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

Our response is, it’s a good 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 enhancements—There have been a lot of recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these perks throughout the year when you update the full system.

Higher heating and cooling efficiency—Efficiency levels are based on corresponding equipment performance. While adding a single new unit will result in better performance, efficiency will be decreased from what it was envisioned 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 heating system is likely just as old. Replacing both means you’ll have lots of years of efficient comfort, whatever the weather.

Up-to-date 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 complete system for the same period of time.

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

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