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

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

Matched design—Your furnace is created to run with a matching air conditioner. This might help enhance energy efficiency and performance.

Technology enhancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll have these benefits throughout the year when you update the complete system.

Improved heating and cooling efficiency—Efficiency levels are determined on matched system performance. While getting a single new unit will result in better performance, efficiency will be lower from what it was engineered to be. And your savings will not be as big as they’d be with matching equipment.

Equipment age—If your air conditioner is 10 years old (or older), your heating system is likely just as old. Changing both means you’ll receive lots of years of efficient comfort, regardless of the weather.

New warranty—A new set of units also means you’ll get new equipment warranties. You’ll have peace of mind when you realize the warranty covers your whole system for the same amount of time.

At first glance, getting only a new cooling system or furnace may seem like a bargain. But it’s not quite a good bargain when you factor in reduced efficiency.

Replacing an entire system could be more expensive, but you receive much better efficiency, reliability and comfort for many years in Denver.
