Swapping snow boots for sunscreen? When you move from Denver to Phoenix, your utility routine changes more than your wardrobe. You trade winter heating for long, intense cooling seasons, and outdoor water use suddenly matters a lot. In this guide, you’ll learn who serves your new home, what to expect with bills, and smart steps to keep costs in check. Let’s dive in.
Phoenix heat vs. Denver cold
Phoenix’s climate is hot and dry with a long cooling season. Average summer highs exceed 100°F, and the city logs many 100°F days most years, which drives air conditioning use and electric bills higher in summer months. Winters are mild, so heating needs are limited compared with Denver. You should plan for higher electricity use from May through September and lower winter heating use overall.
- See the long‑term temperature patterns and cooling degree days for Phoenix Sky Harbor to understand why cooling dominates usage: NOAA climate normals summary.
Bottom line: Expect higher summer electric bills, and relatively modest winter heating needs.
Who powers your home
Two major electric providers serve the Phoenix area. Which one you get depends on your address.
APS vs. SRP
- APS serves large parts of Phoenix and surrounding areas. Verify your address on the APS service area map.
- SRP covers much of central Phoenix and nearby cities. Review SRP’s residential price plans, including their Basic plan, on the SRP price plans page.
Rates and plan options vary by utility and can change. APS has active regulatory updates, so it’s wise to check the APS rate case page before you choose a plan.
Time‑of‑use plans and peak hours
Both utilities offer time‑of‑use plans where energy costs more during late‑afternoon and early‑evening hours. APS, for example, sets on‑peak rates on weekdays from 4 to 7 pm on its TOU plan. Review details here: APS Time‑of‑Use 4–7 pm Weekdays.
Simple habits help you save on TOU plans:
- Run laundry and dishwashers before 4 pm or after 7 pm on weekdays.
- Pre‑cool the home earlier in the day, then coast through the peak.
- Stagger major appliances so they do not run at the same time.
Prep your AC for the desert
Your air conditioner does most of the heavy lifting here. Before move‑in, have a tech inspect and tune it. A smart or programmable thermostat, annual maintenance, clean filters, and ceiling fans all help reduce energy use while keeping you comfortable. See practical guidance from ENERGY STAR on HVAC and thermostats.
Natural gas: smaller role, still important
Southwest Gas serves most Phoenix homes that use natural gas for cooking, water heating, and sometimes space heating. Because winters are mild, many households see lower and more seasonal gas use compared with Denver. Learn about service and recent updates on Southwest Gas in Arizona.
What to do before you buy or lease:
- Confirm whether the home uses gas for heat and hot water.
- Ask the seller or landlord for a full year of gas bills to see winter vs. summer usage.
- Inspect gas appliances and consider efficiency upgrades if they are older.
Water, landscaping, and your bill
In Phoenix, outdoor water use often drives the bill. The City of Phoenix uses a seasonal rate structure. Summer months have higher volume charges, and the city notes that a large share of residential use is outdoors, especially for irrigation and pools. Review current rates and seasonal details on the City of Phoenix water rates page.
Practical steps to reduce water costs:
- Switch to drip irrigation and water in the early morning or evening.
- Replace thirsty turf with drought‑tolerant plants.
- Use a pool cover to limit evaporation.
- Ask the seller for summer and winter water bills to understand the property’s outdoor use.
Phoenix’s water supply includes Colorado River deliveries, local rivers, groundwater, and reclaimed water. The region is managing ongoing Colorado River shortages, which reinforces the importance of conservation. For context on shortage tiers and planning, see CAP’s overview of Colorado River reductions.
City services and internet setup
Most single‑family homes in Phoenix receive city trash and recycling service. Solid‑waste fees are set by the city, and the city implemented a standard 2 percent increase effective January 1, 2025. See current fees on the City of Phoenix solid‑waste rates page.
Internet providers vary by neighborhood. The city’s moving resources list common options, but availability is address specific. Schedule installation early, especially during busy move seasons.
Quick move‑in utility checklist
- Verify your electric provider by address, then select a plan. Start service a few business days before move‑in.
- Start Southwest Gas service if the home uses gas. Confirm any deposit requirements.
- Start City of Phoenix water service and request trash and recycling containers.
- Request 12 months of electric, gas, and water bills from the seller or property manager.
- Inspect and tune your AC. Install a smart thermostat and set schedules.
- Choose a time‑of‑use plan only if your routine fits off‑peak usage.
- Check the irrigation controller, leak test the system, and set seasonal schedules.
- Schedule your internet installation early.
