🏠 Home Winterization Guide

Prepare your home for cold weather and protect your investment.

Winterization is the process of preparing your home for freezing temperatures, snow, and harsh winter conditions. Completing these steps in the fall helps prevent:

• 🧊 Burst pipes from freezing
• 💨 Heat loss from drafts and poor insulation
• 🏚️ Damage to exterior systems and structures

---

🔥 Heating System

Since your heating system works the hardest in winter, inspect it early:

• 🌡️ Raise the thermostat to test the furnace response
• 🧼 Replace the air filter at least once per season
• ⛽ Fill oil or propane tanks before winter arrives

---

❄️ Cooling System

Shut down and protect cooling equipment before winter:

• 🚿 Clean debris from the outdoor AC unit with a hose
• 🛡️ Cover the unit with a breathable waterproof cover
• 🪟 Remove window AC units to prevent drafts
• 🔄 Reverse ceiling fans to clockwise rotation to push warm air down

🪟 Building Envelope (Air Sealing)

Reduce drafts and heat loss:

• 🖐️ Check for air leaks around windows, doors, and outlets
• 🔥 Test drafts with your hand or an incense stick
• 🧰 Seal gaps with weatherstripping, caulk, or insulation tape
• 🏠 Inspect attic insulation (about 12 inches recommended in colder climates)
• 🚪 Install storm doors and windows

🧱 Insulation

Keep your home warm and energy-efficient:

• 🏠 Inspect insulation in attics, basements, and crawlspaces
