Why Your Oklahoma Energy Bills Are So High (And How to Fix Them)
If your OG&E or PSO bill feels out of control in summer or winter, you’re not alone. Oklahoma has some of the most extreme temperature swings in the country — and most Oklahoma homes were built with insulation that doesn’t hold up.
The problem usually isn’t your HVAC system. It’s your building envelope.
Where Your Money Is Going
In a typical Oklahoma home with original fiberglass insulation, here’s the energy loss breakdown:
- Attic / roof: 25–40% of total energy loss
- Walls: 15–25%
- Air leaks (gaps, cracks, penetrations): 25–40%
- Windows and doors: 10–15%
Notice that attic and air leaks together account for 50–80% of your energy loss. Your HVAC system is fighting a battle it can’t win — conditioned air escapes through thousands of tiny gaps, and unconditioned attic air pours in through the ceiling.
Why Fiberglass Insulation Fails in Oklahoma
Most Oklahoma homes built before 2010 have fiberglass batts in the attic — the pink or yellow rolls stapled between joists. Here’s the problem:
Fiberglass doesn’t air seal. It slows heat transfer through the material itself, but wind and air pressure push right through it. On a windy Oklahoma day, your attic insulation is essentially bypassed.
Fiberglass compresses and sags. After 15–20 years, batt insulation loses 20–40% of its original R-value. Walk into your attic and look — you’ll likely see gaps, compressed sections, and areas where the insulation has shifted away from where it’s supposed to be.
Fiberglass gets wet. Humidity, roof leaks, and condensation degrade fiberglass performance. Wet fiberglass has almost zero insulating value.
The Fix: Spray Foam Your Attic
Spray foam insulation at the roofline does what fiberglass can’t:
- Seals every gap — Foam expands to fill cracks, penetrations, and irregular surfaces. No more air bypassing your insulation.
- Delivers higher R-value — Open cell spray foam at 5.5 inches provides R-20+ in a continuous, unbroken layer.
- Lasts permanently — Spray foam doesn’t sag, compress, or degrade. It maintains full performance for the life of the structure.
What Real Homeowners See After Spray Foam
These numbers come from our Oklahoma customers tracking their bills before and after:
| Before Spray Foam | After Spray Foam | |
|---|---|---|
| Summer bills | High | 30–50% lower |
| Winter bills | High | 30–50% lower |
| Overall energy savings | — | Significant year-round |
Most of our customers see their insulation investment pay for itself within 3–5 years through energy savings alone. After that, the savings continue for the life of the home.
But My HVAC Tech Said I Need a New System
Maybe. But before you invest in a new HVAC system, fix the envelope first. We’ve seen countless cases where a homeowner replaces their AC unit, still gets high bills, and then discovers the real problem was insulation all along.
A properly insulated and air-sealed home often lets you downsize the HVAC system — a smaller, more efficient unit running less frequently in a tight envelope outperforms an oversized system fighting a leaky house.
Quick Self-Check
Walk into your attic on a summer afternoon. If it’s 130°F+ up there, that heat is radiating through your ceiling into your living space — and your AC is working overtime to fight it.
Now look at your insulation:
- Can you see the tops of the ceiling joists? Your insulation has compressed below useful levels.
- Are there gaps around light fixtures, plumbing stacks, and wiring? Air is pouring through those.
- Is the insulation discolored or matted? It’s been exposed to moisture.
If you checked any of those boxes, your insulation is the problem — not your HVAC.
