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

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

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

Technology enhancements—There have been a lot of recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll receive these advantages year-round when you improve both units.

Higher heating and cooling efficiency—Efficiency ratings are formed on matching system performance. While putting in a lone new unit will improve performance, efficiency will be lacking from what it was designed to be. And your savings will not be as big as they’d be with matching equipment.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as old. Replacing both means you’ll have many years of efficient comfort, regardless of the weather.

Up-to-date warranty—A new system also means you’ll have valid system 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, replacing only your AC or heating system may appear to be a smart decision. But it’s not quite a good bargain when you consider lower efficiency.

Replacing an entire system might cost more, but you get much more efficiency, reliability and comfort for years to come in Pierre.
