ll get new equipment 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 great decision when you factor in reduced efficiency.

Replacing an entire system could cost more, but you earn much higher efficiency, reliability and comfort for long into the future in Kitchener.
