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

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

Coordinated design—Your furnace. This may help better energy efficiency and performance.

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

Better heating and cooling efficiency—Efficiency ratings are determined on matching equipment performance. While putting in a single new unit will enhance performance, efficiency will be lacking from what it was envisioned to be. And your savings will not be as large as they’d be with matching equipment.

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

New warranty—A new system also means you’ll have up-to-date product warranties. You’ll get peace of mind when you realize the warranty protects your entire system for the same time period.

At first glance, replacing only your cooling system or furnace could seem like a smart decision. But it’s not quite a good decision when you include lower efficiency.

Getting an entirely new system could cost more, but you get much higher efficiency, reliability and comfort for long into the future in Richmond.
