Questions

How long does a central AC condenser last?
Typically 12 to 15 years. CapexClock uses 14 years as its default, and you can change it for your building.
When should I start saving to replace a central AC condenser?
As soon as it's installed. Spreading the cost over its 12–15 year life keeps the replacement from landing as a surprise. The mini calculator on this page shows a monthly amount for yours.
How is a central AC condenser priced in the calculator?
By default it's priced per unit. Enter your own quote or recent invoice; CapexClock never fills in costs for you.
