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

Our answer is, it’s a wise idea. Here's why.

Coordinated design—Your furnace. This may help better energy efficiency and performance.

Technology advancements—There have been many recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these perks all year when you update the whole system.

Better heating and cooling efficiency—Efficiency levels are based on corresponding equipment performance. While adding one new unit will enhance performance, efficiency will be lacking from what it was envisioned to be. And your savings will not be as big as they’d be with matching units.

Equipment age—If your cooling system is 10 years old (or older), your heater is likely just as outdated. Switching both means you’ll enjoy many years of efficient comfort, regardless of the time of year.

Updated warranty—A new set of equipment also means you’ll receive valid product warranties. You’ll have peace of mind knowing the warranty protects your entire system for the same amount of time.

On the surface, getting only a new air conditioner or furnace could seem like a good decision. But it’s not a very good bargain when you include decreased efficiency.

Replacing an entire system might cost more, but you earn much better efficiency, reliability and comfort for years to come in Houston.
