Frequently asked questions

Repair or replace?

Replace when repair exceeds a third of new cost, the unit is past two-thirds of lifespan, and the efficient model saves 20 percent or more.

How is payback figured?

Price premium of the efficient model divided by annual energy savings. Under 3 years is compelling.

What counts as annual savings?

Watt difference times yearly hours divided by 1,000 times your rate, plus avoided bulbs, filters, or water.

Does usage change the answer?

Completely. Efficient upgrades pay in busy households and lose in guest rooms used monthly.
