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

Our answer is, it’s a good approach. Here's why.

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

Technology enhancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll receive these advantages all year when you improve both units.

Improved heating and cooling efficiency—Efficiency rankings are based on matched unit performance. While putting in a single 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 a matched system.

Equipment age—If your cooling system is 10 years old (or older), your heating system is likely just as outdated. Replacing both means you’ll receive many years of efficient comfort, no matter the season.

Up-to-date warranty—A new set of equipment also means you’ll receive up-to-date product warranties. You’ll receive peace of mind knowing the warranty covers your entire system for the same period of time.

At first glance, getting only a new AC or heater might seem like a good decision. But it’s not quite a good decision when you factor in lower efficiency.

Installing an entirely new system might cost more, but you receive much more efficiency, reliability and comfort for years to come in Hillsborough.
