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

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

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

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

Higher heating and cooling efficiency—Efficiency ratings are calculated on matched equipment performance. While adding one new unit will improve performance, efficiency will be lower from what it was designed 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Equipment age—If your AC is 10 years old (or older), your furnace is likely just as outdated.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 weather.

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

On the surface, getting only a new cooling system or heater could appear to be a smart decision. But it’s not a great decision when you factor in lower efficiency.

Installing an entirely new system may be costlier, but you get much better efficiency, reliability and comfort for long into the future in Dayton.
