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

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

Matched design—Your furnace. This can help improve energy efficiency and performance.

Technology enhancements—There have been a lot of recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these perks year-round when you upgrade the whole system.

Better heating and cooling efficiency—Efficiency rankings are determined on corresponding system performance. While getting one new unit will enhance 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 dated. Changing 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 get peace of mind when you know the warranty defends your complete system for the same period of time.

At first glance, installing just a new AC or heating system might 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 get much higher efficiency, reliability and comfort for years to come in Elkhart.
