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

Our response is, it’s a good method. Here's why.

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

Technology upgrades—There have been a lot of recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll receive these benefits throughout the year when you update the whole system.

Better heating and cooling efficiency—Efficiency levels are determined on corresponding equipment performance. While putting in a lone new unit will improve performance, efficiency will be lower from what it was envisioned to be. And your savings will not be as much as they’d be with a matched system.

Equipment age—If your cooling system is 10 years old (or older), your heater is likely just as old. Changing both means you’ll have a lot of of years of efficient comfort, no matter the season.

Updated warranty—A new set of equipment also means you’ll receive valid product warranties. You’ll have peace of mind when you realize the warranty covers your whole system for the same period of time.

On the surface, installing just a new cooling system or furnace may feel like a good decision. But it’s not quite a good decision when you consider reduced efficiency.

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