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

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

Coordinated design—Your furnace. This might help enhance energy efficiency and performance.

Technology upgrades—There have been a lot of recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these benefits year-round when you update the full system.

Higher heating and cooling efficiency—Efficiency levels are formed on matching unit performance. While installing one 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 large as they’d be with a matched system.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as dated. Switching both means you’ll have lots of years of efficient comfort, no matter the time of year.

New warranty—A new set of equipment also means you’ll get valid equipment warranties. You’ll receive peace of mind knowing the warranty defends your entire system for the same time period.

On the surface, replacing only your AC or furnace can seem like a bargain. But it’s not quite a good bargain when you factor in lower efficiency.

Installing an entirely new system may cost more, but you earn much better efficiency, reliability and comfort for many years in Medina.
