Lock‑And‑Leave Tips For Desert Mountain Homes

Do you ever lock your Desert Mountain home and wonder what’s happening while you’re away? Between triple-digit heat, monsoon winds, and low humidity, Scottsdale’s desert climate can be tough on empty houses. You want to protect your investment without overcomplicating your routine. In this guide, you’ll get a simple, proven plan for HVAC, irrigation, pool care, plumbing, power, and security, plus HOA and insurance steps many owners overlook. Let’s dive in.

Why lock-and-leave matters in Desert Mountain

Desert Mountain sits in the Sonoran Desert, where summers are very hot and dry. Monsoon season runs roughly mid-June through September and brings high winds, dust, and fast-moving storms. The National Weather Service’s guidance on the region’s monsoon hazards explains why you need a plan for wind, debris, and power blips during summer monsoon events in the Phoenix area.

Heat and low humidity reduce mold risk, but they do increase stress on finishes, electronics, plants, and outdoor systems. Occasional winter freeze nights can also catch plumbing off guard. A clear checklist helps you prevent small issues from turning into expensive repairs while you are away.

Check HOA rules and insurance first

Before you set any switches, review your HOA documents. Many gated communities outline expectations for landscaping, visible clutter, exterior cameras, and absentee notifications. A quick scan of your CC&Rs and Rules and Regulations, along with resources from the Community Associations Institute, will clarify what you must do before an extended absence.

Next, call your insurance agent. Many policies include vacancy or occupancy clauses. Depending on your policy, leaving a home unoccupied for 30 to 60 days can limit coverage unless you meet certain conditions, such as regular inspections or monitored alarms. Learn the basics from the Insurance Information Institute’s overview of vacant and unoccupied homes, then confirm the exact requirements with your carrier.

Set your HVAC for Scottsdale

Proper HVAC settings protect interiors and manage energy.

HVAC setpoints and maintenance

• Summer cooling: set between 78 and 85°F. Use 78 to 80°F if you have sensitive finishes or electronics. The U.S. Department of Energy’s thermostat guidance supports balancing comfort and efficiency.
• Winter heating: do not set lower than 55 to 60°F to reduce freeze risk.
• Before a long absence, schedule a professional service to check filters, condensate drains, refrigerant, and electrical connections. Blocked condensate lines are a common source of water damage.
• Consider a smart thermostat with alerts so your home-watch contact can respond if temperatures drift out of range.

Manage water and irrigation the smart way

Water issues are the most common and the most damaging when you are away. Scottsdale encourages efficient outdoor watering and smart scheduling based on season.

Irrigation best practices

• Use a smart or ET-based controller that adjusts to weather. The EPA WaterSense program recommends irrigation controllers that adapt to conditions and help prevent overwatering.
• Make sure your schedule follows local rules. Check the City of Scottsdale’s water conservation guidance and adjust seasonally.
• Add a rain or monsoon pause, and consider flow sensors or moisture sensors to detect abnormal usage.
• Clean or replace clogged filters before monsoon season to handle dust.

Main water shutoff

Shutting off the main water can reduce flood risk but can also disable irrigation, auto-fill features, and some appliances. If you choose to turn water off, consult a licensed plumber for a proper shut-down and restart process. If water stays on, add monitored leak detectors and an automatic shutoff valve for peace of mind.

Keep pools and spas stable

Pools are active systems that need weekly checks to avoid algae, corrosion, or equipment damage.

• Hire a licensed pool service with weekly visits for chemistry, pump operation, and leak checks.
• Communicate heater and salt system expectations for your absence.
• If you plan a seasonal shut-down, ask a pool professional about partial winterization appropriate for Scottsdale’s mild winters.

Protect plumbing from rare freezes

Freeze events are infrequent but possible, especially on exposed pipes. Insulate exterior lines and keep interior heat at 55 to 60°F in winter.

• If water remains on, install monitored leak sensors and a flow sensor with an auto-shutoff valve.
• If water is off, follow your plumber’s sequence for draining lines, setting the water heater safely, and restarting appliances like icemakers and washing machines.

Power, appliances, and outages

• Keep refrigerators and freezers running, but empty perishables and place a temperature sensor on the appliance if possible.
• Add whole-home surge protection and a UPS for critical devices like your alarm hub or router.
• If you have solar, ensure your inverter and monitoring access are set up for a local service provider. Dust from storms may require periodic panel cleaning.

Security and access

• Maintain monitored alarms and notify your provider of your absence with a local keyholder. Use monitored smoke and water sensors if available.
• Lock all doors and gates, set smart locks to auto-lock, and remove spare keys from hiding spots.
• Use light timers or smart bulbs to create natural patterns. Manage package deliveries and USPS holds to avoid visible buildup.
• Exterior cameras can deter activity, but confirm HOA rules on placement and privacy before you install or point cameras.

Home-watch and vendor coordination

A reliable home-watch setup is your safety net.

• Verify licensing and insurance, check references, and agree on a written scope of work, reporting cadence, and emergency authority.
• Create a single “vacation folder” with vendor contacts, account numbers, entry instructions, and escalation rules. Note any gate procedures required by Desert Mountain.
• For water, HVAC, pool, and irrigation, ask each vendor to send date-stamped photos or dashboard screenshots after visits.
• For general water and drought context across Arizona, see the Arizona Department of Water Resources conservation resources and coordinate your irrigation accordingly.

Seasonal spotlight: monsoon and winter

• Monsoon season: Secure outdoor furniture, umbrellas, and grills. Check drainage paths and clear debris before storms. Expect dust that can clog filters and coat solar panels, so schedule cleanings as needed. Learn the basics from the National Weather Service’s Phoenix-area monsoon safety guidance.
• Winter nights: While winters are mild, occasional freezes can happen. Keep interior temps at 55 to 60°F and insulate exposed pipes.

Pre-departure

• Review HOA rules and register your absence with community security if required.
• Call your insurer to confirm vacancy requirements and inspection frequency.
• Schedule weekly pool service and home-watch visits, and confirm irrigation vendor support.
• Set thermostat: summer 78 to 85°F; winter at least 55 to 60°F.
• Set irrigation for the current season, enable monsoon or rain pause, and verify sensors.
• Empty perishables, keep refrigerator running, and add a temperature sensor if possible.
• Decide on main water strategy. If shutting off, follow a plumber’s procedure; if leaving on, activate leak and flow monitoring with auto shutoff.
• Test your alarm, provide a local keyholder, and update your alarm company profile.
• Secure outdoor items, lock gates and doors, and remove valuables from view.
• Place USPS and carrier holds or reroute packages.
• Provide access instructions and vendor authorization limits to your home-watch contact and, if applicable, gate staff.

Ongoing while away

• Home-watch visit: interior and exterior walk, check for leaks, run taps and flush toilets if water is on, verify HVAC operation, and check pool equipment.
• Vendor reports: request photos or screenshots of thermostat setpoints, irrigation controller status, and pool pump operation after each visit.
• Alerts: maintain mobile alerts for extreme temperatures, leaks, power outages, and camera motion. Tune camera sensitivity to avoid wildlife-triggered false alarms.

Monthly or seasonal

• Adjust irrigation schedules with seasonal changes and after major storms.
• Replace HVAC filters and schedule service per manufacturer guidance.
• Clean solar panels and exterior surfaces after dust storms.
• Inspect roof areas and drainage paths after monsoon events.
• Reconfirm insurer requirements before multi-month absences.

Emergency plan

• List your primary and secondary local contacts, HOA or community security number, and vendor list.
• Include your insurer’s claim line and policy number.
• Give clear authority for your home-watch contact or vendors to shut off water and authorize repairs up to a stated dollar amount.
