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

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

Matched design—Your furnace is made to work with a corresponding air conditioner. This can help improve energy efficiency and performance.

Technology advancements—There have been abundant 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 whole system.

Better heating and cooling efficiency—Efficiency rankings are determined on matching system performance. While getting one 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 large as they’d be with matching equipment.

Equipment age—If your air conditioner is 10 years old (or older), your furnace is likely just as outdated. Switching both means you’ll receive many years of efficient comfort, whatever the weather.

Updated warranty—A new set of equipment also means you’ll get new product warranties. You’ll receive peace of mind when you realize the warranty protects your complete system for the same amount of time.

On the surface, installing just a new cooling system or heating system might seem like a good decision. But it’s not quite a good decision when you consider lower efficiency.

Installing an entirely new system may be more expensive, but you get much higher efficiency, reliability and comfort for years to come in Elkhart.
