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

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

Coordinated design—Your furnace is created to run with a corresponding air conditioner. This might help improve 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 receive these perks year-round when you update the whole system.

Improved heating and cooling efficiency—Efficiency rankings are calculated on corresponding unit performance. While putting in one new unit will enhance performance, efficiency will be lacking from what it was engineered to be. And your savings will not be as large as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as outdated.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

Updated warranty—A new set of equipment also means you’ll get updated product warranties. You’ll have peace of mind knowing the warranty defends your total system for the same amount of time.

On the surface, installing just a new AC or heater may seem like a good decision. But it’s not a very good choice when you include reduced efficiency.

Replacing an entire system could be more expensive, but you receive much better efficiency, reliability and comfort for long into the future in Gainesville.
