Maintenance Planning

The Preventive Maintenance Calendar That Cuts Emergency Calls

A seasonal schedule, component lifespans, and reserve math that turns surprise failures into planned spending.

Plan around component lifespan, not around complaints

Every major component has a usable life and a replacement cost. Water heaters run 8-12 years, asphalt roofs 20-25, HVAC condensers 12-18, and interior paint 4-6 between turns. Write down the install year for each one at every property. That single table converts capital planning from anxiety into arithmetic.

Four inspections a year beat one a decade

Quarterly walkthroughs catch slow leaks, failing caulk, and tenant-caused damage while it is still cheap. Announce them in writing with proper notice, tie them to filter changes so there is a functional reason to be there, and photograph everything.

  • Spring: roof and gutters, exterior caulk, AC service, grading and drainage.
  • Summer: irrigation, deck and railings, pest inspection, dryer vent.
  • Fall: heating service, water heater flush, weatherstripping, freeze protection.
  • Winter: pipe insulation check, smoke and CO detectors, attic moisture.

Fund the reserve like a bill

Total the replacement cost of each component, divide by its remaining life, and add the results. That annual figure, divided by twelve, is your true reserve contribution. Automate the transfer on the same day rent clears so the money leaves before it can be spent.

Make the vendor bench before the emergency

Interview two plumbers, two HVAC techs, one electrician, and one general handyman while nothing is broken. Agree on rates, after-hours policy, and who is authorized to approve work up to a set dollar limit. Emergency pricing is what you pay for not having done this.

Key takeaways

  • Record install years for every major component.
  • Quarterly inspections tied to filter changes pay for themselves.
  • Reserve funding is arithmetic once you know remaining life.
