How to Winterize Your Home

Dec 22, 2023

When it’s cold outside, our indoor heating system kicks into full gear to keep us warm. It’s also important for us to take steps to keep the chilly air outside. Winter energy bills can skyrocket as a result of air leaks, a faulty furnace, or a thermostat that’s set too high. Here are some indoor home winterization tips on how to winterize your home:

Winterization Checklist

There are certain key items every homeowner should have on their winterization checklist. Test your home heating system to make sure it’s functioning properly, turn down the thermostat, lower the water heater temperature, and seal up the fireplace. Taking these actions will help you save money on your winter energy bills. Let’s talk about what each step entails.

Schedule a maintenance check up for your heating system. Replace your filter monthly to reduce energy costs and keep your system running efficiently. Consider installing a programmable thermostat to help you regulate the temperature.

Turn down the thermostat if you want to save money on heating costs. Try adjusting it down 10 to 15 degrees for eight hours, such as while you’re at work. This step can save you around 10% on your annual heating and cooling bills. When you are home and sleeping, lower the thermostat to a temperature you can comfortably stand, and use extra blankets.  

Cool air loves to slip into your home through the fireplace. Have your fireplace and chimney inspected and cleaned. Keep the damper closed to keep the heat indoors. Also, consider installing glass fireplace doors and caulk around the hearth to seal up any leaks.

Lower the temperature on your water heater. This will reduce your energy bill. Water heating accounts for 18% of your home’s energy use. 

Up to 25% of home heating escapes through small cracks around windows and doors. Seal up the leaks with caulking or weather-proof strips. You can also install insulating films to your window frames. Energy efficient window coverings or drapes will reduce drafts. 

Other Energy Reducing Tips

Let the sunshine into your home through south-facing windows and doors. The sun will naturally heat up the room. Close the blinds and curtains at night to cut down on drafts. In bedrooms, rotate ceiling fans clockwise during the winter. This will pull warm air down into the room. Put rugs on bare floors to insulate them.  

Protect the Pipes

Don’t let frozen pipes wreak havoc in your home. Insulate any pipes that could be exposed to temperatures below 32 degrees. Let water trickle out of a few faucets when the temp drops to keep pipes from bursting. Open kitchen and bathroom cabinet doors to allow warm air to circulate around the pipes. Add insulation to attics, basements, and crawl spaces to warm things up.  

Maintain Your HVAC System

It’s important to have your HVAC system checked twice a year. Regular maintenance will help ensure optimal performance, energy efficiency, indoor air quality, and cost savings. A system that’s neglected will function inefficiently. Built-up dust, clogged filters, and worn-out parts will force the system to work harder and take a bite out of your budget.
