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

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

Coordinated design—Your furnace is created to work with a matching air conditioner. This can help improve energy efficiency and performance.

Technology advancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these advantages throughout the year when you update both units.

Higher heating and cooling efficiency—Efficiency levels are based on corresponding equipment performance. While adding a single new unit will enhance performance, efficiency will be decreased from what it was engineered to be. And your savings will not be as large as they’d be with matching equipment.

Equipment age—If your cooling system is 10 years old (or older), your heater is likely just as old. Replacing both means you’ll have lots of years of efficient comfort, whatever the weather.

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

At first glance, getting only a new air conditioner or heating system could appear to be a bargain. But it’s not quite a good choice when you include decreased efficiency.

Replacing an entire system might be costlier, but you receive much higher efficiency, reliability and comfort for many years in Louisville.
