What Is a Home Energy Audit?

A professional home energy audit (also called a home energy assessment) is a comprehensive inspection that identifies where your home is wasting energy — and how to fix it.

What auditors test:

Air leaks (windows, doors, outlets, attic access, basement)
Insulation levels (attic, walls, basement, ductwork)
HVAC efficiency (furnace/AC performance, duct leaks)
Thermostat programming (settings, scheduling, placement)
Hot water heater (age, efficiency, temperature setting)
Lighting & appliances (energy usage patterns)
Windows & doors (U-factor, weather-stripping)

At the end, you receive a detailed report with prioritized recommendations: fix this first (biggest impact), then this, then that. No guesswork.

Why Utah Homes Benefit More Than Most

Northern Utah's climate makes energy audits especially valuable:

Extreme temperature swings (100°F+ summers, sub-zero winters)
Your HVAC works harder than most climates → small efficiency improvements = big savings
Long heating season (4–6 months)
Heating accounts for 40–60% of Utah energy bills
Older housing stock
Many pre-1980 homes in Ogden, Layton, Logan are under-insulated by modern standards
Dry climate = more air leaks
Wood framing shifts and cracks more in low humidity
Basements common
Uninsulated rim joists are a major source of heat loss (easy to miss without audit)

💡 Utah Reality: Rocky Mountain Power reports that homes built before 1980 in Northern Utah average $2,000–$3,500/year in energy costs. After implementing audit recommendations, most homeowners save 20–35% — that's $400–$1,200 per year.

What You Get: Professional vs. DIY

Professional Audit ($200–$400)

Includes:

Blower door test: Measures total air leakage (pressurizes house, finds every leak)
Thermal imaging: Infrared camera shows heat loss/cold spots in real-time
Duct leakage test: Quantifies duct losses (often 20–30% in Utah homes)
Combustion safety test: Ensures furnace isn't backdrafting (carbon monoxide risk)
Insulation inspection: Measures R-value in attic, walls, basement
Written report: Prioritized recommendations with cost/savings estimates

Time commitment: 2–4 hours on-site, report within 1 week

DIY Audit (Free / Low Cost)

What you can check yourself:

Visual inspection: Look for obvious gaps, cracks, missing insulation
Incense stick test: Hold near windows/doors on windy day (watch smoke for drafts)
Hand test: Feel for air movement around outlets, baseboards, attic access
Utility bill analysis: Compare month-to-month and year-over-year usage
Thermostat check: Is it in a good location? Programmed efficiently?

Limitation: You'll find obvious problems but miss hidden issues (duct leaks, insulation voids, backdrafting risks).

Our take: DIY audit is a good starting point, but professional audit pays for itself if you implement even 2–3 major recommendations.

Typical Audit Findings in Utah Homes

Here's what energy auditors commonly find in Northern Utah (especially older homes):

Issue	Impact	Fix Cost
Insufficient attic insulation	15–25% heat loss	$1,500–$3,000
Duct leaks	20–30% energy waste	$500–$1,500
Air leaks (whole house)	10–20% heat loss	$200–$800 DIY
Uninsulated rim joists	10–15% heat loss	$200–$600 DIY
Old windows (single-pane)	10–25% heat loss	$3,000–$15,000
Thermostat issues	5–15% waste	$150–$300

Real Example: Ogden Home Audit

Home: 1,800 sq ft, 1975 construction, two-story, Ogden 84404

Annual energy costs (before): $2,400 ($140/month gas, $60/month electric)

Audit findings:

Attic insulation: R-19 (should be R-49 for Utah)
Duct leakage: 28% (should be <10%)
Rim joists: No insulation
Air leaks: Significant (blower door test showed 2,200 CFM50)
Thermostat: Old manual, poorly located (near fireplace)

Implemented fixes:

Added attic insulation to R-49 ($1,800)
Sealed duct leaks ($900 professional)
Insulated rim joists ($350 DIY)
Air-sealed obvious leaks ($150 DIY)
Upgraded thermostat, relocated ($280)

Total investment: $3,480

Annual savings: $720 (30% reduction)

Payback period: 4.8 years

How to Find an Energy Auditor in Utah

Option 1: Rocky Mountain Power (Subsidized)

If you're a Rocky Mountain Power customer (Weber, Cache, Box Elder counties):

Cost: Often free or heavily discounted ($0–$100)
What's included: Full professional audit + written report + rebate guidance
How to sign up: Call 1-888-221-7070 or visit wattsmart.com
Wait time: 2–6 weeks for appointment
Bonus: Access to wattsmart rebates for implementing recommendations

Option 2: Private Energy Auditor

For Dominion Energy customers (Davis County, some areas) or if you want faster service:

Cost: $200–$400 (not subsidized)
Certification to look for: BPI (Building Performance Institute) or RESNET HERS Rater
What to ask: "Do you use blower door and thermal imaging?" (Both are essential)
Local companies: Search "BPI certified energy auditor Utah"

Option 3: HVAC Contractor Energy Assessment

Some Utah HVAC companies offer basic energy assessments as part of a system replacement quote:

Pro: Often free if considering new HVAC
Con: Less comprehensive than dedicated energy audit
Con: May push equipment sales over cost-effective fixes

Quick Wins You Can Do Before an Audit

While waiting for your audit appointment, tackle these easy fixes:

Replace HVAC filter ($10–$25) — dirty filters waste 5–15% energy
Caulk obvious gaps ($5–$20) — windows, door frames, pipe penetrations
Add door sweeps ($10–$30 each) — especially exterior doors
Insulate attic access ($20–$50) — DIY foam board + weather-strip
Lower water heater temp (free) — 120°F is sufficient, saves $30–$50/year
Program thermostat (free) — 68°F occupied, 62°F away/sleeping in winter

These simple steps can save $100–$300/year immediately — and the audit will reveal where to focus next.

Is an Energy Audit Worth It?

Short answer: Yes, especially for homes built before 2000.

You should definitely get an audit if:

Energy bills are high compared to similar homes
Home is uncomfortable (cold spots, drafts, uneven temps)
You're planning to upgrade HVAC anyway (audit helps size system correctly)
Home was built before 1980
You're doing a major renovation (know what to fix first)
Considering solar (reduce energy use before adding panels = smaller system needed)

You might skip the audit if:

New construction (<5 years old) with modern efficiency standards
Recent comprehensive energy upgrades
Bills are already low for your home size
