If your energy bills seem to skyrocket every summer, you’re not alone—and it’s not just because the AC is running nonstop. For many Colorado homeowners, high summer energy costs are the result of a mix of outdated insulation, inefficient systems, and small air leaks that add up fast.
At Denco Contracting & Restoration, we specialize in helping homeowners reduce energy waste through smart upgrades that don’t just lower your bills—they improve comfort and boost your home’s long-term value. Here’s a closer look at why your summer energy bill may be higher than it should be—and what you can do to change that.
1. Poor Insulation = Lost Cool Air (❌ Lower energy bill)
Insulation isn’t just for winter. If your home lacks proper insulation, cool air escapes through your attic, walls, or crawl space—forcing your AC to work harder to maintain comfortable temperatures.
Signs your insulation needs attention:
Rooms that are hotter upstairs or near windows
Constant AC cycling
Insulation older than 15 years
Solution: Upgrading your insulation helps regulate indoor temps, reduce AC use, and lower monthly energy costs. Bonus: it also helps in winter!
2. Air Leaks Are Sneaky Energy Wasters
Small gaps around windows, doors, and vents may not seem like a big deal—but collectively, they let in hot air and let cool air escape.
How to spot them:
Drafts around window or door frames
Light peeking through cracks
Higher-than-average cooling bills
Solution: Seal leaks with weatherstripping, caulk, or foam sealant. For a bigger impact, Denco offers professional air sealing as part of our home efficiency upgrades.
3. Your HVAC System May Be Working Overtime
Even a well-maintained air conditioner struggles if it’s undersized, aging, or clogged with dust and debris. That extra strain leads to higher energy usage and reduced cooling power.
Solution:
Schedule a seasonal HVAC tune-up
Change air filters regularly
Consider upgrading to a more efficient unit if yours is 10–15+ years old
We can help you assess your system’s performance and recommend the right improvements.
4. Outdated Windows and Doors (= ❌ Lower energy bill)
Older windows and doors may lack the insulation or energy-efficient glazing needed to keep heat out. During Colorado summers, UV rays and direct sunlight can dramatically raise indoor temps.
Solution:
Upgrade to energy-efficient windows and doors
Add UV-blocking film or sun shades
Install insulated drapes or cellular shades
We can help you identify the most effective improvements based on your home’s design and exposure.
5. Roofing & Ventilation Issues
Dark, heat-absorbing roofs and poor attic ventilation can trap hot air, making your whole home warmer.
Solution:
Install a lighter, reflective roof material
Improve attic ventilation with ridge vents or fans
Add attic insulation to block heat transfer
Denco’s exterior services include roofing assessments and upgrades tailored for Colorado homes.
Long-Term Fixes = Long-Term Savings (= ✅ Lower energy bill)
Summer energy spikes can feel overwhelming—but the good news is, most of the causes are fixable. At Denco Contracting, we focus on efficient, high-quality upgrades that improve both comfort and performance.
