March Home Maintenance Checklist: Southwest

March in the Southwest means rising temperatures, increased pollen, and the transition from winter to spring. Homeowners should focus on energy efficiency, landscaping, and preparing their cooling systems for the warmer months ahead. Here’s your essential checklist.

1. Inspect & Service the Air Conditioning System

• Why It Matters: Temperatures will climb quickly, and a well-maintained AC system prevents breakdowns.

• Risk If Ignored: Reduced cooling efficiency, higher energy costs, and potential system failure.

• DIY Tip: Replace air filters, clean vents, and schedule a professional tune-up.

• Estimated Cost If Ignored: AC replacement ($4,000–$10,000).

2. Check & Adjust Irrigation Systems

• Why It Matters: Lawns and gardens require more water as temperatures rise.

• Risk If Ignored: Overwatering, wasted water, and stressed plants.

• DIY Tip: Inspect sprinkler heads, adjust watering schedules, and check for leaks.

• Estimated Cost If Ignored: Sprinkler system repair ($150–$500), full replacement ($2,000–$4,000).

3. Inspect & Maintain the Roof

• Why It Matters: Winter weather and wind may have caused wear and tear.

• Risk If Ignored: Leaks, insulation issues, and costly emergency repairs.

• DIY Tip: Look for cracked or missing tiles and inspect flashing around vents and chimneys.

• Estimated Cost If Ignored: Roof replacement ($7,000–$15,000).

4. Clean & Repair Gutters & Downspouts

• Why It Matters: Spring rains and monsoons require proper drainage.

• Risk If Ignored: Water pooling around the foundation, erosion, and mold growth.

• DIY Tip: Remove debris, flush gutters with water, and check for sagging or loose sections.

• Estimated Cost If Ignored: Foundation repair ($4,000–$12,000).

5. Seal Windows & Doors to Improve Energy Efficiency

• Why It Matters: Keeping cool air inside is critical as temperatures rise.

• Risk If Ignored: Higher energy bills, drafts, and strain on HVAC systems.

• DIY Tip: Apply weather stripping, caulk gaps, and install solar window films.

• Estimated Cost If Ignored: Window replacement ($300–$1,200 per window).

6. Prepare for Dust Storms & High Winds

• Why It Matters: The Southwest experiences strong spring winds and dust storms.

• Risk If Ignored: Outdoor furniture damage, clogged HVAC filters, and reduced air quality.

• DIY Tip: Secure outdoor furniture, clean or replace air filters, and check weather stripping on doors.

• Estimated Cost If Ignored: Storm damage repair ($3,000–$10,000).

7. Refresh Mulch & Landscaping

• Why It Matters: Helps retain soil moisture and reduces weed growth.

• Risk If Ignored: Dry, stressed plants and increased water consumption.

• DIY Tip: Apply a fresh layer of mulch, trim trees and shrubs, and fertilize garden beds.

• Estimated Cost If Ignored: Landscape repair ($1,500–$5,000).

8. Test Smoke & Carbon Monoxide Detectors

• Why It Matters: The transition into spring means increased use of gas appliances and cooling systems.

• Risk If Ignored: Fire hazards and carbon monoxide poisoning.

• DIY Tip: Replace batteries, test alarms, and install additional detectors if needed.

• Estimated Cost If Ignored: Fire damage restoration ($10,000+).

9. Clean & Maintain Outdoor Living Spaces
