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

Our response is, it’s a good idea. Here's why.

Matched design—Your furnace is made to work with a corresponding air conditioner. This may help enhance 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 advantages throughout the year when you improve the complete system.

Better heating and cooling efficiency—Efficiency levels are formed on corresponding system performance. While installing a lone new unit will result in better performance, efficiency will be lower from what it was envisioned 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Equipment age—If your air conditioner is 10 years old (or older), your heating system is likely just as outdated. Replacing both means you’ll enjoy lots of years of efficient comfort, regardless of the time of year.

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

At first glance, getting only a new AC or heating system may seem like a bargain. But it’s not a great decision when you factor in reduced efficiency.

Getting an entirely new system might cost more, but you get much better efficiency, reliability and comfort for many years in Miami.
