Making your home energy efficient and saving money are top priorities for homeowners. And a good way to save money on monthly bills is to cut down on your energy consumption. But aside from turning off the lights when you leave the room, knowing exactly what to do can be difficult. Below is a list of the top energy wasters in your home. By identifying what they are, you will be able to cut down your energy usage and save money!

Windows and doors

Most of us don’t think of our windows and doors as energy-suckers, but they are. And this is especially true if they are not properly sealed because cooled or heated air from inside the home is escaping outside. This heat loss in the winter and heat gain in the summer causes us to rely more heavily on our air conditioners and heaters to reach a comfortable temperature. And that excessive use will make your bills sky-high. 

According to experts, your heating system works hard to bring your home to the set temperature. If there are leaks in your doors or windows, your HVAC system has to work a lot harder because the heated or cooled air is going outside and not staying in your home. By fixing all open cracks and making sure your doors and windows are properly sealed, you will not have to use your HVAC system as often.. And that will make your home more energy efficient which will in turn lower your monthly bills.

Many homeowners incorrectly assume that if they have drafty windows, they need to have replacement windows installed, but that’s not really the case. The truth is, replacement windows will improve your home’s comfort and energy efficiency, but they don’t always get rid of drafts. When it comes to windows and doors, many times the gap between the framed window opening and the frame of the window, called the shim space, is the culprit. You can’t see the “shim space” with the naked eye, but you can feel the effects of an open shim space when it’s cold or hot outside. Chilly or warm outside air will find its way around the exterior trim into the shim space, and will go directly into your living space. Because of this, it is important to have a licensed HVAC technician thoroughly inspect all doors and windows. 

Old appliances

Older appliances like washing machines, dryers, dishwashers, and refrigerators waste a lot of energy. If any of these items in your home are more than 12 years old, replacing them is your best option for running a more efficient and inexpensive household. 

For example, modern, energy efficient front-loading washing machines can save you up to 85% on your energy costs and use up to 75% less water. So even though you might spend a little more on the purchase of your new machine, the energy efficient model will likely save you hundreds of dollars each year. And if you upgrade all your appliances to energy efficient models, the savings will really start to add up. 

Small loads

We already mentioned that washing machines, dryers, and dishwashers account for a significant amount of energy usage. Because they use so much water and energy, it is important to run them only when they are full. This keeps them from constantly running. If you only run them when they are full you will be surprised at the amount of money you can save!


No, we’re not talking about the “Twilight” series. We’re referring to all those appliances you keep plugged in and running even when they’re not in use. They might seem insignificant individually, but an old alarm clock in a rarely-used room, a video game console you haven’t fired up in months, a toaster oven with a clock on it, or your laptop charger plugged in even though your laptop is already charged — those “vampires” add up to a decent chunk of charges on your electric bill. Unplug them, and watch your expenses go down.

Air conditioner/Furnace 

Your air conditioner and furnace are two of the largest systems in your home, and keeping them maintained and in proper working condition is very important. Not doing so will drive up your energy costs. By having each system inspected annually, you are being proactive about discovering and fixing all problems before they get out of hand, waste excess energy, and cost you thousands of dollars to fix. 

By making a few small changes to your household, you will be surprised by the amount of money you’ll end up saving each month. If you have already made some changes and not seen any savings, call JW East Mechanical. Our experts will inspect your system inside and out to make sure it is running in optimal condition!
