Energy-Saving Tips: How Your Appliances Can Lower Your Utility Bills

Refrigerators: The Biggest Year-Round Draw

Because it runs constantly, the fridge is usually the single largest continuous energy user in the kitchen. Keep condenser coils clean (dust forces the compressor to work harder), avoid setting the temperature colder than necessary — 37–40°F for the fridge and 0–5°F for the freezer is plenty — and check door seals periodically, since even a small gap forces continuous, wasted cooling effort.

Dryers: Where Small Habits Add Up Fast

Clean the lint trap every load — a clogged trap makes the dryer work harder and longer for the same result. Dry consecutive loads back-to-back while the dryer is still warm rather than letting it fully cool between each one, and consider a lower heat setting for items that don’t need full heat, like delicates, which finish just as effectively at meaningfully lower energy cost.

Dishwashers: Skip the Heated Dry Setting

The heated dry cycle is one of the most energy-intensive settings on a dishwasher and often unnecessary — most modern dishwashers dry effectively with the door cracked open after the wash cycle ends, using no additional energy at all. Also run full loads rather than half-empty ones; a dishwasher uses roughly the same energy regardless of load size.

Ovens: Avoid Peeking and Preheat Only When Needed

Opening the oven door during baking lets out a significant amount of accumulated heat, forcing the element to work harder to recover — use the oven light and window instead of opening the door to check. And skip preheating for dishes that cook over 45 minutes or more, where the brief preheat period barely affects the final result.

Washers: Cold Water Does More Than People Think

Modern detergents are formulated to work effectively in cold water, and heating water accounts for a significant share of a washer’s total energy use. Switching most loads to cold — reserving hot only for genuinely soiled items or specific fabric needs — is one of the simplest, highest-impact changes available.

Microwaves: Underrated for Efficiency

For reheating and smaller cooking tasks, a microwave uses meaningfully less energy than an oven, both because it heats food directly rather than heating a whole cavity first, and because cook times are shorter. Worth defaulting to for anything it can reasonably handle instead of firing up a full oven.

The Maintenance Connection

Nearly every energy-saving tip above overlaps directly with basic maintenance — a well-sealed, well-maintained appliance is inherently a more efficient one. Skipping maintenance doesn’t just risk a future repair, it costs you in the utility bill every single month in the meantime.

What Actually Moves the Needle vs. What Doesn’t

Coil cleaning, door seals, and avoiding heated dry and unnecessary preheat are genuinely high-impact changes. Smaller things like unplugging rarely-used small appliances help marginally but won’t meaningfully affect a bill the way the appliance-specific habits above do — worth focusing effort where it actually counts.

When an Appliance Itself Is the Problem

If you’ve adopted these habits and your bill still seems high, a failing seal, a dirty coil you can’t fully access, or a fan working harder than it should to compensate for another issue may be at play — worth having a technician check rather than assuming the appliance is simply old and inefficient.

A Simple Way to Track Whether Changes Are Working

Pick one or two changes from this guide, note your utility bill for the following one or two billing cycles, and compare against the same period the prior year if possible to account for seasonal variation. This gives you a genuine before-and-after comparison rather than guessing whether a change actually helped.

Seasonal Considerations Worth Knowing

Refrigerator coils tend to accumulate dust faster in homes with forced-air heating running through winter, making a fall cleaning particularly worthwhile before the heating season puts extra demand on the system. Summer, meanwhile, is when a struggling door seal shows its energy cost most clearly, as the fridge fights harder against a bigger indoor-outdoor temperature gap.
