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

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

Paired design—Your furnace is made to work with a corresponding air conditioner. This may help improve energy efficiency and performance.

Technology advancements—There have been a lot of recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these advantages all year when you update the whole system.

Higher heating and cooling efficiency—Efficiency levels are based on matched unit performance. While getting 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 big as they’d be with a matched system.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as outdated. Changing both means you’ll have lots of years of efficient comfort, no matter the season.

New warranty—A new set of units also means you’ll receive updated 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 cooling system or furnace may appear to be a smart decision. But it’s not quite a good choice when you factor in lower efficiency.

Installing an entirely new system could cost more, but you receive much higher efficiency, reliability and comfort for long into the future in Birmingham.
