LADWP Rush Hour Rewards: Get Paid to Save

LADWP’s Rush Hour Rewards program is a free enrollment that pays you for helping reduce grid demand during peak summer afternoons (typically 4–9 PM on hot days):

• Enrollment bonus: $85–$100 one-time payment for qualifying thermostat
• Annual bill credits: $20–$50 per summer season for allowing thermostat adjustments
• How it works: LADWP may raise your set point 1–4°F for 2–4 hours during peak events (typically 8–15 events per year)
• You can opt out of any individual event with one tap in the app
• Compatible devices: Ecobee, Nest, Honeywell, Emerson Sensi, and others

C-Wire: Do You Have One?

Check your current thermostat wiring before buying. Remove the thermostat cover and look at the wire terminals:

• 5 or more wires present → You almost certainly have a C-wire. Any smart thermostat will work
• 4 wires (R, Y, G, W) → Probably no C-wire. Buy a thermostat with a power adapter (Nest includes one; Ecobee includes a PEK adapter)
• 2 wires only → Professional installation needed, or choose Ecobee with PEK adapter
• Unsure → Call Upright HVAC — we check for free during any service call

Frequently Asked Questions

What is the best smart thermostat for a Los Angeles home?

The Ecobee SmartThermostat Premium and Nest Learning Thermostat (4th gen) are the top picks for LA homes. Both integrate with LADWP’s Rush Hour Rewards program for additional rebates. Ecobee has a slight edge for homes with uneven temperatures (it includes a remote room sensor). Nest is simpler to use.

Does LADWP offer rebates for smart thermostats?

Yes. LADWP’s Rush Hour Rewards program pays $85–$100 for enrolling a qualifying smart thermostat. You also get bill credits when you allow LADWP to slightly adjust your thermostat (1–4°F) during peak demand periods. Ecobee and Nest both support this program.

Will a smart thermostat save money in Los Angeles?

Yes. Smart thermostats save an average of 10–15% on cooling costs by learning your schedule and pre-cooling before peak LADWP rate periods. In LA, where you might run AC 5–6 months per year, that’s $80–$200 per year depending on your home size and LADWP tier.

Can I install a smart thermostat myself?

Most homeowners can install a smart thermostat in 30–60 minutes with basic tools. The main risk is incorrect C-wire connection — most modern HVAC systems have a common wire (C-wire) for smart thermostat power, but some older LA homes don’t. If your current thermostat has only 2 wires, you’ll need a professional install or a thermostat with a built-in power adapter.

What is a C-wire and do I need one for a smart thermostat?

A C-wire (common wire) provides constant 24V power to a smart thermostat so it can connect to WiFi and run its display. Most homes built or HVAC-updated after 2000 have a C-wire. Homes with only 2-wire thermostats need either a C-wire adapter kit (like Nest’s, usually included) or a professional to run a new wire.
