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

Our answer is, it’s a great approach. Here's why.

Matched design—Your furnace is made to run with a paired air conditioner. This might help improve energy efficiency and performance.

Technology upgrades—There have been many recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these benefits year-round when you update the full system.

Better heating and cooling efficiency—Efficiency ratings are based on matching 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 large as they’d be with a matched system.

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 enjoy many years of efficient comfort, whatever the season.

New warranty—A new system also means you’ll have updated product warranties. You’ll get peace of mind when you realize the warranty defends your whole system for the same time period.

At first glance, installing just a new cooling system or heating system can feel like a bargain. But it’s not quite a good choice when you include reduced efficiency.

Replacing an entire system could cost more, but you get much higher efficiency, reliability and comfort for years to come in the Wasatch Front region.
