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

Our answer is, it’s a good idea. Here's why.

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

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

Better heating and cooling efficiency—Efficiency rankings are determined on matching unit performance. While installing a lone 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 big as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as old. Changing both means you’ll enjoy lots of years of efficient comfort, no matter the time of year.

Up-to-date warranty—A new set of units also means you’ll have new equipment warranties. You’ll have peace of mind when you realize the warranty covers your complete system for the same time period.

At first glance, installing just a new cooling system or furnace could appear to be a good decision. But it’s not quite a good choice when you factor in decreased efficiency.

Getting an entirely new system may be costlier, but you get much higher efficiency, reliability and comfort for years to come in Fort Myers.
