Start with actual equipment
List the appliances, systems and exterior features the home really has.
Use manufacturer intervals
Filters, cleaning and service schedules vary by model and system.
Separate owner checks from professional work
Electrical, gas, structural and other regulated work should remain with qualified professionals.
Record completion
A date and short note make the next maintenance cycle easier to plan.
General household information only. Follow product labels and manufacturer instructions. Electrical, gas, structural, hazardous-material and other safety-critical work belongs to appropriately qualified professionals.
