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

Our reply is, it’s a good method. Here's why.

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

Technology advancements—There have been abundant recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these advantages all year when you upgrade the full system.

Improved heating and cooling efficiency—Efficiency ratings are formed on matched system performance. While adding a single new unit will enhance performance, efficiency will be lower 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Equipment age—If your cooling system is 10 years old (or older), your heater is likely just as outdated. Switching both means you’ll receive lots of years of efficient comfort, whatever the time of year.

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

On the surface, installing just a new air conditioner or furnace could seem like a smart decision. But it’s not quite a good bargain when you include lower efficiency.

Getting an entirely new system might cost more, but you receive much better efficiency, reliability and comfort for long into the future in Kansas City.
