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

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

Matched design—Your furnace is designed to function with a corresponding air conditioner. This might help better 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 have these benefits throughout the year when you update the complete system.

Improved 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 large as they’d be with matching equipment.

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

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

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

Replacing an entire system could cost more, but you get much more efficiency, reliability and comfort for many years in Oklahoma City.
