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

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

Coordinated design—Your furnace is designed to run with a matching air conditioner. This may help better energy efficiency and performance.

Technology enhancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these perks throughout the year when you update the whole system.

Higher heating and cooling efficiency—Efficiency rankings are determined on matching unit performance. While putting in a lone new unit will result in better performance, efficiency will be lacking from what it was designed to be. And your savings will not be as much as they’d be with matching units.

Equipment age—If your cooling system is 10 years old (or older), your furnace is likely just as dated. Replacing both means you’ll receive many years of efficient comfort, no matter the time of year.

New warranty—A new set of units also means you’ll receive up-to-date system warranties. You’ll receive peace of mind when you realize the warranty defends your total system for the same time period.

On the surface, getting only a new air conditioner or heating system may feel like a bargain. But it’s not quite a good decision when you consider lower efficiency.

Replacing an entire system might be more expensive, but you earn much more efficiency, reliability and comfort for many years in Austin.
