No matter the time of year, identifying and closing up leaks, gaps, and drafts will save you money on your utility bills. There are many ways to conserve energy in my house and be efficient about it at the same time.
Check for indoor leaks – check around doors that lead into the garage, windows, outlets. Can you see light? If you can, that means air is escaping.
Weather stripping or expanding foam insulation around doors & windows – this is very inexpensive to do. It only takes your time. You could have one pesky crack or leak that is costing you a lot of money on an annual basis. ($7 a month in the form of a higher energy bill comes out to be $84 per year. What could you buy with $84?)
Caulk around windows and make sure the caulking is neat and tight
Have your AC unit cleaned and checked – an AC unit that is dirty runs inefficiently. It will require more energy to run.
Change the air filters in your duct returns – this also helps air get to your AC unit and keeps it operating efficiently.
Insulate your home to modern standards – do you live in an older home? If you do, chances are you have outdated levels of insulation in your attic and possibly no insulation in your walls. Upgrading your insulation will save you money over the long term.
If you have old equipment, buy a new Heat and Air unit. Standards have changed over the years. New HVAC units are designed to use less energy and run more efficiently than old ones.
If you live in a hot weather state, install solar screens and watch your electric bills go down. (What is a solar screen? A solar screen goes on your window like any other screen but is fitted with a material that blocks the sun’s energy from entering your home. It may seem like it would block light from entering, but the material still allows the sun’s light in your home.)
This information came directly from ONG Natural Gas Matters March 2009 letter included in my bill:
“Check for indoor air leaks around baseboards, doors, fireplace dampers, attic hatches and air conditioners.
Fill gaps around pipes, wires, electrial outlets, foundation seals and mail slots.
Examine and repair caulking and weather stripping, especially around windows and doors.
Consider upgrading your windows and doors.
Plug and caulk exterior holes for faucets, pipes, electrical outlets and wiring. Be careful when sealing exterior openings to leave adequate ventilation for the fuel-burning appliances inside.
Get in your attic and look for deficiencies in insulation. Look for spots where you can see light coming in the attic.”
When we moved into our home last year, we noticed that the air conditioning unit was working overtime in the late afternoons. We have a bank of 8 windows on the west side of our home which faces the sun. We installed solar screens for approximately $500 and this has made a huge difference in the temperature in our home. I would estimate that our electric bill has been around 25% less this year. The key to the solar screens is the solar-tex material that prevents 70% or more of the sun’s energy from coming into your home.
