How to Do a Home Energy Audit Yourself This Summer

If your July electric bill made you do a double-take, you’re not alone — and you don’t have to just accept it as the cost of an Oklahoma summer. Before you call anyone, you can spend an hour walking your own home the way a professional energy auditor would and find out exactly where your money is leaking out the doors, up through the attic, and off your air conditioner. Most of what a home wastes, it wastes in a handful of predictable places, and you can find every one of them yourself.

The trick is to do it on a hot afternoon with the AC running. The wider the gap between the cool inside and the 100-degree outside, the more obvious every leak and weak spot becomes. Grab a stick of incense or a thin piece of tissue paper, and let’s walk the house.

Start With the Envelope: Doors, Windows, and Leaks

Your home’s “envelope” is everything that separates inside from outside, and it’s where the easy wins hide. Hold your lit incense or tissue a few inches from the edges of exterior doors and windows while the AC is running. If the smoke wavers or the tissue flutters, you’ve found conditioned air escaping and hot air pushing in.

Work through these spots in order — they’re the usual offenders:

• Exterior door frames, especially at the bottom where the weatherstripping or door sweep wears out first.
• Window sashes and frames, particularly older single-pane windows.
• Where pipes, cables, and the dryer vent pass through exterior walls — these gaps are often wide open behind the escutcheon plate.
• Electrical outlets on exterior walls, which can leak surprising amounts of air. Foam gaskets behind the cover plates are a cheap fix.
• The attic hatch or pull-down stairs, which are frequently uninsulated and unsealed.

Most of what you find here is DIY territory: a tube of caulk, a roll of weatherstripping, and an afternoon can close the majority of it.

Go Up to the Attic

In an Oklahoma summer, the attic is the front line. It can hit 130–150 degrees up there, and if the insulation between that oven and your ceiling is thin, patchy, or matted down, that heat pours straight into your living space and your AC never gets a break.

You don’t have to crawl through it — just open the hatch and look. Can you see the tops of the ceiling joists poking up through the insulation? Then you’re low. Oklahoma homes generally want insulation in the R-38 to R-49 range, which looks like a deep, even blanket well above the framing. While you’re up there, check that no insulation is blocking the soffit vents and that any ductwork you can see isn’t obviously crushed or disconnected.

Insulation is one of the highest-return upgrades in our climate, and it’s the audit finding most likely to move your bill in a real way. If your attic comes up short, professional attic insulation fills the gap evenly and gets your ceiling back to a proper R-value — the kind of fix that keeps paying you back every hot month for years.

Check the System Doing the Most Work

Your air conditioner is the single biggest energy user in the house during summer, so it deserves a close look.

• Pull the filter. If it’s gray and packed, that alone is choking airflow and forcing the system to run longer for the same cooling. Change it and note the date.
• Feel the air at a few vents. Weak flow in far rooms points to duct leaks or balance problems that waste the cooling you’re paying for.
• Look at the outdoor unit. Grass clippings, cottonwood, and leaves packed against the coil make it dump heat poorly. Clear two feet around it.
• Watch how it cycles. A system that runs almost constantly on a normal afternoon, or that short-cycles on and off every few minutes, is telling you something’s off — from low refrigerant to a unit that’s simply worn out.

A clean filter and a clear condenser are free. If the airflow or cycling seems wrong, that’s the point where an audit turns up something a homeowner can’t fix alone.

Don’t Forget the Water Heater and Phantom Loads

Two smaller drains add up more than people expect. Put your hand on your water heater tank — if it’s warm to the touch, it’s radiating heat you paid to make, and an insulating blanket (on an electric unit) helps. Setting it to around 120 degrees is both safer and cheaper than the factory-hot default.

Then there are “phantom loads” — the devices sipping power around the clock. Entertainment centers, old game consoles, spare fridges in a hot garage, and stacks of chargers all draw energy even when idle. A power strip you can switch off, or simply unplugging the garage beer fridge you forgot about, quietly trims the bill.

What to Do With What You Found

By now you should have a short list, and it usually sorts itself into three piles:

1. Do-it-today fixes — change the filter, clear the condenser, caulk an obvious gap, switch off phantom loads.
2. Weekend projects — weatherstrip the doors, gasket the outlets, add a water heater blanket.
3. Call-a-pro items — thin attic insulation, ductwork that’s leaking or disconnected, an AC that runs constantly or short-cycles. These are the ones with the biggest payoff and the least DIY-friendly access.

The point of an audit isn’t to fix everything at once. It’s to stop guessing — to know which changes will actually move your bill instead of throwing money at the wrong thing.

The Bottom Line

A high summer bill isn’t a mystery you have to live with. An hour with a stick of incense and a look in the attic will show you where your home is bleeding energy, and most of the small stuff you can handle yourself the same day. The big-ticket findings — weak insulation, leaky ducts, a struggling AC — are exactly where professional help pays for itself fastest.
