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

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

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

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

Improved heating and cooling efficiency—Efficiency rankings are calculated on matching unit performance. While installing a lone new unit will improve performance, efficiency will be decreased from what it was envisioned to be. And your savings will not be as much as they’d be with matching units.

Equipment age—If your AC is 10 years old (or older), your heating system is likely just as outdated. Changing both means you’ll have a lot of of years of efficient comfort, regardless of the time of year.

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

It would appear installing just a new cooling system or heating system can feel like a smart decision. But it’s not a very good decision when you factor in decreased efficiency.

Replacing an entire system could be costlier, but you get much higher efficiency, reliability and comfort for many years in Longmont.
