Our response is, it’s a great idea. Here's why.
Matched design—Your furnace is designed to work with a paired air conditioner. This may help better energy efficiency and performance.
Technology upgrades—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll receive these advantages all year when you upgrade the whole system.
Improved heating and cooling efficiency—Efficiency ratings are formed on matching equipment performance. While installing a single new unit will enhance performance, efficiency will be decreased from what it was designed 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 furnace is likely just as dated. Changing both means you’ll have many years of efficient comfort, no matter the weather.
New warranty—A new system also means you’ll get valid equipment warranties. You’ll get peace of mind knowing the warranty protects your whole system for the same amount of time.
It would appear getting only a new air conditioner or heater might feel like a bargain. But it’s not a very good decision when you consider reduced efficiency.
Getting an entirely new system might be more expensive, but you earn much better efficiency, reliability and comfort for long into the future in Atlanta.
