The Arizona home maintenance calendar

Start with your climate and a recurring home check

Prepare cooling before sustained heat, inspect roofs and drainage before summer storms, and prepare exposed plumbing before freezing weather. Use the months below as planning prompts for desert communities such as Mesa, Queen Creek and Casa Grande. At higher elevations, move winter preparation ahead of the first freeze and follow your local forecast; a single Arizona schedule cannot fit every property.

Create one home log with the date, observation, photo, action and next check. Add equipment model numbers and maintenance intervals from their manuals. Once a month, review filters, visible leaks, irrigation settings and open repairs. That monthly review is a practical reminder, not a requirement to replace every filter or service every system monthly.

November–January: adjust watering and prepare for cold

Review the irrigation controller as conditions cool. Match watering to plants, soil and recent rain instead of leaving the summer program unchanged. Walk each operating zone where safe and note broken emitters, spray on paving or new pooling. Photograph the settings before changing them so the adjustment has a record.

Before forecast freezes, locate the household water shutoff, check protection on exposed pipes and consult your irrigation manual or a qualified provider about winterization. Prescott's advice includes disconnecting garden hoses and insulating outside pipes. Do not assume its full seasonal irrigation shutdown procedure applies to an actively growing desert landscape. If you leave for the season, make a property-specific heating and water plan.

February–April: prepare cooling and close pest entry points

Arrange cooling maintenance before the hottest period. Follow equipment instructions for accessible filter cleaning or replacement, and keep leaves and debris away from the outdoor unit. Ask the technician to explain the condition of coils, drainage and electrical components, separating maintenance from proposed repairs. The Department of Energy identifies clogged filters, drainage problems and refrigerant leaks as common cooling issues; refrigerant and electrical faults belong with a trained professional.

Check door sweeps, window screens and visible gaps around service penetrations. Repair damaged screens, keep food and pet food sealed, and address leaks that supply pests with water. Record photos and locations of recurring sightings so a pest professional can identify the problem before proposing treatment. Pest prevention is a recurring task, not a reason to apply a pesticide on a calendar without identifying a pest.

May–June: finish roof and monsoon preparation

The National Weather Service defines the Southwest monsoon season as June 15 through September 30. Complete preparation before storms arrive: arrange a roof inspection for unresolved leaks or visible damage, check drainage routes from ground level, and secure loose patio items. Photograph roof edges and interior stains you can see safely. Ask the roofer to identify the roof system, show the defect and explain the repair; do not climb onto a roof for this checklist.

Save utility outage and repair contacts, charge backup devices and decide where the household could cool down if air conditioning is unavailable. Follow local warnings and stop outdoor inspection when storms approach. Keep clear of downed power lines and floodwater; a maintenance task can wait until conditions are safe.

July–September: watch water use and maintain the pool

After rain, revisit irrigation before the next automatic cycle; avoid unnecessary watering during or after rainfall. Compare water use with your recent pattern and investigate unexplained changes instead of assuming every increase is heat-related. Note whether the change follows a controller adjustment, pool refill or visible leak, and send that record to the relevant provider.

For a pool, follow its equipment instructions and service plan for cleaning, filtration and water testing. Inspect accessible equipment for visible leakage. If you suspect water loss, Mesa's pool-leak guidance explains a bucket comparison to distinguish evaporation from a likely leak; follow the full procedure and ask a pool professional to investigate an abnormal result. A suitable cover can reduce evaporation; select and use it according to its instructions. This check does not replace sanitation or required barriers.

October and after any storm: close the repair loop

When conditions are safe, compare new roof, ceiling and yard observations with earlier photos. Record the date of a new stain, displaced material or recurring drainage problem and arrange an assessment. Report storm damage promptly to your insurer and ask about documentation before authorizing substantial repairs. A photograph records a symptom; it does not establish its cause or coverage.

For repairs, check the contractor's current ROC record and relevant classification before signing. Keep the scope, before-and-after photos, invoice and warranty together. At the next seasonal review, check whether the symptom returned. Move unresolved items into next year's plan instead of marking a job complete solely because an invoice was paid.

Keep the record

Save dates, photos, estimates, invoices, warranties, and the exact scope of work for future reference.
