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

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

Paired design—Your furnace is designed to work with a corresponding 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 heating and cooling. You’ll receive these benefits throughout the year when you update the whole system.

Higher heating and cooling efficiency—Efficiency rankings are calculated on corresponding equipment performance. While adding one new unit will improve performance, efficiency will be lacking from what it was envisioned to be. And your savings will not be as big as they’d be with matching units.

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

Updated warranty—A new set of equipment also means you’ll get valid system warranties. You’ll have peace of mind when you know the warranty defends your complete system for the same period of time.

It would appear replacing only your cooling system or heater may seem like a smart decision. But it’s not quite a good choice when you consider reduced efficiency.

Installing an entirely new system may be more expensive, but you receive much more efficiency, reliability and comfort for long into the future in Rochester.
