How to Do a DIY Home Energy Audit

When starting your DIY home energy audit, you must thoroughly walk through your home and inspect every area. It is advised to keep a checklist on hand to keep track of all the areas you have checked and what problems you have encountered.

1. Check Heating and Cooling Systems

  • Test all the equipment, if, for example, your thermostat or AC unit takes a long time to start up, perhaps they could be malfunctioning and therefore draining your home’s energy.
  • Check for accumulated condensation levels, make sure your duct vents are clean and dry.
  • Clean and replace the filters regularly.
  • Make sure to keep track of your hot water usage and make an adjustment to waste less.
  • Check the windows and doors; if there is a minuscule gap, foreign air could go in and cost unnecessarily.
  • Make sure your HVAC system is leveled.
  • For outdoor equipment, it is important to make sure there is no debris blocking your HVAC unit.
  • Make sure the fins or grill of your outdoor unit are clean, if clogged your system could malfunction, and it will cost you more money.
  • Make sure that the grill of your outdoor unit is not bent, this could slow down the airflow and waste a lot of energy.
  • Check your evaporator coil. It is in the access panel on the air handler unit. If there is dirt or mildew, it must be addressed immediately. A special spray cleaner should be used to clean the coils.

2. Inspect Insulation and Sealing

  • Examine the insulation level in the attic. Prior to doing so, it is advised to take safety precautions as not to injure yourself. It is recommended to wear a hard hat, safety goggles, a measuring tape, and a flashlight. At first glance, you must determine if the insulation in the attic is leveled. If it is not, insulation must be added to ensure an even spread over the attic floor. However, if the floor does not have exposed spaces, you probably have enough insulation, and adding additional insulation will be a waste of money.
  • Check your home for any air leaks. This is pivotal, unwanted air coming and going through cracks and gaps is not cost-effective. Many DIY methods have been popularized, here we will only outline a few simple ones. At night with a partner, shine a flashlight over all areas that could have cracks, and if the light can be seen from the outside, you have found an air leak. Another method that requires little effort is to shut a window or door over a piece of paper and then pull the said paper out. If you can pull it out without tearing the paper, then you have found an air leak.
  • Check your wall insulation level. There are a couple of methods to check your wall insulation. The first one is drilling a hole and examining the type and amount of insulation. The other method is shutting down the home’s electricity, and once the power is out, check the insulation levels behind and around each electrical socket. A thorough inspection must be made of all sockets because some homes may have an uneven level of insulation.

3. Account for Electricity Waste

  • Conserve your energy and use more natural lighting. This will decrease the need for electric lighting.
  • Turn off lights in rooms that are not occupied. This goes without saying, if no one is in that room, there is no need for lights to be turned on.
  • Fix leaky faucets. This is important, we may not think of how much this can impact our energy consumption, but it affects it a lot.
  • Take shorter showers, and don’t let the water run while brushing your teeth or shaving.
  • Unplug electronics that aren’t being used. This is especially relevant for appliances that are not in use frequently.
  • Don’t keep outdated appliances and electronics. Newer appliances and electronics come equipped with energy-saving capabilities therefore, this can save you a lot of money, investing in a new appliance will be beneficial in the long run.
  • Hang your laundry to dry when possible, especially in the summer. This is such an organic and old-fashioned way to dry your laundry, but you will notice a difference in your electricity bill almost instantaneously.
  • Don’t run a dishwasher or laundry machine when not full.
  • Cover windows with blinds or curtains to keep cold or hot air out.
  • When you’re not home, don’t waste energy by cooling or heating your house when it is unoccupied. Use a smart thermostat to conserve energy.

Important Safety Information

While performing an energy audit of your home, it is paramount to keep in mind your personal safety. Certain tools will help you perform the audit safely, and shortcuts should not be used to harm you or your loved ones. Some crawl spaces or vents can contain animal droppings or an accumulation of dust, so the appropriate clothing must be worn. When working with fiberglass, make sure you protect your eyes, lungs, and skin from any irritants that can endanger you. Before checking your home’s insulation levels, make sure to cut off the power at the breaker and not get electrocuted upon unscrewing electrical sockets.
