Cutting the number down
- The second fridge in the garage is often the most expensive appliance in a house, because it is usually the oldest one and it works against garage heat.
- Coils packed with dust make the compressor run longer for the same cooling. Vacuuming them takes minutes.
- A door gasket that no longer grips a dollar bill is leaking cold around the clock.
