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

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

Paired design—Your furnace is created to run with a matching air conditioner. This can help enhance energy efficiency and performance.

Technology advancements—There have been abundant recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll receive these perks all year when you improve the whole system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matching unit performance. While installing a lone new unit will enhance performance, efficiency will be decreased from what it was designed to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as old. Replacing both means you’ll receive a lot of of years of efficient comfort, whatever the season.

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

It would appear getting only a new AC or heater might feel like a smart decision. But it’s not a great decision when you factor in reduced efficiency.

Getting an entirely new system might be more expensive, but you get much better efficiency, reliability and comfort for many years in Mobile.
