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

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

Coordinated design—Your furnace is made to function with a paired air conditioner. This can help better energy efficiency and performance.

Technology enhancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these benefits year-round when you update both units.

Improved heating and cooling efficiency—Efficiency ratings are calculated on matching unit performance. While installing 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 large as they’d be with matching units.

Equipment age—If your air conditioner is 10 years old (or older), your heater is likely just as dated. Replacing both means you’ll have lots of years of efficient comfort, whatever the season.

Updated warranty—A new system also means you’ll have valid system warranties. You’ll receive peace of mind when you realize the warranty defends your complete system for the same amount of time.

At first glance, installing just a new cooling system or heater can appear to be a good decision. But it’s not a great choice when you factor in reduced efficiency.

Installing an entirely new system could be more expensive, but you receive much better efficiency, reliability and comfort for many years in Fort Worth.
