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

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

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

Technology advancements—There have been abundant recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll have these perks all year when you update the complete system.

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

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

New 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 entire system for the same period of time.

On the surface, getting only a new AC or heater may seem like a bargain. But it’s not a great choice when you include lower efficiency.

Installing an entirely new system might cost more, but you get much higher efficiency, reliability and comfort for long into the future in Miami.
