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

Our answer is, it’s a great approach. Here's why.

Paired design—Your furnace is created to function with a corresponding air conditioner. This may help enhance energy efficiency and performance.

Technology advancements—There have been many recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll have these advantages all year when you update the complete system.

Improved heating and cooling efficiency—Efficiency rankings are formed on matching equipment performance. While getting one 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 much as they’d be with matching equipment.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as outdated. Changing both means you’ll enjoy many years of efficient comfort, whatever the time of year.

Updated warranty—A new set of units also means you’ll have new product warranties. You’ll receive peace of mind when you know the warranty protects your total system for the same time period.

It would appear replacing only your cooling system or furnace may seem like a good decision. But it’s not quite a good decision when you factor in lower efficiency.

Installing an entirely new system could cost more, but you earn much higher efficiency, reliability and comfort for many years in Hilton Head Island.
