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

Our reply is, it’s a wise idea. Here's why.

Matched design—Your furnace is created to function with a corresponding air conditioner. This can help improve energy efficiency and performance.

Technology enhancements—There have been abundant recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll receive these perks throughout the year when you update the full system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matched equipment performance. While installing a lone new unit will result in better performance, efficiency will be lacking from what it was designed to be. And your savings will not be as large as they’d be with matching units.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as outdated. Switching both means you’ll receive a lot of of years of efficient comfort, no matter the weather.

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

On the surface, replacing only your cooling system or heating system may appear to be a smart decision. But it’s not a very good bargain when you factor in reduced efficiency.

Installing an entirely new system could be more expensive, but you earn much more efficiency, reliability and comfort for years to come in Tempe.
