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

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

Matched design—Your furnace is designed to run with a paired air conditioner. This may help enhance energy efficiency and performance.

Technology enhancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these advantages all year when you improve the full system.

Higher heating and cooling efficiency—Efficiency levels are formed on matched system performance. While installing one new unit will improve performance, efficiency will be decreased from what it was designed to be. And your savings will not be as much as they’d be with matching equipment.

Equipment age—If your AC is 10 years old (or older), your furnace is likely just as dated. Changing both means you’ll receive a lot of of years of efficient comfort, whatever the season.

New warranty—A new system also means you’ll receive new equipment warranties. You’ll get peace of mind when you know the warranty covers your whole system for the same period of time.

On the surface, installing just a new cooling system or heater may seem like a smart decision. But it’s not quite a good choice when you factor in reduced efficiency.

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