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

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

Paired design—Your furnace is made to run with a paired air conditioner. This might help enhance energy efficiency and performance.

Technology enhancements—There have been a lot of recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these perks year-round when you update the complete system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matching unit performance. While putting in a single new unit will improve performance, efficiency will be lacking from what it was designed to be. And your savings will not be as big 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 enjoy a lot of of years of efficient comfort, no matter the weather.

Updated warranty—A new system also means you’ll receive new system warranties. You’ll receive peace of mind when you realize the warranty protects your entire system for the same time period.

On the surface, installing just a new AC or heater can seem like a good decision. But it’s not a great choice when you factor in reduced efficiency.

Getting an entirely new system may be costlier, but you earn much more efficiency, reliability and comfort for many years in Boise.
