Why Is My Electric Bill So High? Start Here

Nobody's electric bill jumps for no reason. When the number climbs, something in your house is eating power, and it is almost always one of seven things. Here is how to find them and what to do about each one.

1. The water heater is the usual suspect

Your water heater is one of the biggest electric loads in the house, and most people never touch it. If yours is set above 120 degrees, you are paying to keep water hotter than you need. Turn it down to 120. You will not notice the difference in the shower, but your bill will notice. An old electric tank with heavy sediment buildup also works harder than it should. If you have never flushed it, that is a weekend job worth doing.

2. The HVAC system is working too hard

A dirty furnace filter makes your blower run longer to push the same air. A thermostat set two degrees lower in winter saves real money over a month. And if your outdoor unit is packed with leaves or the indoor coil is dirty, the whole system loses efficiency. Change the filter, give the thermostat a sane schedule, and keep the equipment clean. Boring advice, but it is boring because it works.

3. The old fridge in the garage

That second fridge in the garage or basement is a classic bill killer. Old refrigerators can use three times the power of a modern one, and a garage fridge in summer heat works overtime. If you barely use it, unplug it. If you need it, at least make sure the coils are clean and the door seals tight. A dollar bill shut in the door should be hard to pull out. If it slides free, the seal is shot and cold air is leaking out around the clock.

4. Space heaters

A single 1,500-watt space heater running eight hours a day can add serious money to your monthly bill. People run them because one room is cold, but the real problem is usually bad insulation, leaky windows, or a blocked vent in that room. Fix the room and you can retire the heater. If you must use one, only heat the room you are in and turn it off when you leave.

5. Vampire loads

TVs, game consoles, cable boxes, and chargers draw power even when they are off. One device is nothing. Twenty of them add up. Put entertainment setups on a power strip and switch it off at night. Unplug chargers that are not charging anything. It will not cut your bill in half, but it trims the waste for free.

6. The dryer

Electric dryers are power hungry, and a clogged vent makes them run twice as long. If your clothes need two cycles, the vent is almost certainly restricted. Clean the lint trap every load and clean the full vent run at least once a year. Shorter dry times mean real savings, and it is also a fire safety issue.

7. The well pump or pool pump

If you are on a well, a short-cycling pump or a waterlogged pressure tank can run far more than it should. Listen for the pump kicking on and off constantly. For pools, running the pump 24 hours a day is overkill for most setups. Eight to twelve hours is usually plenty. A timer pays for itself fast.

How to actually find your hogs

Start with the bill itself. Most utilities show daily usage now. Look for the day it jumped and think about what changed. Then walk the house with this list. Check the water heater setting, change the HVAC filter, feel for hot chargers and warm power bricks, and look at what runs all day. You will usually find the culprit in one walkthrough.
