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

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

Matched design—Your furnace is made to work with a matching air conditioner. This might help better energy efficiency and performance.

Technology upgrades—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll receive these advantages year-round when you upgrade both units.

Better heating and cooling efficiency—Efficiency rankings are based on matching system performance. While installing one new unit will result in better performance, efficiency will be lower from what it was engineered to be. And your savings will not be as much as they’d be with matching equipment.

Equipment age—If your air conditioner is 10 years old (or older), your heating system is likely just as old. Switching both means you’ll enjoy a lot of of years of efficient comfort, no matter the time of year.

Up-to-date warranty—A new set of equipment also means you’ll get up-to-date equipment warranties. You’ll receive peace of mind when you know the warranty defends your whole system for the same period of time.

At first glance, installing just a new air conditioner or heater might feel like a smart decision. But it’s not a very good choice when you consider decreased efficiency.

Installing an entirely new system could be more expensive, but you get much more efficiency, reliability and comfort for many years in Kingston.
