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

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

Paired design—Your furnace is created to run with a matching air conditioner. This can help better energy efficiency and performance.

Technology advancements—There have been abundant recent improvements in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll receive these advantages throughout the year when you update the whole system.

Higher heating and cooling efficiency—Efficiency ratings are calculated on matching equipment performance. While installing a single new unit will enhance performance, efficiency will be decreased 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 old. Replacing both means you’ll enjoy a lot of of years of efficient comfort, whatever the season.

Up-to-date warranty—A new set of equipment also means you’ll get valid equipment warranties. You’ll get peace of mind when you know the warranty protects your complete system for the same amount of time.

It would appear installing just a new cooling system or heating system might feel like a good decision. But it’s not a very good choice when you include reduced efficiency.

Installing an entirely new system may be costlier, but you get much higher efficiency, reliability and comfort for long into the future in Mobile.
