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

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

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

Technology advancements—There have been abundant recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these perks year-round when you improve both units.

Better heating and cooling efficiency—Efficiency ratings are based on corresponding equipment performance. While installing a single new unit will enhance performance, efficiency will be decreased from what it was designed to be. And your savings will not be as much as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heater is likely just as outdated. Changing both means you’ll have a lot of of years of efficient comfort, whatever the weather.

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

At first glance, getting only a new AC or heating system could feel like a bargain. But it’s not quite a good decision when you consider reduced efficiency.

Getting an entirely new system might be more expensive, but you earn much more efficiency, reliability and comfort for many years in Buffalo.
