Top 5 Energy-Wasting Habits in Murrieta Homes

You open your utility bill. You stare at the total. You wonder how it got so high. You try to turn off the lights when you leave a room. You try to limit your air conditioning use. Yet, the number keeps climbing.

In Murrieta, we face a specific set of energy challenges. We have intense summer heat. We have Time-of-Use (TOU) rates that punish us for using power in the evening. We have homes built in the 1990s and 2000s that are starting to show their age.

The truth is, high bills usually aren’t caused by one major catastrophe. They are caused by small, daily habits that add up. These “energy vampires” drain your wallet silently.

This guide identifies the top five energy-wasting habits we see in local homes. More importantly, it gives you the specific, actionable steps to fix them. You don’t need to rebuild your house to save money. You just need to change how you use it.

Habit #1: The Garage Fridge “Energy Vampire”

Walk into many Murrieta garages, and you will see it. The “beer fridge.” The “overflow fridge.” Usually, it is the old refrigerator from the kitchen that got demoted when you bought a new stainless steel model.

You might think you are saving money by keeping the old one. In reality, this appliance is likely costing you more than the food inside it is worth.

The Problem: Fighting the Heat

Refrigerators work by moving heat. They pull heat out of the insulated box and dump it into the surrounding room. In your kitchen, the room is 72°F. In your garage during a Murrieta July, the room is 105°F.

That old fridge has to work three times as hard to dump heat into a hot garage. The compressor runs 24 hours a day. It never cycles off.

The Cost

An old refrigerator running in a hot garage can consume $200 to $300 in electricity per year. If the door seals are cracked—which is common on older units—that number goes even higher.

The Fix

• The Audit: Go to your garage. Put your hand on the side of the fridge. Is it hot to the touch? Listen to it. Is the motor running constantly?
• The Dollar Bill Test: Close the door on a dollar bill. If you can pull the bill out easily, the seal is bad. You are paying to cool your entire garage.
• The Solution: If you only use it for drinks, consider a smaller, modern beverage cooler. If you must keep it, clean the coils on the back or bottom. Dust acts as insulation. Vacuuming the dust allows the fridge to release heat more efficiently.

Habit #2: Ignoring the “Time-of-Use” (TOU) Clock

In 2026, when you use electricity matters just as much as how much you use. Most Murrieta residents are on Time-of-Use rate plans with Southern California Edison or local providers.

The Problem: The 4 PM to 9 PM Trap

Electricity is most expensive between 4 PM and 9 PM. This is the “On-Peak” window. Rates can be double or triple what they are in the morning.

The habit we see is the “5 PM Routine.” You come home from work. You start the laundry. You load the dishwasher. You turn on the oven for dinner. You crank up the AC because the house feels stuffy.

You are doing all the heavy lifting during the most expensive five hours of the day.

The Fix: Shift Your Load

You don’t have to stop washing clothes. You just have to change the time.

• Delay Start: Almost every modern dishwasher has a “Delay” button. Load it after dinner at 6 PM, but set the delay for 4 or 6 hours. Let it run at midnight when power is cheap.
• Pre-Cooling: Instead of turning the AC on at 5 PM, run it from 1 PM to 3 PM. Cool the house down to 72°F. At 4 PM, turn the thermostat up to 78°F. The house will stay comfortable through the evening without the compressor running during peak rates.
• Laundry Logic: Save heavy loads like towels and bedding for the weekend before 4 PM.

Habit #3: Neglecting the HVAC Air Filter

This is the single most common cause of high energy bills and expensive repairs. We see it every day.

The Problem: Choking Your System

Your air conditioner needs to breathe. It pulls air from your house, runs it over cold coils, and pushes it back out. The filter stands guard to catch dust and pollen.

When the filter gets clogged, the blower motor has to work much harder to pull air through the dirt. This increases energy usage by up to 15%.

Worse, the lack of airflow causes the cold coils to freeze. Ice builds up. The system runs but doesn’t cool. Eventually, the compressor overheats and dies. A $20 filter saves you a $3,000 compressor repair.

The Murrieta Factor

Our area is dusty. We have wind. We have pollen. A filter that lasts three months in San Diego might only last one month in Murrieta.

The Fix

• Check Monthly: Set a recurring reminder on your phone for the first of every month. “Check Air Filter.”
• Don’t Buy the Cheapest: The cheapest fiberglass filters (MERV 1-4) let too much dust through.
• Don’t Buy the Most Expensive: The super-thick “allergy” filters (MERV 13+) can restrict airflow too much for older systems.
• The Sweet Spot: Look for a pleated filter rated MERV 8 to MERV 11. This traps dust without choking the motor.

Habit #4: The “Set It and Forget It” Pool Pump

If you have a pool, you have a second “energy vampire” in your backyard.

The Problem: Over-Pumping

Many homeowners set their pool pump to run for 8 or 10 hours a day because “that’s what the guy said when we built it.”

An older, single-speed pool pump uses a massive amount of power. It is like leaving a hair dryer running for 8 hours straight. It is often the second largest electricity user in the home after the AC.

The Fix: Variable Speed and Timing

• Upgrade: If you still have a single-speed pump, upgrade to a Variable Speed Pump (VSP). A VSP can run at low speed for filtration. It uses 80% less energy than running at high speed. The payback period is often less than two years.
• Optimize the Schedule: You probably don’t need to run the pump for 10 hours in the winter. Cut it back to 4 or 6 hours.
• Run at Night: Schedule the pump to run during off-peak hours (after 9 PM or before 4 PM). Do not let it run during the 4-9 PM expensive window.

Habit #5: Leaky Ducts in the Attic

You pay good money to cool the air in your house. Why are you sending 20% of it into your attic?

The Problem: The Hidden Leak

Many homes in Murrieta were built in the late 1990s and early 2000s. The ductwork in the attic is flexible plastic tubing. Over time, the tape dries out. The connections come loose. Rats might chew holes in the plastic.

You turn on the AC. The unit produces cold air. But before that air reaches your bedroom, 20% to 30% of it leaks out into the attic. You are essentially trying to air condition the neighborhood.

The Cost

If you lose 20% of your air, your system has to run 20% longer to cool the house. That is a direct 20% tax on your cooling bill.

The Fix

• The Inspection: Go into the attic (early in the morning when it’s cool). Turn on the fan. Feel around the connections where the ducts meet the vents. Do you feel air blowing?
• The Seal: Professional sealing is best, but you can do minor repairs with “mastic” sealant (a gooey paste that hardens) or high-quality foil tape. Do not use “duct tape.” Ironically, standard duct tape fails quickly in the heat of an attic.

Bonus: The “Phantom Load” of Smart Devices

We love our gadgets. But they consume power even when they are “off.”

The Problem: Instant-On

Your TV is never truly off. It is waiting for a signal from the remote. Your game console is waiting for an update. Your smart speakers are listening for their wake word.

These devices draw a small amount of power 24/7. This is called “phantom load” or “vampire power.” In a house with 20 or 30 devices, this can add up to 5-10% of your total bill.

The Fix

• Smart Power Strips: Use power strips for your entertainment center and home office. Smart strips have a “control” outlet. When you turn off the TV (the control), the strip automatically cuts power to the game console, soundbar, and DVD player.
• Unplug: If you have a guest room TV that is rarely used, unplug it. Unplug phone chargers when they aren’t charging a phone.

Saving energy in Murrieta isn’t about sitting in the dark or sweating through the summer. It is about being smarter than the meter.

Fix the garage fridge. Change the filter. Run the dishwasher at night. These small changes keep money in your pocket instead of sending it to the utility company.
