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 made to run with a paired air conditioner. This may help enhance energy efficiency and performance.

Technology enhancements—There have been a lot of recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these advantages all year when you update the full system.

Improved heating and cooling efficiency—Efficiency levels are calculated on corresponding 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Equipment age—If your AC is 10 years old (or older), your heating system is likely just as outdated. Switching both means you’ll have a lot of of years of efficient comfort, no matter the weather.

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

It would appear getting only a new cooling system or heating system can feel like a good decision. But it’s not a very good choice 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.
