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 function with a matching air conditioner. This can help improve energy efficiency and performance.

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

Improved heating and cooling efficiency—Efficiency ratings are determined on corresponding unit performance. While getting a single new unit will enhance performance, efficiency will be lacking from what it was envisioned to be. And your savings will not be as large as they’d be with matching equipment.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as outdated.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.

New warranty—A new set of equipment 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, getting only a new air conditioner or heating system could appear to be a bargain. But it’s not a very good choice when you include reduced efficiency.

Replacing an entire system could be costlier, but you earn much more efficiency, reliability and comfort for long into the future in La Porte.
