Question: My electric bill seems too high. How can I perform a simple home energy audit myself?
Google AI Mode· Sep 23, 2026
Performing a DIY home energy audit is a straightforward way to track down where energy is being wasted and lower your utility bills . You can follow this simple, room-by-room guide based on recommendations from the Department of Energy Consumer Guide to Home Energy Assessments.
Step-by-Step DIY Energy Audit
Review your utility bills
Look back at the last 12 months of electric bills. This helps you see seasonal spikes, compare your usage to previous years, and establish a baseline. Many utility providers also offer online tools or energy-tracking apps.
Inspect for air leaks (Drafts)
Walk through your house and look for gaps where outside air can enter or conditioned air can escape.
Check areas where different building materials meet, exterior corners, and foundation-to-wood joints.
Inspect utility cut-throughs for pipes, gaps around chimneys, and recessed light fixtures.
The Incense Test: On a windy day, turn on all exhaust fans (like bathroom or kitchen vents) to pull air out, light an incense stick, and pass it slowly along the edges of windows, doors, baseboards, and electrical outlets. If the smoke wafts sideways, you've found a leak.
Check your insulation levels
Go up to your attic and look at the floor. Measure the thickness of the insulation. If it's less than the recommended R-value for your climate zone (often R-38 to R-60 for attics), adding more insulation can drastically cut heating and cooling costs. Check if exterior walls and accessible crawl spaces are insulated as well.
Evaluate heating and cooling equipment
Check your HVAC filters and replace them if they are dirty (do this monthly or quarterly).
Inspect your heating and cooling systems to ensure they have been tuned up recently.
Consider upgrading to a programmable or smart thermostat to automatically dial back temperatures when you are asleep or away.
Examine lighting and electronics
Walk around and count how many traditional incandescent bulbs you still have left and swap them out for LEDs.
Identify "energy vampires"—electronics like TVs, gaming consoles, and computer setups that draw power even when turned off. Plug these into smart power strips that cut power entirely when idle.
Assess large appliances and water heating
Check your refrigerator seals by closing the door on a dollar bill; if it pulls out easily, the seal is loose.
Check your water heater temperature (it usually only needs to be set to 120°F instead of higher default settings) and consider wrapping an older tank in an insulating blanket.
If you'd like, tell me:
What your primary heating and cooling source is (electric heat pump, gas furnace, baseboard, etc.)
The age and type of your main appliances
I can help you pinpoint which of these areas is likely causing the biggest spike on your bill.
A simple home energy audit can usually be done in an afternoon. The goal is not to inspect every wire or appliance—it’s to find the few things that are driving up your kilowatt-hour (kWh) usage. A DIY audit typically starts with your bills, then checks the biggest energy users: air conditioning/heating, water heating, appliances, lighting, and air leaks.

Performing a simple DIY home energy audit can help you track down where electricity is leaking out of your wallet. Here is a straightforward guide to doing it yourself room-by-room.
Check Your Utility Bills
Review past usage : Look at your statements from the last 12 months to see seasonal spikes and compare your kilowatt-hour (kWh) consumption to the same month last year.
Identify baseloads : Notice how much electricity you use when you're barely home or sleeping; a high baseline reveals appliances drawing phantom power or running inefficiently 24/7.
Inspect for Air Leaks and Drafts
The visual scan : Check around windows, doors, baseboards, electrical outlets, and where pipes or vents meet the walls. Look for daylight or peeling caulking.
: On a windy day, light an incense stick and hold it near common leak spots. If the smoke wafts wildly or blows sideways, you’ve found an air leak that needs weatherstripping or caulk.
1. Start with your electric bill
Before walking around the house:
Look at kWh used, not just the dollar amount.
Compare the last 12 months if available.
Note:
Months with the biggest spikes
Whether usage increased or only the electricity rate changed
Your “baseline” usage during mild-weather months
A large summer spike often points toward cooling loads, while a steady increase may point to appliances or always-on electrical loads.
2. Check your biggest energy users
Air conditioning / heating
In many homes, HVAC is one of the largest electricity users.
Check:
Is the air filter dirty?
Are vents blocked by furniture?
Does the system run much longer than it used to?
Are some rooms much hotter or colder than others?
Is the thermostat schedule more aggressive than needed?
Also inspect visible ductwork (especially in attics, garages, or crawl spaces) for disconnected sections or obvious leaks.
Water heater
Check:
Temperature setting (many homes use around 120°F as an energy-saving setting)
Hot water leaks
Whether hot water pipes are insulated
Whether an older electric water heater is running constantly
If you have an inexpensive plug-in energy meter, you can measure individual devices and identify “phantom” loads from electronics that use power while idle.
3. Hunt for air leaks
Walk around your home and look for drafts at:
Door frames
Window edges
Baseboards
Electrical outlets and switch plates
Attic access doors
Plumbing or wiring openings
Recessed lights
Simple tests:
Hold a tissue or thin strip of paper near suspected leaks.
Look for daylight around closed doors.
Check whether weatherstripping and caulk are cracked or missing.
The U.S. Department of Energy recommends checking these common leakage points during a DIY assessment.
4. Inspect insulation
Check accessible areas such as:
Attic insulation depth and condition
Gaps around attic hatches
Missing insulation around pipes, ducts, or wiring penetrations
Do not move insulation around electrical equipment unless you know it is safe to do so.
5. Review lighting
Make a quick inventory:
Replace remaining incandescent bulbs with LEDs.
Check outdoor lights that may run longer than needed.
Look for lights left on routinely.
6. Do a “whole-house power test”
A useful experiment:
Turn off unnecessary lights and appliances.
Check your electric meter or utility usage monitor.
Turn devices back on one group at a time.
Watch for large jumps.
This can help reveal unexpected loads.
7. Make a priority list
Create a simple table:
Finding
Possible fix
Cost
Priority
Drafty door
Weatherstripping
Low
High
Dirty HVAC filter
Replace filter
Low
High
Old refrigerator
Evaluate replacement
Medium/high
Medium
Always-on electronics
Smart power strip
Low
Medium
Start with low-cost fixes that you can measure afterward. Keeping notes and comparing future kWh usage makes it easier to tell what actually helped.
If you tell me your monthly kWh usage, home size, electric rate, and whether you have central AC, electric water heating, a pool, or an EV, I can help narrow down the most likely causes of the high bill.
Walk through your house and inspect primary trouble spots: windows, doors, electrical outlets, baseboards, switch plates, and attic hatches.
Use the dollar bill test on doors and windows: close a door or window on a dollar bill; if you can pull it out easily, the seal is too loose.
Use the incense test : light an incense stick and slowly pass it near seams, baseboards, and outlets. If the smoke wafts sideways or dances, you have an active air leak letting conditioned air escape.
Inspect Insulation Levels
Go up to your attic and check the depth of your insulation. Measure it with a ruler. Compare your findings to the recommended insulation levels for your climate zone to see if you are under-insulated.
Check if insulation is blocking any soffit or attic ventilation.
Examine Heating and Cooling Equipment
Locate your HVAC filters. If they are clogged or dirty, your system has to work drastically harder—and draw a lot more power—to circulate air. Replace them if they haven't been swapped in the last 1–3 months.
Check visible heating and ductwork in unheated areas (like crawlspaces or attics) for gaps, disconnections, or leaks. Sealing ducts can prevent massive energy losses.
Audit Appliances and Electronics
Identify energy hogs like a secondary old refrigerator in the garage, constant dehumidifiers, or space heaters.
Look for "phantom loads" (electronics that draw power even when turned off, like gaming consoles, TVs, and desktop setups). Plugging these into smart power strips can stop hidden drain.
Swap remaining incandescent bulbs for high-efficiency LEDs.
If you want to narrow this down, tell me:
What climate zone or region you live in
What your main heating/cooling source is (heat pump, gas furnace, baseboard, etc.)
I can give you a better idea of which fixes will save you the most money first.
Collect your last 12 months of bills and look for patterns:
Seasonal spikes:
Winter spikes may point to electric heating, heat pumps, space heaters, or poor insulation.
Summer spikes may point to air conditioning, fans, or dehumidifiers.
Always-high usage: Look for “base loads” that run all year, such as refrigerators, freezers, servers, aquariums, or standby electronics.
Write down your monthly kWh usage (not just the dollar amount), since rates can change.
2. Do a whole-house walkthrough
Use a flashlight and notebook. Record:
Location
Problem you find
Possible fix
Priority (easy/cheap vs. bigger project)
Check for drafts and air leaks
Look around:
Exterior doors and door sweeps
Window frames
Baseboards
Electrical outlets and switch plates on outside walls
Pipes, cables, and vents passing through walls
Attic hatches
Fireplace dampers
Simple tests:
Hold your hand near suspected gaps on a windy day.
Use a thin piece of tissue or incense smoke (away from combustion appliances) to see if air is moving.
Try the “paper test”: close a door or window on a sheet of paper; if it pulls out easily, the seal may be weak.
3. Inspect insulation
Check:
Attic insulation depth and coverage
Whether insulation is missing around attic edges, pipes, or fixtures
Basement/crawlspace areas if accessible
Uneven or thin insulation can make heating and cooling systems work harder. Be cautious in older homes—some insulation materials should not be disturbed without proper testing.
4. Look at your heating and cooling system
Check:
Air filter condition (replace if dirty)
Thermostat schedule
Blocked vents or registers
Outdoor heat pump/AC unit condition
Ducts in accessible areas for obvious gaps or disconnected sections
Heating and cooling are often among the largest energy uses in a home.
5. Find “phantom” electricity use
Many devices use power even when they appear off.
Walk around at night and look for:
TVs with standby lights
Game consoles
Chargers left plugged in
Computers and monitors
Smart speakers
Cable boxes
A plug-in energy meter can help measure individual devices if you want more detail.
6. Check major appliances
Look at:
Refrigerator: Is it very old? Are door seals tight?
Freezer: Is it in a hot garage?
Clothes dryer: Is the vent blocked?
Water heater: Is it set excessively high? Is the tank or piping losing heat?
7. Compare your “before and after”
After making changes:
Record your monthly kWh usage.
Compare similar months (for example, this January vs. last January).
Account for weather differences and changes in household habits.
Quick wins that often help
Seal obvious drafts with weatherstripping or caulk.
Replace frequently used bulbs with LEDs.
Turn off or unplug rarely used electronics.
Wash clothes with cold water when appropriate.
Adjust thermostat settings when away or asleep.
Clean HVAC filters regularly.
When a professional audit is worth considering
A professional assessment can measure things a visual check cannot, such as total air leakage with a blower-door test, hidden insulation issues, or combustion safety concerns.
If you tell me:
your home type (apartment, townhouse, single-family),
approximate age,
heating/cooling type (heat pump, electric furnace, gas, etc.),
and whether the bill is high in summer, winter, or all year,
I can help you narrow down the most likely causes.
You can complete a thorough walk-through and inspection of your house in under an hour without specialized tools. Follow these step-by-step actions to find and fix energy waste.
Step-by-Step DIY Home Energy Audit
Check for Air Leaks and Drafts
Inspect windows and doors : Look for daylight around frames or feel for moving air on windy days.
Check baseboards and outlets : Seal gaps along baseboards, electrical outlets on exterior walls, and pipe penetrations using caulk or weatherstripping.
Perform the incense test : On a windy day, light an incense stick and hold it near edges of windows, doors, and vents. If the smoke stream wavers or blows sideways, you have found an air leak.
Evaluate Insulation Levels
Check the attic : Measure the depth of insulation in your attic. If it is less than recommended for your climate zone (often R-30 to R-60, or roughly 8 to 15 inches depending on the material), you are losing heat or cooling.
Inspect exterior walls : Look into wall cavities during electrical updates or via uninsulated crawlspaces to see if wall insulation is present.
Hunt Down Phantom Loads (Standby Power)
Unplug unused electronics : TVs, gaming consoles, coffee makers, and phone chargers consume power even when turned off.
Use smart power strips : Plug entertainment centers or computer setups into a Smart Power Strip to cut power completely when devices are not in use.
Inspect Lighting and Bulbs
Count old incandescent bulbs : Walk through your home and list any remaining incandescent or compact fluorescent (CFL) bulbs.
Switch to LEDs : Replacing your most-used home lightbulbs with LEDs cuts lighting energy use by over 75% and dramatically lowers thermal output in summer.
Examine Heating, Cooling, and Appliances
Change HVAC filters : A dirty air filter forces your system to work harder, driving up electricity use. Replace filters every 1 to 3 months.
Check thermostat settings : Ensure your fan is set to "Auto" rather than "On" so it only runs when heating or cooling, saving up to $50 a month.
Test refrigerator seals : Close a dollar bill halfway in the refrigerator door and pull it out. If it slides out with no resistance, your door gasket is worn and letting cold air escape. Clean the coils beneath or behind the fridge as well.

If you want to narrow down which specific appliance is costing the most, would you like recommendations on how to use a plug-in electricity monitor (like a Kill A Watt meter) , or do you want to check local utility rebate programs for upgrades?
Absolutely. A simple DIY energy audit can usually identify the biggest sources of wasted electricity without special equipment. The key is to combine what your bill says with a room-by-room inspection.
1. Start with your electricity bills
Collect your last 12 months of bills and record:
Electricity used, preferably in kWh, for each month
Amount paid
Billing-period length
Any changes in electricity rates
Major changes in how you used the home
Look for whether the problem is high usage (kWh) or simply a higher price per kWh. A year of data is much more useful than comparing just two bills.
If your kWh suddenly jumped, that's a strong clue that something is consuming more electricity.
2. Identify your biggest electricity users
Walk through the house and make a list of anything that heats, cools, pumps, or runs for long periods.
Pay particular attention to:
Air conditioner or heat pump
Electric water heater
Space heaters
Refrigerator/freezer
Clothes dryer
Electric oven/stove
Pool or water pumps
Dehumidifier
Old appliances
Computers, TVs and entertainment equipment
Heating and cooling are often major energy consumers, while appliances, lighting and water heating can collectively represent a substantial portion of household energy use.
3. Hunt for air leaks
On a windy day, walk around windows, doors, baseboards, electrical outlets and pipe/wire penetrations.
Try:
Hand test: move your hand slowly around suspect areas and feel for drafts.
Paper test: close a door or window on a sheet of paper. If it pulls out very easily, the seal may be poor.
Light test: at night, have someone outside while you shine a flashlight around potential gaps.
Smoke test: incense smoke can reveal air movement around cracks.
DOE and ENERGY STAR specifically recommend these types of DIY checks.
Safety: Don't perform a smoke/depressurization test around operating gas, propane, wood-burning or other combustion appliances. Combustion appliances can create dangerous backdrafting conditions.
4. Check insulation
If you can safely access the attic, look at the insulation depth and whether there are obvious bare spots or compressed areas.
Also inspect around:
Attic hatches
Ducts
Pipes
Chimneys
Recessed lights
Electrical penetrations
Don't disturb old vermiculite insulation, which can contain asbestos.
5. Investigate your water heater
If your water heater is electric, it's worth special attention.
Check:
Is the temperature set unnecessarily high?
Are hot-water pipes insulated?
Is the tank itself poorly insulated?
Do you have a hot-water leak?
Does the heater seem to run unusually often?
DOE recommends around 120°F (49°C) as a typical water-heater setting, while noting that water heating can account for a significant share of household energy use.
6. Look for "always-on" electricity
Walk around the house at night and identify things that remain powered when nobody is using them.
Examples:
TVs and game consoles
Desktop computers
Printers
Speakers
Chargers
Routers/network equipment
Kitchen appliances with displays
Unused refrigerators/freezers
For a more precise test, an inexpensive plug-in electricity meter can tell you how many watts an individual appliance is actually consuming.
7. Do a quick lighting audit
Count the lights that are on for several hours each day.
Prioritize replacing frequently used inefficient bulbs with LEDs. DOE notes that lighting can represent roughly 10–11% of household energy use and that efficient lighting can substantially reduce that portion.
8. Check your cooling/heating equipment
If your bill is particularly high during hot or cold months, this is one of the first places I'd investigate.
Check:
Dirty/blocked filters
Outdoor unit blocked by vegetation or debris
Doors/windows left open while HVAC runs
Thermostat settings
Ducts that are disconnected or poorly insulated
Rooms that are dramatically hotter/colder than others
Sealing ductwork and addressing heating/cooling-system problems are among the measures ENERGY STAR recommends after an energy assessment.
9. Make a simple "energy suspects" table
You can use something like this:
Suspect
Evidence
Priority
A/C
Runs many hours/day
🔴 High
Electric water heater
Runs frequently
🔴 High
Drafty doors
Noticeable airflow
🟠 Medium
Old refrigerator
Very old/poor condition
🟠 Medium
Don't obsess over tiny standby loads before investigating the big stuff. A device using a few watts is unlikely to explain a dramatically higher bill; something heating, cooling, pumping or running continuously is much more likely.
10. Track the result
Make one change at a time when possible, then compare your next month's kWh with the previous year's comparable period.
For a deeper comparison, ENERGY STAR's Home Energy Yardstick uses your 12 months of energy use along with factors such as home size and occupants to benchmark your home's performance.
The quickest version
If you only have 30 minutes, do these five things:
Compare this month's kWh with the same month last year.
Check how many hours your A/C/heater is running.
Check the electric water heater.
Walk around looking for drafts and poor seals.
Identify appliances that are hot, running continuously, or unusually old.
If you tell me your monthly kWh, approximate home size, number of people, and whether your heating/cooling and water heater are electric, I can help you narrow down what is most likely driving the high bill.

The quickest version
If you only have 30 minutes, do these five things:
Gather the last 12 months of bills and write down the kWh used each month—not just the dollar amount.
Look for:
A sudden increase compared with the same month last year.
Seasonal spikes, which often point toward heating/AC.
A steady increase, which may indicate an appliance, water heater, or other continuous load.
Changes in usage after adding an appliance or changing thermostat settings.
The DOE recommends comparing utility bills and targeting the largest energy users first.
2. Check heating and cooling first
For many homes, HVAC is the biggest opportunity.
Walk around and check:
Is the thermostat set unusually high in winter or low in summer?
Are filters dirty?
Are supply/return vents blocked by furniture?
Do some rooms get dramatically hotter or colder than others?
Are ducts in an attic, crawlspace, garage, or other unconditioned area poorly insulated or visibly leaking?
Also inspect around doors and windows for drafts. Air sealing and insulation are among the most cost-effective improvements for many homes.
3. Do a quick draft test
On a cool or windy day, close windows and exterior doors.
Check around:
Door and window frames
Attic hatch
Plumbing and electrical penetrations
Baseboards
Recessed lights
Fireplace
Pipes entering exterior walls
Basement rim joists
You can use your hand to feel for moving air. For windows and doors, ENERGY STAR also suggests closing them on a piece of paper: if the paper pulls out easily, the seal may be inadequate.
Safety: If your home has combustion appliances such as a gas furnace or water heater, don't perform pressurization/smoke tests in a way that could cause combustion gases to be pulled into the house. For those situations, a professional assessment is preferable.
4. Look in the attic
If it's safely accessible, inspect the insulation.
You're looking for:
Thin or missing insulation
Compressed insulation
Wet insulation
Dark/dirty patches, which can indicate air movement
Gaps around pipes, wiring, ducts, and the attic hatch
Bathroom/kitchen/dryer vents improperly terminating in the attic
Large penetrations between the living space and attic can be particularly important to seal.
Don't disturb old vermiculite insulation unless it has been tested, because some vermiculite may contain asbestos.
5. Investigate your big electrical loads
Make a list of anything that produces heat, moves air, heats water, or runs continuously:
Electric water heater
Central AC/heat pump
Space heaters
Clothes dryer
Electric oven/range
Refrigerator/freezer
Dehumidifier
Pool equipment
Well pump
EV charger
Gaming/PC equipment
A particularly useful clue is what runs 24/7. A continuously running dehumidifier, second refrigerator, pool pump, or malfunctioning appliance can add a surprisingly large amount of consumption.
6. Check the water heater
If you have an electric water heater, it's worth investigating because heating water can be a substantial energy expense.
Check:
Temperature setting
Whether hot-water pipes are insulated
Whether the tank is old or poorly insulated
Whether the system seems to run unusually frequently
DOE recommends a water-heater setting around 120°F for energy savings and scald protection.
7. Hunt for "always-on" electricity
Look at entertainment centers, offices, and kitchens for equipment that remains powered even when you're not using it:
TVs
Game consoles
Computers/monitors
Printers
Speakers
Streaming boxes
Chargers
Coffee makers
Garage equipment
These standby loads aren't usually the biggest problem individually, but they can add up. A smart power strip can make it easy to disconnect groups of equipment when they're not needed.
8. If you want numbers, use a plug-in meter
A basic plug-in electricity monitor can tell you how many watts an individual appliance is consuming.
For example, if something uses 100 W continuously:
0.1 kW × 24 hours × 30 days = 72 kWh/month
Multiply that by your electricity rate to see what it actually costs.
For larger loads such as an electric water heater, HVAC system, or dryer, don't open electrical panels or work around live wiring yourself. Those are jobs for a qualified electrician/HVAC professional.
9. Make a simple priority list
After the inspection, rank findings like this:
Finding
Likely impact
Action
HVAC running constantly
High
Investigate filter, ducts, thermostat, system
Poor attic insulation/air leaks
High
Seal leaks; improve insulation
Electric water heater
High
Check temperature/condition/usage
Old second refrigerator/freezer
Medium–high
Measure its consumption
Pool/dehumidifier
Medium–high
Check runtime
Drafty doors/windows
Medium
Weatherstrip/caulk
Electronics on standby
Low–medium
Smart strips/unplug
A few inefficient light bulbs
Low
Replace with LEDs
Don't start by replacing every light bulb. Find the big loads first.
One very useful next step
If you tell me your approximate monthly kWh usage, electricity rate, home size, whether you have electric or gas heating/water heating, and what kind of AC/heat pump you have, I can help you narrow down what is most likely responsible for the high bill and give you a customized audit checklist.
Addressing these common energy drains can reduce your utility costs by 10% to 20%. Follow these key steps to locate and fix energy waste around your house:
Check for Air Leaks and Drafts
Inspect windows and doors : Feel for cold or warm air movement around frames, or use the incense test—hold a lit incense stick near the edges of your windows and doors. If the smoke wavers or blows sideways, you have a draft.
Look at exterior penetrations : Check where pipes, electrical conduits, and dryer vents pass through exterior walls. Seal small gaps with caulk and larger gaps with expanding foam.
Renew weather stripping : Replace flattened, cracked, or missing weather stripping on all exterior doors and operable windows.
Evaluate Insulation and Ventilation
Measure attic insulation : Measure the depth of the insulation in your attic. If it is less than the recommended depth for your climate zone (often R-30 to R-60, or roughly 8 to 20 inches depending on material), adding more can drastically cut heating and cooling loss.
Seal the attic hatch : Ensure your attic access door or hatch closes tightly and is insulated with weather stripping or a foam board glued to the top.
Manage Heating, Cooling, and Water
Check HVAC filters : Inspect your furnace and air conditioner filters monthly, and replace or clean them every 1 to 3 months. A dirty filter forces your system to work harder and run longer.
Optimize your thermostat : Keep your thermostat set to the warmest comfortable temperature in summer (around 78°F) and the coolest comfortable temperature in winter (around 68°F). Avoid keeping the system fan set to the continuous "on" position, which can inflate bills.
Insulate hot water pipes : Wrap accessible hot water pipes, especially those running through unconditioned basements or crawl spaces, with foam pipe insulation sleeves.
Hunt Down Phantom Power and Inefficiencies
Unplug vampire loads : Electronics like gaming consoles, coffee makers, and phone chargers draw "phantom power" even when turned off. Plug entertainment centers into smart power strips that cut power entirely when devices are idle.
Audit your lighting : Walk through your home and replace any remaining incandescent or older compact fluorescent bulbs with high-efficiency Energy Star LEDs.
Assess old refrigerators : If you have an old secondary refrigerator running in a hot garage or basement, consider recycling it. Unconditioned ambient heat causes old fridges to run non-stop, adding over $100 a year to your electric bill.
If you want to narrow down your focus, tell me:
What season or weather is causing the highest spikes in your bill?
What type of heating and cooling system do you use?
Absolutely. A simple DIY energy audit can usually identify the biggest sources of an unexpectedly high electric bill in 30–60 minutes. The goal isn't to measure every watt—it's to find the few things consuming the most energy.
1. Start with your electric bill
Look at your last 12 months of bills and write down:
kWh used each month—not just the dollar amount.
Your highest-usage months.
Whether the utility's electricity rate or fixed charges recently increased.
The billing period length; a 35-day bill can look unusually high.
Any change in weather, occupants, thermostat settings, or appliances.
If your kWh increased, you're using more electricity. If kWh stayed similar but the bill increased substantially, the problem may be your utility rate rather than your home.
You can also use ENERGY STAR's Home Energy Yardstick to compare your home's annual energy use with similar homes.
2. Do a "big energy users" walkthrough
Start with these, in roughly this order:
Heating and air conditioning
Check:
Is the HVAC running much more than usual?
Is the thermostat set unusually low/high?
Is the air filter dirty?
Are supply and return vents unobstructed?
Are ducts leaking or poorly insulated, especially in an attic or crawlspace?
Is an older refrigerator/freezer or window AC running continuously?
Heating and cooling are often the biggest opportunities for savings. The DOE specifically recommends maintaining HVAC equipment and replacing/cleaning filters regularly.
Water heating
If you have an electric water heater:
Check its temperature setting; 120°F is a common energy-saving target recommended by the DOE.
Look for hot-water leaks.
Notice whether the heater runs frequently when nobody is using hot water.
Check exposed hot-water pipes for insulation.
Refrigerator/freezer
Pay particular attention to:
An old second refrigerator.
A garage freezer.
Units running almost constantly.
Dirty condenser coils, if your model has accessible coils.
Extra refrigerators/freezers can be surprisingly significant electricity users.
Dryer
Check the lint filter and exhaust for blockage. A dryer that takes much longer than normal to dry clothes is wasting both electricity and time.
Electronics
Look around your TV/entertainment area, office and kitchen for devices that stay powered 24/7:
TVs
Game consoles
Computers/monitors
Speakers
Printers
Streaming equipment
Chargers
Cable/network equipment
For groups of devices, a switched power strip makes it easy to shut them down together.
3. Check for air leaks
Walk around the house looking at:
Exterior doors
Windows
Baseboards
Plumbing penetrations
Electrical outlets on exterior walls
Attic hatches
Recessed lights
Areas around chimneys
Pipe/cable penetrations through walls
ENERGY STAR recommends several simple DIY tests, including looking for visible gaps and using a paper test around doors/windows: close the door or window on a piece of paper; if the paper pulls out easily, the seal may be inadequate.
For a nighttime check, have someone outside while you shine a flashlight around suspected gaps—or look from the attic/basement for visible light coming through cracks.
Safety note: Don't perform smoke/incense tests around combustion appliances unless you understand the safety precautions; ENERGY STAR recommends turning off combustion appliances before that particular test.
4. Inspect your attic insulation
Take a flashlight and look at the attic insulation.
You're looking for:
Thin areas
Bare spots
Compressed insulation
Uneven coverage
Insulation that has settled significantly
ENERGY STAR notes that if insulation is level with or below the attic-floor joists, additional insulation may be warranted; if it's substantially above the joists and evenly distributed, adding more may not be cost-effective.
Don't disturb old vermiculite insulation—it can contain asbestos.
5. Do a simple nighttime electricity check
This is one of my favorite DIY tests.
Before bed, walk through the house and note:
Lights left on
TVs/displays illuminated
Computers running
Fans running
Appliances operating
Outdoor equipment
Pool/spa equipment, if applicable
HVAC operation
ENERGY STAR specifically recommends a nighttime audit to identify equipment that's operating when it shouldn't be.
If you have access to your utility's hourly electricity-use data, check it the next morning. A large amount of electricity being consumed overnight can be a huge clue.
6. If you want numbers, measure individual appliances
A plug-in electricity meter can tell you how much energy a particular 120V appliance is consuming.
For example, measure your:
Refrigerator
Freezer
TV/entertainment center
Computer setup
Dehumidifier
Portable AC
Space heater
Then estimate annual cost:
kWh used × your electricity price = cost
For example, if something uses 2 kWh/day and electricity costs $0.30/kWh:
2 × 365 × $0.30 ≈ $219/year
This makes it much easier to distinguish a genuinely significant load from something that's only using a few dollars a year.
7. Make a priority list
Don't start by replacing every light bulb. Rank your findings:
Finding
Likely impact
What to do
HVAC running constantly
🔴 Very high
Investigate thermostat, filter, ducts, system
Electric water heater
🔴 High
Check temperature/use/leaks
Old garage refrigerator/freezer
🟠 High
Measure its consumption
Major air leaks
🟠 High
The DOE similarly recommends targeting the largest energy consumer or largest bill component first, rather than trying to fix everything simultaneously.
One particularly useful next step
If your bill suddenly jumped, compare your current kWh with the same month last year. If you give me:
your current monthly kWh,
last year's kWh for the same month,
your approximate electricity rate ($/kWh),
house/apartment size,
whether heating is electric or gas,
whether you have central AC/heat pump,
and whether you have an electric water heater,
I can help you pinpoint the most likely culprit and make a personalized 15-minute audit checklist.

One particularly useful next step
If your bill suddenly jumped, compare your current kWh with the same month last year. If you give me:
Attic check : Safely peek into your attic to see if the insulation level is below the floor joists. If it is, you may benefit from adding more.
Wall and basement checks : Check exterior-facing walls and basement rim joists to ensure insulation is present and not damp or sagging.
Audit Your Lighting and Electronics
Count the incandescent bulbs : Walk through and list any traditional incandescent or older halogen bulbs left—replacing them with LEDs cuts lighting energy use by up to 80%.
Hunt phantom loads : Devices like TVs, gaming consoles, and desktop computers draw power even when turned off. Plug them into smart power strips so you can cut the power completely when not in use.
Assess Major Appliances and HVAC
Refrigerator seals : Close a dollar bill in the refrigerator door; if it pulls out easily with no resistance, the gasket is worn and letting cold air escape.
HVAC filters : Check your furnace and air conditioner filters. A dirty filter forces the system to work harder, driving up your kWh usage.
Water heater temperature : Check if your water heater is set above 120° F (49° C), which wastes standby energy.
If you'd like, let me know:
Your approximate monthly usage or bill amount
The age and type of your heating/cooling system
I can give you more targeted advice on where the biggest savings might be hiding.
