Energy efficiency doesn’t just come from high-end windows or upgraded insulation, your doors play a huge role too.
A few weeks ago, we got a call from a customer in Regina, let’s call him Mike from Albert Park. He wasn’t calling about winter drafts or snow piling up by the front step. Nope. It was the middle of a Saskatchewan heatwave, and his air conditioner was running nonstop.
“I’m cranking the A/C and the house still feels like a sauna,” he said. “Feels like I’m cooling the whole neighbourhood at this point.”
Sound familiar?
The Real Reason Your A/C Won’t Quit
Mike figured it was just the heatwave and sure, we’ve had a scorcher of a summer, but something didn’t feel right. His A/C was running constantly, and the house still wasn’t staying cool.
Now, to be fair, it could’ve been a number of things.
Old windows, poor insulation, even the A/C system itself can all be culprits when your home feels like it’s losing the battle against summer heat.
But in Mike’s case, it wasn’t the A/C.
After a quick visit, we found the real issue: his front door.
His old door had hairline cracks in the bottom panel, noticeable gaps between the door and the frame, and weather stripping that had long since given up doing its job. Hot air was pouring in, and cool air was leaking out. His A/C wasn’t broken, it just couldn’t keep up with the constant loss of cold air.
Doors Aren’t Just for Security, They’re Part of Your Insulation System
We get it. When you think of keeping your house cool, your first thought probably isn’t “I should replace my front door.”
But the truth is, your doors are part of what keeps your home comfortable year-round. A poorly sealed, uninsulated door is like leaving a window cracked open all day. And when the temperature hits 30+?
That’s a recipe for high energy bills and a tired-out A/C unit.
What Happened After Mike Replaced His Door?
He swapped out his old wood slab for a fiberglass door with a foam core and had it professionally installed with a snug-fitting frame and updated seals.
Here’s what he noticed within days:
- His entryway went from a hot zone to neutral temperature
- His A/C stopped running constantly
- His home cooled down faster and stayed that way
And his next SaskPower bill? Noticeably lower
What Makes a Door Energy-Efficient in the Summer?
Whether you’re dealing with +35° days or sudden prairie thunderstorms, here’s what to look for in a door that helps keep your A/C costs down:
- Foam-Insulated Core – Keeps cool air in and heat out
- Weather Stripping & Tight Fit – Blocks leaks and air gaps
- Insulated Glass (If Applicable) – Prevents heat transfer through decorative windows
- UV-Resistant Finishes – Helps your door last longer and resist warping
And most importantly? Proper installation. You can have the best door in the world, but if it’s not sealed right, you’re still wasting money.
Will It Really Save You Money?
Yes and not just in theory.
An inefficient front or back door can increase your cooling costs by 10-20%, depending on how bad the leaks are. In a place like Saskatchewan, where you’re dealing with extreme temperatures year-round, a high-performance door helps your HVAC system work smarter, not harder.
Final Thoughts from the Glacier Glass Crew
If you’ve got hot spots near your doors, if your entryway feels more like a sunroom, or if your A/C just won’t quit, your front or back door might be the hidden culprit.
Replacing it could be the difference between a house that stays cool and calm, or one that feels like a convection oven by 2 p.m.
So yeah, a new door can absolutely lower your A/C bill.
And no, you don’t have to suffer through another summer of sweating in your own home.
