Why Energy Testing Matters in Southern Utah
Southern Utah homeowners face some of the highest cooling costs in the region. When summer temperatures soar above 110°F in St. George and surrounding areas, your air conditioner works overtime. But if your home has air leaks and duct problems, you're paying to cool the outside—literally throwing money out the window.
At High Desert Garage Door & More, we use professional diagnostic equipment to pinpoint exactly where your home is losing energy. A blower door test depressurizes your home to measure total air leakage, while our duct blaster equipment identifies leaks in your HVAC ductwork. Combined with thermal imaging cameras, we can see invisible problems that standard inspections miss.
The typical Southern Utah home loses 20-40% of its conditioned air through leaks and poor insulation. By identifying and fixing these problems, homeowners often see 15-30% reductions in their energy bills. For homes with monthly summer electric bills of $300-500, that's real savings that adds up year after year.

What to Expect During Energy Testing
Blower Door Test: We install a calibrated fan in your doorway that depressurizes your home to 50 Pascals. This simulates the pressure of a 20 mph wind on all sides of your house simultaneously, making air leaks easier to detect. We measure total air changes per hour (ACH) and compare to building standards.
Thermal Imaging: During the blower door test, we use infrared cameras to scan your walls, ceilings, windows, and electrical outlets. Temperature differences show up as color variations, revealing hidden air leaks, missing insulation, and moisture problems invisible to the naked eye.
Duct Blaster Test: We seal your air registers and pressurize your duct system to measure leakage. Many homes lose 20-30% of conditioned air through duct leaks—often in unconditioned attics or crawlspaces where that cooled or heated air does you no good.
Detailed Report: After testing, you receive a comprehensive report with photos, measurements, and prioritized recommendations. We explain which improvements will give you the best return on investment for your specific home and budget.

Frequently Asked Questions
How much does a blower door test cost in Southern Utah?
A blower door test in Southern Utah typically runs $250–$450 depending on home size and whether it's combined with duct blaster or thermal imaging services. A combined audit package that includes all three tests often provides the best value and the most complete picture of your home's energy performance.
How much can I save on energy bills after a blower door test?
Most Southern Utah homeowners who address the issues identified in a blower door and duct blaster test see 15–30% reductions in heating and cooling costs. For homes with summer electric bills of $300–$500, that translates to real annual savings that typically pay back the cost of testing within one to two cooling seasons.
What does a blower door test involve?
We install a calibrated fan in an exterior doorway that depressurizes your home to 50 Pascals — equivalent to the pressure of a 20 mph wind on all sides simultaneously. This makes air leaks detectable, and we measure your home's total air changes per hour (ACH50). We then use thermal imaging cameras to scan walls, ceilings, and outlets to locate specific leak points.
Is energy testing required for new construction in Utah?
Yes. Utah building codes require blower door testing for new construction to verify homes meet air tightness standards under the International Energy Conservation Code. We provide testing and certification for builders and work with your construction timeline to schedule testing at the required stage of completion.
What is duct blaster testing and why does it matter in Southern Utah?
Duct blaster testing pressurizes your HVAC ductwork to measure how much conditioned air leaks out before reaching your living spaces. Many Southern Utah homes lose 20–30% of their conditioned air through duct leaks — often in attics where summer temperatures exceed 150°F. Sealing those leaks is one of the most cost-effective improvements available.
Do I need to do anything to prepare my home for energy testing?
Very little preparation is needed. We ask that you close all windows and exterior doors before we arrive, turn off any fireplaces or combustion appliances, and ensure all interior doors are open. The test takes 2–4 hours for a full audit including blower door, duct blaster, and thermal imaging.
