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

Our response is, it’s a smart idea. Here's why.

Matched design—Your furnace is designed to function with a paired air conditioner. This might help improve 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 have these perks all year when you update the full system.

Better heating and cooling efficiency—Efficiency ratings are based on matching unit performance. While adding a single new unit will result in better performance, efficiency will be lower from what it was designed 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Equipment age—If your AC is 10 years old (or older), your heater is likely just as outdated. Changing both means you’ll enjoy a lot of of years of efficient comfort, regardless of the season.

Updated warranty—A new set of equipment also means you’ll get new equipment warranties. You’ll get peace of mind knowing the warranty protects your total system for the same amount of time.

At first glance, replacing only your cooling system or heating system could feel like a good decision. But it’s not a very good decision when you factor in lower efficiency.

Installing an entirely new system may be more expensive, but you earn much better efficiency, reliability and comfort for long into the future in Livermore.
