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

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

Coordinated design—Your furnace is made to work with a matching air conditioner. This can help better 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 have these perks all year when you improve the complete system.

Higher heating and cooling efficiency—Efficiency rankings are determined on matched system performance. While adding a lone new unit will improve performance, efficiency will be decreased from what it was engineered to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your air conditioner is 10 years old (or older), your heating system is likely just as dated. Changing both means you’ll have a lot of of years of efficient comfort, whatever the time of year.

Up-to-date 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 covers your whole system for the same period of time.

On the surface, getting only a new air conditioner or furnace may seem like a bargain. But it’s not a very good decision when you consider reduced efficiency.

Installing an entirely new system may be more expensive, but you earn much higher efficiency, reliability and comfort for long into the future in Belleville.
