Winterizing your home photoAccording to the US government, Americans spend $241 billion each year on home energy bills or $2,100 per household! Those numbers are dizzying when you consider much of this energy usage is unnecessary. With proven preventative measures and the energy efficient products available, homeowners can save up to 30% on their energy bills. While some of the energy efficient upgrades are costly up front, such as installing an energy efficient furnace, a taxpayer may claim a credit of 30% of qualified expenditures.

Winterizing your home is one of the proactive activities which lead to big savings on your energy bills. Many variables are involved in calculating this savings, Home Energy Saver, provides a terrific tool for calculating your energy savings according to your zip code and details you provide about your home. The tool provides information on all energy end uses including heating, cooling, water heating, appliances and lighting. One Colorado homeowner claims to save thousands each year from implementing the suggestions on the site.

Below we've provided a checklist of the top ways to winterize your home for increased energy efficiency and long-term savings. Additionally, you'll find a resource list for tools and suggestions to help you winterize and increase the energy efficiency of your home.


Prepare Windows, Doors & Interior Elements

EarthWorks Group reports that the average home has air leaks that when combined are equal to a nine-foot square hole in the wall. Finding and blocking leaks around windows, doors, baseboards, electrical outlets and recessed lighting will resolve the issue and provide an energy savings of between 5 to 45 percent.

Prepare windows for winter

  • Install storm doors and windows
  • Insulate windows and doors
  • Block air leaks and drafts around windows and exterior doors with weather stripping
  • Replace cracked glass in windows and doors
  • Use door sweeps or draft snakes under doors to block drafts that can't be blocked with weather stripping
  • Install outlet gaskets around all electrical outlets
  • Block leaks around recessed lighting


Maximize Insulation

While this may be one area of winterization that can cost the most up front, you'll realize a tax savings from the federal government of up to $1,500 to cover the cost. Once your home is insulated you may realize a savings of more than $100 a year.

  • Visit to determine how much insulation you need by zip code
  • Identify and fix moisture problems
  • Insulate the crawl space and attic door
  • Install wind baffles along the attic eave and in cathedral ceilings
  • Use high R-value insulation on exterior walls and cathedral ceilings
  • Insulate the garage door- find out how to insulate a garage door


Service Heating Systems

Servicing your home's heating systems and taking proactive steps to block energy leaks can lead to big savings over time. The simple act of tuning-up your furnace can reduce heating costs by up to 5%.

Change your furnace filter regularly

  • Check the thermostats to make sure they are working properly
  • Replace old thermostats with programmable models to save as much as $180 a year
  • Open register vents and air returns inside the house
  • Repair or replace damaged/loose vents
  • Install an energy efficient furnace if you are operating on an out-dated unity- this can lead to savings of nearly $200/year
  • Check, clean and replace furnace filters monthly during cold seasons
  • Have your gas, oil, or other non-electric heating system serviced by a professional
  • DIY: Bleed air from the hot water radiators, and turn the gas furnace pilot light on
  • Insulate the water heater and turn down to 120 degrees Fahrenheit thus reducing water heating costs 6% to 10%
  • Have the chimney swept and keep damper closed when not in use


Seal Ducts

Seal air ducts to minimize heat notes that leaking ducts can reduce energy efficiency by 10 to 30%. Simple duct sealing will save you almost $100 a year.

  • Check and clean interior duct work for mold, dirt and debris accumulations
  • Patch holes in interior duct work
  • Check and clean exposed ductwork for nests or other obstructions before turning on your heating system
  • Check and patch holes in exposed duct work for damage from animals and outdoor elements
  • Insulate exposed ductwork under the house and in unheated areas


Weatherize the Foundation and Exterior

Taking weatherizing measures around the foundation and exterior of your home will add to the overall increased energy efficiency you'll experience from insulating and duct sealing. Gaps and holes in your house's exterior contribute to drafts, air leaks and the possibility of ductwork damage by pests.

Cover exposed pipes with insulation

  • Insulate plumbing that runs through unheated spaces such as crawlspaces, basements and garages

  • Seal entry points and cracks in house's foundation
  • Secure crawlspace entry points
  • Insulate the basement
  • Check and repair window wells around basement windows
  • Install plastic shields on basement windows
  • Cover central air units with heavy protective material


Use an Energy Monitor

Smart technology isn't relegated to your phone, an energy monitor will keep you on top of your energy usage in real time and projects your total monthly bill. This intelligent device, research reveals, leads to significant reduction in electricity consumption saving many users 15 to 20% on their energy bills, the equivalent to several hundred dollars a year. The device displays the exact amount of electricity being used by each appliance or activity allowing the user to cut waste based on facts.


Amp Up Energy Savings Practices Inside

Simple energy saving practices performed in the home on a daily basis can go a long way in lowering your winter heating bills. For example, for every degree you lower your thermostat you will save up to 3% on your energy bill!

  • Layer your clothing to keep the chill off and stay comfortable during the day and evening
