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

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

Paired design—Your furnace is designed to function with a corresponding air conditioner. This may help improve energy efficiency and performance.

Technology enhancements—There have been many recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these perks year-round when you update the full system.

Higher heating and cooling efficiency—Efficiency ratings are determined on matched system performance. While adding one new unit will enhance performance, efficiency will be lower from what it was envisioned to be. And your savings will not be as large 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. Replacing both means you’ll have lots of years of efficient comfort, no matter the time of year.

Up-to-date warranty—A new set of units also means you’ll receive updated product warranties. You’ll get peace of mind when you realize the warranty protects your whole system for the same amount of time.

At first glance, replacing only your AC or furnace could feel like a smart decision. But it’s not quite a good decision when you consider lower efficiency.

Getting an entirely new system may be more expensive, but you receive much better efficiency, reliability and comfort for years to come in Haltom City.
