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

Our response is, it’s a smart approach. Here's why.

Matched design—Your furnace is made to function with a matching air conditioner. This might help better energy efficiency and performance.

Technology upgrades—There have been many recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these advantages year-round when you upgrade both units.

Improved heating and cooling efficiency—Efficiency levels are formed on corresponding equipment performance. While putting in one new unit will improve performance, efficiency will be lower from what it was designed to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as old. Replacing both means you’ll receive a lot of of years of efficient comfort, regardless of the time of year.

Updated warranty—A new system also means you’ll get valid system warranties. You’ll receive peace of mind knowing the warranty covers your entire system for the same amount of time.

At first glance, getting only a new air conditioner or furnace might feel like a good decision. But it’s not a great bargain when you factor in lower efficiency.

Replacing an entire system could be costlier, but you earn much higher efficiency, reliability and comfort for many years in Austin.
