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

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

Matched design—Your furnace is made to function with a matching air conditioner. This may help enhance 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 have these advantages year-round when you upgrade the full system.

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

Equipment age—If your AC is 10 years old (or older), your heater is likely just as old. Replacing both means you’ll enjoy lots of years of efficient comfort, no matter the weather.

Updated warranty—A new set of units also means you’ll get valid equipment warranties. You’ll receive peace of mind knowing the warranty covers your complete system for the same period of time.

At first glance, installing just a new air conditioner or furnace might feel like a good decision. But it’s not a very good bargain when you factor in reduced efficiency.

Replacing an entire system could be more expensive, but you receive much better efficiency, reliability and comfort for long into the future in Austin.
