Opening an Arizona home for winter comes down to five jobs: restart utilities, test the air conditioning and water heater, check every plumbing fixture, look for pests, and renew community and mail settings. Book vendors before you fly in, then walk the house slowly on day one with a written checklist in hand.

Start with your house book

The easiest reopen starts the spring before. I suggest a one-page "house book" kept in a drawer and on your phone, with:

  • Utility account numbers and the provider contact for each service
  • HOA or recreation center portal login and card numbers
  • Your HVAC, plumbing, pest and pool vendors
  • Alarm and camera monitoring contacts
  • Photos showing the water shutoff, gas shutoff and electric panel

Update it every time you close the house so fall becomes a checklist rather than a memory test.

Utilities and service restarts

Call or log in to each provider before you arrive if you stopped or changed service for summer: electric, water, gas, trash, internet and propane if you have it. APS lets customers start, stop or move service through its online account tools, and other Valley utilities and city water departments run their own processes, so check each provider's official site. Do not assume a summer setting reverses on its own.

If you use a smart thermostat, confirm it is online and the schedule is right. A dropped Wi-Fi connection can leave the house warmer than expected on arrival week.

Air conditioning and water heater

Arizona summers are hard on cooling equipment, even in an empty house. Before or right after you arrive:

  • Schedule a tune-up and filter change with a licensed HVAC contractor (the Arizona Registrar of Contractors at roc.az.gov lets you check a license)
  • Listen for unusual noises on the first cool-down and note any warm rooms
  • Make sure the condensate drain line is clear
  • Follow the manufacturer's restart steps for your water heater and look for moisture or rust at the base

If the thermostat sat at a high setting all summer, give the system a day to bring temperature and humidity down before you judge it.

Plumbing and leak checks

On day one, check every sink, toilet, shower, the water heater pan, the washer box and any visible supply line. Run water in rarely used fixtures to refill traps. If you have a softener or filtration system, follow the manufacturer's restart steps. Smart leak sensors and the water meter can show whether anything ran while you were away.

If you shut off and drained the water, turn it back on slowly and watch fittings that may have dried out. When something looks wrong, call a licensed plumber before leaving the house overnight.

Scorpions, pests and entry points

A quiet house invites pests. University of Arizona Cooperative Extension guidance on scorpions focuses on taking away hiding places and sealing entry points. On reopen day, walk the outside and look at:

  • Weatherstripping on loose doors and windows, plus door sweeps and garage side doors
  • Weep holes in brick veneer, gaps at eaves and around pipes that need caulk
  • Torn or loose window screens
  • Debris, boards, stacked items and low ground cover near the walls
  • Tree branches and shrubs touching the house or roof

If you use a pest control company, time any interior service around your arrival so kitchens and bedrooms are ready when you need them.

Pool, spa and yard

If you have a pool or spa, contact your pool company before you arrive so water chemistry and equipment are ready. Check pump and timer schedules, salt cell or chlorinator settings, the safety cover, and supply lines for misters or an outdoor kitchen.

Irrigation controllers usually need a fall schedule change. A walk around the yard at dusk helps you spot dry zones and spray heads knocked loose by summer storms. Our monsoon season tips cover what storms can do while you are gone.

Recreation cards and community access

Sun City, Sun City West and Sun City Grand are age-restricted (55+) communities; rules are in the CC&Rs and each recreation association sets its own card, dues and guest policies. In Sun City West, for example, the Recreation Centers' Member Services office handles annual owner dues, associate member fees and tenant cards, in person or through the member portal. Before peak season, confirm with your association:

  • Owner, guest and tenant card status
  • Gate remote or app access, if your community uses one
  • When club and class sign-ups open
  • Architectural rules if you plan patio or exterior work this winter

Take rules questions to the association itself. Our Sun City comparison and the Arizona 55+ living hub explain how the communities differ.

Mail, insurance and paperwork

USPS Hold Mail pauses all delivery for 3 to 30 days; for a longer absence USPS points you to mail forwarding. If you set a forward to your summer address, update or end it at usps.com so mail returns to Arizona. Keep your Hold Mail confirmation number, since you need it to change or cancel a request online.

Call your insurance agent to let them know the home is occupied again, especially if your policy has vacancy terms. If you keep a car in Arizona, check registration and insurance dates; our driver license and registration guide covers MVD basics.

If you are still shopping for a winter home

Some readers open this checklist while deciding whether to buy. During a purchase, ask how the seller handled summer shutdowns and which vendors they used, and read the HOA disclosures for guest, rental and seasonal rules. A lock-and-leave condo can cut down the list. For winter plans once you are back, see snowbird events in Phoenix, and the 55+ homes guide walks through the main communities.

Questions buyers ask

When should I restart utilities?
Before you arrive. Each provider has its own process, so check its official site or call a week or two ahead of your flight.

What should I check first inside the house?
Cooling, the water heater and every plumbing fixture, then look for pests in the kitchen, laundry room and garage.

Can USPS hold my mail all summer?
No. Hold Mail runs 3 to 30 days. For longer stays away, USPS offers mail forwarding instead.

Do recreation cards need renewing each season?
Each association sets its own rules. Confirm dues, card status and guest or tenant cards with your recreation center before peak season.

Is there a companion guide for spring?
Yes. Read closing up an Arizona home for summer so both ends of the season are covered.
