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

Our response is, it’s a good method. Here's why.

Matched design—Your furnace is designed to run with a corresponding air conditioner. This may help enhance energy efficiency and performance.

Technology upgrades—There have been a lot of recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these benefits throughout the year when you improve the complete system.

Better heating and cooling efficiency—Efficiency ratings are calculated on corresponding system performance. While putting in a lone new unit will improve performance, efficiency will be lacking from what it was designed to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as dated. Switching both means you’ll receive many years of efficient comfort, regardless of the weather.

Updated warranty—A new set of units also means you’ll have valid equipment warranties. You’ll have peace of mind when you realize the warranty covers your entire system for the same amount of time.

At first glance, replacing only your AC or heating system may appear to be a smart decision. But it’s not a very good choice when you include reduced efficiency.

Replacing an entire system could cost more, but you get much more efficiency, reliability and comfort for long into the future in Oklahoma City.
