Climate and upkeep

Department of Energy (PNNL), 2021 IECC zones

The home energy code (IECC) puts Lewis and Clark County in zone 6B: cold.

The zone's number says how hot or cold it gets; the letter says how humid: A is moist, B is dry and C is marine.

  • Spring

    • Book the air conditioner's check-up before the heat: ENERGY STAR advises checking the cooling system in the spring, because contractors get busy once summer comes. ENERGY STAR (EPA)
    • Clean and repair the roof gutters. EPA

  • Summer

    • Seal the air ducts that run through the attic, crawlspace, basement or garage with duct mastic or foil tape, then wrap them in insulation. ENERGY STAR (EPA)
    • Check that the ground slopes away from the house, so water does not collect around the foundation. EPA

  • Fall

    • Book the heating check-up in the fall. If it runs on gas or oil, the technician should check the connections: faulty ones are a fire hazard. ENERGY STAR (EPA)
    • Seal air leaks and add insulation in the attic: ENERGY STAR says it lowers the chance of ice dams on the roof in snowy climates. ENERGY STAR (EPA)

  • Winter

    • Get the house ready for the cold with insulation, caulking and weather stripping, and learn how to keep pipes from freezing. Ready.gov (FEMA)
    • Put clear plastic film over the windows: it is inexpensive, cuts drafts, helps the house feel warmer in winter and reduces moisture on the glass. ENERGY STAR (EPA)

All year

  • Check the air filter every month, especially in heavy-use months. If it looks dirty, change it; change it at least every 3 months. ENERGY STAR (EPA)
  • Test the smoke alarms every month and replace their batteries at least once a year. USFA (FEMA)

Each task comes from the official page beside it. The spring air-conditioning and fall heating check-ups are the timing ENERGY STAR advises; the rest is a suggested order.
