Why Is My House So Cold?


A common complaint we hear from homeowners. “My thermostat is set at 73 and yet it always feels cold". There is nothing worse than to be paying big bucks for heat in the winter time, to only feel cold and uncomfortable. After all, that's why we have furnaces in the winter and air conditioning in the summer. There are many reasons why your Boise or Meridian home may seem cold all the time, even when the thermostat is set at your comfort level. I will address some of these reasons and provide viable solutions.

  • Check your windows and doors: Older homes don’t have energy efficient windows and doors. Many have single pane windows that allow heat to escape and cold to penetrate. Replace single pane windows with double or triple pane models. They will pay for themselves in no time at all.  Windows need to be caulked inside and outside. Doors need to have good seals. Use weather strip around doors to prevent heat loss. Protective clear film can be installed over windows to prevent heat loss. All these items can be purchased at your home improvement store.
  • Fireplace Damper: All fireplaces have a damper up inside the flue, above the fire box. Make sure it is securely shut to prevent heat loss. If you use your fireplace regularly, then you need to have an airtight fireplace door to keep the furnace air from escaping.
  • Ceiling Fans: As we all know, heat rises, so all that good warm air ends up at the ceiling. Especially in so many homes here in the Boise valley, have vaulted or high ceilings. Having your ceiling fans turn clockwise in the winter will push that air from the ceiling back down and keep then on low speed to avoid drafts. (In the summer you should switch them back to operate counter clockwise) You can run your fans 24/7. It will cost very little to do so. If they hum to loudly, then you might consider replacing it with a better-quality fan.
  • Leaking duct work can be the culprit: Your duct work is where all that nice warm air travels to each room of your house. If there is a break in the line, or duct work has come undone, then you will find you are heating your crawl space in the foundation or attic. Have one of our qualified technicians check your ductwork for heat loss. Make sure none of your vents are closed or covered up with boxes, furniture,
  • Incorrect size of furnace: If you have too small of a furnace and not putting out enough BTU's, then your house will always feel cold. As a rule of thumb, you need about you need 45-50 BTU for each square foot of your home. For example: A 1800 square foot home needs an 80,000 BTU furnace, there may be other factors involved, but this is a good gage to use. Along with more BTU’s, your furnace will generally have a larger blower motor to push all that warm air throughout your home.
  • Install a whole house humidifier: Your home should be at about 45% humidity in the winter. Central heat and air conditioning dry out the air. A furnace will draw moisture away from your skin and contribute to you feeling colder. A whole house humidifier puts the right amount of moisture in the atmosphere throughout your house. Moist warm air feels warmer than dry air. Consider installing our Trane or Aprilaire whole house humidifiers.
  • Poor, or insufficient insulation: Insulation in your floor joists or in your attic is your primary defense against heat loss in the winter. Each State has their recommendations or requirements for the amount you should have to meet code. You can check with your utility company to find out what is code for your area. Many utility companies, like Idaho Power, offer incentives for upgrading your insulation. You will never regret upgrading your insulation and often you will 'feel' immediate results.

     The things mentioned are the core problems for feeling cold all the time in your home. Most utility companies offer free 'home energy audits' to help you discover where you might be losing heat.
