The reality of LA electricity bills
LA electricity bills have climbed every year for the past decade. LADWP rates are now well above the national average, and the summer bills can be brutal. Most homeowners are paying 20-40% more than they should for reasons that are easy to fix.
What actually moves the needle
1. AC: the single biggest line item
In most LA homes, air conditioning accounts for 40-60% of summer electricity use. The fix is not to use less AC. It is to use it more efficiently.
The changes that matter:
- Set the thermostat to 78F when you are home, 85F when you are out. Each degree below 78 adds about 6-8% to your cooling cost.
- Use a smart thermostat (Nest, Ecobee, or similar). Saves 10-15% on cooling without changing comfort.
- Service the AC annually. A clean filter and a charged system can cut 10-20% off the cooling bill.
- Seal the ducts. Leaky ducts in the attic can lose 20-30% of the cooled air before it reaches the rooms. Duct sealing is one of the highest-ROI energy upgrades.
2. The pool pump: the silent bill killer
If your pool pump runs 8+ hours a day at full speed, it is one of the top 3 energy users in your home. A variable-speed pump cuts pump energy use by 50-80%.
The cost to upgrade is 00-,500 for the pump, plus install. Most LA pool owners recover the cost in 1-2 years through lower electricity bills.
3. The water heater: a 24/7 energy user
Water heating is the second-largest energy user in most homes, after AC. Options that actually save money:
- Heat pump water heater: uses 60-70% less electricity than a standard electric water heater. Federal tax credits (IRA 25C) cover 30% of the cost up to ,000.
- Lower the thermostat. Most water heaters are set to 130-140F. Dropping to 120F is safe for most households and saves 5-10% on water heating.
- Insulate the first 6 feet of pipe from the water heater. Cheap and effective.
4. Lighting: easier than you think
Most LA homes still have a mix of old bulbs. The math:
- A 60W incandescent costs about per year in electricity
- An equivalent LED costs about per year
- For a home with 40 bulbs, that is 80 per year in lighting alone
Replacing every bulb in the home with LED costs about 0-0 in bulbs. The payback is 2-3 months. After that, every month is savings.
5. The phantom load
Many electronics draw power even when off - TVs, game consoles, computers, chargers, coffee makers with clocks. This phantom load can be 5-10% of a home's electricity bill.
The fix: smart power strips. They cut power to peripherals when the main device is off. 0-0 per setup, depending on how many devices.
What does NOT move the needle
- Turning off lights when you leave the room. Real but small. Maybe 1-2% of the bill.
- Running the dishwasher only when full. Real but small. Maybe 0.5% of the bill.
- Lowering the water heater temperature from 140F to 120F. Real, but smaller than the heat-pump upgrade.
- Switching to a time-of-use rate plan without changing behavior. The rate plan only helps if you shift usage to off-peak hours.
The high-ROI upgrades (in order)
1. LED bulbs throughout the home. Cost: 0-0. Savings: 00-00/yr. Payback: 2-3 months. 2. Smart thermostat. Cost: 50-00. Savings: 50-00/yr. Payback: 1-2 years. 3. Duct sealing. Cost: 00-,500. Savings: 00-00/yr. Payback: 1-3 years. 4. Heat pump water heater. Cost: ,500-,000 after credits. Savings: 00-00/yr. Payback: 3-6 years. 5. Variable-speed pool pump. Cost: ,000-,000. Savings: 00-00/yr. Payback: 1-3 years. 6. Solar panels. Cost: 5,000-5,000 after credits. Savings: ,500-,000/yr. Payback: 5-10 years.
How to read your LADWP bill
LADWP bills are confusing. The actual structure:
- Tier 1: the first ~500 kWh per month, at the lowest rate
- Tier 2: the next ~500 kWh, at a higher rate
- Tier 3: anything above 1,000 kWh, at the highest rate
- Delivery charges: fixed monthly fee plus per-kWh charge
- Taxes and surcharges: various small line items
Most LA homes that complain about their bills are in Tier 2 or Tier 3 during summer. The fix is to reduce peak usage (AC) enough to stay in Tier 1 or low Tier 2.
Time-of-use plans
LADWP offers time-of-use (TOU) plans where electricity is cheaper at night and more expensive during peak hours (4-9 PM). For most LA homes, TOU saves money if you can shift:
- Dishwasher and laundry to off-peak
- Pool pump to off-peak (often already runs at night)
- AC pre-cooling to before 4 PM
If your usage is mostly during peak hours (working from home, kids home during the day), TOU may cost more, not less. Run the numbers on your actual bill before switching.
When to call an electrician
Most of the savings above do not require an electrician. The ones that do:
- Duct sealing (need a specialist)
- Heat pump water heater install (electrical work + plumbing)
- Variable-speed pool pump (electrical work)
- Solar panel install (licensed solar installer)
A good electrician can also do an energy audit of your home to identify the biggest savings opportunities specific to your house.
Ready to lower your bill?
Start with the LED bulbs and the smart thermostat. They pay for themselves in months. Then look at the bigger upgrades (duct sealing, water heater, pool pump) based on what your bill actually shows.
If you want a professional to walk your home and identify the highest-ROI upgrades, we do energy audits in the LA area. The audit pays for itself in savings, usually within the first quarter.
Call (818) 391-8797 to schedule an energy audit. We will tell you honestly what is worth doing and what is not.
*Want a straight answer on what will actually save you money? We will tell you after the audit.*
