Our answer is, it’s a good method. Here's why.
Matched design—Your furnace is created to run with a corresponding air conditioner. This may help enhance energy efficiency and performance.
Technology advancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these advantages year-round when you update the full system.
Better heating and cooling efficiency—Efficiency ratings are determined on matching equipment performance. While getting one new unit will improve performance, efficiency will be lacking 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Equipment age—If your AC is 10 years old (or older), your furnace is likely just as outdated. Replacing both means you’ll enjoy lots of years of efficient comfort, no matter the season.
Updated warranty—A new set of equipment also means you’ll get new system warranties. You’ll get peace of mind when you realize the warranty protects your complete system for the same time period.
On the surface, installing just a new cooling system or heating system might seem like a smart decision. But it’s not a very good choice when you factor in decreased efficiency.
Getting an entirely new system could be costlier, but you receive much better efficiency, reliability and comfort for many years in Nashville.
