An Oklahoma maintenance calendar should follow the weather: prepare drainage and storm plans in spring, reduce heat strain in summer, seal and service systems in fall, and protect plumbing during winter freezes. Inspect from safe locations after major wind or hail, address water intrusion quickly, and keep records of professional service and repairs.
What should you maintain in spring?
Clear drainage paths, inspect exterior seals and screens, service cooling equipment, test sump or drainage systems where present, refresh storm supplies, and check the roofline from the ground after winter and early storms.
What should you maintain in summer?
Replace or clean HVAC filters as the system and household require, keep the outdoor unit clear, watch for irrigation leaks, check attic heat and ventilation concerns with a qualified professional, and trim vegetation away from the structure.
What should you maintain in fall?
Schedule heating-system service, clean safe and accessible gutters, seal obvious drafts, inspect exterior caulk, disconnect vulnerable hoses before freezes, review tree hazards, and replace alarm batteries if your device instructions call for it.
What should you maintain in winter?
Monitor forecasts, protect vulnerable pipes, know the main shutoff, maintain safe clearance around heat sources, check for drafts and moisture, and avoid unsafe thawing methods. After a freeze, inspect slowly for leaks as temperatures change.
What should happen after severe weather?
Walk the perimeter only when safe. Look for displaced shingles from the ground, damaged vents, gutters, siding, fencing, trees, and outdoor equipment. Check the attic and ceilings for new moisture. Photograph concerns and arrange qualified evaluation where needed.
