Test For Air Leaks and Drafts to Reduce Energy Loss

Properly sealing cracks and openings in you home can significantly reduce heating and cooling costs throughout the year. You may already know where some air leakage occurs in your home, such as an under-the-door draft, but you’ll need to find the less obvious gaps to properly seal your home.

Here are several tests that can be used to check for air leaks:

  1. Window Seal Check – Shut the window on a piece of paper. If paper can be pulled without tearing paper, than window should be resealed.
  2. Visual Gap Check – After daylight hours, shine a light through closed window and door seam and have a partner confirm if light is visible on other side.
  3. Hot/Cold Air Check – Use your hands to feel around door and window seal checking for cold or hot air coming in through a leak.

Common areas to check for leaks are between brick and wood siding, between foundation and walls, and between the chimney and siding. In addition, you should inspect around these areas for leaks and drafts:

  • Door and window frames
  • Mail chutes
  • Electrical and gas service entrances
  • Cable TV and phone lines
  • Outdoor water faucets
  • Where dryer vents pass through walls
  • Bricks, siding, stucco, and foundation
  • Air conditioners
  • Vents and fans

Home Pressurization Test

If you are having difficulty locating leaks and drafts, you may want to conduct a basic building pressurization test:

  1. First, close all exterior doors, windows and fireplace flues.
  2. Turn off all combustion appliances such as gas burning furnaces and water heaters.
  3. Then turn on all exhaust fans (generally located in the kitchen and bathrooms) or use a large window fan to suck the air out of the rooms.

This test increases infiltration through cracks and leaks, making them easier to detect. You can use incense sticks or your damp hand to locate these leaks. If you use incense sticks, moving air will cause the smoke to drift, and if you use your damp hand, any drafts will feel cool to your hand.

Energy-efficient Window Covering Tips

The use of exterior and interior window coverings can help keep your home comfortable year long. With a few changes you can reduce annual electricity usage.

Here are a few low cost window covering tips:

  • Close draperies¬† to block the sun’s heat during the warmer months and to keep out the cold air during the colder months.
  • Use drapery seals to seal drapery edges to the side of windows using magnetic or velctro tape to maintain the seal around draperies.
  • By completely closing and lowering blinds, you can reduce heat gain by 45% – 50%.
  • Affix curtain liners to draperies to help keep heat inside your home.
  • Mount storm windows inside or outside your home made from furring strips and plastic sheets to increase winter comfort and reduce heat loss during the winter.
