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

Our reply is, it’s a great idea. Here's why.

Paired design—Your furnace is made to work with a paired air conditioner. This may help enhance energy efficiency and performance.

Technology enhancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these advantages year-round when you improve the complete system.

Better heating and cooling efficiency—Efficiency rankings are calculated on corresponding system performance. While getting a single new unit will result in better performance, efficiency will be decreased from what it was engineered to be. And your savings will not be as big as they’d be with a matched system.

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

Updated warranty—A new set of units also means you’ll get up-to-date system warranties. You’ll receive peace of mind when you know the warranty covers your entire system for the same time period.

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

Installing an entirely new system may cost more, but you get much better efficiency, reliability and comfort for years to come in Concord.
