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

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

Paired design—Your furnace is made to run with a corresponding air conditioner. This may help better energy efficiency and performance.

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

Better heating and cooling efficiency—Efficiency ratings are determined on matching equipment performance. While putting in a single new unit will result in better 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 heating system is likely just as dated. Replacing both means you’ll have lots of years of efficient comfort, regardless of the season.

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

On the surface, replacing only your cooling system or furnace may feel like a smart decision. But it’s not quite a good choice when you factor in lower efficiency.

Getting an entirely new system could cost more, but you get much better efficiency, reliability and comfort for many years in Richmond.
